Description

TECHNICAL FIELD

[0001] The present disclosure relates to the technical field of automobiles, and in particular, to a control method and device for an automobile air conditioner, an electronic device, and a storage medium. BACKGROUND

[0002] With the development of new energy vehicles, intelligent vehicle-mounted human-machine interaction systems (HMI) have gradually become the mainstream choice in the market. The control function of the air conditioner of a modern vehicle has changed from the traditional physical buttons, knobs, and other operation modes to an HMI operation interface based on a touch screen, thereby improving the integration and design aesthetics of the system. However, this operation mode has potential safety hazards during high-speed driving. If the driver needs to frequently adjust the air conditioner temperature, air volume, and other parameters during driving, the driver's attention may be distracted due to the touch screen operation, thereby affecting driving safety.

[0003] At the same time, as one of the key factors for passenger experience, the air conditioner needs to not only meet the temperature regulation requirements but also provide personalized comfort experience. Most traditional air conditioning systems are equipped with an AUTO mode that controls the outlet air temperature based on a preset calibration temperature. However, due to differences in temperature sensitivity and comfort requirements of different users, a unified AUTO mode often cannot meet the personalized temperature regulation requirements of passengers, especially in extreme weather conditions (such as high-temperature or low-temperature environments).

[0046] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this disclosure, and not all of them. The components of the embodiments of this disclosure described and shown in the accompanying drawings can generally be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this disclosure provided in the accompanying drawings is not intended to limit the scope of the claimed disclosure, but merely represents selected embodiments of this disclosure. All other embodiments obtained by those skilled in the art based on the embodiments of this disclosure without inventive effort are within the scope of protection of this disclosure.

[0047] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0048] In this document, the term "and / or" merely describes a relationship, indicating that three relationships can exist. For example, A and / or B can represent three cases: A alone, A and B simultaneously, and B alone. Furthermore, the term "at least one" in this document means any combination of at least two of any one or more elements. For example, including at least one of A, B, and C can mean including any one or more elements selected from the set consisting of A, B, and C.

[0049] Research has found that drivers who frequently need to adjust air conditioning parameters such as temperature and fan speed while driving may experience distraction due to touchscreen operation, thus affecting driving safety. Furthermore, air conditioning, as a key factor in passenger experience, needs to not only meet temperature control requirements but also provide a personalized comfort experience. Traditional air conditioning systems are mostly equipped with an automatic (AUTO) mode, controlling the airflow temperature based on a preset calibrated temperature. However, because different users have varying sensitivities to temperature and comfort needs, a uniform AUTO mode often fails to meet passengers' personalized temperature control needs, especially in extreme weather conditions (such as high or low temperatures), where the experience is particularly poor.

[0050] Based on the above research, this disclosure provides a control method, device, electronic device, and storage medium for automotive air conditioning. In response to a user-triggered air conditioning mode selection operation, it determines the target air conditioning mode corresponding to the operation; collects the current outside temperature and determines a preset target air conditioning performance index corresponding to the current outside temperature within the target air conditioning mode; and controls the operating parameters of the automotive air conditioning components according to the target air conditioning performance index until the target air conditioning performance index is met. This multi-mode air conditioning control strategy meets the personalized needs of different passengers and improves the convenience and safety of driver operation.

[0051] To facilitate understanding of this embodiment, a detailed description of a vehicle air conditioning control method disclosed in this disclosure is provided first. The execution entity of the vehicle air conditioning control method provided in this disclosure is generally a computer device with certain computing capabilities. This computer device may include, for example, a terminal device, a server, or other processing devices. The terminal device may be a user equipment (UE), mobile device, user terminal, terminal, cellular phone, cordless phone, personal digital assistant (PDA), handheld device, computing device, in-vehicle device, wearable device, etc. In some possible implementations, the vehicle air conditioning control method can be implemented by a processor calling computer-readable instructions stored in memory.

[0052] See Figure 1 The diagram shows a flowchart of a method for controlling an automotive air conditioner according to an embodiment of this disclosure. The method includes steps S101 to S103, wherein:

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

[0054] In practice, the car's HMI (Hybrid Management Interface) screen displays various preset air conditioning modes (e.g., warm mode, quick warm mode, cool mode, quick cool mode, and user-defined modes). Users select a mode via touch or voice control. This operation can be performed in different scenarios; for example, a user might select "quick cool mode" due to high outside temperatures or "warm mode" in winter.

[0055] Here, the system's air conditioning mode selection module monitors the user's operations on the HMI interface in real time. When the user selects a mode, the system recognizes this operation and records the selected mode as the current air conditioning mode selection. Based on the air conditioning mode selected by the user, the system determines the corresponding target air conditioning mode. For example, when the user selects "Quick Cooling Mode," this mode becomes the target air conditioning mode at that moment.

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

[0057] For example, assuming the user selects "Quick Heating Mode," the system recognizes this selection and determines "Quick Heating Mode" as the target air conditioning mode, prioritizing rapid heating. When the outside temperature is low, the system will set a high airflow for internal circulation based on the Quick Heating Mode configuration to quickly raise the interior temperature, thus achieving the user's desired rapid heating effect.

[0058] S102. Collect the current outside temperature and determine the target air conditioning performance index preset in the target air conditioning mode corresponding to the current outside temperature.

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

[0060] Here, each air conditioning mode is designed with pre-set performance indicators for different external temperature ranges. For example, the air conditioning might be set to three outside temperature ranges: low (<10°C), medium (10°C~25°C), and high (≥25°C). After obtaining the current outside temperature, the system compares this temperature with the pre-set temperature ranges to determine which range the current temperature belongs to. Once the current outside temperature range is determined, the system extracts the corresponding air conditioning performance indicators from the pre-set target air conditioning mode.

[0061] The air conditioning performance indicators include at least the following: target temperature, target humidity, target airflow, and target air cleanliness. Target temperature: This sets the temperature at the air vents. For example, in high-temperature environments, the system may set a lower target temperature for rapid cooling. Target humidity: This controls the humidity inside the vehicle to achieve a comfortable level. In cold weather, the system may increase the humidity to prevent dryness. Target airflow: This controls the air conditioning fan speed to quickly reach the target temperature in different environments. The airflow is typically higher in rapid cooling and heating modes, while moderate in comfort mode. Air cleanliness: Based on external air quality and passenger needs, this determines the internal / external air circulation mode and whether the air purification function is activated.

[0062] For example, in the quick-heating mode, if the current outside temperature is low (e.g., <10°C), the system will set the target temperature to a higher value and increase the airflow to heat up quickly; while in the medium temperature range (10°C~25°C), the target temperature will be appropriately lowered to achieve a more balanced heating effect.

[0063] For example, suppose a user selects "Cool Mode" in hot weather. The temperature sensor detects an outside temperature of 30°C, which is within the high-temperature range. The system matches the performance indicators of Cool Mode in the high-temperature range, sets a lower target temperature (e.g., 18°C), a moderate airflow (e.g., level 3), and activates the external air circulation to ensure airflow inside the vehicle. The system converts these performance indicators into control signals, transmits them to relevant components, and controls the air outlet temperature and airflow to achieve the set target performance.

[0064] For details, see Figure 2 The diagram shows a flowchart of another automotive air conditioning control method provided in this disclosure, the method including steps S1021-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 outside temperature in response to the air conditioning operation request, and determine the target preset outside temperature range in which the current outside temperature is located.

[0067] S1023. Determine the target air conditioning performance index corresponding to the target preset outside temperature range under the target air conditioning mode.

[0068] In practice, when a user selects an air conditioning mode (such as "Quick Heating" or "Quick Cooling") in the HMI, the system generates an air conditioning operation request. This request carries information about the target air conditioning mode, instructing the system to use that mode as the air conditioning's operating mode. The core information contained in the air conditioning operation request includes the target air conditioning mode (such as Quick Heating or Cooling) and the performance requirements of that mode. For example, a "Quick Heating" request would carry information such as the required target temperature, humidity, and airflow. The generated air conditioning operation request is sent to the vehicle's cockpit domain controller via the vehicle bus (such as the CAN bus) so that it can initiate the corresponding control process.

[0069] Here, after receiving an air conditioning operation request, the cockpit domain controller first identifies the target air conditioning mode in the request and confirms the mode's requirement for outside temperature. The cockpit domain controller then sends a signal to the temperature sensor to obtain real-time outside temperature data. The current outside temperature collected by the temperature sensor is transmitted back to the cockpit domain controller and temporarily stored within the controller.

[0070] The air conditioning system is divided into multiple preset temperature zones (such as low, medium, and high). Each air conditioning mode is designed with specific performance requirements for different temperature zones to adapt to various environmental conditions. Upon receiving the current outside temperature data, the cabin domain controller matches this temperature with the preset zones. For example, if the current outside temperature is 5°C, the cabin domain controller will determine that this temperature belongs to the low temperature zone. Based on the temperature zone matching result, the system determines the preset zone in which the current temperature falls and uses this zone as the basis for 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 compressor controller controls the vehicle air conditioning component of a compressor; the left zone controller controls the vehicle air conditioning component of a damper motor; the right zone controller controls the vehicle air conditioning component of at least an expansion valve, a shut-off valve, a water pump, a blower, and a solenoid valve motor; the rear zone controller controls the vehicle air conditioning component of a damper motor; and the heating controller controls the vehicle air conditioning component of a heater.

[0072] Furthermore, after identifying the current temperature range, the cabin domain controller will look up the preset performance indicators for the target air conditioning mode within that temperature range. For example, in the low-temperature range of the quick-heat mode, a higher outlet air temperature and a larger airflow might be set to quickly raise the temperature. After determining the target air conditioning performance indicators, the cabin domain controller will generate corresponding control signals to transmit to the control units of various air conditioning components, such as the compressor, blower, 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 a user selects "Quick Heating Mode" in winter: The system generates an air conditioning operation request carrying the Quick Heating Mode, instructing the system to perform quick heating operation in the current environment; after receiving the request, the cabin domain controller obtains the current outside temperature, let's say 5°C; 5°C is in the low-temperature range, and the system classifies this temperature into the low-temperature range of Quick Heating Mode. The low-temperature range of Quick Heating Mode corresponds to a higher target temperature (e.g., 30°C) and a high airflow (e.g., level 5) to quickly raise the interior temperature.

[0074] S103. Control the operating parameters of the vehicle air conditioning components according to the target air conditioning performance index until the target air conditioning performance index is met.

[0075] In practical implementation, the target air conditioning performance indicators (such as target temperature, humidity, air volume, air cleanliness, etc.) first need to be analyzed 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 a target interior temperature of 25°C, the system may need to adjust the compressor speed to a certain level, while simultaneously setting the damper position and fan speed, etc.

[0076] Here, the current operating parameters of each air conditioning component are first acquired, such as the current compressor speed, blower airflow, water pump flow rate, and damper opening / closing status. These parameters are then fed back to the central control unit via sensors. During this process, these parameters are also fed back to the cabin domain controller or the vehicle domain controller.

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

[0078] The system generates control parameters which are then sent to the control units of relevant air conditioning components, such as the compressor controller, damper controller, and heater controller. These signals are typically transmitted via vehicle bus (such as CAN bus or LIN bus) to enable remote control of the components. Upon receiving the control parameters, each component's control unit adjusts its operating status. For example, the blower control unit might increase the airflow to level 5 to quickly lower the temperature, while the compressor controller might increase the compressor speed to enhance cooling efficiency.

[0079] As one possible implementation method, the operating parameters of the automotive air conditioning components are controlled to meet the target air conditioning performance indicators through the following steps 1-4:

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

[0081] Step 2: Obtain the current component operating parameters for each type of automotive air conditioning component.

[0082] Step 3, Step 1: Generate the target operating condition control parameters for the automotive air conditioning component based on the current component operating condition parameters and the corresponding sub-performance indicators.

[0083] Step 4: Control the automotive air conditioning components to operate according to the corresponding sub-performance indicators based on the target operating condition control parameters.

[0084] In practical implementation, each air conditioning mode (such as rapid heating mode, rapid cooling mode, and cool mode) has preset specific performance requirements, including overall performance targets such as temperature, humidity, and airflow. To apply these overall targets to specific air conditioning components, the target air conditioning performance indicators are first decomposed into individual 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 can be converted into the temperature settings of the compressor and PTC heater, and the opening of the dampers. The target humidity can be controlled by the compressor and the internal / external circulation mode of the air conditioner. The target air volume is directly related to the blower speed setting. After this decomposition, each sub-performance indicator is directly associated with the operating status of one or more air conditioning components, facilitating individual control of each component to achieve the overall target performance.

[0086] Here, sensors and feedback mechanisms are used to acquire the current operating parameters of each air conditioning component, allowing for real-time monitoring of each component's status and assessment of its differences from the target state. The air conditioning components mainly include: compressor, blower, dampers, PTC heater, water pump, and solenoid valves. Operating parameters for the compressor can include the current speed or power; for the blower, they can include the current fan speed (e.g., 0-5); for the dampers, they can include the current opening status of the heating / cooling damper, mode damper, and internal / external circulation damper; for the PTC heater, they can include the current power output; and for the water pump and solenoid valves, they can include the water pump flow rate and the solenoid valve's open / closed status.

[0087] The system compares current operating parameters with corresponding sub-performance indicators to determine the adjustment direction and magnitude for each component. For example, if the current temperature is lower than the target temperature, the system will increase the heater power or increase the fan speed. Based on the difference, the system calculates and generates target operating condition control parameters. For instance, if a stronger cooling effect is needed, the system will increase the target compressor speed; if a larger airflow is needed to accelerate the adjustment of the vehicle's interior temperature, the system will set the fan speed to level 5; and depending on the mode requirement, such as recirculation (to increase the speed of temperature change inside the vehicle) or external circulation (to maintain air circulation), the system will adjust the vent opening. Finally, the system converts the calculated control parameters into control signals and sends them as instructions to the control units of each air conditioning component.

[0088] Further, 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 working 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 differences, 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 the 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 readjustment is needed.

[0090] Next, the above solution will be described in combination 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 Warm Mode, Cool Mode, and Quick Cool Mode, the temperature at the outlet of the passenger compartment decreases as the outdoor temperature increases. 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 Warm 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, the external circulation is designed as the default to ensure the intake of fresh air in the passenger compartment.

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

[0093] After obtaining the air conditioning mode selected by the driver or passenger, the HMI central control screen sends it to the cabin domain controller. The cabin domain controller identifies the target performance indicators corresponding to the target air conditioning mode and sends them to the vehicle domain controller (VDC) via the CAN bus. The target performance indicators corresponding to the target air conditioning mode are: target temperature, target humidity, target airflow, and target air cleanliness.

[0094] The Vehicle Domain Controller (VDC), based on the vehicle's current operating parameters, uses logic algorithms to break down each target performance indicator into control signals for the water pump, blower motor, compressor speed, air conditioning unit's heating / cooling damper, internal / external circulation damper, mode damper, PTC heater, solenoid valve, and negative ion generator, etc. These signals are then sent via the CAN bus to the Left Zone Controller (Left ZCU), Right Zone Controller (Right ZCU), Rear Zone Controller (Rear ZCU), and compressor controller, and via the LIN bus to the PTC controller. Each controller, based on its acquired status parameters, selects to directly switch its current performance indicator to the corresponding target performance indicator, thus achieving air conditioning mode switching control.

[0095] Specifically, the left domain of the ZCU acquires the following VDC signals: PWM control signals for the mode damper, heating / cooling damper, and internal / external circulation damper motors; the right domain of the ZCU acquires the following VDC signals: PWM control signals for the expansion valve, solenoid valve, water pump, and blower; the rear domain of the ZCU acquires the following VDC signals: PWM control signals for the mode damper and heating / cooling damper motors; the compressor controller acquires the following VDC signals: PWM speed control signals for the compressor; and the PTC controller acquires the following VDC signals: PWM power control signals for the PTC.

[0096] This disclosure provides a method for controlling an automotive air conditioning system. In response to a user-triggered air conditioning mode selection operation, the method determines a target air conditioning mode corresponding to the selection operation; collects the current outside temperature and determines a preset target air conditioning performance index corresponding to the current outside temperature within the target air conditioning mode; and controls the operating parameters of the automotive air conditioning components according to the target air conditioning performance index until the target air conditioning performance index is met. This multi-mode air conditioning control strategy meets the personalized needs of different passengers and improves the convenience and safety of driver operation.

[0097] Those skilled in the art will understand that, in the above-described method of the specific implementation, the order in which each step is written does not imply a strict execution order and does not constitute any limitation on the implementation process. The specific execution order of each step should be determined by its function and possible internal logic.

Since the principle of the device in this disclosure for solving the problem is similar to the control method for an automotive air conditioner described above, the implementation of the device can refer to the implementation of the method, and the repeated parts will not be described again.
