[0033] Embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0034] The following describes a method for controlling a vehicle air conditioner, a controller, a computer-readable storage medium, a control device for a vehicle air conditioner, and a vehicle proposed in an embodiment of the present application with reference to the accompanying drawings.

[0035] In the related art, the user needs to first enter the vehicle to start the vehicle, and then start the air conditioner through a knob or an on-board electronic screen. This causes the temperature inside the vehicle to reach a comfortable effect only after the user has entered the vehicle for a period of time, reducing the comfort of the passengers.

[0036] In order to solve the above technical problems, the present application proposes a control method for a vehicle air conditioner, which reuses the locking button of the remote control key, and remotely controls the vehicle air conditioner without increasing the hardware cost. The air conditioner can be turned on in advance before the user enters the car, and the temperature in the car can be adjusted to improve people's driving comfort. The control method for the vehicle air conditioner of the present application is described in detail below with reference to the accompanying drawings.

[0037] Figure 1 Flow chart of a method for controlling a vehicle air conditioner according to an embodiment of the present application.

[0038] like Figure 1 As shown, the control method of the vehicle air conditioner in the embodiment of the present application includes:

[0039] S1, obtain the current status of the vehicle;

[0040] S2, when the current state of the vehicle is within the preset state set, obtaining the target parameter according to the current state of the vehicle;

[0041] S3, when the target parameters meet the preset activation conditions, in response to a locking signal triggered by the remote control key within a preset range and lasting for a preset time, the vehicle air conditioner is controlled to enter the target operation mode.

[0042] Specifically, the current state of the vehicle can be awakened and acquired after receiving a lock button trigger signal of the remote control key. The current state can be a parking state, an emergency power-off state, a power-on state, a running state, etc.

[0043] The preset state set includes at least one target state, and the target state is an operating state that allows the vehicle to wake up the air conditioner based on the locking signal, which is set according to the actual situation. When the current state of the vehicle is within the preset state set, it is considered that the current vehicle state allows remote wake-up and start-up of the vehicle air conditioner, and then the target parameter is obtained according to the current state of the vehicle. In the preset state set, each target state corresponds to a different target parameter, and the target parameter is used to evaluate the state data of the vehicle to determine whether it meets the conditions for starting the vehicle air conditioner. For example, when the vehicle is in a parking and power-off state, the power of the energy storage battery and the state of the power supply path can be used as the target parameter; when the vehicle is in a power-on state, the state of the power supply path can be used as the target parameter. Specifically, a preset state set and a mapping relationship between each target state and the target parameter in the preset state set can be established in advance, so as to determine the target parameter according to the current state of the vehicle based on the mapping relationship. In addition, the preset state set and the mapping relationship between each target state and the target parameter in the preset state set can also be customized in combination with the vehicle identification and user needs (such as age, gender, etc.) to meet the usage habits of different users and the performance requirements of different vehicles.

[0044] The target parameters are obtained according to the current state of the vehicle, and then the obtained target parameters are compared with the preset activation conditions. If the target parameters meet the preset activation conditions, it is determined that the vehicle allows the vehicle air conditioner to be powered on and started. When the remote control key is within the preset range to trigger the locking signal and the duration of the locking signal reaches the preset duration, the vehicle air conditioner is controlled to start and enter the target operation mode. If the target parameters do not meet the preset activation conditions, it is determined that the vehicle does not allow the vehicle air conditioner to be powered on and started, and the current state of the vehicle air conditioner remains unchanged. Among them, the preset activation condition is a preset range setting for each target state in the preset state set, which is used to evaluate whether the current vehicle meets the air conditioner power-on operation.

[0045] The locking signal for starting the vehicle air conditioner requires the remote control key to be within a certain range (preset range) from the vehicle, and is triggered by the user long pressing the remote control key's "lock" hard button. If the remote control key is outside the preset range or the long press time of the "lock" hard button does not reach the preset time, the vehicle air conditioner start function will not be triggered. The preset range can be set according to the effective distance of the remote control key to the vehicle.

[0046] The target operation mode can be defined according to user characteristics to meet the different user comfort levels. Specifically, user characteristics can be obtained by entering the owner's information, including gender, age, custom characteristics, etc. For example, when the user is female, the temperature of the target operation mode is set to 26°C, and when the user is male, the temperature of the target operation mode is set to 25.5°C. The operating parameters of the target operation mode can be adjusted in combination with the current environmental information to adjust the adjustment rate of the in-vehicle environment. For example, when the in-vehicle ambient temperature is within the preset temperature range, the target operation mode can be operated based on the set wind speed and set temperature; when the in-vehicle ambient temperature exceeds the preset temperature range, the air volume can be increased and / or the set temperature of the current target operation mode can be lowered to speed up the cooling speed in the vehicle; when the in-vehicle ambient temperature is lower than the preset temperature range, the air volume can be increased and / or the set temperature of the current target operation mode can be increased to speed up the heating in the vehicle. In addition, the target operation mode can also set the operation parameters in combination with the current state of the vehicle and the specific data of the target parameters to match different vehicle states. For example, when the battery power in the target parameter is less than 30%, the wind speed of the car air conditioner is lowered to reduce energy consumption and avoid excessive discharge; when the battery power in the target parameter is greater than or equal to 30%, it can operate at the set wind speed; when the battery power in the target parameter is greater than 50%, the wind speed can be increased based on actual conditions, etc.

[0047] Therefore, this embodiment evaluates the vehicle performance through the current state and target parameters of the vehicle to ensure the stability of the remote power-on of the vehicle air conditioner, that is, when the current state of the vehicle is within the preset state set and the corresponding target parameters meet the activation conditions, the remote start signal is responded to and the vehicle air conditioner is controlled, which can realize the early start of the vehicle air conditioner and improve the riding comfort. At the same time, the activation judgment is made in combination with the vehicle state and the corresponding target parameters, which improves the start-up control accuracy of the air conditioner, makes the air conditioner control match the current vehicle performance, and ensures the applicability of the start-up control of the vehicle air conditioner on the current vehicle. Based on this control method, the user can use the remote control key to issue instructions, the control system inside the vehicle receives the instructions and performs corresponding processing, and drives the execution of the air conditioning system to complete the corresponding action.

[0048] In one embodiment of the present application, the vehicle includes a battery, which supplies power to the vehicle air conditioner through a DC converter. The preset state set includes a key power gear off state and a key power gear on state. When the current state of the vehicle is within the preset state set, the target parameters are obtained according to the current state of the vehicle, including: when the vehicle is in the key power gear off state, obtaining the remaining power of the battery, the working state of the DC converter and the voltage of the battery; when the vehicle is in the key power gear on state, obtaining the working state of the DC converter and the voltage of the battery.

[0049] That is to say, the preset state set includes the key power gear off state and the key power gear on state. When the current state of the vehicle is the key power gear off state, the target parameters include the remaining battery power, the working state of the DC converter and the battery voltage, which are used to evaluate whether the vehicle in the key power gear on state meets the preset activation conditions. When the current state of the vehicle is the key power gear on state, the target parameters include the working state of the DC converter and the battery voltage, which are used to evaluate whether the vehicle in the key power gear on state meets the preset activation conditions.

[0050] In one embodiment of the present application, when the vehicle is in the key power gear off state, when the remaining power of the battery is greater than the preset power threshold, the DC converter is in the working state and the battery voltage is greater than the preset voltage, it is determined that the target parameter meets the preset activation condition; when the vehicle is in the key power gear on state, when the DC converter is in the working state and the battery voltage is greater than the preset voltage, it is determined that the target parameter meets the preset activation condition. Among them, the preset power threshold and the preset voltage can be set according to actual conditions.

[0051] Specifically, assuming that the preset power threshold is 20% and the preset voltage is 12.5V. Then, when the current state is the key power gear off state, the preset activation condition is that the key power gear = OFF, SOC (State Of Charge, remaining power) is greater than 20%, the DC converter is in working state, and the battery voltage is greater than 12.5V. When the current state is the key power gear on state, the preset activation condition is that the key power gear = ON, the DC converter is in working state, and the battery voltage is greater than 12.5V.

[0052] When the preset activation conditions are met, if a trigger action is received, that is, within a certain range of the vehicle, the user can long press the "lock" hard button of the remote control key to start the car air conditioner.

[0053] In one embodiment of the present application, controlling the vehicle air conditioner to enter the target operation mode includes: controlling the vehicle air conditioner to enter the fully automatic mode, and setting the target temperature of the vehicle air conditioner to a preset temperature. The preset temperature can be set according to actual conditions.

[0054] Specifically, taking the preset temperature of 26°C as an example, when the user turns on the car air conditioner by long pressing the "lock" hard button of the remote control key, the car air conditioner automatically enters the AUTO (Automatic mode) gear and the temperature is set to 26°C. The preset temperature can be automatically adjusted according to the current ambient temperature and the current temperature inside the car, so that the car quickly reaches a comfortable temperature.

[0055] In one embodiment of the present application, when the vehicle is in the key power gear off state, in response to the locking signal triggered by the remote control key within the preset range and the duration reaches the preset duration, after the vehicle air conditioner is controlled to enter the target operation mode, the control method of the vehicle air conditioner further includes: when the operation time of the vehicle air conditioner is greater than the preset operation time and the vehicle is in the key power gear off state, the vehicle air conditioner is controlled to shut down; when the operation time of the vehicle air conditioner is less than or equal to the preset operation time and the vehicle enters the key power gear on state from the key power gear off state, the vehicle air conditioner is controlled to continue to operate in the target operation mode; when the vehicle is in the key power gear on state, in response to the locking signal triggered by the remote control key within the preset range and the duration reaches the preset duration, after the vehicle air conditioner is controlled to enter the target operation mode, the control method of the vehicle air conditioner further includes: when the vehicle enters the key power gear off state from the key power gear on state, the vehicle air conditioner is controlled to shut down. Among them, the preset operation time can be set according to actual conditions.

[0056] Specifically, take the preset running time of 15 minutes as an example. If the vehicle is in the key power gear off state, the vehicle air conditioner is turned on based on the above method, and the running time of the vehicle air conditioner is timed. If the vehicle has not entered the ON gear, that is, the key power gear is turned on, when the working time of the vehicle air conditioner exceeds 15 minutes, the vehicle is controlled to automatically shut down; if the vehicle enters the ON gear from the OFF gear when the working time of the vehicle air conditioner is less than or equal to 15 minutes, the vehicle air conditioner continues to execute according to the current state until a new instruction is issued, and the timing is reset and canceled. At the same time, when the vehicle is in the key power gear off state, when the vehicle air conditioner is turned on based on the above method, the left and right turn signals can be controlled to flash twice for control feedback reminder. If the vehicle is in the ON gear, that is, the key power gear is turned on, and the vehicle air conditioner is turned on based on the above method, if the key power gear changes from ON to OFF, the vehicle air conditioner is directly turned off.

[0057] That is to say, when the air conditioning function is activated, the air conditioning function can be exited when any of the following situations occurs: the user long presses the "lock" hard button of the remote control key (within a certain range from the vehicle); the user clicks the large-screen air conditioning off soft button; SOC≤20% in OFF gear; battery voltage≤12.5V; high-voltage enable flag; air conditioning operation timeout of 15 minutes in OFF gear.

[0058] In one embodiment of the present application, when the vehicle is in an emergency power-off state, no response is given to a locking signal triggered by the remote control key within a preset range and lasting for a preset time.

[0059] In other words, the vehicle fault strategy and handling mechanism are set to not respond to the remote control key's request to turn on the air conditioner during the vehicle's emergency power-off period.

[0060] As a specific embodiment of the present application, the system architecture of the vehicle can be as follows: Figure 2 As shown, RKE (Remote Keyless Entry) is a system that controls vehicle door locks and engine start through wireless signals, including a remote control (remote control key) and a receiver. The remote control is held by the owner and is used to send instructions for unlocking, locking the vehicle and starting the engine, while the receiver is installed on the vehicle to receive and process these instructions. RFR (Radio Frequency Receiver) is a core component in the PEPS (Passive Entry Passive Start) system, responsible for receiving the high-frequency unlocking signal from the Bluetooth key, and then passing the signal to the vehicle lock module to unlock the door. In this control method, RFR receives the air conditioning on / off request sent by the remote control key and sends it to the CEM (Body Control Module), where the CEM is responsible for managing and controlling various electronic devices and functions of the vehicle and can execute the above control method.

[0061] BMS (Battery Management System) is an electronic device used to monitor, manage and protect the battery system. It collects various parameters of the battery in real time, such as voltage, current, temperature, etc., and performs accurate analysis and calculation based on these parameters, so as to effectively control and manage the battery system, maximize the performance advantages of the battery, effectively extend the battery life, and ensure the safety of the battery during use. CMDC (Charge Module & DCDC Converter) is responsible for converting AC power into DC power to charge the battery of electric vehicles, usually including DCDC converter and charging module. VCU (Vehicle Control Unit) is responsible for collecting and processing various signals, coordinating the work of various subsystems of the vehicle, and ensuring the efficient and safe operation of the vehicle. TMM (Temperature Management Module) is a system for managing the internal temperature of the vehicle. It mainly realizes the switching of three operating areas: engine warm-up, target temperature control area and cooling control after shutdown. Through sensor technology and automated control algorithms, it monitors and adjusts the temperature of the vehicle to ensure that the engine and other key components operate within the optimal operating temperature range, thereby improving fuel efficiency and driving experience. The EAC (Electronic Acceleration Controller) improves the engine's response performance by optimizing the signal of the accelerator pedal sensor, thereby enhancing the vehicle's acceleration ability and driving experience. The water-heating PTC (Positive Temperature Coefficient) heater is mainly used for preheating and heating the car's cab or engine. The PTC heater provides heat by heating the coolant, which then flows through the warm air core in the cab, and the air is circulated and heated by the heat core through the blower, thereby realizing the heating function of the cab. The negative ion generator is a device that can generate a large number of negative ions. It is installed inside the car and is mainly used to improve the air quality in the car and improve the health and comfort of the driver and passengers. The negative ion generator can effectively remove harmful gases, bacteria and viruses in the car by releasing negative ions. At the same time, it can also improve the air quality and improve the driver's mental state and health. The main function of the chiller (battery cooler) electronic valve is to introduce the refrigerant in the air conditioning system, evaporate after the expansion valve throttling, absorb the heat of the coolant in the battery cooling circuit, and take away the heat of the coolant through heat exchange, thereby cooling the battery. IGN2 REALY refers to the second power supply relay of the ignition system, which is used to control the power supply to the ignition coil to ensure that the engine can start and run normally.

[0062] As a specific embodiment of the present application, Figure 3 As shown, the control method of the vehicle air conditioner may include the following steps:

[0063] S101, obtaining the current state of the vehicle.

[0064] S102, when the vehicle is in the OFF position (ie, the key power position is off), the remaining battery capacity SOC, the working state of the DC converter and the battery voltage are obtained.

[0065] S103, determine whether the SOC is greater than 20%, the DC converter is in working state and the battery voltage is greater than 12.5 V. If yes, execute step S104; if no, execute step S116.

[0066] S104, in response to a locking signal triggered by the remote control key within a preset range and lasting for a preset time, the vehicle air conditioner is controlled to enter a fully automatic mode with a temperature of 26°C.

[0067] S105, obtaining the actual operating time of the vehicle air conditioner.

[0068] S106, determine whether the actual running time is greater than 15 minutes. If yes, execute step S109; if no, execute step S107.

[0069] S107, determine whether the vehicle is in the ON position (ie, the key power position is turned on). If yes, execute step S108; if no, execute step S105.

[0070] S108, the vehicle air conditioner continues to execute according to the current state until a new instruction is issued, and the timer is reset and canceled.

[0071] S109, controlling the vehicle air conditioner to shut down.

[0072] S110, when the vehicle is in the ON gear, obtaining the working state of the DC converter and the voltage of the battery.

[0073] S111, determine whether the DC converter is in working state and the battery voltage is greater than 12.5 V. If yes, execute step S112; if no, execute step S116.

[0074] S112, in response to a locking signal triggered by the remote control key within a preset range and lasting for a preset time, the vehicle air conditioner is controlled to enter a fully automatic mode with a temperature of 26°C.

[0075] S113, determine whether the vehicle enters the OFF gear. If yes, execute step S109; if no, execute step S114.

[0076] S114, the vehicle air conditioner continues to execute according to the current state until a new instruction is issued.

[0077] S115, the vehicle is in an emergency power-off state.

[0078] S116: Do not respond to a locking signal triggered by the remote control key within a preset range for a duration reaching a preset duration.

[0079] In summary, according to the control method of the vehicle air conditioner in the embodiment of the present application, the current state of the vehicle is first obtained. When the current state of the vehicle is within the preset state set, the target parameters are obtained according to the current state of the vehicle, and when the target parameters meet the preset activation conditions, in response to the locking signal triggered by the remote control key within the preset range and the duration reaches the preset duration, the vehicle air conditioner is controlled to enter the target operation mode. Therefore, this method reuses the buttons of the car remote control key, and can realize the remote start of the vehicle air conditioner without increasing the hardware cost, thereby improving the convenience of using the vehicle air conditioner and the riding comfort of the user. At the same time, the activation judgment is made in combination with the vehicle state and the corresponding target parameters, further improving the air conditioning control accuracy and applicability.

[0080] Corresponding to the above embodiments, the present application also proposes a controller.

[0081] like Figure 4 As shown, the controller 100 of the embodiment of the present application includes a memory 110, a processor 120, and a control program for the vehicle air conditioner stored in the memory 110 and executable on the processor 120. When the processor 120 executes the control program for the vehicle air conditioner, the above-mentioned control method for the vehicle air conditioner is implemented.
