フ ェ イ ス The face outlets 911a, 912a, 913a, and 914a are air-conditioning outlets that are provided in the vehicle compartment and blow out conditioned air when the air conditioner unit 11 performs air conditioning in the vehicle compartment. The face outlets 911a, 912a, 913a, and 914a are also abbreviated as face outlets 911a to 914a.

In addition to the face air outlets 911a to 914a, the vehicle cabin has an air-conditioning air outlet which is connected to a defroster air outlet through a defroster air duct and a foot air outlet through a foot duct. A connected foot outlet is provided.

The vehicle 80 also has a D-seat-side wind direction changing device 92 provided in the D-seat-side blowing section 911, and a P-seat-side wind direction changing device 93 provided in the P-seat-side blowing section 912. The D-seat side wind direction changing device 92 changes the blowing direction of the air blown out from the D-seat side face outlet 911a. For example, the D-seat-side wind direction changing device 92 has a louver and an actuator 921 provided in the D-seat-side side face outlet 911a. The blowing direction of 911a is changed.

Ｐ Then, the P-seat side wind direction changing device 93 changes the blowing direction of the air blown out from the P-seat side face outlet 912a. For example, the P-seat side wind direction changing device 93 has a louver and an actuator 931 provided in the P-seat side face outlet 912a, and the P-seat side face outlet is changed by changing the direction of the louver with the actuator 931. The blowing direction of 912a is changed.

Note that the louver of the D-seat-side wind direction changing device 92 is configured so that the direction of the louver can be manually changed freely when the D-seat-side wind direction changing device 92 is not energized to the actuator 921. The same applies to the louver of the P-seat side wind direction changing device 93.

The air conditioner control device 12 shown in FIG. 3 is configured by a microcomputer including a CPU, a ROM, a RAM, and the like (not shown). A signal from a sensor or the like connected to the air conditioner control device 12 is configured to be input to the air conditioner control device 12 after being A / D converted by an input circuit (not shown). For example, the signal lines connecting the air conditioner control device 12 and a plurality of connected devices such as sensors electrically connected to the air conditioner control device 12 may be respectively connected in parallel from the air conditioner control device 12 to each connected device. Alternatively, they may be connected in series. When the signal lines are connected in series, the LIN protocol or the like is used.

入 力 As shown in FIG. 3, a plurality of input-side connection devices 121 to 126 are electrically connected to the air conditioner control device 12. The plurality of input-side connected devices 121 to 126 are, for example, a D-seat-side door open / close sensor 121, a P-seat-side door open / close sensor 122, an outside air temperature sensor 123, a cancel switch 124, an ignition switch 125, and a battery voltage sensor 126. . The signals from the input side connection devices 121 to 126 may be input to the air conditioner control device 12 via a control device other than the air conditioner control device 12, or the other control devices may be used. The information may be directly input to the air conditioner control device 12 without passing through.

The D-seat-side door open / close sensor 121 detects whether the D-seat-side door 86 has opened the D-seat-side door opening 82. In short, the D-seat-side door open / close sensor 121 detects whether the D-seat side door 86 is open or closed. A detection signal indicating the open / closed state of the D-seat-side door 86 is input to the air-conditioner control device 12 from the D-seat-side door open / close sensor 121. Therefore, the air conditioner control device 12 recognizes that the D-seat-side door 86 has opened the D-seat-side door opening 82 based on the detection signal from the D-seat-side door open / close sensor 121.

The P-seat-side door opening / closing sensor 122 detects whether the P-seat-side door 88 has opened the P-seat-side door opening 84. In short, the P-seat-side door open / close sensor 122 detects whether the P-seat side door 88 is open or closed. A detection signal indicating the open / close state of the P seat side door 88 is input to the air conditioner control device 12 from the P seat side door open / close sensor 122. Therefore, the air conditioner control device 12 recognizes that the P-seat-side door 88 has opened the P-seat-side door opening 84 based on the detection signal from the P-seat-side door open / close sensor 122.

The outside air temperature sensor 123 detects the outside air temperature Tam, which is the temperature of the outside air around the vehicle 80. A detection signal indicating the outside air temperature Tam is input from the outside air temperature sensor 123 to the air conditioner control device 12.

The cancel switch 124 is an occupant operation switch operated by the occupant, and is provided at a location in the vehicle compartment, such as on the instrument panel 91, where the occupant can easily operate. Specifically, the cancel switch 124 is a switch for switching between permission and non-permission for executing the control process of FIG. 6 described later. In other words, the cancel switch 124 is a switch that switches between permission and non-permission for blowing air from the predetermined outlet Ps while the door 86 or 88 is open with any of the door openings 82 and 84 open. is there. Note that the side face outlets 911a and 912a correspond to the predetermined outlet Ps mentioned here.

The ignition switch 125 is a vehicle activation switch that switches on and off the occupant in order to make the vehicle 80 operable. Therefore, when the ignition switch 125 is turned off, the vehicle 80 is in a state where it cannot travel. Conversely, when the ignition switch 125 is turned on, the vehicle 80 is ready to run. For example, when the accelerator pedal is depressed after the ignition switch 125 is turned on, the vehicle 80 starts. Although the vehicle 80 of the present embodiment is an engine vehicle as described above, if the vehicle 80 is a hybrid vehicle or an electric vehicle, the ignition switch 125 is called, for example, a vehicle start switch.

(4) A signal indicating ON / OFF of the ignition switch 125 is input from the ignition switch 125 to the air conditioner control device 12. The ignition switch 125 may be, for example, an insertion key inserted into a keyhole or a push button. When the ignition switch 125 is turned off, the power of a predetermined on-board device such as an audio device mounted on the vehicle 80 is also turned off.

(4) The battery voltage sensor 126 detects a voltage Vb (in other words, a power supply voltage Vb) of a battery that is a power supply of the vehicle 80. A detection signal indicating the battery voltage Vb is input from the battery voltage sensor 126 to the air conditioner control device 12.

ＤThe D-seat-side wind direction changing device 92, the P-seat-side wind direction changing device 93, the air conditioner unit 11, and the like are electrically connected to the air conditioner control device 12 as output-side connection devices. For example, the air conditioner control device 12 outputs a control signal for controlling the operation of each of the D seat side wind direction changing device 92, the P seat side wind direction changing device 93, and the air conditioner unit 11. The control signal for the air conditioner unit 11 is, specifically, a control signal for controlling the operation of each component of the air conditioner unit 11 such as the blower 14.

(4) The air conditioner control device 12 executes a computer program stored in a semiconductor memory such as a ROM or a RAM which is a non-transitional substantial storage medium. When the computer program is executed, a method corresponding to the computer program is executed. That is, the air conditioner control device 12 executes various control processes such as the control process of FIG. 6 according to the computer program.

FIG. 6 is a flowchart showing a control process executed by the air conditioner control device 12 of the present embodiment. In the present embodiment, since the cancel switch 124 is provided, the air conditioner control device 12 performs the control process of FIG. 6 only when the execution of the control process of FIG. Execute The control process of FIG. 6 is periodically and repeatedly executed.

As shown in FIGS. 3 and 6, first, in step S011, the air conditioner control device 12 acquires signals from the outside air temperature sensor 123, the ignition switch 125, and the battery voltage sensor 126. Thus, the air conditioner control device 12 recognizes the outside air temperature Tam, the on / off state of the ignition switch 125, and the battery voltage Vb. After step S011, the process proceeds to step S021.

In step S021, the air conditioner control device 12 determines whether or not the outside air temperature Tam is equal to or higher than a predetermined lower limit of outside air temperature T1am and equal to or lower than a predetermined upper limit of outside air temperature T2am. The outside air temperature upper limit T2am is a temperature higher than the outside air temperature lower limit T1am.

The outside temperature lower limit T1am and the outside temperature upper limit T2am are experimentally determined in advance so that the temperature range from the outside temperature lower limit T1am to the outside temperature upper limit T2am matches the temperature range in which mosquitoes fly. This is because the control processing of FIG. 6 is executed to prevent foreign substances such as mosquitoes from entering the vehicle interior.

If it is determined in step S021 that the outside air temperature Tam is equal to or higher than the outside air temperature lower limit T1am and equal to or lower than the predetermined outside air temperature upper limit T2am, the process proceeds to step S031. On the other hand, if it is determined that the outside air temperature Tam is lower than the outside air temperature lower limit T1am, or if it is determined that the outside air temperature Tam is higher than the outside air temperature upper limit T2am, the process proceeds to step S171.

In step S031, the air conditioner control device 12 determines whether the battery voltage Vb is equal to or higher than a predetermined voltage determination value V1b. The voltage determination value V1b is experimentally determined in advance so that if the battery voltage Vb is lower than the voltage determination value V1b, it can be determined that the battery is undercharged.

If it is determined in step S031 that the battery voltage Vb is equal to or higher than the voltage determination value V1b, the process proceeds to step S041. On the other hand, when it is determined that the battery voltage Vb is lower than the voltage determination value V1b, the process proceeds to step S171.

に お い て In step S041, the air conditioner control device 12 determines whether or not the ignition switch 125 is off (ie, OFF).

If it is determined in step S041 that the ignition switch 125 is off, the process proceeds to step S051. On the other hand, when it is determined that the ignition switch 125 is not off, the process proceeds to step S171. The case where the ignition switch 125 is not off is assumed to be the case where the ignition switch 125 is on or the case where the ignition switch 125 is switched to another switch state which is neither on nor off.

に お い て In step S051, the air conditioner control device 12 acquires a signal from the D-seat-side door opening / closing sensor 121. Thereby, the air conditioner control device 12 recognizes the open / closed state of the D-seat side door 86 shown in FIG.

エ ア コ ン Then, the air conditioner control device 12 determines whether or not the D-seat side door 86 is opening the D-seat side door opening 82.

If it is determined in step S051 that the D-seat-side door opening 82 is opening the door, the flow proceeds to step S071. On the other hand, if it is determined that the D-seat-side door opening 82 is not opening the door, the process proceeds to step S061. Specifically, the case where the D-seat-side door opening 82 is not open is the case where the D-seat-side door 86 is closing the D-seat-side door opening 82 with the D-seat-side door 86. .

お よ び As shown in FIGS. 3 and 6, in step S061, the air conditioner control device 12 acquires a signal from the P-seat-side door open / close sensor 122. Thereby, the air conditioner control device 12 recognizes the open / closed state of the P seat side door 88 shown in FIG.

Then, the air conditioner control device 12 determines whether or not the P-seat-side door opening 88 is being opened by the P-seat-side door 88.

If it is determined in step S061 that the P-seat-side door opening 84 is open, the process proceeds to step S131. On the other hand, when it is determined that the P-seat-side door opening 84 is not opening the door, the process proceeds to step S171. Specifically, the case where the P-seat-side door opening 84 is not being opened is a case where the P-seat-side door 88 is closing the P-seat-side door opening 84 with the P-seat-side door 88. .

As shown in FIGS. 3 and 6, in step S071, the air conditioner control device 12 prevents the air conditioner unit 11 from invading foreign matter such as mosquitoes from the door openings 82 and 84 while the door is open. To a predetermined intrusion prevention mode for If the air conditioner unit 11 is already in the intrusion prevention mode, the air conditioner unit 11 is continued in the intrusion prevention mode.

Specifically, in the intrusion prevention mode, the suction mode of the air conditioner unit 11 is set to the outside air mode. The door position of the air mix door 26 is set to the MAXCOOL position. The air blowing mode of the air conditioner unit 11 is a face mode. The face mode is a mode in which air is exclusively blown out from the face blowing openings 191a, 191b, 191c, and 191d, and the opening and closing of the face doors 28, 30, and 32 follow steps S091, S111, and S141 described later. Therefore, in step S071, the air conditioner control device 12 does not operate the face doors 28, 30, and 32, and closes the defroster door 33 and the foot door 34. After step S071, the process proceeds to step S081.

に お い て In step S081, the air conditioner control device 12 performs the same processing as in step S061 described above. That is, the air conditioner control device 12 recognizes the open / closed state of the P seat side door 88 shown in FIG. 1 based on the signal from the P seat side door open / close sensor 122. Then, the air conditioner control device 12 determines whether or not the P-seat-side door opening 84 is opening the door.

If it is determined in step S081 that the P-seat-side door opening 84 is being opened, the process proceeds to step S111. On the other hand, when it is determined that the P-seat-side door opening 84 is not opening the door, the process proceeds to step S091.

お よ び As shown in FIGS. 3 and 6, in step S091, the air conditioner control device 12 sets the face blowout openings 191a, 191b, 191c, and 191d to the D seat side open state. If the face blowing openings 191a, 191b, 191c, and 191d are already in the D-seat side open state, the operation is continued in the D-seat side open state.

Specifically, in the D-seat-side open state, the D-seat-side side face opening 191a is opened by the D-seat-side side face door. On the other hand, the P-seat side face opening 191 b is closed by the P-seat side face door 30, and the center face openings 191 c and 191 d are closed by the center face door 32. Therefore, after the process of step S091 is completed, all the blowout openings other than the D-side seat side face blowout opening 191a are closed. After step S091, the process proceeds to step S101.

FIG. 4 shows the D-side open state of the face blowout openings 191a, 191b, 191c, and 191d. Specifically, in FIG. 4, the point hatching provided on the P-seat side side face opening 191b and the center face opening 191c, 191d is such that the opening 191b, 191c, 191d is closed. It is shown that. In addition, the fact that the hatching indicates that the blowout opening is closed is the same in the following drawings similar to FIG. 4.

In step S101 in FIG. 6, the air conditioner control device 12 sets the D-seat side wind direction changing device 92 to direct the blowout direction of the D-seat side face face outlet 911a to the outside of the cabin through the D-seat side door opening 82. To the outside air outlet mode. As a result, as shown in FIGS. 1 and 4, the D-seat-side side face outlet 911 a allows air to flow from the interior of the vehicle to the exterior of the D-seat-side door opening 82 via the D-seat-side door opening 82. Outlet. In other words, the D-seat-side side face outlet 911a is an outlet that blows air from the vehicle interior side to the D-seat side door opening 82 so as to pass through the D-seat side door opening 82 to the outside of the vehicle. . For example, as shown in FIG. 1, the blowout direction of the D-seat-side side face blowout port 911a in the outward blowout mode is a direction facing the rear side of the vehicle and the diagonally right side of the vehicle, and the blowout direction is experimentally determined in advance. Stipulated. After step S101, the process proceeds to step S161.

Here, since the blower 14 is operated in step S161 described later, if step S161 is executed following step S101, the D-side seat side face blower is exclusively used as shown by the arrow Ard in FIGS. Air is blown out from the outlet 911a. In the present embodiment, the D-seat-side side face outlet 911a and the P-seat-side side face outlet 912a correspond to the predetermined outlet Ps. That is, in the present embodiment, two predetermined outlets Ps are provided.

Therefore, in step S101, the air conditioner control device 12 controls the D-seat-side wind direction changing device 92 when blowing air from the predetermined outlet Ps while the door of the D-seat-side door opening 82 is open. It can be said that the blowing direction of the predetermined outlet Ps is directed to the outside of the vehicle compartment.

The signals transmitted and received by the air conditioner control device 12 when step S161 is executed following step S101 are exemplified in FIGS. 7 and 8. “I / G” shown in FIG. 8 is an abbreviation for an ignition switch.

お よ び As shown in FIGS. 3 and 6, in step S111, the air conditioner control device 12 sets the face blowout openings 191a, 191b, 191c, and 191d to the open state on both sides. If the face blowing openings 191a, 191b, 191c, and 191d are already open on both sides, the operation is continued in the open state on both sides.

Specifically, in the both-side open state, the D-seat-side side face opening 191a is opened by the D-seat-side side face door 28, and the P-seat-side side-face opening 191b is connected to the P-seat-side side face door 30. Opened by On the other hand, the center face blowing openings 191c and 191d are closed by the center face door 32. Therefore, after the process of step S111 is completed, all the blowout openings other than the side face blowout openings 191a and 191b on the seat D side and the seat P side are closed. After step S111, the process proceeds to step S121.

FIG. 9 shows a state in which both sides of the face blowing openings 191a, 191b, 191c, and 191d are open. Specifically, in FIG. 9, dot hatching given to the center face blowout openings 191c and 191d indicates that the center face blowout openings 191c and 191d are closed.

エ ア コ ン In step S121 in FIG. 6, the air conditioner control device 12 sets the D-seat side wind direction changing device 92 to the outward air outlet mode as in step S101 described above.

に In addition, the air conditioner control device 12 also sets the P-seat side wind direction changing device 93 to the predetermined outward air outlet mode. In the outward air outlet mode of the P-seat side wind direction changing device 93, the P-seat side air direction changing device 93 adjusts the blowing direction of the P-seat side side face outlet 912a to the outside of the vehicle cabin through the P-seat side door opening 84. To. As a result, as shown in FIGS. 1 and 9, the P-seat-side side face outlet 912 a allows air to flow from the inside of the cabin to the outside of the cabin with respect to the P-seat side door opening 84 via the P-seat side door opening 84. Outlet. In other words, the P-seat-side side face outlet 912a is an outlet that blows air from the inside of the vehicle with respect to the P-seat-side door opening 84 to the outside of the cabin through the P-seat-side door opening 84. . For example, the blowout direction of the P-seat side face blowout port 912a in the outward blowout mode is a direction facing the rear side of the vehicle and the diagonally left side of the vehicle, and the blowout direction is experimentally determined in advance. After step S121, the process proceeds to step S161.

Here, in step S161 described later, the blower 14 is operated. Therefore, when step S161 is executed following step S121, air is exclusively blown out from the D- and P-seat side face outlets 911a and 912a as indicated by arrows Ard and Arp in FIG. . As described above, in the present embodiment, the D-seat-side side face outlet 911a and the P-seat-side side face outlet 912a correspond to the predetermined outlet Ps.

Therefore, it can be said that the air conditioner control device 12 performs the following in step S121. That is, when air is blown out from the predetermined air outlet Ps while the doors of the D-seat side and P-seat side door openings 82 and 84 are open, the air conditioner control device 12 sets the D-seat-side and P-seat-side wind direction change devices 92. , 93 can be said to direct the blowing direction of the predetermined outlet Ps toward the outside of the vehicle compartment.

As shown in FIGS. 3 and 6, in step S131, the air conditioner control device 12 performs the same processing as in step S071 described above. That is, the air conditioner control device 12 sets the air conditioner unit 11 to the intrusion prevention mode. If the air conditioner unit 11 is already in the intrusion prevention mode, the air conditioner unit 11 is continued in the intrusion prevention mode. After step S131, the process proceeds to step S141.

に お い て In step S141, the air conditioner control device 12 sets the face outlet openings 191a, 191b, 191c, 191d to the P seat side open state. If the face blowing openings 191a, 191b, 191c, and 191d are already in the P-seat side open state, the P-seat side open state is continued.

Specifically, in the P-seat-side open state, the P-seat-side side face opening 191b is opened by the P-seat-side side face door 30. On the other hand, the D-seat side face face opening 191a is closed by the D-seat side face door 28, and the center face blowing openings 191c and 191d are closed by the center face door 32. Therefore, after the completion of the process in step S141, all the blowout openings except the P-seat side face blowout opening 191b are closed. After step S141, the process proceeds to step S151.

In step S151, the air conditioner control device 12 sets the P-seat side wind direction changing device 93 to the outward air outlet mode as in step S121 described above. However, unlike step S121, the air conditioner control device 12 does not operate the D-seat-side wind direction changing device 92. After step S151, the process proceeds to step S161.

Here, in step S161 described later, the blower 14 is operated. Therefore, when step S161 is executed following step S151, air is exclusively blown from the P-seat-side side face outlet 912a as indicated by an arrow Arp in FIG. As described above, in the present embodiment, the D-seat-side side face outlet 911a and the P-seat-side side face outlet 912a correspond to the predetermined outlet Ps.

Therefore, it can be said that the air conditioner control device 12 performs the following in step S151. That is, the air conditioner control device 12 controls the P-seat-side wind direction changing device 93 to blow air from the predetermined outlet Ps while the door of the P-seat-side door opening 84 is open, thereby controlling the predetermined outlet. It can be said that the blowing direction of Ps is directed to the outside of the passenger compartment.

In step S161, the air conditioner control device 12 activates the blower 14 and causes the blower 14 to blow air. For example, the air conditioner control device 12 operates the blower 14 to blow at the maximum air volume. If the blower 14 is already operating, the operation is continued.

に お い て In step S171, the air conditioner control device 12 stops the blower 14 which has been activated in step S161. If the blower 14 is already stopped, it is continued. Note that the processing in step S171 does not stop the blower 14 when the blower 14 is operating in a control process other than the control process in FIG. After steps S161 and S171, the process returns to step S011.

(6) The air conditioner control device 12 performs the control processing of FIG. 6 as described above. As a result, the air conditioner control device 12 operates the blower 14 while the door of the D-seat side door opening 82 is open as shown in FIG. Through the D-seat side face outlet 911a.

In the control process of FIG. 6, the air conditioner control device 12 activates the blower 14 while the door of the P-seat side door opening 84 is open, and sends the air flowing from the blower 14 to the P-seat side face duct 40. And blows out from the P-seat side face outlet 912a.

For example, a case where the occupant tries to get on from the D-seat side door opening 82 will be described as an example. In this case, the occupant opens the D-seat side door 86 as shown in FIG. When the D-seat side door 86 is opened in this way, if all the determinations in steps S021 to S041 in FIG. 6 are “YES”, the blower 14 sucks in the outside air as indicated by the arrow Ari in FIG. The sucked air (specifically, outside air) passes through the evaporator 22 and the bypass passage 19c of FIG. 5 in order from the blower 14 and flows out of the D-side seat side face opening 191a of FIG.

The air that has flowed out from the D-seat-side side face outlet 191a is blown out from the D-seat-side side face outlet 911a through the D-seat-side side face duct 39, as indicated by the arrow Ard in FIGS. . Then, the mosquito 99, for example, is blown off to the outside of the cabin when the mosquito 99 tries to enter the cabin due to the wind flow blown out from the D seat side side face outlet 911a as shown by the arrow Ard. Thereafter, when the occupant gets on the D-seat side door opening 82 and closes the D-seat side door 86, the blower 14 is stopped in step S171 in FIG. When the occupant switches on the ignition switch 125, step S161 is not executed according to the determination in step S141 in FIG. 6, so that the air conditioner unit 11 can return to normal air conditioning in the vehicle compartment.

The above-described processing in each step in FIG. 6 constitutes a functional unit for realizing each function, and the air conditioner control device 12 includes the functional unit. This is the same in a flowchart described later.

As described above, according to the present embodiment, the air conditioner control device 12 executes the control process shown in FIG. Thereby, while the door of the D-seat side door opening 82 in FIG. 1 is open, the air conditioner control device 12 activates the blower 14, and the air flowing from the blower 14 passes through the D-seat side side face duct 39 to the predetermined position. The air is blown out from the D-seat-side side face air outlet 911a as the air outlet Ps. At this time, the D-seat-side side face outlet 911a blows air through the D-seat-side door opening 82 from the cabin side to the D-seat-side door opening 82 when the door is open.

In addition, while the door of the P-seat side door opening 84 is open, the air conditioner control device 12 activates the blower 14 and sends the air flowing from the blower 14 to the predetermined outlet Ps through the P-seat side face duct 40. From the P-seat side face outlet 912a. At this time, the P-seat side face outlet 912a blows air through the P-seat side door opening 84 from the inside of the vehicle to the P-seat side door opening 84 when the door is open.

Therefore, when a foreign substance such as a mosquito 99 attempts to enter the vehicle interior from the door openings 82 and 84 while the door is being opened, the foreign substance is blown to the outside of the vehicle interior by the airflow from the predetermined outlet Ps. As described above, it is possible to prevent foreign substances from entering the vehicle interior from the door openings 82 and 84 while the door is being opened.

{Circle around (2)} The air conditioning air flowing out of the air conditioner unit 11 when the air conditioner unit 11 air-conditions the vehicle interior also flows through the side face ducts 39 and 40, which are the air conditioning ducts to which the predetermined outlet Ps is connected. Therefore, a special duct is not required to blow air from the predetermined outlet Ps for the purpose of suppressing intrusion of foreign matter into the vehicle interior, and the side face duct 39 used for air conditioning in the vehicle interior is not required. , 40 can be diverted. Therefore, it is possible to improve the mountability of the air blowing device 10 on the vehicle 80.

Further, according to the present embodiment, as shown in FIGS. 4 and 9, the D-seat-side side face outlet 911a as the predetermined outlet Ps is used when the air conditioner unit 11 performs air conditioning in the vehicle interior. The conditioned air that has passed through the seat-side side face duct 39 is blown out. The P-seat-side side face outlet 912a serving as the predetermined outlet Ps blows out conditioned air that has passed through the P-seat side face duct 40 when the air conditioner unit 11 performs air conditioning of the vehicle interior.

Therefore, the predetermined outlet Ps is not a dedicated outlet for blowing out air for the purpose of suppressing intrusion of foreign matter into the vehicle interior. That is, the air conditioning side face outlets 911a and 912a used for air conditioning in the vehicle cabin can be used as the predetermined outlet Ps. Therefore, it is possible to improve the mountability of the air blowing device 10 on the vehicle 80. Further, since the number of components can be reduced as compared with the case where a dedicated air outlet is provided as the predetermined air outlet Ps, the cost of the air blowing device 10 can be reduced.

Further, according to the present embodiment, as shown in FIGS. 6 and 8, the air conditioner control device 12 performs a process of blowing air from the predetermined outlet Ps while one or both of the door openings 82 and 84 are open. Do the following: That is, the air conditioner control device 12 controls the one or both of the D-seat-side and P-seat-side wind direction change devices 92 and 93 to blow out the air in such a manner, thereby changing the blowout direction of the predetermined blowout port Ps. Turn to the outside of the cabin.

Therefore, in order to prevent foreign substances such as mosquitoes from entering the vehicle interior through the door openings 82 and 84 during opening of the door, the blowing directions of the air-conditioning side face air outlets 911a and 912a used as the predetermined air outlet Ps. Can be oriented appropriately.

Further, according to the present embodiment, as shown in FIGS. 5 and 6, the air conditioner control device 12 performs a process of blowing air from the predetermined outlet Ps while one or both of the door openings 82 and 84 are open. , The air mix door 26 opens the bypass passage 19c. Specifically, the air conditioner control device 12 sets the door position of the air mix door 26 to the MAXCOOL position.

Therefore, it is possible to prevent the heater core 24 from increasing the ventilation resistance in the air conditioner unit 11 when blowing air from the predetermined outlet Ps while the door is open. As a result, it is possible to increase the amount of air blown from the predetermined outlet Ps while the door is open.

According to the present embodiment, as shown in FIGS. 1 and 6, the air conditioner control device 12 controls the air conditioner 12 to blow air from the predetermined outlet Ps while one or both of the door openings 82 and 84 are open. , The air conditioner unit 11 is set to the outside air mode. Therefore, it is possible to prevent the air blown out from the predetermined outlet Ps from being drawn into the vehicle interior by the blower 14. As a result, for example, compared with the case where the air conditioner unit 11 is in the inside air mode, it is possible to improve the performance of preventing foreign substances from entering the vehicle interior from the door openings 82 and 84 while the door is open.
Further, when the occupant gets on the vehicle from the opened door openings 82 and 84, the air in the vehicle compartment is forcibly ventilated by blowing out the outside air from the predetermined air outlet Ps. Therefore, for example, when it is assumed that an occupant gets on a car after parking for a long time under the scorching sun, it is possible to quickly ventilate the hot air in the passenger compartment when the occupant gets on the board, and to quickly cool down after the occupant and reduce the air conditioning load. Has the effect.

According to the present embodiment, the center face outlets 913a and 914a are different from the predetermined outlet Ps. When air is blown out from the predetermined air outlet Ps while one or both of the door openings 82 and 84 are open, the air conditioner control device 12 transmits air from the center face air outlets 913a and 914a to the vehicle interior. Stop blowing. Therefore, in response to stopping the air flow to the center face outlets 913a and 914a, which are some distance from the door openings 82 and 84, it is possible to secure a large amount of air blown out from the predetermined outlet Ps. It is possible.

According to the present embodiment, the flowchart of FIG. 6 includes step S021 for determining the outside air temperature Tam. That is, the air conditioner control device 12 opens one or both of the door openings 82 and 84 on the condition that the outside air temperature Tam is equal to or higher than the predetermined lower limit value T1am and equal to or lower than the predetermined upper limit value T2am. The air is blown out from the predetermined outlet Ps.

Therefore, in a situation in which the activity of pests such as mosquitoes 99, which are representative examples of foreign matter that can enter the vehicle interior from the door openings 82 and 84, is stagnant, air is blown out from the predetermined outlet Ps while the door is open. Will not be implemented. Therefore, when the necessity of suppressing the entry of foreign matter into the vehicle interior from the door openings 82 and 84 while the door is open increases, it is necessary to blow air from the predetermined outlet Ps while the door is open. It can be implemented as appropriate.

Further, according to the present embodiment, as shown in FIGS. 3 and 8, the air conditioner control device 12 sets the D-seat side door 86 based on the detection signal from the D-seat side door open / close sensor 121. It recognizes that the opening 82 has been opened. Then, the air conditioner control device 12 recognizes that the P seat side door 88 has opened the P seat side door opening 84 based on the detection signal from the P seat side door open / close sensor 122. Therefore, the air conditioner control device 12 can easily obtain information on whether or not the D-seat side doors 86 and the P-seat side doors 86 have opened the door openings 82 and 84, respectively.

According to the present embodiment, as shown in FIG. 3, the vehicle 80 is provided with the cancel switch 124 as an occupant operation switch. Only when the execution of the control process of FIG. 6 is permitted by the occupant operation on the cancel switch 124, the air conditioner control device 12 executes the control process of FIG. That is, specifically, the air conditioner control device 12 performs the predetermined operation while the door is opened only when it is permitted by the occupant to operate the cancel switch 124 to blow air from the predetermined outlet Ps while the door is open. Air is blown out from the outlet Ps. Therefore, it is possible to stop blowing air from the predetermined outlet Ps while the door is open, according to the occupant's intention.

According to the present embodiment, the flowchart of FIG. 6 includes step S031 for determining the battery voltage Vb. That is, the air conditioner control device 12 blows air from the predetermined outlet Ps while one or both of the door openings 82 and 84 are open, provided that the battery voltage Vb is equal to or higher than the predetermined voltage determination value V1b. .

Therefore, when the battery mounted on the vehicle 80 is weak, it is possible to stop blowing air from the predetermined outlet Ps while the door is open. In the present embodiment, since the blowing of air from the predetermined outlet Ps while the door is open is performed when the ignition switch 125 is off, it is particularly effective to perform the determination regarding the battery voltage Vb in step S031. .

These outlet switching devices 94 and 95 are each electrically connected to the air conditioner control device 12 as output-side connection devices. The operation of the outlet switching devices 94 and 95 is controlled by the air conditioner controller 12.

Since the D-seat-side outward blowout portion 915 forms a part of the D-seat-side side wall 91a, the D-seat-side outward blowout port 915a is formed in the D-seat-side side wall 91a. Therefore, the D-seat-side outward air outlet 915a is formed in the instrument panel 91 at a position closer to the right end than the D-seat-side side face air outlet 911a in the vehicle left-right direction DR2.

Since the P-seat-side outward blowout portion 916 forms a part of the P-seat-side side wall 91b, the P-seat-side outward blowout port 916a is formed in the P-seat-side side wall 91b. Therefore, the P-seat-side outward air outlet 916a is formed at a position on the instrument panel 91 closer to the left end than the P-seat-side side face air outlet 912a in the vehicle left-right direction DR2. Since the D-seat side and P-seat side outward air outlets 915a and 916a are both provided in a part of the instrument panel 91, they are provided in the vehicle interior.

As shown in FIG. 10, the D-seat-side outward air outlet 915a is connected to the downstream side of the air flow of the D-seat-side side face duct 39 in parallel with the D-seat-side side face air outlet 911a that is an air-conditioning air outlet. I have. Specifically, the D-seat-side outward air outlet 915a and the D-seat-side side face air outlet 911a are respectively connected to the outlet end 392 of the D-seat-side side face duct 39 via the D-seat-side air outlet switching device 94. ing.

The D-seat-side outlet switching device 94 sets the ventilation path such that the air that has passed through the D-seat-side side face duct 39 flows to either the D-seat-side outward outlet 915a or the D-seat-side side face outlet 911a. Switch. That is, the D-seat-side outlet switching device 94 selectively switches between the first communication state and the second communication state. The D-seat-side outlet switching device 94 in the first communication state allows the outlet end 392 of the D-seat side face duct 39 to communicate with the D-seat side face outlet 911a, while the outlet end 392 is provided. And the communication between the D-seat-side outward air outlet 915a. Conversely, the D-seat-side outlet switching device 94 in the second communication state allows the outlet end 392 of the D-seat-side side face duct 39 to communicate with the D-seat-side outward outlet 915a, and at the same time, the outlet end thereof. Communication between 392 and the D-seat-side side face outlet 911a is cut off.

The P-seat-side outward air outlet 916a is connected to the P-seat-side side face duct 40 downstream of the airflow in parallel with the P-seat-side side face air outlet 912a, which is an air-conditioning air outlet. More specifically, the P-seat side outward air outlet 916a and the P-seat side air outlet 912a are connected to the outlet end 402 of the P-seat side face duct 40 via the P-seat air outlet switching device 95, respectively. ing.

The P-seat-side outlet switching device 95 sets the ventilation path so that the air passing through the P-seat-side side face duct 40 flows to either the P-seat-side outward outlet 916a or the P-seat-side side face outlet 912a. Switch. That is, the P-seat-side outlet switching device 95 selectively switches between the first communication state and the second communication state. The P-seat-side outlet switching device 95 in the first communication state connects the outlet end 402 of the P-seat side face duct 40 with the P-seat side face outlet 912a, while the outlet end 402 thereof. And the communication between the P-seat side outward air outlet 916a. Conversely, the P-seat-side outlet switching device 95 in the second communication state allows the outlet end 402 of the P-seat side face duct 40 to communicate with the P-seat-side outward outlet 916a, while having the outlet end thereof. The communication between 402 and the P-seat-side side face outlet 912a is blocked.

(4) When the air conditioner unit 11 performs air conditioning in the passenger compartment, the air conditioner control device 12 sets the D-seat side and P-seat side air outlet switching devices 94 and 95 to the first communication state, respectively. For example, the D-seat side and P-seat side outlet switching devices 94 and 95 may be brought into the second communication state by the control process of FIG. 13 described later. When the air outlet switching devices 94 and 95 are in the second communication state in this way, the air conditioner control device 12 controls the air outlet switching devices 94 and 95 when the air conditioning unit 11 starts air conditioning in the vehicle compartment. 95 are switched from the second communication state to the first communication state.

The D-seat-side outward air outlet 915a and the P-seat-side outward air outlet 916a are air outlets dedicated to blowing air by the control process of FIG. 13 described later, and are used when the air conditioner unit 11 performs air conditioning of the vehicle interior. Is not used. That is, the D-seat-side outward air outlet 915a and the P-seat-side outward air outlet 916a are air outlets different from the air-conditioning air outlets such as the face air outlets 911a to 914a. Therefore, the blowing direction of the air blown out from the D-seat side outward blowout port 915a and the blowout direction of the air blowing out from the P-seat side outward blowout port 916a are respectively fixed blowout directions.

Specifically, the D-seat-side outward air outlet 915a is configured such that the outlet direction of the D-seat-side outward air outlet 915a is such that the door is open from the vehicle interior side to the D-seat side door opening 82 to the outside of the vehicle interior. It is configured in advance so as to blow air through the seat-side door opening 82. The P-seat-side outward air outlet 916a has a P-seat-side outward air outlet 916a in which a P-seat-side door is open from the interior of the vehicle to the exterior of the cabin with respect to the P-seat-side door opening 84. It is configured in advance so as to blow air through the opening 84.

FIG. 13 is a flowchart showing a control process executed by the air conditioner control device 12 of the present embodiment. As in the first embodiment, also in the present embodiment, the air conditioner control device 12 performs the control process of FIG. 13 only when the execution of the control process of FIG.

FIG. 13 is a flowchart corresponding to FIG. 6 of the first embodiment. Steps S101, S121, and S151 in FIG. 6 are replaced with steps S102, S122, and S152 in FIG. 13, steps having the same contents as those in FIG. 6 are denoted by the same reference numerals, and description thereof will be omitted.

In the flowchart of FIG. 13, after step S091, the process proceeds to step S102. In step S102, the air conditioner control device 12 sets the D-seat side outlet switching device 94 to the second communication state. Thereby, the air conditioner control device 12 can flow the air that has passed through the D-seat side side face duct 39 to the D-seat side outward air outlet 915a. If the D-seat-side outlet switching device 94 is already in the second communication state, the operation is continued as it is. After step S102, the process proceeds to step S161.

Here, since the blower 14 is operated in step S161 in FIG. 13, if step S161 is executed following step S102, the outside of the seat D is exclusively directed outward as indicated by the arrow Ard in FIGS. Air is blown out from the outlet 915a. That is, in this case, air is blown out from the D-seat-side outward blowout port 915a as the predetermined blowout port Ps.

In the flowchart of FIG. 13, after step S111, the process proceeds to step S122. In step S122, the air conditioner control device 12 sets the D-seat-side and P-seat-side outlet switching devices 94 and 95 to the second communication state, respectively. Thereby, the air conditioner control device 12 can flow the air that has passed through the D-seat side side face duct 39 to the D-seat side outward air outlet 915a. Then, the air conditioner control device 12 can flow the air that has passed through the P-seat-side side face duct 40 to the P-seat-side outward air outlet 916a.

If the D-seat-side outlet switching device 94 is already in the second communication state, the operation is continued as it is. If the P-seat-side outlet switching device 95 is already in the second communication state, the operation is continued as it is. After step S122, the process proceeds to step S161.

Here, in step S161 in FIG. 13, the blower 14 is operated. Therefore, when step S161 is executed following step S122, air is exclusively blown out of the D-seat side and P-seat side outward air outlets 915a and 916a as indicated by arrows Ard and Arp in FIG. That is, in this case, air is blown out from the D-seat side and P-seat side outward air outlets 915a and 916a as the predetermined air outlets Ps.

In the flowchart of FIG. 13, after step S141, the process proceeds to step S152. In step S152, the air conditioner control device 12 sets the P-seat side outlet switching device 95 to the second communication state. Thereby, the air conditioner control device 12 can flow the air that has passed through the P-seat side face duct 40 to the P-seat side outward air outlet 916a. If the P-seat-side outlet switching device 95 is already in the second communication state, the operation is continued as it is. After step S152, the process proceeds to step S161.

Here, since the blower 14 is operated in step S161 in FIG. 13, if step S161 is executed following step S152, the P-seat side outward air outlet 916a is exclusively used as shown by the arrow Arp in FIG. Air is blown out from the. That is, in this case, the air is blown out from the P-seat-side outward blowout port 916a as the predetermined blowout port Ps.

(5) The air conditioner control device 12 performs the control process of FIG. 13 as described above. Accordingly, the air conditioner control device 12 performs the following when blowing out the air from the D-seat side outward air outlet 915a while the door of the D-seat side door opening 82 is open. That is, the air conditioner control device 12 controls the D-seat-side air outlet switching device 94 to blow air through the D-seat side side face duct 39 to the D-seat side outward when blowing air in such a manner. Flow to outlet 915a.

Similarly, on the P-seat side, the air conditioner control device 12 performs the following when blowing air from the P-seat-side outward air outlet 916a while the P-seat-side door opening 84 is open. . In other words, the air conditioner control device 12 controls the P-seat-side outlet switching device 95 to blow out the air passing through the P-seat side face duct 40 to the P-seat side outward when the air is blown out as described above. Flow to outlet 916a.

As described above, according to the present embodiment, the D-seat-side outward air outlet 915a is provided as an air outlet different from the air-conditioning air outlets 911a to 914a. The blowout direction of the D-seat-side outward blowout port 915a is fixed. Specifically, the D-seat-side outward air outlet 915a is configured such that the outlet direction of the D-seat-side outward air outlet 915a is such that the door is open from the vehicle interior side to the D-seat side door opening 82 to the outside of the vehicle interior. It is configured in advance so as to blow air through the seat-side door opening 82. Therefore, it is not necessary to provide the D-seat-side outward outlet 915a with a function of changing the outlet direction, and the D-seat-side outward outlet 915a can be simply formed. Thus, for example, there is a merit that the performance of preventing foreign substances from entering the vehicle interior from the D-seat-side door opening 82 during opening of the door can be easily improved. This is the same for the P-seat-side outward air outlet 916a.

According to the present embodiment, the air conditioner control device 12 executes the control process shown in FIG. Accordingly, the air conditioner control device 12 performs the following when blowing out the air from the D-seat side outward air outlet 915a while the door of the D-seat side door opening 82 is open. That is, the air conditioner control device 12 controls the D-seat-side air outlet switching device 94 to blow air through the D-seat side side face duct 39 to the D-seat side outward when blowing air in such a manner. Flow to outlet 915a. The D-seat-side outward air outlet 915a is connected to the airflow downstream side of the D-seat-side side face duct 39 in parallel with the D-seat-side side face air outlet 911a, which is an air-conditioning air outlet.

Therefore, it is possible to provide the D-seat-side outward air outlet 915a as a dedicated air outlet for preventing foreign substances from entering the vehicle interior from the D-seat-side door opening 82 while the door is open. Therefore, the D-seat side outward air outlet 915a can have a nozzle shape suitable for preventing foreign substances such as mosquitoes 99 from entering the vehicle interior from the D-seat side door opening 82 when the door is open. It is. As a result, for example, it is possible to improve the performance of preventing foreign substances from entering the vehicle interior from the D-seat-side door opening 82 during opening of the door. This is the same for the P-seat-side outward air outlet 916a.

流出 Also, it is possible to automatically switch the outflow destination of the air from the D-seat side face duct 39 to the D-seat side outward air outlet 915a and the D-seat side face air outlet 911a. The same applies to the outflow destination of air from the P-seat side face duct 40.

Further, according to the present embodiment, the D-seat-side outward air outlet 915a is formed in the instrument panel 91 at a position closer to the right end than the D-seat-side side face air outlet 911a in the vehicle left-right direction DR2. I have. The P-seat-side outward air outlet 916a is formed at a position on the instrument panel 91 closer to the left end than the P-seat-side side face air outlet 912a in the vehicle left-right direction DR2.

Accordingly, the outward air outlets 915a and 916a on the D-seat side and the P-seat side are less noticeable from the occupant in the passenger compartment, so that the influence on the design in the passenger compartment can be reduced. Further, it is easy to improve the vehicle mountability of the components forming the respective outward blowout ports 915a and 916a.

Further, according to the present embodiment, the D-seat-side side wall 91a of the instrument panel 91 is covered by the D-seat-side door 86 in a state where the D-seat-side door opening 82 is closed, and the D-seat-side outward air outlet 915a. Are formed on the side wall 91a on the D seat side. Further, the P-seat-side side wall 91b of the instrument panel 91 is covered by a P-seat-side door 88 in a state where the P-seat-side door opening 84 is closed. Is formed. Therefore, the doors 86, 88 with the door openings 82, 84 closed, make the outward air outlets 915a, 916a invisible to occupants in the vehicle interior, respectively, so that the influence on the design in the vehicle interior can be reduced. .

Except as described above, this embodiment is the same as the first embodiment. Further, in the present embodiment, the effects obtained from the configuration common to the above-described first embodiment can be obtained in the same manner as the first embodiment.

Therefore, the control unit of the in-vehicle wireless device 89 can determine whether or not the portable device 891 has approached the vehicle 80 and has entered the predetermined area Ax around the vehicle. Information indicating the determination result is input to the air conditioner control device 12 as a signal from the on-board wireless device 89.

FIGS. 16A and 16B are flowcharts showing control processing executed by the air conditioner control device 12 of the present embodiment. As in the first embodiment, also in the present embodiment, the air conditioner control device 12 performs the control processing of FIGS. 16A and 16B only when the occupant operation on the cancel switch 124 is permitted. The control processing of FIG. 16B is executed. The control processing of FIGS. 16A and 16B is periodically and repeatedly executed.

FIGS. 16A and 16B are flowcharts corresponding to FIG. 6 of the first embodiment. In the flowcharts of FIGS. 16A and 16B, steps having the same contents as those in FIG. 6 are denoted by the same reference numerals, and description thereof will be omitted.

In the flowcharts of FIGS. 16A and 16B, if it is determined in step S041 that the ignition switch 125 is off, the process proceeds to step S053. On the other hand, when it is determined that the ignition switch 125 is not off, the process proceeds to step S171.

In step S053, the air conditioner control device 12 acquires information indicated by an input signal input from the on-vehicle wireless device 89. As described above, the acquired information includes information indicating whether or not the portable device 891 has approached the vehicle 80 and has entered a predetermined area Ax (see FIG. 15) around the vehicle.

エ ア コ ン Then, the air conditioner control device 12 determines whether or not the portable device 891 has approached the vehicle 80 and has entered a predetermined area Ax around the vehicle.

If it is determined in step S053 that the portable device 891 has approached the vehicle 80 and has entered the predetermined area Ax around the vehicle, the process proceeds to step S071. On the other hand, when it is determined that the portable device 891 has approached the vehicle 80 and has not entered the predetermined area Ax around the vehicle, the process proceeds to step S171.

As shown in FIGS. 16A and 16B, from step S071, the process proceeds to step S111, step S121, and step S161, and after step S161, the process proceeds to step S173. In addition, since the determination regarding the elapsed time from the start of the operation of the blower 14 is performed in step S193 described later, the measurement of the elapsed time with the start of the operation of the blower 14 set to zero is performed in step S161 of the present embodiment. .

Also, as shown in FIGS. 16A and 16B, in the present embodiment, before it is determined whether or not the door openings 82 and 84 are opening the doors in steps S173 and S183 described later, the blower 14 is activated. Therefore, even when the door openings 82 and 84 are closed, air is blown out from the D-seat side and P-seat side side face outlets 911a and 912a.

In step S173, the air conditioner control device 12 performs the same processing as in step S051 in FIG. That is, the air conditioner control device 12 recognizes the open / closed state of the D seat side door 86 shown in FIG. 1 based on the signal from the D seat side door open / close sensor 121. Then, the air conditioner control device 12 determines whether or not the D-seat-side door opening 82 is opening the door.

If it is determined in step S173 that the D-seat-side door opening 82 is being opened, the process proceeds to step S203. On the other hand, when it is determined that the D-seat-side door opening 82 is not opening the door, the process proceeds to step S183.

In step S183, the air conditioner control device 12 performs the same processing as in step S061 in FIG. That is, the air conditioner control device 12 recognizes the open / closed state of the P seat side door 88 shown in FIG. 1 based on the signal from the P seat side door open / close sensor 122. Then, the air conditioner control device 12 determines whether or not the P-seat-side door opening 84 is opening the door.

If it is determined in step S183 that the P-seat-side door opening 84 is being opened, the process proceeds to step S203. On the other hand, when it is determined that the P-seat-side door opening 84 is not opening the door, the process proceeds to step S193.

In step S193, the air conditioner control device 12 determines whether or not a predetermined time TMa has elapsed since the start of the operation of the blower 14 in step S161.

If it is determined in step S193 that the predetermined time TMa has elapsed since the start of the operation of the blower 14, the process proceeds to step S171. More specifically, step S193 is executed when the determinations in steps S173 and S183 are both “NO”. Therefore, when it is determined in step S193 that the predetermined time TMa has elapsed from the start of the operation of the blower 14 with the doors 86 and 88 closing both the D-seat side and the P-seat side door openings 82 and 84. Then, the process proceeds to step S171.

On the other hand, if it is determined in step S193 that the predetermined time TMa has not elapsed from the start of the operation of the blower 14, the process proceeds to step S161.

に お い て In step S203, the air conditioner control device 12 continues the operation of the blower 14 started in step S161. After step S203, the process proceeds to step S213.

Here, if step S203 is executed when the D-seat-side door opening 82 is opening the door, it can be said that the air conditioner control device 12 performs the following. That is, the air conditioner control device 12 controls the D-seat-side wind direction changing device 92 when blowing air from the D-seat-side side face outlet 911a while the D-seat-side door opening 82 is open. Then, it can be said that the air conditioner control device 12 directs the blowout direction of the D-seat side face outlet 911a to the outside of the vehicle compartment by controlling the D-seat side wind direction changing device 92.

{Circle around (2)} If step S203 is executed when the P-seat-side door opening 84 is being opened, it can be said that the air conditioner control device 12 performs the following. That is, the air conditioner control device 12 controls the P-seat-side wind direction changing device 93 when blowing air from the P-seat-side side face outlet 912a while the P-seat-side door opening 84 is open. Then, it can be said that the air conditioner control device 12 controls the P-seat side wind direction changing device 93 to direct the blowout direction of the P-seat side face face outlet 912a to the outside of the vehicle compartment. In this embodiment, as in the first embodiment, the D-seat-side side face outlet 911a and the P-seat-side side face outlet 912a correspond to the predetermined outlet Ps.

に お い て In step S213, the air conditioner control device 12 acquires a signal from the D-seat-side door opening / closing sensor 121. Thereby, the air conditioner control device 12 recognizes the open / closed state of the D-seat side door 86 shown in FIG.

エ ア コ ン Then, the air conditioner control device 12 determines whether or not the D-seat-side door opening 82 is closed by the D-seat-side door 86.

If it is determined in step S213 that the D-seat-side door opening 82 is closed, the process proceeds to step S223. On the other hand, if it is determined that the D-seat-side door opening 82 is not yet closed, that is, if it is determined that the D-seat-side door opening 82 is still opening the door, the process proceeds to step S203. .

In step S223, the air conditioner control device 12 acquires a signal from the P-seat-side door open / close sensor 122. Thereby, the air conditioner control device 12 recognizes the open / closed state of the P seat side door 88 shown in FIG.

エ ア コ ン Then, the air conditioner control device 12 determines whether or not the P-seat-side door opening 84 is closed by the P-seat-side door 88.

If it is determined in step S223 that the P-seat-side door opening 84 is closed, the process proceeds to step S171. On the other hand, when it is determined that the P-seat-side door opening 84 is not yet closed, that is, when it is determined that the P-seat-side door opening 84 is still opening the door, the process proceeds to step S203. .

エ ア コ ン In step S171 in FIG. 16B, the air conditioner control device 12 performs the same processing as in step S171 in FIG. That is, the air conditioner control device 12 stops the blower 14 that has been operating in step S161. After step S171, the process returns to step S011.

エ ア コ ン The air conditioner control device 12 of the present embodiment performs the control processing of FIGS. 16A and 16B as described above. As a result, the air conditioner control device 12 operates the blower 14 while the door of the D-seat side door opening 82 is open as shown in FIG. Through the D-seat side face outlet 911a.

In the control processing of FIGS. 16A and 16B, the air conditioner control device 12 activates the blower 14 while the door of the P-seat side door opening 84 is open, and sends the air flowing from the blower 14 to the P-seat side face. The air is blown from the P-seat side face air outlet 912a through the duct 40.

When the portable device 891 approaches the vehicle 80 and enters the predetermined area Ax around the vehicle, the air conditioner control device 12 controls the blower 14 even if the door openings 82 and 84 are not opened by the doors 86 and 88. Activate. Then, the air conditioner control device 12 blows out the air flowing from the blower 14 from a predetermined outlet Ps (see FIG. 9).

Therefore, the door openings 82, 84 are moved from the vehicle interior side to the vehicle exterior side with respect to the opened door openings 82, 84 without delay from the moment when any one of the door openings 82, 84 is opened by the doors 86, 88. , 84 can be blown.

16A and 16B, step S193 is provided as described above. Thereby, the air conditioner control device 12 performs the following processing when the blower 14 is operated when the portable device 891 approaches the vehicle 80 and enters the predetermined area Ax. That is, in this case, the air conditioner control device 12 stops the blower 14 when a predetermined time TMa has elapsed from the start of the operation of the blower 14 with the door openings 82 and 84 closed by the doors 86 and 88. . Therefore, it is possible to prevent the operation of the blower 14 from being unnecessarily continued.

Except as described above, this embodiment is the same as the first embodiment. Further, in the present embodiment, the effects obtained from the configuration common to the above-described first embodiment can be obtained in the same manner as the first embodiment.

Note that this embodiment is a modification based on the first embodiment, but it is also possible to combine this embodiment with the above-described second embodiment.

(Fourth embodiment)
Next, a fourth embodiment will be described. In the present embodiment, points different from the first embodiment will be mainly described.

In the present embodiment, the air conditioner control device 12 also executes the control process of FIG. 17 in parallel with the control process of FIG. This embodiment is different from the first embodiment in this point.

FIG. 17 is a flowchart illustrating a control process executed by the air conditioner control device 12 of the present embodiment. The control process of FIG. 17 is executed in parallel with the control process of FIG. 6, and the control process of FIG. 6 and the control process of FIG. 17 are each repeatedly executed periodically.

As in the first embodiment, also in the present embodiment, the air conditioner control device 12 performs the control process of FIG. 6 only when the execution of the control process of FIG. Execute the process. Since the control process of FIG. 17 is performed on the assumption that the control process of FIG. 6 is performed, the air conditioner control device 12 performs the control process of FIG. No control processing is performed.

{Circle around (1)} First, the air conditioner control device 12 determines whether or not the engine of the vehicle 80 has been stopped by switching the ignition switch 125 in step S014 in FIG. In short, the air conditioner control device 12 determines whether or not the engine of the vehicle 80 has been switched from the on state where the engine is operating to the off state where the engine is stopped by switching the ignition switch 125. In other words, the air conditioner control device 12 determines whether or not the occupant's operation on the ignition switch 125, which is a vehicle start switch, has switched the vehicle 80 from a running state to a non-running state. For example, when the ignition switch 125 is switched from on to off while the engine of the vehicle 80 is operating, the engine switches from on to off.

エ ン ジ ン Note that the engine off state determined in step S014 does not include temporary engine stoppage due to idling stop or the like. This is because such a temporary stop of the engine is not an engine stop caused by switching of the ignition switch 125.

If the off state of the engine of the vehicle 80 has already been continued, it is not determined that the engine of the vehicle 80 has been switched from the on state to the off state by switching the ignition switch 125.

If it is determined in step S014 that the engine of the vehicle 80 has been switched from the on state to the off state by switching the ignition switch 125, the process proceeds to step S024.

On the other hand, if it is determined in step S014 that the engine of the vehicle 80 has not been switched from the ON state to the OFF state by switching the ignition switch 125, the process returns to the beginning of the flowchart. That is, the air conditioner control device 12 performs the determination in step S014 again.

In step S024, the air conditioner control device 12 sets the air conditioner unit 11 to a predetermined standby mode. Putting the air conditioner unit 11 into the standby mode means setting the air conditioner unit 11 into the above-described intrusion prevention mode, closing the center face blowout openings 191c and 191d (see FIG. 4), and closing the side face blowout openings 191a. 191b is released.

In other words, in this case, the air conditioner control device 12 controls the inside / outside air switching door 16 to change the suction mode of the air conditioner unit 11 to the outside air mode. Further, the air conditioner control device 12 operates the air mix door 26, and sets the door position of the air mix door 26 to the MAXCOOL position. In addition, the air conditioner control device 12 operates the center face door 32 and closes the center face blow-out openings 191c and 191d by the center face door 32. Further, the air conditioner control device 12 activates the defroster door 33, and closes the defroster blowing opening with the defroster door 33. Further, the air conditioner control device 12 activates the foot door 34 and closes the foot outlet opening with the foot door 34. Further, the air conditioner control device 12 operates the side face doors 28 and 30, and opens the side face opening 191a and 191b on the side of the D seat and the side of the P seat by the side face doors 28 and 30.

完了 After the completion of the process in step S024, all of the blowout openings except for the side face blowout openings 191a and 191b on the D and P seat sides are closed.

Here, the function of the inside / outside air switching door 16, the air mixing door 26, the center face door 32, the defroster door 33, and the foot door 34, respectively, changes the air conditioning ventilation path which is the ventilation path of the air flowing through the air conditioning unit 11. Route change device. That is, the air conditioner unit 11 includes a plurality of route change devices.

For example, the air conditioner ventilation path changed by the inside / outside air switching door 16 as the path change device is a ventilation path on the upstream side of the air flow to the blower 14 in the air conditioner unit 11. The air-conditioning ventilation path changed by the air mix door 26 as the path change device is a ventilation path from the upstream side to the downstream side of the air flow across the air mix door 26 shown in FIG. The air conditioner ventilation path changed by the center face door 32 as the path changing device is a ventilation path heading to the center face blowout openings 191c and 191d in the air conditioner unit 11. The air conditioner ventilation path changed by the defroster door 33 as the path changing device is a ventilation path heading toward the defroster outlet opening in the air conditioner unit 11. The air conditioner ventilation path changed by the foot door 34 as the path changing device is a ventilation path heading toward the foot outlet in the air conditioner unit 11.

In the above-described standby mode, the air conditioner ventilation path established by each of the path change devices is controlled by the air conditioner controller 12 from the predetermined outlet Ps during the door opening of the door openings 82 and 84 in the control process of FIG. This is a state established when air is blown out. For example, when the air conditioner unit 11 is in the standby mode, the state of the air conditioner ventilation path established by the air mix door 26 is a state established by the air conditioner controller 12 in steps S071 and S131 of FIG. In this embodiment, as in the first embodiment, the D-seat-side side face outlet 911a and the P-seat-side side face outlet 912a correspond to the predetermined outlet Ps.

Therefore, it can be said that the air conditioner control device 12 performs the following as a result of the control processing of FIG. That is, when the engine of the vehicle 80 is stopped, it can be said that the air conditioner control device 12 operates each of the route change devices so that the target state of the air conditioner ventilation route is established in advance regardless of whether the doors 86 and 88 are opened or closed. . The target state of the air conditioner ventilation path is the state of the air conditioner ventilation path established when the air conditioner controller 12 blows air from the predetermined outlet Ps while one or both of the door openings 82 and 84 are open. It is.

Except as described above, this embodiment is the same as the first embodiment. Further, in the present embodiment, the effects obtained from the configuration common to the above-described first embodiment can be obtained in the same manner as the first embodiment.

Further, according to the present embodiment, when the engine of the vehicle 80 is stopped, the air conditioner control device 12 sets the target condition of the air conditioner ventilation path in advance regardless of whether the doors 86 and 88 are open or closed. Activate the change device. That is, when the vehicle 80 is switched from a state in which the vehicle can travel to a state in which the vehicle cannot travel by the occupant operation on the ignition switch 125, the air conditioner control device 12 sets the target state in advance regardless of the opening and closing of the doors 86 and 88. Each route changing device is operated so as to be established. The target state of the air conditioner ventilation path is the state of the air conditioner ventilation path established when the air conditioner controller 12 blows air from the predetermined outlet Ps while one or both of the door openings 82 and 84 are open. It is.

Therefore, immediately after any one of the door openings 82, 84 is opened by the doors 86, 88, the door openings 82, 84 are moved from the vehicle interior side to the vehicle exterior side with respect to the opened door openings 82, 84. It is possible to blow out air so as to pass through.

Note that this embodiment is a modification based on the first embodiment, but it is also possible to combine this embodiment with the above-described second embodiment or the third embodiment.

That is, the inlet ends 411, 421 of the two center face ducts 41, 42 are connected to the two center face outlet openings 191c, 191d via the center face opening / closing device 13, respectively.

Then, the center face opening / closing device 13 opens and closes a ventilation path between the entrance ends 411, 421 of the center face ducts 41, 42 and the center face outlet openings 191c, 191d. That is, the center face opening / closing device 13 opens and closes the two center face blowing openings 191c and 191d outside the air conditioner unit 11.

For example, in the control processing of FIG. 13, the center face opening openings 191c and 191d are closed by the center face opening / closing device 13 in steps S091, S111, and S141.

Except as described above, this embodiment is the same as the second embodiment. Then, in the present embodiment, the effects achieved by the configuration common to the above-described second embodiment can be obtained in the same manner as in the second embodiment.

According to the present embodiment, the center face opening / closing device 13 is attached to the air conditioner unit 11, and opens and closes the center face blowing openings 191c and 191d. Therefore, even when the air conditioner unit 11 is not provided with the center face door 32, the air volume to be blown out from the predetermined outlet Ps while the doors of the D-seat side door openings 82 and 84 are open can be obtained. It is possible to obtain as much as. In the present embodiment, similarly to the second embodiment, the D-seat-side outward air outlet 915a and the P-seat-side outward air outlet 916a correspond to the above-described predetermined air outlet Ps.

(Other embodiments)
(1) In each of the above-described embodiments, for example, as shown in FIG. 1, one side in the vehicle left-right direction DR2 is the vehicle right side, and the other side in the vehicle left-right direction DR2 is the vehicle left side, but this is an example. . Conversely, one side in the vehicle left-right direction DR2 may be the vehicle left side, and the other side in the vehicle left-right direction DR2 may be the vehicle right side.

(2) In the above-described first embodiment, as shown in FIG. 3, the vehicle 80 has the cancel switch 124, but the cancel switch 124 is not an essential component. If there is no cancel switch 124, for example, the air conditioner control device 12 executes the control process of FIG. 6 assuming that the execution of the control process of FIG. 6 is permitted. This is the same for the control processing shown in the flowchart corresponding to FIG. 6 in the second and subsequent embodiments.

(3) In the above-described first embodiment, steps S021, S031, and S041 are provided in the flowchart illustrated in FIG. 6, but these steps are not essential.

May be activated.

(12) In the above-described first embodiment, as shown in FIGS. 4 and 9, the air conditioner control device 12 is configured to open the D-seat side and the P-seat side door openings 82 and 84 while one or both doors are open. Then, the air blown by the blower 14 is blown out from the predetermined outlet Ps. The D-side seat side face outlet 911a and the P-side seat side face outlet 912a correspond to the predetermined outlet Ps. However, this is only an example. 20 to 22, the outlets other than the side face outlets 911a and 912a may correspond to the predetermined outlet Ps.

FIG. 20 shows a configuration in which the center face outlets 913a and 914a correspond to the predetermined outlets Ps in addition to the side face outlets 911a and 912a. In this case, as shown in FIG. 20, the two center outlets 913 and 914 are provided with wind direction change devices 961 and 962, respectively, and the wind direction change devices 961 and 962 serve to blow air from the center face outlets 913a and 914a.
