[0002] With the development of new energy vehicles, intelligent in-vehicle human-machine interaction systems (HMI) have gradually become the mainstream choice in the market. The air conditioning control function of modern cars has changed from traditional physical buttons, knobs and other operation methods to a touch screen-based HMI operation interface, which has improved the system's integration and design aesthetics.

Obviously, the described embodiments are only part of the embodiments of the present disclosure, rather than all of the embodiments.

[0049] Research has found that if the driver needs to frequently adjust air-conditioning temperature, air volume and other parameters during driving, the touch screen operation may cause distraction, thus affecting driving safety. At the same time, as one of the key factors in passenger experience, air conditioning not only needs to meet temperature adjustment needs, but also needs to provide a personalized comfort experience. Most traditional air-conditioning systems are equipped with an automatic (AUTO) mode, which controls the air outlet temperature based on a preset calibration temperature. However, due to differences in temperature sensitivity and comfort requirements among different users, the unified AUTO mode often cannot meet the personalized temperature adjustment needs of passengers, especially in extreme weather (such as high or low temperature environments). The experience effect is particularly poor.

[0050] Based on the above research, the present disclosure provides a control method, device, electronic device and storage medium for automobile air conditioning, which responds to the air conditioning mode selection operation triggered by the user, determines the target air conditioning mode corresponding to the air conditioning mode selection operation; collects the current outside temperature, determines the target air conditioning performance index preset in the target air conditioning mode corresponding to the current outside temperature; controls the operating parameters corresponding to the automobile air conditioning components according to the target air conditioning performance index until the target air conditioning performance index is met. A multi-mode air conditioning control strategy is adopted to meet the personalized needs of different passengers and improve the convenience and safety of the driver's operation.

[0051] To facilitate understanding of this embodiment, a control method for an automobile air conditioner disclosed in an embodiment of the present disclosure is first introduced in detail. The execution subject of the control method for an automobile air conditioner provided in an embodiment of the present disclosure is generally a computer device with certain computing capabilities, and the computer device includes, for example: a terminal device or a server or other processing device, and the terminal device may be a user equipment (UE), a mobile device, a user terminal, a terminal, a cellular phone, a cordless phone, a personal digital assistant (PDA), a handheld device, a computing device, a vehicle-mounted device, a wearable device, etc. In some possible implementations, the control method for an automobile air conditioner may be implemented by a processor calling a computer-readable instruction stored in a memory.

[0052] See also Figure 1 FIG. 1 is a flow chart of a method for controlling an automobile air conditioner provided by an embodiment of the present disclosure, wherein the method comprises steps S101 to S103, wherein:

[0053] S101 . In response to an air-conditioning mode selection operation triggered by a user, determining a target air-conditioning mode corresponding to the air-conditioning mode selection operation.

[0054] In specific implementation, on the HMI central control screen of the car, the air conditioning function interface includes a variety of preset air conditioning modes (for example, warm mode, fast warm mode, cool mode, fast cooling mode, and user-defined mode, etc.). The user selects a certain air conditioning mode by touch or voice control. This operation can be performed in different scenarios. For example, the user may select "fast cooling mode" because the external temperature is too high, or select "warm mode" in winter.

[0055] Here, the air conditioning mode selection module of the system monitors the user's operation on the HMI interface in real time. When the user selects a mode, the system will recognize this operation and record the selected mode as the current air conditioning mode selection. The system determines the corresponding target air conditioning mode based on the air conditioning mode selected by the user. For example, when the user selects "Quick Cooling Mode", this mode becomes the target air conditioning mode at this time.

[0056] The system will associate the target air conditioning mode with the corresponding preset mode parameters, including temperature, air volume, humidity, circulation mode, etc. Through this association, the system can further determine the specific air conditioning performance parameters of the mode under different ambient temperatures.

[0057] For example, if the user selects "Quick Warm Mode", the system will identify this selection and determine that "Quick Warm Mode" is the target air conditioning mode, and rapid heating should be given priority in this mode. When the current external temperature is low, the system will set a high air volume internal circulation according to the configuration of the Quick Warm Mode to increase the temperature inside the car as quickly as possible, thereby achieving the rapid heating effect required by the user.

[0058] S102: collecting the current vehicle exterior temperature, and determining a target air-conditioning performance index preset in the target air-conditioning mode corresponding to the current vehicle exterior temperature.

[0059] In specific implementation, the temperature sensor equipped in the vehicle will monitor the current outside temperature in real time. After the outside temperature data is collected by the sensor, it is transmitted to the car's cabin domain controller or central control unit. These control units are responsible for processing and further operations of the temperature data.

[0060] Here, each air conditioning mode is designed with corresponding performance indicators preset for different external temperature ranges. For example, the air conditioner may be set with three outside temperature ranges: low temperature (<10℃), medium temperature (10℃~25℃), and high temperature (≥25℃). After obtaining the current outside temperature, the system will compare this temperature with the preset temperature range to determine which range the current temperature belongs to. After clarifying the current outside temperature range, the system will extract the corresponding air conditioning performance indicators from the preset target air conditioning mode.

[0061] Among them, the air conditioning performance indicators include at least: target temperature indicator, target humidity indicator, target air volume indicator and target air cleanliness indicator. Target temperature indicator: set the temperature of the air outlet of the air conditioner. For example, in a high temperature environment, the system may set a lower target temperature to cool down quickly. Target humidity indicator: control the humidity in the car to achieve a comfortable level. In cold weather, the system may increase the humidity to prevent dryness. Target air volume indicator: control the air conditioning wind speed so that the target temperature can be quickly reached in different environments. The air volume is usually higher in fast cooling and fast heating modes, while the air volume is moderate in comfort mode. Air cleanliness index: determine the internal and external circulation mode and whether to turn on the air purification function based on the external air quality and passenger needs.

[0062] For example, taking the quick heating mode as an example, if the current temperature outside the car is low (such as <10℃), the system will set the target temperature to a higher value and increase the air volume to quickly heat up; in the medium temperature range (10℃~25℃), the target temperature will be appropriately lowered to achieve a more balanced warm air effect.

[0063] For example, if the user selects "Cool Mode" in hot weather, the temperature sensor detects that the outside temperature is 30°C, which is in the high temperature range. The system matches the performance indicators of the Cool Mode in the high temperature range, sets a lower target temperature (such as 18°C), a moderate air volume (such as level 3), and turns on the external circulation to ensure air circulation in the car. The system converts these performance indicators into control signals, transmits them to relevant components, and controls the outlet temperature and air volume to achieve the set target performance.

[0064] For details, see Figure 2 FIG. 1 is a flow chart of another method for controlling an automobile air conditioner provided by an embodiment of the present disclosure, wherein the method comprises steps S1021 to S103, wherein:

[0065] S1021. Generate an air-conditioning operation request carrying the target air-conditioning mode.

[0066] S1022: Control the vehicle cabin domain controller to collect the current vehicle outside temperature in response to the air conditioning operation request, and determine a target preset vehicle outside temperature range within which the current vehicle outside temperature is located.

[0067] S1023: Determine the target air-conditioning performance index corresponding to the target preset vehicle exterior temperature range in the target air-conditioning mode.

[0068] In the specific implementation, when the user selects an air conditioning mode (such as "fast heating mode" or "fast cooling mode") in the HMI, the system will generate an air conditioning work request. This request carries the information of the target air conditioning mode, instructing the system to use this mode as the operating mode of the air conditioner. The core information contained in the air conditioning work request includes the target air conditioning mode (such as fast heating mode or cool mode) and the performance requirements of the mode. For example, the request for "fast heating mode" will carry the required target temperature, humidity, air volume and other information. The generated air conditioning work request will be sent to the car cabin domain controller through the vehicle bus (such as CAN bus) so that it can start the corresponding control process.

[0069] Here, after receiving the air conditioning work request, the cockpit domain controller will first identify the target air conditioning mode in the request and confirm the outdoor temperature requirement of the mode. The cockpit domain controller sends a signal to the temperature sensor to obtain real-time outdoor temperature data. The current outdoor temperature collected by the temperature sensor will be transmitted back to the cockpit domain controller and temporarily stored inside the controller.

[0070] Among them, the air-conditioning system is divided into multiple preset intervals (such as low temperature, medium temperature, and high temperature) according to the ambient temperature. When designing each air-conditioning mode, the performance requirements corresponding to different temperature intervals have been set to adapt to different environmental conditions. After receiving the current outdoor temperature data, the cockpit domain controller will match the temperature with the preset interval. For example, if the current outdoor temperature is 5°C, the cockpit domain controller will determine that this temperature belongs to the low temperature interval. Based on the matching results of the temperature interval, the system will determine the preset interval in which the current temperature is located, and use this interval as the basis for the subsequent air-conditioning performance control.

[0071] Optionally, the vehicle cabin domain controller includes at least: a compressor controller, a left zone controller, a right zone controller, a rear zone controller and a heating controller; the vehicle air-conditioning component controlled by the compressor controller is the compressor; the vehicle air-conditioning component controlled by the left zone controller is the damper motor; the vehicle air-conditioning components controlled by the right zone controller include at least an expansion valve, a stop valve, a water pump, a blower and a solenoid valve motor; the vehicle air-conditioning component controlled by the rear zone controller is the damper motor; the vehicle air-conditioning component controlled by the heating controller is the heater.

[0072] Furthermore, after clarifying the range in which the current temperature is located, the cockpit domain controller will look for the preset performance indicators of the target air-conditioning mode in this temperature range. For example, in the low temperature range of the fast heating mode, a higher air outlet temperature and a large air volume may be set to quickly heat up. After determining the target air-conditioning performance indicators, the cockpit domain controller will generate corresponding control signals to be transmitted to the control units of various air-conditioning components, such as compressors, blowers, dampers, and heaters. These control signals set the operating parameters of each component based on the target performance indicators to ensure that the in-vehicle environment meets the requirements of the air-conditioning mode selected by the user.

[0073] For example, suppose the user selects the "fast heating mode" in winter: the system generates an air conditioning work request with the fast heating mode, indicating that the system should perform the fast heating operation under the current environment; after receiving the request, the cockpit domain controller obtains the current outside temperature, assuming it is 5°C; 5°C belongs to the low temperature range, and the system classifies this temperature into the low temperature range of the fast heating mode. The low temperature range of the fast heating mode corresponds to a higher target temperature (for example, 30°C) and a large air volume (for example, 5 gears) to quickly increase the temperature inside the car.

[0074] S103: Control operating parameters corresponding to automobile air-conditioning components according to the target air-conditioning performance index until the target air-conditioning performance index is met.

[0075] In the specific implementation, the target air conditioning performance indicators (such as target temperature, humidity, air volume, air cleanliness, etc.) first need to be parsed into specific operating parameters that each air conditioning component can perform. The system decomposes the overall target air conditioning performance indicators into sub-performance indicators that each air conditioning component (such as compressor, damper, blower, heater, etc.) needs to achieve. For example, to achieve the target in-car temperature of 25°C, the system may need to adjust the compressor speed to a certain level, and set the damper position and wind speed, etc.

[0076] Here, the current operating parameters of each air-conditioning component are first obtained, such as the current compressor speed, blower air volume, water pump flow rate, damper opening and closing status, etc. These parameters are fed back to the central control unit through sensors. In this process, these parameters are also fed back to the cockpit domain controller or vehicle domain controller.

[0077] Specifically, the current operating parameters are compared with the target operating parameters to calculate the difference. For example, if the current temperature is lower than the target temperature, the heater power or the blower air volume needs to be increased. Based on the calculation results, specific control parameters for each component are generated. For example, in the rapid cooling mode, if the temperature needs to be further reduced, the system will increase the compressor speed and adjust the damper to control the air flow direction.

[0078] Among them, the control parameters generated by the system will be sent to the control units of related air-conditioning components, such as compressor controllers, damper controllers, and heater controllers. These signals are usually transmitted through an on-board bus (such as a CAN bus or a LIN bus) to achieve remote control of the components. After receiving the control parameters, the control unit of each component adjusts its own working state. For example, the blower control unit will increase the air volume to level 5 to quickly reduce the temperature, while the compressor controller will increase the compressor speed to increase the cooling effect.

[0079] As a possible implementation method, the following steps 1 to 4 are used to control the operating parameters corresponding to the automobile air-conditioning components to meet the target air-conditioning performance indicators:

[0080] Step 1: parsing the target air conditioning performance index into multiple sub-performance indexes.

[0081] Step 2: Obtain current component operating parameters corresponding to each of the automobile air-conditioning components in the automobile air-conditioning.

[0082] Step 3, step 1, generating the target operating condition control parameters corresponding to the automobile air conditioning component according to the current component operating condition parameters and the corresponding sub-performance indicators.

[0083] Step 4: According to the target operating condition control parameters, control the automobile air conditioning components to operate according to the corresponding sub-performance indicators.

[0084] In the specific implementation, in the air conditioning mode, each mode (such as fast heating mode, fast cooling mode, cool mode, etc.) presets specific performance requirements, which include overall performance targets such as temperature, humidity, and air volume. In order to apply these overall targets to specific air conditioning components, the target air conditioning performance indicators are first decomposed into various sub-performance indicators. Each sub-performance indicator is a specific value or state setting that is directly related to the actual operation of the air conditioning component.

[0085] For example, the target temperature index can be converted into the temperature setting of the compressor and PTC heater and the opening of the damper. The target humidity index can be controlled by the internal / external circulation mode of the compressor and the air conditioner. The target air volume index is directly related to the wind speed setting of the blower. After such decomposition, each sub-performance index is directly associated with the working state of one or more air conditioning components, which facilitates the control of each component separately to achieve the overall target performance.

[0086] Here, the current operating parameters of each air-conditioning component are obtained through sensors and feedback mechanisms, and the status of each component is understood in real time to determine the gap between them and the target state. The air-conditioning components can mainly include: compressor, blower, damper, PTC heater, water pump, solenoid valve, etc. The operating parameters corresponding to the compressor can include the current speed or power; the operating parameters corresponding to the blower can include the current wind speed registration (such as 0-5 gears); the operating parameters corresponding to the damper can include the current opening status of the cold and warm air damper, mode damper, and internal / external circulation damper; the operating parameters corresponding to the PTC heater can include the current power output; the operating parameters corresponding to the water pump, solenoid valve, etc. can include the flow rate of the water pump and the opening and closing status of the solenoid valve.

[0087] Among them, the current operating parameters and the corresponding sub-performance indicators are compared to determine the adjustment direction and amplitude of each component. For example, if the current temperature is lower than the target temperature, the system will increase the heater power or increase the wind speed. Based on the difference, the system calculates and generates the target operating control parameters. For example, if a stronger cooling effect is required, the system will increase the target speed of the compressor; if a larger air volume is required to speed up the temperature adjustment in the car, the system will set the air volume to 5 gears; according to the mode requirements, such as internal circulation (to increase the speed of temperature change in the car) or external circulation (to maintain air circulation), adjust the opening of the damper. Finally, the system converts the calculated control parameters into control signals and sends them to the control units of each air-conditioning component in the form of instructions.

[0088] Furthermore, the control signal is transmitted to the control unit of the air-conditioning component through in-vehicle networks such as the CAN bus and LIN bus. The controller of each component adjusts its own working state according to the received signal. Each component performs corresponding operations according to the control signal, making the operating condition parameters gradually approach the sub-performance indicators. For example: gradually increasing the blower air volume to meet the target wind speed setting; increasing or decreasing the compressor speed to achieve the cooling or heating effect; adjusting the opening degree of the air damper according to the system instruction to ensure that the air circulation meets the set requirements.

[0089] Exemplarily, assume that the user selects the "Quick Warm Mode" in low-temperature weather, and the target performance indicators are: target temperature 25°C, air volume at level 5, and internal circulation. Decompose the target temperature of 25°C, air volume at level 5, and internal circulation into specific control parameters such as the target temperature of the compressor, the power of the PTC heater, the blower wind speed, and the air damper position. Obtain the current temperature (20°C), wind speed (level 3), and air damper (external circulation). Generate control parameters according to the difference, set the power of the PTC heater to a higher output, adjust the air volume to level 5, and switch the air damper to the internal circulation position. Send a control signal to start the PTC heater, increase the blower wind speed, and switch the air damper. Monitor the feedback in real time. If the temperature reaches 25°C, the system will maintain the current state until adjustment is required again.

[0090] Next, the above solution will be described in conjunction with specific embodiments.

[0091] The selection of the air-conditioning mode is added to the air-conditioning interface of the HMI central control screen. The air-conditioning modes are designed as: Warm Mode, Quick Warm Mode, Cool Mode, Quick Cool Mode, Custom Mode 1, 2, 3 (defined according to the passengers' habits), and three temperature ranges are set, including Tout≥25°C, 10<Tout<25°C, Tout<10°C (Tout represents the outdoor temperature). In the Warm Mode, Quick Heat Mode, Cool Mode, and Quick Cool Mode, the temperature at the passenger compartment air outlet decreases as the outdoor temperature rises. When Tout<10°C, the outlet air temperature is the highest. When 10<Tout<25°C compared with Tout<10°C, the outlet air temperature drops by 2°C. When Tout≥25°C compared with 10<Tout<25°C, the outlet air temperature drops by 2°C. In the Quick Heat Mode and Quick Cool Mode, the external circulation is turned on by default, and the internal circulation is the default. In the Warm Mode and Cool Mode, it is designed to be the external circulation by default to ensure the fresh air intake in the passenger compartment.

[0092] The automotive electronic and electrical architecture is domain-integrated, including vehicle domain controller + left zone controller + right zone controller + rear zone controller, namely VDC (Vehicle Domain Controller) + Left ZCU (Zonal Control Unit) + Right ZCU + Rear ZCU, where VDC implements the logic algorithm part of vehicle thermal management; ZCU implements the collection of sensor signals in vehicle thermal management and the driving part of actuators such as motors.

[0093] The HMI central control screen obtains the air conditioning mode selected by the driver or passenger and sends it to the cockpit domain controller. The cockpit domain controller identifies the target performance indicators corresponding to the target air conditioning mode and sends them to the vehicle domain controller VDC through the CAN bus. The target performance indicators corresponding to the target air conditioning mode are: target temperature indicator, target humidity indicator, target air volume indicator, and target air cleanliness indicator;

Each controller chooses to switch its current performance indicator directly to the corresponding target performance indicator based on its currently acquired relevant status parameters to achieve air conditioning mode switching control.

[0095] Among them, the signals that the left domain of ZCU obtains from VDC are: mode damper, heating and cooling damper, internal and external circulation damper motor PWM control signals; the signals that the right domain of ZCU obtains from VDC are: expansion valve PWM control signal, solenoid valve control signal, water pump PWM control signal, blower PWM control signal; the signals that the back domain of ZCU obtains from VDC are: mode damper, heating and cooling damper motor PWM control signal; the signals that the compressor controller obtains from VDC are: compressor PWM speed control signal; the signals that the PTC controller obtains from VDC are: PTC PWM power control signal.
