  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  The power distribution support apparatus according to an embodiment of the present invention is applied to an in-vehicle system. This in-vehicle system is configured as shown in FIG.

  In FIG. 1, this in-vehicle system has a processing unit 11 constituted by a computer unit (for example, CPU). Connected to the processing unit 11 are an AV unit 17 capable of reproducing various sound sources and video sources (for example, CD, DVD, etc.) and a navigation unit 18 capable of guiding a route to a set destination. . The processing unit 11 is connected to an output circuit 15 connected to a speaker 16 capable of outputting sound. As a result, audio signals related to processing by the AV unit 17 and the navigation unit 18 are output from the speaker 16 via the output circuit 15. The processing unit 11 is connected to an output circuit 15 connected to a speaker 16 capable of outputting sound. As a result, audio signals related to processing by the AV unit 17 and the navigation unit 18 are output from the speaker 16 via the output circuit 15.

  The processing unit 11 includes a storage unit 14 (for example, a hard disk) in which various pieces of information such as music information and map information used for processing by the AV unit 17 and the navigation unit 18 are stored, and various types of LCDs. A display unit 13 that displays a video or the like associated with the process is connected, and the display unit 13 is formed with an operation unit 12 capable of inputting instructions necessary for various processes formed in a touch panel format.

  In addition, a power amount detection circuit 19 that detects the amount of power stored in the battery 50 is connected to the processing unit 11. As a result, the processing unit 11 acquires the amount of power detected by the power amount detection circuit 19. In addition, an air conditioner control circuit 21 that performs electronic control of the air conditioner 30 is connected to the processing unit 11. The air conditioner control circuit 21 receives a signal from the processing unit 11 and controls the air conditioner 30 based on the received signal. Further, the air conditioner control circuit 21 measures the power consumption of the air conditioner 30. As a result, the processing unit 11 acquires the power consumption of the air conditioner 30 and can control the air conditioner 30 based on the power consumption, for example. The processing unit 11 is connected to an RSE control circuit 22 that performs electronic control of the RSE 40 (rear seat entertainment). The RSE control circuit 22 receives a signal from the processing unit 11 and controls the RSE 40 based on the signal. As with the air conditioner control circuit 21, the RSE control circuit 22 can measure the power consumption of the RSE 40, and the processing unit 11 acquires the power consumption of the RSE 40.

  The AV unit 17 (audio) described above incorporates an AV control circuit (not shown). Like the air conditioner control circuit 21 and the RSE control circuit 22, the AV unit 17 is controlled based on a signal from the processing unit 11. While controlling, it is possible to measure the power consumption of the AV unit 17.

  Further, the RSE 40 (rear seat entertainment) including the processing unit 11, the AV unit 17 (audio), the air conditioner 30, and a display unit (not shown) provided in the vicinity of the rear seat of the vehicle is stored in the battery 50 described above. It works by using energy. A motor (not shown) for driving an electric vehicle on which the in-vehicle system is mounted is connected to the battery 50 via a control circuit (not shown), and the battery 50 is driven by electric power supplied from the battery 50. .

  As described above, in the in-vehicle system to which the vehicle power consumption management device is applied, the amount of power stored in the battery 50 is assigned to each predetermined amount for each running of the electric vehicle and each operation of the plurality of in-vehicle devices (audio, air conditioner 30, RSE40). It is used in the state allocated by. In this way, the processing unit 11 can display the allocated power amount information representing each of the electric energy allocated for the running of the electric vehicle and the operations of the plurality of in-vehicle devices on the display unit 13, for example, The power amount is distributed and the distributed power amount is displayed in the procedure as shown in FIG. Hereinafter, it will be described in detail with reference to FIG.

  In FIG. 2, the processing unit 11 travels to the destination of the electric vehicle set by the navigation unit 18 when the destination is set by operating the operation unit 12 formed on the display unit 13. A route is acquired (S11: travel route acquisition means), and the amount of power stored in the battery 50 is acquired (S12: storage amount acquisition means). Then, the processing unit 11 allocates the electric energy acquired in step S12 to the traveling of the electric vehicle traveling route and the operations of a plurality of in-vehicle devices such as the audio, the air conditioner 30, and the RSE 40 in a predetermined distribution ( S13: Power allocation means). In this way, the allocation indicating the amount of power allocated to the running of the electric vehicle allocated by the processing unit 11 and the amount of power allocated to the operation of the plurality of in-vehicle devices (audio, air conditioner 30, RSE40). The power information is displayed on the display unit 13 as a power allocation adjustment screen as shown in FIG. 4 (S14: display control means).

  In FIG. 4, the display unit 13 displays the amount of power stored in the battery 50 (300 kW) and the amount of power allocated for traveling to the destination (Goal) of the electric vehicle allocated with a predetermined distribution ( AKW), the amount of power allocated to the operation of the air conditioner 30 (BKW), the amount of power allocated to the operation of audio (CKW), and the amount of power allocated to the operation of RSE 40 (DKW) are displayed. In this power allocation adjustment screen, the amount of power stored in the battery 50 is preferentially allocated to travel to the destination of the electric vehicle over the operation of the air conditioner 30, audio, and RSE 40, and the remaining amount of power is allocated to the air conditioner. 30 and assigned for audio activity. In addition, since electric energy is preferentially allocated to traveling to the destination of the electric vehicle, the electric energy (DKW) allocated to the operation of the RSE 40 is 0 KW.

  Returning to the flowchart of FIG. 2, the processing unit 11 displays the power allocation adjustment screen on the display unit 13, and the amount of power (AKW) allocated to the travel to the destination of the electric vehicle can reach the destination. It is determined whether the amount of power is present (S15). At this time, since the electric energy (AKW) allocated for traveling to the destination of the electric vehicle has reached the electric energy of 200 KW required to reach the destination (YES in S15), the processing unit 11 While monitoring whether or not the power allocation adjustment by the occupant (user) (details will be described later) is completed (S19), the power allocation adjustment screen is continuously displayed on the display unit 13 (S14).

  As described above, an occupant (user) can operate the power allocation adjustment screen displayed on the display unit 13. For example, as shown in FIG. 4, the amount of power (AKW) allocated to the travel of the electric vehicle represented by the allocated power information displayed on the display unit 13, and the power distributed to the operations of the air conditioner 30, the audio, and the RSE 40 When the occupant (user) operates the amount (BKW, CKW, DKW), the amount of electric power can be increased or decreased. Thus, the processing unit 11 can update the allocated power amount information displayed on the display unit 13 according to the power amount distributed according to the user's operation (S14: first user interface means). ). Moreover, even if the electric energy (BKW, CKW, DKW) allocated to the operations of the air conditioner 30, the audio, and the RSE 40 is changed by the user's operation, the electric energy (AKW) allocated to the running of the electric vehicle is It is set not to change. In addition, even if any of the electric energy (BKW, CKW, DKW) allocated to the operations of the air conditioner 30, the audio, and the RSE 40 is changed by the user's operation, the change (increase / decrease of the electric energy) Accordingly, any one of the electric energy (BKW, CKW, DKW) allocated to the operation of the air conditioner 30, the audio, and the RSE 40 that has not been changed is set not to be automatically changed.

  For example, when the electric energy (BKW) allocated to the operation of the air conditioner 30 is reduced, the surplus electric energy produced by the reduction can be distributed to the operation of the RSE 40. The amount of power allocated to the operation of the air conditioner, as well as the amount of power allocated to the operation of the audio (CKW) and the amount of power allocated to the operation of the RSE 40 (DKW) It does not automatically increase / decrease in accordance with the decrease in (BKW), and the occupant himself / herself must allocate the amount of electric power (CKW, DKW). Further, the amount of power allocated in this way is updated by the processing unit 11 each time.

  In this way, each time the power amount allocation is updated, the processing unit 11 repeats the processes of steps S15 to S19 described above. Then, when it is confirmed that the power allocation adjustment by the occupant (user) is completed and the completion button displayed on the power allocation adjustment screen displayed on the display unit 13 is pressed (YES in S19), the processing unit 11 Then, the power monitoring process (S30) is performed. Further, the processing unit 11 performs power monitoring processing (details will be described later) and drives the navigation unit 18 to start route guidance to the destination. At this time, for example, a screen as shown in FIG. 5 is displayed on the display unit 13, and in addition to the destination, the travel route to the destination, the amount of power allocated to the travel to the destination of the electric vehicle ( 200 kW) and the amount of electric power (BKW, CKW, DKW) allocated to the operation of a plurality of in-vehicle devices (air conditioner 30, audio, and RSE 40) are displayed together. As a result, the occupant can travel to the destination while grasping the amount of electric power allocated to each.

  Returning to the flowchart of FIG. 2, for example, a case will be described in which, in step S <b> 12, the charged amount (power amount) of the battery 50 acquired by the processing unit 11 is 200 kW.

  As described above, when the amount of electricity of the battery 50 is acquired (S12), the processing unit 11 uses the predetermined distribution of the acquired amount of power, travels along the travel route of the electric vehicle, and the audio, air conditioner 30, It allocates to operation | movement of several vehicle equipment, such as RSE40 (S13). At this time, if the amount of power necessary for the electric vehicle to travel on the travel route to the destination is equal to or greater than the amount of power (200 KW) stored in the battery 50, the processing unit 11 receives other in-vehicle equipment (air conditioner 30 , Audio and RSE 40) are not allocated power. In this manner, the electric energy allocated to the running of the electric vehicle allocated by the processing unit 11 and the electric energy indicating the electric energy allocated to the operation of the plurality of in-vehicle devices (audio, air conditioner 30 and RSE 40) are represented. The allocated power information is displayed on the display unit 13 as a power allocation adjustment screen as shown in FIG. 6 (S14).

  In FIG. 6, the display unit 13 displays the amount of power stored in the battery 50 (200 kW) and the amount of power allocated for traveling to the destination (Goal) of the electric vehicle allocated with a predetermined distribution ( AKW), the amount of power allocated to the operation of the air conditioner 30 (BKW), the amount of power allocated to the operation of audio (CKW), and the amount of power allocated to the operation of RSE 40 (DKW) are displayed. In this power allocation adjustment screen, since all the electric energy (200 KW) is allocated to the travel of the electric vehicle travel route, the electric energy (BKW, CKW) allocated to the operations of the air conditioner 30, the audio, and the RSE 40, respectively. , DKW) is 0 KW.

  Returning to the flowchart of FIG. 2, the processing unit 11 displays the power allocation adjustment screen on the display unit 13, and the amount of power (AKW) allocated to the travel to the destination of the electric vehicle can reach the destination. It is determined whether the amount of power is present (S15). At this time, since the electric energy (AKW) allocated for traveling to the destination of the electric vehicle has reached the electric energy of 200 KW required to reach the destination (YES in S15), the processing unit 11 While monitoring whether or not the power allocation adjustment by the occupant (user) (details will be described later) is completed (S19), the power allocation adjustment screen is continuously displayed on the display unit 13 (S14).

  In such a situation, when the occupant operates the power allocation adjustment screen displayed on the display unit 13, for example, as shown in FIG. For example, the electric energy (AKW) allocated to the running of the electric vehicle represented by the allocated electric power information displayed on the display unit 13 is reduced, and the surplus electric energy generated by the reduction is reduced in the air conditioner 30, the audio, and the RSE 40. By allocating power amounts for operation (BKW, CKW, DKW), the power amounts can be increased or decreased. In this way, the processing unit 11 can update the allocated power amount information displayed on the display unit 13 according to the amount of power distributed according to the operation of the occupant (S14).

  In addition, when any one of the electric energy (BKW, CKW, DKW) allocated to the operation of the air conditioner 30, the audio, and the RSE 40 is changed according to the operation of the occupant, the processing unit 11 changes the electric energy. The electric energy (AKW) allocated to the travel to the destination of the electric vehicle is changed so as to cancel out the above. Further, when the amount of electric power (AKW) allocated for traveling to the destination of the electric vehicle is changed according to the operation of the occupant, the processing unit 11 causes the air conditioner 30 to cancel the change in the amount of electric power (AKW). , Audio, and electric power (BKW, CKW, DKW) allocated to at least one of the operations of the RSE 40 are changed. As a specific example, when the electric energy (AKW) allocated to traveling to the destination of the electric vehicle is reduced by, for example, 20 KW according to the operation of the occupant, the RSE 40 and the other are set to cancel the 20 KW. The electric power of 20 KW is allocated to the operation of the in-vehicle devices (the air conditioner 30 and the audio). Further, the amount of power allocated in this way is updated by the processing unit 11 each time.

  In this way, each time the power amount allocation is updated, the processing unit 11 can reach the destination with the power amount (AKW) allocated to the travel to the destination of the electric vehicle in step S14. Is determined (S15). At this time, the display unit 13 displays destination reachability information indicating whether or not the electric vehicle can travel to the destination on the travel route with the electric energy (AKW) allocated to the travel of the electric vehicle. Specifically, by displaying AKW on the middle part of the travel route from START to GOAL displayed on the display unit 13, the amount of power allocated for traveling to the destination of the electric vehicle It is possible to let the occupant know that he can only travel about half the distance he needs to travel before reaching the ground. Thus, since the destination cannot be reached with the electric energy (AKW) allocated to the travel to the destination of the electric vehicle (NO in S15), the processing unit 11 should stop by charging the battery 50. It is determined whether or not the charging facility is set (S16).

  As shown in FIG. 7, since the charging facility is not set, the processing unit 11 uses a charging facility setting button (for guiding information related to the charging facility for charging the battery 50 in accordance with the operation of the passenger (user)). (Second interface) is displayed below the display unit 13 (S17). Then, the processing unit 11 monitors whether or not the charging facility setting button is operated by the occupant (user) (S18). When it is determined that the charging facility setting button has been operated by the passenger (user) (YES in S18), the processing unit 11 deletes the charging facility setting button displayed on the display unit 13 (S20). Then, the processing unit 11 searches for charging facilities in a range where the vehicle can travel from the travel route set by the navigation unit 18 based on the amount of power (AKW) allocated to the travel to the destination (S20). The charging facility setting screen is displayed on the display unit 13 as shown in FIG.

  In FIG. 8, in addition to the travel route to the destination, the display unit 13 includes the amount of power (100 kW) allocated to the travel to the destination of the electric vehicle and the vibration allocated to the travel and located on the travel route. The charging facilities A, B, and C that are located within a distance that can be traveled by the amount of electric power that is generated are displayed together. In these charging facilities A, B, and C, the distance from the current position and the amount of electric power required to reach the charging facility are displayed. Accordingly, the occupant (user) can select the charging facility to stop by visually recognizing the charging facility setting screen displayed on the display unit 13 and touching the selected charging facility (for example, charging facility A). it can.

  Returning to the flowchart of FIG. 3, the processing unit 11 determines whether or not a drop-in charging facility has been selected (S <b> 23). When the charging facility to be stopped by this is selected (NO in S23), the processing unit 11 returns to step S14 described above and repeats the processing from step S14 to S23. On the other hand, when the charging facility to be stopped is selected in step S23 (YES in S23), the processing unit 11 returns to step S14 as described above and allocates the power displayed on the display unit 13 as shown in FIG. The charging facility set display is additionally displayed on the adjustment screen (S24). Specifically, in order to charge the battery 50 of the electric vehicle by displaying “Charge POINT” on the part corresponding to the charging facility position on the travel route from START to GOAL displayed on the display unit 13. The passenger can be informed that the charging facility is selected.

  In addition, even after the charging facility is selected, if the allocation of the electric energy is updated, the processing unit 11 has already set the charging facility (YES in S16). Therefore, the above-described steps S15, S16, The process of S19 is repeated. Then, when it is confirmed that the power allocation adjustment by the occupant (user) is completed and the completion button displayed on the power allocation adjustment screen displayed on the display unit 13 is pressed (YES in S19), the processing unit 11 Then, the power monitoring process (S30) is performed. Further, the processing unit 11 performs power monitoring processing (details will be described later) and drives the navigation unit 18 to start route guidance to the destination. At this time, for example, the screen shown in FIG. 10 is displayed on the display unit 13. In addition to the destination, the travel route to the destination, charging facility information to be stopped (information on the charging facility A), The amount of electric power allocated to travel to the destination of the electric vehicle (100 KW) and the amount of electric power allocated to the operation of a plurality of in-vehicle devices (air conditioner 30, audio, and RSE 40) (BKW, CKW, DKW) are displayed together. It has become so. As a result, the occupant can travel to the destination while grasping the amount of electric power allocated to each.

  Even during the process as described above (steps S14 to S18, S20 to S24), if the power allocation completion button is pressed by the occupant (user) (YES in S19), all the processes are performed. The processing unit 11 performs power monitoring processing and starts route guidance by the navigation unit 18. For example, even if the amount of power (AKW) allocated for traveling to the destination of the electric vehicle is the amount of power that cannot reach the destination, there is a charging facility that can reach the passenger (user) It is possible to respond flexibly in cases where it is not necessary to search for a charging facility.

  Further, the above-described power monitoring process (S30: power consumption monitoring means) will be described in detail here. 11 and 12 are flowcharts showing the flow of power monitoring of the air conditioner 30, for example. Hereinafter, a description will be given with reference to FIGS. 11 and 12.

  In FIG. 11, the processing unit 11 acquires the allocated power amount (BKW) of the air conditioner 30 (S301). Then, the processing unit creates a standard power characteristic Qp to the destination based on the allocated power amount (BKW) (S302). Specifically, in the graph shown in FIG. 13, the horizontal axis is the distance (200 km) or time from START to GOAL, and the vertical axis is the integrated power amount (the amount of power consumed when using the air conditioner 30 is integrated ( KW). In this graph, the standard power characteristic Qp is indicated by a broken line Qp. When the power for operating the air conditioner 30 is used as indicated by the broken line, when the power reaches the destination (GOAL) in advance, This is the amount of power allocated (BKW).

  Returning to the flowchart of FIG. 11, the processing unit 11 monitors whether or not the air conditioner 30 is activated (S303). When the air conditioner 30 is activated (YES in S303), the processing unit 11 constantly monitors whether or not the own vehicle (electric vehicle) has arrived at the destination (S304). When the host vehicle has not arrived at the destination (YES in S304), the processing unit 11 acquires power consumption via the air conditioner control circuit 21 (S305). The power consumption of the air conditioner 30 acquired in this way is integrated with the power consumption of the air conditioner 30 acquired so far, and the integrated power consumption is calculated (S306). Further, the processing unit 11 acquires the travel distance or travel time (S307), and determines whether or not the integrated power amount exceeds the standard power consumption amount Qp (S308).

  For example, when the travel distance acquired in step S307 is P1 shown in FIG. 13, it is determined that the integrated power amount at the P1 point has not reached the standard power consumption amount Qp (NO in S308), and the processing unit 11 performs a timer reset (S309) and repeats the above-described steps S305 to S308. Further, these processes (steps S305 to S308) are repeatedly performed. For example, when the travel distance acquired in step S307 is P2 shown in FIG. 13, the integrated power amount at the point P2 is the standard power consumption amount Qp. (S308: YES), the processing unit 11 determines whether or not the timer is operating (S310). At this time, if it is determined that the timer is not operating (NO in S310), the processing unit 11 starts the timer (S311). This timer is a timer for measuring the time during which the integrated power amount exceeds the standard power consumption amount Qp.

  Then, the processing unit 11 determines whether or not a predetermined time (for example, 3 minutes) has elapsed since the timer was started (S312). As described above, since the process is immediately after the timer is started in step S311, since the predetermined time has not elapsed, the processing unit 11 proceeds to step S305, where the power consumption, the integrated power amount, and the travel distance are determined. Is acquired (S305 to S307). Then, the processing unit 11 determines whether or not the integrated power amount exceeds the standard power consumption amount Qp (S308). Thereby, when the travel distance acquired in step S307 is P3 shown in FIG. 13, the integrated power amount at the point P3 is determined as the standard power consumption amount Qp (YES in S308), and the processing unit 11 It is determined whether or not the timer is operating (S310). At this time, if it is determined that the timer is operating (YES in S310), it is determined again whether a predetermined time (for example, 3 minutes) has elapsed since the timer was started (S312).

  Accordingly, if it is determined that a predetermined time has elapsed since the timer was started (YES in S312), the processing unit 11 issues an alarm (power consumption monitoring information) (S313). Then, after issuing an alarm, the processing unit 11 resets the timer, and proceeds to step S304. Then, as described above, the processing unit 11 continues these processes until the destination is reached. When it is determined that the destination has been reached (YES in S304), the power monitoring process for the air conditioner 30 is terminated.

  It should be noted that the alarm issued in step S313 described above is successively integrated as shown in FIG. 14A and FIG. 14B so as to notify that the power consumption of the air conditioner 30 exceeds the standard power consumption Qp. May be displayed on the display unit 13. Further, the integrated power amount may be displayed on the display unit 13 only when the power consumption amount of the air conditioner 30 exceeds the standard power consumption amount Qp without sequentially displaying the integrated power amount on the display unit 13. . Further, the fact that the power consumption of the air conditioner 30 has been exceeded may be output as an audio from the speaker 16.

  Further, although the power monitoring process in the air conditioner 30 has been described, of course, the same processing is performed by the processing unit 11 in the audio and RSE 40 as well.
