[0033] Embodiments of the present application are described in detail below with reference to the accompanying drawings, in which the same or similar notations used throughout the drawings and the specific description denote 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 explain the present application, and cannot be understood as limiting the present application.

[0034] The control method, controller, computer readable storage medium, control device of the vehicle air conditioner and vehicle according to the embodiments of the present application are described below with reference to the accompanying drawings.

[0035] In the related art, the user needs to enter the vehicle first to start the vehicle, and then starts the air conditioner through the knob or the vehicle-mounted electronic screen, which causes the temperature in the vehicle to reach a comfortable effect after the user enters the vehicle for a period of time, reducing the passenger comfort.

[0036] To solve the above technical problems, the present application provides a control method of a vehicle air conditioner, which reuses the lock button of the remote key, remotely controls the vehicle air conditioner without increasing hardware costs, and can start the air conditioner in advance to adjust the temperature in the vehicle and improve the driving comfort of people when the user has not yet entered the vehicle. The control method of the vehicle air conditioner according to the present application is described in detail below with reference to the accompanying drawings.

[0037] Figure 1 Flowchart of the control method of the vehicle air conditioner according to an embodiment of the present application.

[0038] As shown in Figure 1 the control method of the vehicle air conditioner according to an embodiment of the present application comprises:

[0039] S1, obtaining the current state of the vehicle;

[0040] S2, in the case that the current state of the vehicle is in the preset state set, obtaining the target parameter according to the current state of the vehicle;

[0041] S3, in the case that the target parameter meets the preset activation condition, controlling the vehicle air conditioner to enter the target operation mode in response to the lock signal triggered by the remote key within the preset range for a duration reaching the preset duration.

[0042] Specifically, the current state of the vehicle can be woken up to obtain after receiving the lock button trigger signal of the remote 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 a running state allowing the vehicle to wake up and start the air conditioner based on the lock signal, which is specifically set according to actual conditions. In the case that the current state of the vehicle is in the preset state set, it is considered that the current vehicle state allows remote wake-up and start of the vehicle-mounted 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 condition for starting the vehicle-mounted air conditioner. For example, when the vehicle is in a parked power-off state, the power of the energy storage battery and the state of the power supply path can be used as target parameters; when the vehicle is in a power-on state, the state of the power supply path can be used as a target parameter. Specifically, a mapping relationship between the preset state set and the target parameter of each target state in the preset state set can be established in advance, so as to determine the target parameter based on the mapping relationship according to the current state of the vehicle. In addition, the preset state set, the mapping relationship between the target parameter of each target state in the preset state set, and the vehicle identifier, the user's demand (such as age, gender, etc.) can be customized to meet the use habits of different users and the performance requirements of different vehicles.

[0044] The target parameter is obtained according to the current state of the vehicle, and then the obtained target parameter is compared with the preset activation condition. If the target parameter meets the preset activation condition, it is determined that the vehicle allows the vehicle-mounted air conditioner to be powered on and started. When the remote key is within the preset range and the duration of the lock signal reaches the preset duration, the vehicle-mounted air conditioner is controlled to start and enter the target running mode. If the target parameter does not meet the preset activation condition, it is determined that the vehicle does not allow the vehicle-mounted air conditioner to be powered on and started, and the current state of the vehicle-mounted air conditioner remains unchanged. 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 running condition.

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

[0046] The target operation mode can be defined according to user characteristics to meet different user body comfort, specifically, the user characteristics can be obtained through vehicle owner information input, including gender, age, custom characteristics, etc., for example, when the user is a female, the temperature of the target operation mode is set to 26 DEG C, and when the user is a male, the temperature of the target operation mode is set to 25.5 DEG C. The operation parameters of the target operation mode can be adjusted in combination with the current environment information to adjust the adjustment rate of the vehicle interior environment, for example, when the vehicle interior environment 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 vehicle interior environment 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 vehicle interior cooling; when the vehicle interior environment 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 vehicle interior heating. 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 parameters is less than 30%, the air speed of the vehicle-mounted air conditioner can be lowered to reduce energy consumption and avoid excessive discharge; when the battery power in the target parameters is greater than or equal to 30%, the vehicle-mounted air conditioner can be operated according to the set air speed; when the battery power in the target parameters is greater than 50%, the air speed can be adjusted based on the actual situation.

[0047] Therefore, the embodiment evaluates the vehicle performance through the current state of the vehicle and the target parameters to ensure the stability of the remote power-on of the vehicle-mounted 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 condition, the remote start signal is responded to, and the vehicle-mounted air conditioner is controlled, so that the vehicle-mounted air conditioner can be started in advance to improve the riding comfort. At the same time, the activation judgment is combined with the vehicle state and the corresponding target parameters to improve the starting control accuracy of the air conditioner, so that the air conditioner control matches the current vehicle performance to ensure the applicability of the starting control of the vehicle-mounted air conditioner on the current vehicle. Based on the control method, the user can use the remote key to issue instructions, and the control system inside the vehicle receives the instructions and processes accordingly to drive the air conditioning system to perform the corresponding actions.

[0048] In an embodiment of the present application, the vehicle includes a storage battery, the storage battery supplies power to the vehicle-mounted air conditioner through a direct current converter, the preset state set includes a key power gear closed state and a key power gear open state, and the target parameters are obtained according to the current state of the vehicle in the case that the current state of the vehicle is within the preset state set, including: when the vehicle is in the key power gear closed state, the remaining power of the storage battery, the working state of the direct current converter and the voltage of the storage battery are obtained; when the vehicle is in the key power gear open state, the working state of the direct current converter and the voltage of the storage battery are obtained.

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

[0050] In an embodiment of the present application, when the vehicle is in the key power gear off state, the target parameters are determined to meet the preset activation condition when the remaining capacity of the battery is greater than a preset capacity threshold, the DC converter is in a working state and the voltage of the battery is greater than a preset voltage; when the vehicle is in the key power gear on state, the target parameters are determined to meet the preset activation condition when the DC converter is in a working state and the voltage of the battery is greater than a preset voltage. The preset capacity threshold and the preset voltage can be set according to actual conditions.

[0051] Specifically, assuming that the preset capacity 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 key power gear = OFF, SOC (State Of Charge, remaining capacity) is greater than 20%, the DC converter is in a 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 key power gear = ON, the DC converter is in a working state and the battery voltage is greater than 12.5V.

[0052] If the trigger action is received, that is, the user long-presses the "lock" hard button of the remote key within a certain range of the vehicle, the vehicle-mounted air conditioner can be started.

[0053] In an embodiment of the present application, the vehicle-mounted air conditioner is controlled to enter the target operating mode, including: controlling the vehicle-mounted air conditioner to enter an automatic mode, and the target temperature of the vehicle-mounted air conditioner is set to a preset temperature. The preset temperature can be set according to actual conditions.

[0054] Specifically, taking 26℃ as the preset temperature, when the user starts the vehicle-mounted air conditioner by long-pressing the "lock" hard button of the remote key, the vehicle-mounted air conditioner automatically enters the AUTO (Automatic) gear, and the temperature is set to 26℃. The preset temperature can be automatically adjusted according to the current ambient temperature and the current temperature in the vehicle to quickly reach a comfortable temperature in the vehicle.

[0055] In an embodiment of the present application, when the vehicle is in the key power supply gear closed state, in response to the lock signal of the remote key triggering in the preset range for a duration reaching a preset duration, after the vehicle-mounted air conditioner is controlled to enter the target operation mode, the control method of the vehicle-mounted air conditioner further comprises: when the operation duration of the vehicle-mounted air conditioner is greater than a preset operation duration and the vehicle is in the key power supply gear closed state, controlling the vehicle-mounted air conditioner to stop; when the operation duration of the vehicle-mounted air conditioner is less than or equal to the preset operation duration and the vehicle enters the key power supply gear open state from the key power supply gear closed state, controlling the vehicle-mounted air conditioner to continue operating in the target operation mode; when the vehicle is in the key power supply gear open state, in response to the lock signal of the remote key triggering in the preset range for a duration reaching a preset duration, after the vehicle-mounted air conditioner is controlled to enter the target operation mode, the control method of the vehicle-mounted air conditioner further comprises: when the vehicle enters the key power supply gear closed state from the key power supply gear open state, controlling the vehicle-mounted air conditioner to stop. The preset operation duration can be set according to actual conditions.

[0056] Specifically, taking 15 minutes as the preset operation duration for example. If the vehicle-mounted air conditioner is started based on the above method when the vehicle is in the key power supply gear closed state, and the operation duration of the vehicle-mounted air conditioner is timed, if the vehicle has not entered the ON gear, i.e. the key power supply gear open state, when the operation duration of the vehicle-mounted air conditioner exceeds 15 minutes, the vehicle-mounted air conditioner is automatically turned off; if the vehicle enters the ON gear from the OFF gear when the operation duration of the vehicle-mounted air conditioner is less than or equal to 15 minutes, the vehicle-mounted air conditioner continues to execute according to the current state until a new instruction is issued, and the timing is reset and cancelled. At the same time, when the vehicle is in the key power supply gear closed state and the vehicle-mounted air conditioner is started based on the above method, the left and right turn signals can be controlled to flash twice for control feedback reminder. If the vehicle-mounted air conditioner is started based on the above method when the vehicle is in the key power supply gear open state, if the key power supply gear is changed from ON to OFF, the vehicle-mounted air conditioner is directly turned off.

[0057] That is, when the air conditioning function is activated, the air conditioning function can be exited when any of the following conditions occurs: the user long-presses the remote key "lock" hard button (within a certain range of the vehicle); the user clicks the large-screen air conditioner off soft button; the SOC is less than or equal to 20% in the OFF gear; the battery voltage is less than or equal to 12.5V; the high-voltage enable flag; the air conditioner works for more than 15 minutes in the OFF gear.

[0058] In an embodiment of the present application, in the case that the vehicle is in an emergency power-off state, the lock signal of the remote key triggering in the preset range for a duration reaching a preset duration is not responded.

[0059] That is, the vehicle failure strategy and processing mechanism are set, and the remote key request to start the air conditioner is not responded during the emergency power-off of the vehicle.

[0060] As a specific embodiment of the present application, the system architecture of a vehicle can be as shown in Figure 2 RKE (Remote Keyless Entry) is a system that controls the vehicle door lock and engine start through wireless signals, including a remote controller (remote key) held by the vehicle owner for sending instructions to open the lock, lock the vehicle, and start the engine, and a receiver installed on the vehicle for receiving and processing the instructions. RFR (Radio Frequency Receiver) is the core element in the PEPS (Passive Entry Passive Start) system, responsible for receiving the high-frequency unlock signal of the Bluetooth key, and then transmitting the signal to the vehicle lock module to unlock the vehicle door. In this control method, the RFR receives the on / off air conditioning request sent by the remote key and sends it to the CEM (Body Control Module), which 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, and then implements effective control and management of the battery system, maximizes the performance advantages of the battery, effectively prolongs the service life of the battery, and ensures the safety of the battery during use. CMDC (Charge Module & DCDC Converter) is responsible for converting alternating current into direct current to charge the battery of the electric vehicle, 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 whole vehicle. TMM (Temperature Management Module) is a system used to manage the temperature inside the vehicle, mainly realizing the switching of three operating areas of engine warm-up, target temperature control area and post-shutdown cooling control. Through sensor technology and automatic control algorithm, it monitors and adjusts the temperature of the vehicle to ensure that the engine and other key components operate within the optimal working temperature range, thereby improving fuel efficiency and driving experience. EAC (Electronic Acceleration Controller) optimizes the signal of the accelerator pedal sensor to improve the response performance of the engine, thereby enhancing the acceleration ability and driving experience of the vehicle. Water heating PTC (Positive Temperature Coefficient) heater is mainly used for preheating and heating of the cab or engine of the vehicle. 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 blower through the hot core, thereby realizing the heating function of the cab. Negative ion generator is a device that can generate a large number of negative ions, installed in the interior of the vehicle, mainly used to improve the air quality in the vehicle and improve the health and comfort of the driver and passengers. Negative ion generator can effectively remove harmful gases, bacteria and viruses in the vehicle by releasing negative ions, and also improve air quality and improve the mental state and health of the driver. Chiller (battery cooler) electronic valve is mainly used to introduce refrigerant in the air conditioning system, evaporate after throttling in the expansion valve, 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 of the ignition coil to ensure that the engine can start and run normally.

Therefore, the method multiplexes the keys of the car remote key, and can realize remote starting of the vehicle-mounted air conditioner without increasing the hardware cost, improves the use convenience and user riding comfort of the vehicle-mounted air conditioner, and further improves the air conditioner control accuracy and applicability by combining the vehicle state and the corresponding target parameter for activation judgment.
