Referring to fig. 1 to 3, a vehicle-mounted air conditioning system according to an embodiment of the present invention includes: an air conditioner assembly, wherein the air conditioner assembly comprises an outer circulation damper 1 and an inner circulation damper 2 provided on an air conditioning box 100, and an exhaust blower 3 and an intake blower 4 arranged inside the air conditioning box 100, wherein the exhaust blower 3 is arranged corresponding to the outer circulation damper 1 to exhaust air to the outside of the vehicle, and the intake blower 4 is arranged corresponding to the inner circulation damper 2 to blow air to the inside of the vehicle; and a control device 200 electrically connected to the exhaust blower 3 and the suction blower 4, for controlling the operation 4 of the exhaust blower 3 and the suction blower.
The air conditioner assembly further includes conventional components such as a compressor, an evaporator, a warm air radiator, and an operating mechanism, and their respective functions and arrangements are well known in the art and can be understood with reference to the prior art, so that detailed description thereof is omitted here. In fig. 2 and 3, an Evaporator (EVP) is shown to illustrate a gas flow in the air intake and exhaust functions of the vehicle air conditioning system according to the present invention.
Referring to fig. 2 and 3, for example, the exhaust blower 3 and the intake blower 4 may be both of a centrifugal type, and the intake blower 4 has a function consistent with that of a conventional blower, as shown in fig. 2, and blows air to the interior of the vehicle (mainly a cab) through an air duct and an air outlet, and the corresponding circulating air door includes an external circulation and an internal circulation; the exhaust blower 3 is opposite to the intake blower 4, and as shown in fig. 3, blows out the air flow from the inside of the vehicle to the outside of the vehicle to perform the exhaust function, and the corresponding circulation damper is an outer circulation.
Therefore, compared with the prior art, the vehicle-mounted air conditioning system provided by the embodiment of the invention is provided with the two blowers, wherein one blower is used for sucking air, and the other blower is used for exhausting air, so that the air exhaust in a vehicle can be realized in time under some conditions, the temperature and the quality of the air in the vehicle can be changed rapidly, and the air conditioning efficiency is improved. In addition, the vehicle-mounted air conditioning system provided by the embodiment of the invention only needs to add an exhaust blower on the basis of the existing air conditioner, and structures such as a shutter, a protective net and a sealing ring are not needed to be added, so that the structural change is small, and the implementation is easy. In addition, the exhaust blower is positioned in the air conditioner assembly, and cannot be influenced by factors such as rain and the like, and the sealing performance of the vehicle cannot be influenced.
In addition, the arrangement of the double blowers realizes bidirectional air volume adjustment, so that the control device 200 can be used for further realizing the in-vehicle air conditioning method aiming at different conditions. Four examples of conditioning air in a vehicle are described in detail below.
First, first example
Fig. 4 is a flowchart illustrating an in-vehicle air conditioning method according to a first example of the embodiment of the present invention. As shown in fig. 4, the in-vehicle air conditioning method is applied to the control device 200, and may include the steps of:
and step S410, receiving a control instruction input by a user through the vehicle-mounted display.
In this example, the control device 200 may be configured as an in-vehicle display, and the in-vehicle display may be configured to send a control instruction to the intake blower and/or the exhaust blower in response to a touch screen operation and/or a voice operation by a user. For example, the vehicle-mounted display may be a HUT, which supports a multimedia function, a touch screen operation function, a voice command function, and the like. Taking a touch screen operation function as an example, the vehicle-mounted display can add an exhaust function icon on a screen, and when the icon is manually touched and lightened, the exhaust function of the vehicle-mounted air conditioning system can be activated; in addition, an icon for adjusting the gear position and the air displacement of the blower can be further configured together with the icon. It will be appreciated by those skilled in the art that the icons herein may also be illuminated other than through a touch screen, but rather associated with respective physical keys for illumination by user manipulation of the keys.
In this first example, the control command includes information indicating to turn on or off a preset exhaust function. It should be noted that the exhaust function according to the embodiment of the present invention is not related to only the exhaust blower, but relates to coordinated control of a plurality of components of the vehicle air conditioning system to realize an exhaust function that is adapted to various demands of a user under various conditions.
And step S420, executing exhaust control when the control instruction indicates that the exhaust function is started.
For example, when the vehicle air conditioning system is in an activated state, a conventional blower that is an air suction blower is in an operating state. In order to eliminate the peculiar smell in the vehicle or reduce the concentration of VOC gas, the exhaust function can be turned on/off through an exhaust icon on a multimedia display screen of the vehicle-mounted display so as to execute air exhaust control.
Preferably, in this step S420, the performing of the exhaust control may include the operations of:
A1) turning off the suction blower;
A2) turning on the exhaust blower;
A3) setting the internal circulation air door and the external circulation air door to be in an external circulation state;
A4) controlling the exhaust blower to keep the air volume unchanged; and
A5) and controlling the air-conditioning blowing mode of the vehicle-mounted air-conditioning system to be a non-blowing mode.
For the operation of item a5), the air-conditioning blowing mode includes a face blowing mode, a foot blowing mode, a "face blowing + foot blowing" mode, and the like, and each mode corresponds to its air outlet, if all air outlets are completely closed, it will cause the subsequent air suction difficulty, so only the air-conditioning blowing mode is set as the non-face blowing mode.
More preferably, the driver can turn off the exhaust function through the exhaust icon on the multimedia display screen according to the actual situation in the vehicle. For example, when the exhaust function is turned off, the following exhaust-off control may be performed in correspondence to the above five operations:
B1) turning off the exhaust blower;
B2) turning on the suction blower;
B3) setting the inner circulation air door and the outer circulation air door to return to the state before the exhaust function is opened;
B4) controlling the air suction blower to keep the air volume unchanged; and
B5) and controlling the air-conditioning blowing mode of the vehicle-mounted air-conditioning system to return to the state before the exhaust function is started.
Accordingly, in this first example, the intake and exhaust of air within the vehicle may be manually controlled via the in-vehicle display such that the temperature and quality of the air within the vehicle meets the needs of the user within the vehicle.
It should be noted that the execution sequence between the operations a1) -a5) and B1) -B5) can be arbitrarily adjusted, and the embodiment of the present invention is not limited thereto.
Second and third examples
Fig. 5 is a flowchart illustrating an in-vehicle air conditioning method according to a second example of the embodiment of the present invention. As shown in fig. 5, the in-vehicle air conditioning method is applied to the control device 200, and may include the steps of:
and step S510, receiving air conditioner expectation information sent by the mobile terminal through the background server.
In this second example, the control device 200 may be an in-vehicle terminal configured to be able to transmit a control instruction to the intake blower and/or the exhaust blower in response to air-conditioning desired information received from a mobile terminal. Preferably, the vehicle-mounted terminal may be a vehicle-mounted TBOX (Telematics BOX), the background server 100 may be a TSP (Telematics Service Provider) background, and the mobile terminal may be a smartphone. Like the multimedia display screen, the smart phone can also set an exhaust icon on the corresponding APP interface for the user to select whether to activate the exhaust function.
Accordingly, for this step S510, the mobile phone may send the air-conditioning expected information to the vehicle TBOX through the TSP backend, and the vehicle TBOX receives the air-conditioning expected information, and wakes up the entire vehicle network to perform air-conditioning control.
The air conditioning desired information refers to relevant air conditioning parameters desired by a user, such as desired vehicle interior temperature and VOC gas concentration, desired damper cycle state, air conditioning blowing mode, and other various air conditioning states and durations corresponding to the various air conditioning states, and the like, such as exhaust duration.
And step S520, responding to the air conditioning expectation information, controlling the air suction blower and the air exhaust blower to operate so that the air state in the vehicle meets the requirement of the air conditioning expectation information.
Note that, this step S520 is mainly intended to realize vehicle exhaust. In practice, for the example that the vehicle-mounted TBOX receives the air-conditioning expectation information, before proceeding to step S520, the method may include: the vehicle-mounted TBOX sends a power mode command to the PEPS (Passive Entry & Passive Start, keyless Entry and keyless Start system), switches the power mode to an ON gear, and sends an Engine Start command (for an ICE (internal Combustion Engine) vehicle type) or a high voltage command (BEV (Battery electric vehicle) vehicle type); then, the onboard TBOX transmits air conditioning desire information set by the user to an AC (air conditioning system on behalf of the onboard air conditioning system).
Further, in this step S520, the details of the implementation of controlling the operations of the intake blower and the exhaust blower may refer to steps a1) -a5) and steps B1) -B5 in the first example, but the air volume setting may be considered to adjust the air volume so that the air state in the vehicle meets the requirements of the air conditioning desired information, such as reaching the temperature or VOC concentration set by the user.
Step S530, acquiring real-time status information of the vehicle air conditioning system, and determining whether to turn off the suction blower and/or the exhaust blower based on a comparison of the real-time status information and the air conditioning expectation information.
Such as current temperature, VOC concentration, exhaust time, etc. For example, in step S530, the TBOX obtains the current exhaust time, and compares the current exhaust time with the expected exhaust time set in the expected information of the air conditioner, if the expected exhaust time is reached, the TSP background feeds back corresponding information to the mobile phone APP, and the mobile phone APP sends an air conditioner off and vehicle power-off instruction through the background TSP to turn off the exhaust function.
In this second example, besides the smart phone, the mobile terminal may be a tablet computer, a wearable smart device, or the like, and the mobile terminal may communicate with the vehicle-mounted TBOX in a long-range or short-range manner through a wired communication manner or a wireless communication manner, where the wireless communication manner may include wifi, bluetooth, or the like.
Accordingly, in this second example, the user can implement remote pre-control of the in-vehicle air conditioning system through the mobile terminal, and particularly, implement in-vehicle cooling and reduce in-vehicle odor and VOC gas content through remote pre-exhaust control. For example, a user intends to drive after half an hour, and can control the vehicle-mounted air conditioning system to exhaust, cool and the like in advance through the mobile phone, so that passengers can obtain better air experience when getting on the vehicle, and the physical and mental health of the passengers in the vehicle is guaranteed.
Third, third example
Fig. 6 is a flowchart illustrating an in-vehicle air conditioning method according to a third example of the embodiment of the present invention. As shown in fig. 6, the in-vehicle air conditioning method is applied to the control device 200, and may include the steps of:
and step S610, acquiring the temperature inside the vehicle and the temperature outside the vehicle.
Wherein, the vehicle-mounted air conditioning system may further include: and a temperature sensor (not shown) electrically connected to the control device 200, for detecting the temperature inside and outside the vehicle and transmitting the detected temperature to the control device 200. The control device 200 may be, for example, a vehicle ECU (electronic control unit) that may receive temperature information inside and outside the vehicle from a temperature sensor of the vehicle in real time through a vehicle CAN bus.
And S620, executing an exhaust function under the condition that the difference value between the temperature inside the vehicle and the temperature outside the vehicle is greater than or equal to a first target temperature difference value.
Preferably, the step S620 of performing the exhausting function may include the steps of:
C1) setting the internal circulation air door and the external circulation air door to be in an external circulation state;
C2) turning on the exhaust blower and turning off the suction blower;
C3) controlling an air-conditioning blowing mode of the vehicle-mounted air-conditioning system to be a face blowing and foot blowing mode;
C4) controlling the air volume of the exhaust blower to be maximum; and
C5) and controlling a compressor in the air conditioner assembly to be in a closed state.
Wherein setting the compressor to the off state is beneficial to avoiding energy waste.
And step S630, when the exhaust function exceeds the set time or the difference value between the temperature inside the vehicle and the temperature outside the vehicle is smaller than or equal to a second target temperature difference value, exiting the exhaust function.
Wherein the second target temperature difference is less than the first target temperature difference, both of which are normalized quantities, e.g., the second target temperature difference is 2 ℃ and the first target temperature difference is 10 ℃. The set time here is also a standard amount, and is, for example, 1 minute.
In a preferred embodiment, the third example is applied to a case where the in-vehicle air conditioning system is an automatic air conditioner, and when the in-vehicle air conditioning system is in AUTO (automatic) mode, the control device 200 automatically activates the air discharge function by comparing the difference between the inside and outside temperature and the target temperature.
