Technical Field

[0003] The present application relates to the field of vehicle auxiliary technology, and in particular to a control method, device, electronic device and storage medium for a vehicle air conditioner. Background Art

[0004] With the booming development of automotive electronics, cockpit systems are becoming increasingly sophisticated. New cars are often equipped with iconic screens, and each generation integrates more functions than the previous one. Currently, many cars have eliminated physical buttons in the center console, integrating all key functions into the large onboard screen. For example, the air conditioning system buttons are also integrated into the large screen, including the air conditioning mode adjustment, air volume adjustment, and defrost control. However, integrating the air conditioning buttons into the large screen can make it impossible to operate the buttons on the large screen if there is a problem with the cockpit system or the large screen. In the summer, the air conditioning will not turn on, affecting passenger cabin comfort. In the spring and autumn, fogged windows will obstruct the driver's view. If the large screen is faulty and the vehicle is not equipped with automatic defogger, the defogger function will not be activated, posing a driving safety risk. In the winter, the heating and window defrost will not turn on, affecting not only driving comfort but also driving safety. Summary of the Invention

[0049] The following will describe the embodiments of the present application with reference to the accompanying drawings and optional embodiments. Those skilled in the art can easily understand other advantages and effects of the present application from the contents disclosed in this specification. The present application can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present application. It should be understood that the optional embodiments are only for the purpose of illustrating the present application and are not intended to limit the scope of protection of the present application.

[0050] The first embodiment of the present application provides a method for controlling a vehicle air conditioner. The method can be applied to the system architecture shown in Figure 1. The system architecture includes at least a controller 101 and a vehicle air conditioner 102, and the controller 101 and the vehicle air conditioner 102 establish a communication connection. The method can be applied to the controller 101 in the system architecture. Specifically, the system architecture can be a vehicle, and the type of vehicle is not limited. For example, it can be a fuel vehicle, a pure electric vehicle, a hybrid vehicle, or a fuel cell vehicle, etc. The vehicle air conditioner can be a heating and ventilation air conditioner that can cool, heat, ventilate, etc.

[0051] Next, based on the system architecture, the control method of the vehicle air conditioner is described in detail. As shown in FIG2 , the control method of the vehicle air conditioner includes:

[0052] Step 201 : When an abnormality occurs in the cabin system of the vehicle, obtain the ambient temperature outside the vehicle.

[0053] In one embodiment, the cockpit system abnormality includes at least the following two situations:

[0054] In the first case, the vehicle controller and the cockpit system cannot establish a communication connection. In this case, the virtual buttons of the vehicle air conditioner are inoperative.

[0055] In the second case, the controller maintains a communication connection with the cockpit system and obtains a fault signal from the cockpit system; wherein the fault signal is a fault signal indicating that a virtual button of the vehicle air conditioner is invalid.

[0056] In any of the above situations, it can be judged that there is an abnormality in the cabin system, thereby turning on the automatic adjustment function of the car air conditioner.

[0057] Step 202 : determining a target mode of the vehicle air conditioner corresponding to the ambient temperature outside the vehicle from a preset mapping relationship; wherein the mapping relationship is a mapping relationship between temperature ranges and operating modes of the vehicle air conditioner.

[0058] The mapping relationship between temperature ranges and vehicle air-conditioning operating modes can be pre-set, so that different operating modes can be operated according to the different temperature ranges (i.e. different temperature gradients) of the ambient temperature outside the vehicle. For example, cooling can be turned on in a high temperature range, heating can be turned on in a low temperature range, or windows can be defrosted in a temperature range that is prone to frosting.

[0059] In one embodiment, determining a target mode of a vehicle air conditioner corresponding to an outside ambient temperature from a preset mapping relationship includes: obtaining a mapping relationship; determining a target temperature range corresponding to the outside ambient temperature; and determining a target mode corresponding to the target temperature range from the mapping relationship.

[0060] In this embodiment, the mapping relationship can be obtained first, and then it is determined which target temperature range the current outdoor ambient temperature is in within the mapping relationship. Then, the corresponding target mode is searched in the mapping relationship according to the target temperature range, so that the control of the vehicle air conditioner can be started conveniently and quickly.

[0061] Step 203: Control the vehicle air conditioner according to the target mode.

[0062] This method determines the target mode of the vehicle air conditioner by obtaining the ambient temperature outside the vehicle when an abnormality occurs in the cockpit system, that is, when the virtual buttons of the vehicle air conditioner fail to function, and controls the vehicle air conditioner according to the target mode. This solves the problem that the vehicle air conditioner cannot be turned on when the virtual buttons on the large screen cannot be operated in the scenario where the air conditioner buttons are all integrated into the large screen, thereby improving driving comfort and safety.

[0063] When the ambient temperature outside the vehicle is in different temperature ranges, the vehicle air conditioner is controlled according to different target modes.

[0064] In one embodiment, the specific target mode may be as follows:

[0065] When the ambient temperature outside the vehicle is greater than or equal to the first temperature, the target mode is the first operating mode, and the vehicle's onboard air conditioner is controlled according to the target mode, including: controlling the onboard air conditioner to turn on and starting the vehicle's compressor; dynamically adjusting the air volume and damper opening of the onboard air conditioner so that the temperature of the passenger compartment meets the preset target temperature; wherein the preset target temperature is lower than the first temperature.

[0066] In this embodiment, for example, the first temperature is 30°C. When the ambient temperature outside the vehicle is ≥30°C, the vehicle air conditioner is controlled according to the first operating mode. For example, the vehicle air conditioner is controlled to turn on and the compressor is started. The air volume and the damper opening are dynamically adjusted to make the temperature of the passenger compartment meet the preset target temperature. The preset target temperature is a temperature that is more comfortable for the driver and passengers in the vehicle, such as 25°C.

[0067] When the ambient temperature outside the vehicle is lower than the first temperature and greater than or equal to the second temperature, the target mode is the second operating mode, and the vehicle's onboard air conditioner is controlled according to the target mode, including: controlling the onboard air conditioner to turn on the defrost mode, and starting the vehicle's compressor and electric heater; adjusting the damper of the onboard air conditioner to the defrost position, and adjusting the blower of the onboard air conditioner to operate according to the first target gear.

[0068] In this embodiment, for example, the first temperature is 30°C and the second temperature is 0°C. When 0°C ≤ the outside ambient temperature < 30°C, the vehicle air conditioner is controlled according to the second operating mode. For example, the vehicle air conditioner is controlled to turn on the defrost mode, and the compressor and electric heater are started; the damper of the vehicle air conditioner is adjusted to the defrost position, and the blower is adjusted to operate according to the first target gear, wherein the first target gear is the gear of the blower air volume. If the blower includes 8 gears, the first target gear can be gear 3 without restriction.

[0069] When the ambient temperature outside the vehicle is lower than the second temperature and greater than or equal to the third temperature, the target mode is the third operating mode, and the vehicle's onboard air conditioner is controlled according to the target mode, including: controlling the onboard air conditioner to turn on the defrost foot blowing mode and starting the vehicle's electric heater; adjusting the damper of the onboard air conditioner to the defrost foot blowing position, and adjusting the blower of the onboard air conditioner to operate according to the second target gear; wherein the air volume of the second target gear is greater than the air volume of the first target gear.

[0070] In this embodiment, for example, the second temperature is 0℃ and the third temperature is -10℃, when -10℃≤the outside ambient temperature<0℃, the vehicle air conditioner is controlled according to the third operating mode. For example, the vehicle air conditioner is controlled to turn on the defrost foot blowing mode and start the electric heater; the air damper of the vehicle air conditioner is adjusted to the defrost foot blowing position, and the blower is adjusted to operate according to the second target gear. The second target gear can be gear 5 without restriction.

[0071] When the ambient temperature outside the vehicle is lower than the third temperature, the target mode is the fourth operating mode, and the vehicle's onboard air conditioner is controlled according to the target mode, including: controlling the onboard air conditioner to turn on the defrost mode, and adjusting the onboard air conditioner's blower to operate according to the third target gear; when the defrost mode runs for the first time, switching to the defrost foot blowing mode, and running for the second time; when the temperature of the passenger compartment meets the preset target temperature, adjusting the blower to operate according to the second target gear, wherein the air volume of the second target gear is smaller than the air volume of the third target gear.

[0072] In this embodiment, for example, when the third temperature is -10°C and the ambient temperature outside the vehicle is less than -10°C, the vehicle air conditioner is controlled according to the fourth operating mode. For example, the vehicle air conditioner is controlled to activate the defrost mode and adjust the blower to operate at the third target gear. When the defrost mode operates for a first time, the blower is switched to the defrost foot blowing mode and operates for a second time. When the passenger compartment temperature meets the preset target temperature, the blower is adjusted to operate at the second target gear. The third target gear may be gear 8. The first time may be 3 minutes and the second time may be 1 minute, without limitation. Furthermore, if the passenger compartment temperature does not meet the preset target temperature, the vehicle air conditioner may cycle between the defrost mode and the defrost foot blowing mode. For example, the vehicle air conditioner may operate in the defrost mode and the blower at gear 8 for 3 minutes, then switch to the defrost foot blowing mode for 1 minute, maintaining the blower at gear 8 during this period. After 1 minute, the blower is switched back to the defrost mode for 3 minutes, and this cycle continues until the passenger compartment temperature meets the preset target temperature, for example, reaching 25°C, at which point the blower is adjusted to operate at gear 5.

[0073] In a specific embodiment, a hardware connection diagram of a vehicle air-conditioning control method is shown in Figure 3. The cockpit controller and the large screen in the passenger compartment are connected via a controller area network bus (CAN bus) or a CANFD (CAN with Flexible Data-Rate) bus or Ethernet. The cockpit controller and the controller are connected via CAN communication or CANFD communication or Ethernet communication. The external temperature sensor and the controller are connected via a hard wire to collect the temperature outside the vehicle. The controller and the vehicle air-conditioning are connected via a hard wire or a local interconnect network (LIN) communication for driving and signal collection. The controller and the compressor are connected via CAN communication or LIN communication for driving and signal collection. The controller and the electric heater are connected via CAN communication or LIN communication for driving and signal collection.

[0074] In this embodiment, a flow chart of the vehicle air conditioning control method is shown in Figure 4. When the vehicle is powered on, the controller detects the outdoor ambient temperature T1 and establishes communication with the cabin system. If communication is established normally and there are no cabin system fault signals on the communication network, the system determines that the cabin system is operating normally and the air conditioning system begins to operate based on the user's settings. If the controller and the cabin system cannot establish normal communication, or if normal communication can be established but there are cabin system fault signals on the communication network, it is determined that the cabin system has failed and the user cannot control and operate the air conditioning system normally. In this case, the controller detects the outdoor ambient temperature based on the external temperature sensor and controls the air conditioning system to different modes based on different outdoor ambient temperatures, as follows:

[0075] When the ambient temperature outside the vehicle T1 ≥ 30℃, the controller controls the air conditioner to turn on, controls the compressor, controls the target temperature in the passenger compartment at 25℃, and automatically adjusts the air volume and air door opening.

[0076] When the outside ambient temperature is 0℃≤T1<30℃, the controller controls the air conditioner to turn on the defrost mode, controls the compressor and electric heater, and adjusts the vehicle air conditioner damper to the defrost position, and sets the blower air volume to level 3.

[0077] When the outside ambient temperature T1 is less than or equal to -10℃ and is less than 0℃, the controller controls the air conditioner to turn on the defrost foot blowing mode to control the electric heater, adjusts the vehicle air conditioner mode to the defrost foot blowing mode, and sets the blower air volume to level 5.

[0078] When the ambient temperature outside the vehicle T1 is less than -10℃, the controller controls the air conditioner to turn on the defrost mode first, with the blower air volume at level 8. After the air conditioner system runs in the defrost mode for 3 minutes, it switches to the defrost foot blowing mode, with the blower air volume still maintained at level 8, running for 1 minute, and then repeating the cycle until the head temperature in the vehicle reaches 25℃, at which point the blower air volume is reduced to level 5.

[0079] In this embodiment, when a problem occurs in the cockpit system and the virtual buttons on the large screen inside the car become ineffective, the system can automatically determine the corresponding mode of the car air conditioner based on the current ambient temperature outside the car, and automatically turn on the passenger compartment cooling, heating or window defogger function to meet the comfort of the passenger compartment and the driving safety of the vehicle.

[0080] Based on the same technical concept, the second embodiment of the present application provides a control device for a vehicle air conditioner, as shown in FIG5 , the device includes:

[0081] The acquisition module 501 is used to obtain the ambient temperature outside the vehicle when an abnormality occurs in the vehicle's cabin system;

[0082] A determination module 502 is configured to determine a target mode of the vehicle air conditioner corresponding to the vehicle external ambient temperature from a preset mapping relationship; wherein the mapping relationship is a mapping relationship between temperature ranges and vehicle air conditioner operating modes;

[0083] The control module 503 is configured to control the vehicle air conditioner according to the target mode.

[0084] When an abnormality occurs in the cockpit system, that is, when the virtual buttons of the vehicle air conditioner fail to function, this device determines the target mode of the vehicle air conditioner by obtaining the ambient temperature outside the vehicle, and controls the vehicle air conditioner according to the target mode. This solves the problem that the vehicle air conditioner cannot be turned on when the virtual buttons on the large screen cannot be operated in the scenario where the air conditioner buttons are integrated into the large screen, thereby improving driving comfort and safety.
