[0002] As the economic advantages of electric vehicles become increasingly apparent, electric vehicles have already achieved a high penetration rate, and this is accompanied by consumers' higher demand for electric vehicle functions.

[0003] When a vehicle has been parked for a long time in a relatively cold or hot environment, the temperature inside the cabin may not be suitable for the driver and passengers to enter. At this time, if you need to drive the vehicle, you need to enter the vehicle first, turn on the vehicle air conditioner, and wait outside the vehicle. Only when the temperature inside the cabin is suitable can you start driving the vehicle normally.

[0004] Although some existing electric vehicles can use apps to remotely control the vehicle status, the options for remote control of air conditioning are relatively limited and the efficiency of remote control of air conditioning is low. Summary of the Invention

[0052] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0053] As a representative of new energy vehicles, electric vehicles have the advantages of being economical, energy-saving, and environmentally friendly. As electric vehicles have attracted more and more attention from users due to their advantages such as low difficulty in obtaining a license plate, no restrictions on traffic, and low cost of use, the number of electric vehicles in use has also increased significantly. On this basis, users have begun to have more and broader demands for the functions of electric vehicles, such as wanting to use mobile phones to control the doors and windows or electrical appliances on electric vehicles. The embodiments of the present application combine cloud platforms, mobile phone apps, domain controllers, etc., and can remotely control the air quality and temperature inside the vehicle at any time, thereby improving the efficiency and precision of remote control of vehicle air conditioning and bringing an excellent driving experience.

[0054] The present application embodiment provides a remote control method for an electric vehicle air conditioner, such as Figure 1 As shown, the method includes steps S101, S102, S103 and S104, wherein:

[0055] In step S101 , upon receiving an air conditioning control request, the mobile terminal forwards the air conditioning control request to the in-vehicle remote communication device.

[0056] In step S102 , the vehicle-mounted remote communication device obtains the current state of the vehicle after receiving the air-conditioning control request.

[0057] In step S103 , when the vehicle-mounted remote communication device determines that the current state of the vehicle meets the preset state condition, it sends an air-conditioning control request to the vehicle controller.

[0058] In step S104, the vehicle controller controls the operation of the vehicle air conditioner according to the air conditioning control request, where the air conditioning control request includes at least one of a cooling request, a heating request, a defrosting request, a ventilation request, and a cabin cleaning request.

[0059] With the electric vehicle air conditioning remote control method provided in this application, when a mobile terminal receives an air conditioning control request, it indicates that the user has a need to remotely control the electric vehicle air conditioning using the mobile terminal. In this case, the air conditioning control request is forwarded to the vehicle-mounted remote communication device, which is responsible for communicating between the vehicle and devices outside the vehicle. When the vehicle-mounted remote communication device receives the air conditioning remote control request, it determines whether the current state of the vehicle meets the conditions. If so, it sends the air conditioning control request to the vehicle controller, which then controls the operation of the vehicle air conditioning accordingly. The technical solution of this application enables users to achieve flexible and efficient remote control of electric vehicle air conditioning.

[0060] The present application also provides another electric vehicle air conditioner remote control method, such as Figure 2 As shown, the method includes steps S201, S202, S203 and S204, wherein:

[0061] In step S201 , upon receiving an air conditioning control request, the mobile terminal forwards the air conditioning control request to the in-vehicle remote communication device.

[0062] Specifically, the mobile terminal can be a mobile phone or a tablet, and a vehicle control app can be set on the mobile terminal. When the user opens the vehicle control app and operates the air conditioning function on the vehicle control interface, it is considered that the mobile terminal has received the air conditioning control request.

[0063] In some optional embodiments, the air conditioning control request includes at least one of a cooling request, a heating request, a defrost request, a ventilation request, and a cabin cleaning request. For example, each air conditioning control request has a corresponding control in the vehicle control interface of the vehicle control app, and different icons and text descriptions are displayed on the control to indicate the function corresponding to the control. When the user presses a certain control, the control is triggered, and it is considered that the mobile terminal has received the air conditioning control request corresponding to the control. The air conditioning control request can carry an identification code that corresponds to the request type one by one. The identification code can be a binary code containing three bits. For example, the identification code corresponding to the cooling request is 000, the identification code corresponding to the heating request is 001, the identification code corresponding to the defrost request is 010, the identification code corresponding to the ventilation request is 011, and the identification code corresponding to the cabin cleaning request is 100.

[0064] In some optional embodiments, the air conditioning control request may further include an automatic request and an off request, where the identification code corresponding to the automatic request is 101, and the identification code corresponding to the off request is 110. The automatic request is a request made by the user when he or she wishes the air conditioning to operate in automatic mode.

[0065] The on-board telematics device can be a TBOX installed in the vehicle. It enables communication between the vehicle and other external devices. A mobile terminal can pre-establish a connection between the TBOXes using a mobile cellular network or satellite communications. Upon receiving an air conditioning control request, the mobile terminal forwards the request to the on-board telematics device via the mobile cellular network or satellite communications.

[0066] In step S202 , the vehicle-mounted remote communication device obtains the current state of the vehicle after receiving the air-conditioning control request.

[0067] In the embodiment of the present application, remote control of the vehicle's air conditioning requires that the vehicle meet certain conditions before it can be executed. For example, ensuring that the remaining power of the power battery is sufficient to ensure that the air conditioning is turned on without affecting the vehicle's driving, and ensuring that the doors and windows are closed to improve the efficiency of the air conditioning. Therefore, after receiving the air conditioning control request, the vehicle's onboard remote communication device will obtain the vehicle's current status.

[0068] Specifically, the vehicle-mounted remote control device can be connected to the body controller CEM, the vehicle controller VCU, the battery management module BMS and the air conditioning module ACCM using the CAN bus.

[0069] In some optional embodiments, the vehicle's current status includes the remaining battery power and the status of doors and windows. Upon receiving the air conditioning control request, the in-vehicle telematics device may obtain the remaining battery power from the battery management module (BMS) and the status of doors and windows from the vehicle control unit (CEM). In some optional embodiments, the in-vehicle telematics device may also indirectly obtain the remaining battery power from the battery management module (BMS) using the vehicle control unit (VCU).

[0070] In some optional embodiments, the current state of the vehicle may also include a high voltage power on state.

[0071] In some optional embodiments, when the air conditioning control request is a shutdown request, the shutdown request can be sent directly to the vehicle controller without obtaining the current state of the vehicle and determining whether the current state of the vehicle meets the preset state conditions.

[0072] In step S203 , when the vehicle-mounted remote communication device determines that the current state of the vehicle meets the preset state condition, it sends an air-conditioning control request to the vehicle controller.

[0073] In some optional embodiments, the judgment process in the above step S203 is specifically as follows: when it is detected that the remaining power is greater than the power threshold and the door and window status is closed, it is judged that the current state of the vehicle meets the preset state conditions.

[0074] In some optional embodiments, the power threshold can be pre-set according to the total capacity of the power battery, for example, it can be 30% of the total capacity of the power battery, so as to ensure that the subsequent normal driving of the vehicle is not affected when the air conditioner is remotely started.

[0075] It's understandable that whether doors and windows are closed only affects the efficiency of the air conditioning's cooling, heating, and ventilation processes. However, for cabin cleaning, the purifier may need to be activated, and if the doors and windows are left open, poor-quality outside air will continue to flow into the vehicle. Therefore, whether the doors and windows are closed directly affects the cabin cleaning results. Therefore, in some optional embodiments, determining whether the current door and window status is closed is only performed when the air conditioning control request is a cabin cleaning request. When the air conditioning control request is a cooling, heating, defrosting, ventilation, or automatic request, there is no need to check the current door and window status.

[0076] In some optional embodiments, the current state of the vehicle may also include a high-voltage power connection state. When the high-voltage power is not connected, it indicates that the vehicle is not powered on. At this time, the occupants are generally not inside the vehicle, and the current state of the vehicle meets the preset state conditions.

[0077] In some optional embodiments, as a parallel step of step S203 , when the vehicle-mounted remote communication device determines that the current state of the vehicle does not meet the preset state condition, a failure feedback is sent to the mobile terminal.

[0078] The mobile terminal displays a failure prompt based on the received failure feedback.

[0079] It is understandable that if the current state of the vehicle does not meet the preset state conditions, it means that it is not suitable to remotely start the car air conditioner at this time. In this case, a failure feedback will be sent to the mobile terminal to prompt the user that the car air conditioner failed to start.

[0080] The prompt text corresponding to the failure feedback may be "The current condition of the vehicle is not suitable for turning on the corresponding remote air conditioning function, please reconfirm the doors and windows and battery remaining power", and the specific reason may be displayed.

[0081] In step S204 , the vehicle controller controls the operation of the vehicle air conditioner according to the air conditioner control request.

[0082] It is understandable that before the vehicle controller controls the operation of the vehicle air conditioner according to the air conditioning control request, it is also necessary to judge the connection status of the high-voltage power and the air conditioning status. When the high-voltage power is in the disconnected state, the high-voltage power is connected; when the air conditioner is in the off state, a wake-up signal is sent to the air conditioner.

[0083] In some optional embodiments, in step S204, the vehicle controller controls the operation of the vehicle air conditioner according to the air conditioning control request, including at least one of the following:

[0084] According to the cooling request, the vehicle controller controls the vehicle air conditioner to start the compressor, switch the circulation mode to the internal circulation mode, switch the blowing mode to the surface blowing mode, switch the temperature to the lowest temperature, switch the air volume to the maximum air volume, and run for the first preset time.

[0085] In some optional embodiments, the first preset time may be 15 minutes.

[0086] In response to the heating request, the vehicle controller controls the vehicle air conditioner to activate the heater, switch the circulation mode to external circulation, switch the air blowing mode to blowing both the foot and the front windshield, switch the temperature to the highest temperature, switch the air volume to the maximum air volume, and operate the heater for a first preset time. In some optional embodiments, the heater is a high-voltage heating resistor.

[0087] According to the defrost request, the vehicle controller controls the vehicle air conditioner to turn on the heater, turn on the rear windshield heating wire and the rearview mirror heating wire, switch the circulation mode to the internal circulation mode, switch the blowing mode to the mode of blowing the front windshield, switch the temperature to the highest temperature, switch the air volume to the maximum air volume, and run for the first preset time.

[0088] In some optional embodiments, when the vehicle controller receives a defrost request, it can also obtain the vehicle's external temperature, determine whether the vehicle's external temperature is less than a temperature threshold, and adopt corresponding different defrost strategies to control the operation of the vehicle's air conditioner based on different judgment results.

[0089] Specifically, when the vehicle controller determines that the outside temperature is lower than the temperature threshold, the first defrost strategy is used to control the operation of the vehicle air conditioner for defrosting. The first strategy can be to turn on the heater, turn on the rear windshield heating wire and the rearview mirror heating wire, switch the circulation mode to the internal circulation mode, switch the blowing mode to the mode of blowing the front windshield, switch the temperature to the highest temperature, switch the air volume to the maximum air volume, and operate for the first preset time.

[0090] It is understandable that when the outside temperature is lower than the temperature threshold, it indicates that the vehicle may be severely frosted and difficult to remove. At this time, the vehicle air conditioner is controlled to operate at the highest temperature and maximum air volume to ensure defrosting efficiency.

[0091] When the vehicle controller determines that the outside temperature is not less than the temperature threshold, the second defrost strategy is used to control the operation of the vehicle air conditioner to perform defrosting. The second strategy can be to turn on the heater, turn on the rear windshield heating wire and the rearview mirror heating wire, switch the circulation mode to the internal circulation mode, switch the blowing mode to the mode of blowing the front windshield, switch the temperature to the first preset temperature, switch the air volume to the first preset air volume, and run for the first preset time, wherein the first preset temperature is lower than the maximum temperature of the air conditioner, and the first preset air volume is lower than the maximum air volume of the air conditioner.

[0092] It is understandable that when the outside temperature is not less than the temperature threshold, it indicates that the vehicle may be slightly frosted and the frost is less difficult to remove. At this time, the vehicle air conditioner is controlled to operate at a lower temperature and air volume, thereby saving power consumption while ensuring the defrosting effect.

[0093] In some optional embodiments, since frosting on the windshield has the greatest impact on driving, and the vehicle's onboard dashcam can capture frosting on the windshield, while the vehicle controller controls the operation of the vehicle's air conditioner according to the defrost strategy, it can also control the onboard dashcam to turn on, obtain video data recorded by the dashcam, and forward the video data to the mobile terminal in real time via the vehicle's remote communication device. The video data is then displayed on the mobile terminal, allowing the user to monitor the defrosting effect in real time using the mobile terminal. When the user is satisfied with the defrosting effect, they can directly touch the mobile terminal to request remote shutdown of the air conditioner. Based on the user's touch operation, the mobile terminal generates a corresponding end request, which is forwarded to the vehicle controller via the vehicle's remote communication device, ultimately controlling the vehicle's onboard air conditioner to shut down, thereby further ensuring the defrosting effect while saving power consumption.

[0094] In the above step S204, the vehicle controller controls the operation of the vehicle air conditioner according to the air conditioning control request, which also includes at least one of the following: the vehicle controller controls the vehicle air conditioner to turn on the purifier according to the ventilation request, switches the circulation mode to the external circulation mode, switches the blowing mode to the face blowing mode, switches the air volume to the maximum air volume, and operates for the second preset time.

[0095] It will be appreciated that the purifier may be a negative ion generator.

[0096] According to the cabin cleaning request, the vehicle controller controls the vehicle air conditioner to turn on the heater and purifier, switch the circulation mode to the internal circulation mode, switch the blowing mode to the mode of blowing the feet and the face at the same time, switch the temperature to the highest temperature, switch the air volume to the maximum air volume, and run for the second preset time.

[0097] It is understandable that, since it takes longer to adjust the air condition inside the vehicle than to adjust the temperature, the second preset time is greater than the first preset time.

[0098] In some optional embodiments, the second preset time may be 30 minutes.

[0099] In some optional embodiments, the vehicle controller controls the vehicle air conditioner to turn on the heater and purifier based on the cabin cleaning request, switches the circulation mode to the internal circulation mode, switches the blowing mode to the mode of blowing the feet and the face at the same time, switches the temperature to the highest temperature, switches the air volume to the maximum air volume, and runs for the second preset time. At the same time, the vehicle controller controls the speakers in the vehicle to play a heating warning sound, which is used to remind the passengers in the vehicle that the cabin is about to heat up.

[0100] It is understandable that, because the air conditioning temperature will be switched to the highest temperature and continue to operate for a long time during the cabin purification process, the temperature inside the vehicle may rise significantly. If there are still passengers in the vehicle at this time, it may have a significant impact on the passengers' physical sensations and even cause dangerous conditions such as heat stroke. Therefore, in the process of controlling the vehicle air conditioning to purify the cabin according to the cabin purification request, it is also necessary to control the vehicle speakers to play a temperature increase warning sound. The temperature increase warning sound can be only warning music without voice, or it can include both warning music and voice. The voice can be a looped "Cabin purification mode is on, the temperature inside the vehicle is about to rise, please leave the vehicle as soon as possible" to avoid threats to the safety of passengers in the case that there are still passengers in the vehicle or even if the passengers fall asleep in the vehicle.

[0101] In some optional embodiments, after the vehicle controller receives a cabin cleaning request and before purifying the cabin according to the cabin cleaning request, it may also forward a secondary confirmation request to the mobile terminal using the vehicle's remote communication device. After receiving the secondary confirmation request, the mobile terminal displays on the interface the message "After this function is executed, the temperature inside the vehicle will be high. Please confirm that there are no flammable or explosive items or pets or children in the vehicle, and that the vehicle will not be used for a short period of time" and monitors the user's click on the "Confirm" control. When the mobile terminal detects the click on the "Confirm" control, it forwards the confirmation command to the vehicle controller using the vehicle controller. The vehicle controller only begins controlling the air conditioner to purify the cabin after receiving the confirmation command, thereby further ensuring the safety of the vehicle and its passengers.

[0102] In some optional embodiments, in the above step S204, the vehicle controller controlling the operation of the vehicle air conditioner according to the air conditioning control request further includes: the vehicle controller controlling the vehicle air conditioner to switch to automatic mode according to the automatic request.

[0103] It is understandable that when the car air conditioner is in automatic mode, it will automatically adjust the temperature, air volume and blowing mode according to the temperature of various locations in the car, so as to maintain the temperature in the car at a temperature suitable for the human body, such as 26 degrees Celsius.

[0104] In some optional embodiments, during the process of the vehicle controller controlling the operation of the vehicle air conditioner according to the air conditioning control request in the above step S204, the vehicle controller can also monitor the real-time status of the air conditioner and use the vehicle-mounted remote communication device to feed back the real-time status of the air conditioner to the mobile terminal, and the mobile terminal displays a corresponding animation based on the real-time status of the air conditioner. For example, when a certain function of the air conditioner is turned on, the button control of the corresponding function on the app is highlighted, and when the function is turned off, the button control is not illuminated. In addition, when the air conditioner is cooling, the interface on the app displays a blue gas effect, and when the air conditioner is heating, the interface on the app displays a red gas effect, thereby allowing the user to intuitively monitor the current status of the air conditioner using the mobile terminal app.

[0105] In some optional embodiments, in the above step S204, the vehicle controller controlling the operation of the vehicle air conditioner according to the air conditioning control request further includes: the vehicle controller controlling the vehicle air conditioner to shut down according to the shut down request.

[0106] In some optional embodiments, since the status of the vehicle may change during the remote control of the vehicle air conditioner, such as the doors and windows are opened, the power battery remaining is low, or the charging status changes, the vehicle controller controls the operation of the vehicle air conditioner according to the air conditioning control request while also measuring the charging port status and continuing to obtain the current status of the vehicle.

[0107] It's understandable that fuel vehicles must be turned off during refueling, but due to the specific structure and usage scenarios of electric vehicles, they can continue to use power during slow and fast charging, and the air conditioning can continue to be turned on. However, if the charging port malfunctions or there is a need to unplug the fast charging gun, the high voltage power must be disconnected to ensure safety. In this case, the air conditioning control is interrupted.

[0108] Specifically, the process for determining whether a charging port has failed can be as follows: during fast charging, the operating status of the DC-DC transformer is determined. If the DC-DC transformer fails, the charging port is determined to have failed. During slow charging, the operating status of the AC-DC transformer is determined. If the AC-DC transformer fails, the charging port is determined to have failed.

[0109] In some optional embodiments, the specific response strategy after the air conditioner remote control is interrupted is as follows:

[0110] When the vehicle controller detects that the charging port is in a fault state, or the charging port is in a fast charging gun removal state, or the current state of the vehicle does not meet the preset state conditions, the air conditioner is turned off and an interrupt feedback is sent to the on-board remote communication device, where the fast charging gun removal state indicates that the fast charging gun unlock button is pressed.

[0111] The in-vehicle remote communication device forwards the received interrupt feedback to the mobile terminal.

[0112] The mobile terminal displays an interruption prompt according to the received interruption feedback.

[0113] The prompt text corresponding to the interruption prompt may be "The current condition of the vehicle has changed, the air conditioning remote control has been interrupted, please reconfirm the vehicle condition."

[0114] In some optional embodiments, in addition to the interruption of air conditioning control due to opening doors and windows, low power battery remaining level or change in charging status, local takeover by the driver and passengers may also cause remote control of the air conditioning to be interrupted.

[0115] The vehicle controller controls the operation of the vehicle air conditioner according to the air conditioning control request while monitoring the door lock status and the one-touch start button status.

[0116] When the vehicle controller detects that the door lock status changes from locked to unlocked, or the one-touch start button is pressed, the air conditioner is turned off and a local takeover feedback is sent to the vehicle remote communication device.

[0117] The vehicle-mounted remote communication device forwards the received local takeover feedback to the mobile terminal.

[0118] The mobile terminal displays a local takeover prompt based on the received local takeover feedback. The local takeover prompt is used to remind the user that the vehicle has been locally taken over by the driver.

[0119] It is understandable that if the door lock changes from a locked state to an unlocked state, or the opinion start button is pressed, it means that a driver or passenger has come to the vehicle or even sat in the vehicle. At this time, the air conditioner can be turned off and the air conditioner can be controlled locally by the driver or passenger.

[0120] In some optional embodiments, when the vehicle controller detects that the one-touch start button is pressed, it may not turn off the air conditioner, but instead control the air conditioner to switch to the vehicle air conditioner state before the last power outage that is memorized.
