[0001] The present disclosure relates to the technical field of vehicle air conditioning, and in particular to a control method, a control device, a storage medium, and an electronic device for a vehicle air conditioning. Background Art

[0002] A vehicle's air conditioning system typically accounts for a significant portion of its electrical energy consumption, especially in electric vehicles. This energy consumption significantly impacts range. Current vehicle air conditioning systems typically rely solely on whether the air conditioning system's economy mode is enabled to control energy-saving controls (e.g., the compressor, blower, and other system components). This approach is inaccurate in identifying user needs for energy conservation and comfort, potentially leading to high energy consumption and range anxiety.

[0003] Summary of the Invention

[0008] Furthermore, when the heat load demand level is the second level, controlling the operation of predetermined components in the air conditioner based on the heat load demand level further includes: obtaining the relative humidity of the air in the vehicle; and controlling and adjusting the internal and external circulation dampers based on the relative humidity of the air.

[0009] Furthermore, when the vehicle is in the non-economic mode and the air conditioning automatic circulation mode is on, the heat load level is the fourth level. When the heat load level is the fourth level, controlling the operation of predetermined components in the air conditioning based on the heat load level includes: obtaining the relative humidity of the air in the vehicle; and controlling and adjusting the movement direction of the internal and external circulation dampers based on the relative humidity of the air.

Therefore, the specific structural and functional details claimed herein are not intended to be limiting, but rather serve merely as a basis and representative basis for teaching those skilled in the art to variously employ the present disclosure with substantially any suitable detailed structure.

[0027] This description may use the phrases "in one embodiment," "in another embodiment," "in a further embodiment," or "in other embodiments," each of which may refer to one or more of the same or different embodiments according to the present disclosure.

[0028] A first aspect of the present disclosure provides a method for controlling a vehicle air conditioner, comprising:

[0029] S100: Determine a driving mode of the vehicle, where the driving mode includes at least one of an economic mode, a non-economic mode, and a long-range mode;

[0030] In step S100, the vehicle's driving mode should include at least one of an economic mode, a non-economic mode, and a long-range mode. The economic mode, non-economic mode, and long-range mode can be controlled by the user via buttons or a touch screen, and each corresponds to a different vehicle driving mode. Here, different driving modes correspond to different fuel economy or power economy. In this embodiment, under normal use, only one of these three modes can be activated, and two or more modes cannot be activated simultaneously. Generally speaking, the long-range mode is used to simultaneously meet the range requirements of electric vehicle users, the economic mode is primarily used to balance the user's comfort and power saving needs, and the non-economic mode is primarily used to meet the user's comfort needs.

[0031] S200: When the vehicle is in the economy mode or the non-economy mode, determining a heat load requirement level based on whether an air conditioning automatic circulation mode is on, or when the vehicle is in the long-range mode, determining a heat load requirement level;

[0032] In step S200, the vehicle's air conditioner has an automatic air conditioning cycle mode. When this mode is enabled, the air conditioner's internal and external circulation dampers automatically adjust between internal and external circulation based on information such as the outside temperature, interior humidity, and interior temperature. When the vehicle is in either economy or non-economy mode, the heat load demand level is determined by the automatic air conditioning cycle mode. In long-range mode, the heat load demand level is determined directly.

[0033] When the vehicle is in the long cruising mode, determining a thermal load requirement level specifically includes: when the vehicle is in the long cruising mode, the thermal load requirement level is a first level.

[0034] When the vehicle is in the economic mode or the non-economic mode, the heat load demand level is determined based on the on state of the air conditioning automatic circulation mode, specifically including: when the vehicle is in the economic mode and the air conditioning automatic circulation mode is on, the heat load demand level is the second level; when the vehicle is in the economic mode and the air conditioning automatic circulation mode is off, the heat load demand level is the third level; when the vehicle is in the non-economic mode and the air conditioning automatic circulation mode is on, the heat load level is the fourth level.

[0035] S300: Control and adjust the working mode of the air conditioner and / or the operation of predetermined components in the air conditioner based on the heat load demand level.

[0036] When the heat load demand level is the first level, the controlling and adjusting of the operating mode of the air conditioner and / or the operation of predetermined components of the air conditioner based on the heat load demand level in step S300 includes:

[0037] S311, determining whether a battery cooling request or a battery heating request is received;

[0038] In step S311, a corresponding system for battery temperature control can be used to detect the battery temperature to determine whether the battery temperature reaches a cooling threshold or a heating threshold, and then issue a battery cooling request or a battery heating request, so that the system corresponding to the vehicle air conditioning control method in the present disclosure receives the battery cooling request or the battery heating request.

[0039] S312. When a battery cooling request or a battery heating request is received, the air conditioner is controlled to enter a battery cooling mode or a battery heating mode and the blower is kept on; when no battery cooling request or a battery heating request is received, the compressor and the PTC heating device are controlled to be turned off and the blower is kept on.

[0040] In step S312, the air conditioner is controlled to enter the battery cooling mode or the battery heating mode accordingly to ensure that the vehicle's battery can maintain a normal endurance temperature and ensure the realization of the long endurance function.

[0041] In addition, when the heat load demand level is the first level, since the compressor and PTC heating device are either in the off state at the same time, or only maintain low-power operation in response to the battery cooling mode or the battery heating mode, whether the air conditioning automatic circulation mode is turned on or off has little effect on energy saving. Users can choose the circulation direction according to their needs, or turn on the air conditioning automatic circulation mode.

[0042] When the heat load demand level is the second level, the controlling and adjusting of the operating mode of the air conditioner and / or the operation of predetermined components of the air conditioner based on the heat load demand level in step S300 includes:

[0043] S321, controlling and reducing the speed of the compressor and / or the power of the PTC (Positive Temperature Coefficient, i.e., positive temperature coefficient thermistor) heating device;

[0044] In step S321, energy saving and power saving can be achieved to a certain extent by reducing the speed of the compressor and / or the power of the PTC heating device. Specifically, this can be achieved by lowering the preset temperature target. For example, if the user sets the preset temperature target to 24°C (cooling), the preset temperature target can be lowered to 26°C (cooling). For example, if the user sets the preset temperature target to 28°C (heating), the preset temperature target can be lowered to 27°C. The specific reduction value can be adjusted according to actual conditions.

[0045] S322, obtaining the relative humidity of the air in the vehicle;

[0046] In step S322 , the relative humidity of the air in the vehicle may be acquired through corresponding sensors.

[0047] S323: Control and adjust the internal and external circulation dampers based on the relative humidity of the air.

[0048] In step S323, a specific humidity threshold may be set as a preset threshold, and the specific control steps include:

[0049] When the relative humidity of the air is less than a preset threshold, the internal and external circulation damper is controlled to move toward the internal circulation direction;

[0050] When the relative humidity of the air is greater than or equal to a preset threshold, the internal and external circulation damper is controlled to move toward the external circulation direction.

[0051] For example, if the preset threshold is 70%, when the relative humidity is less than 70%, the glass is considered clear and the internal and external circulation dampers are controlled to circulate inward. The air temperature inside the vehicle is generally closer to the preset temperature target, thus saving energy when circulating inward. When the relative humidity is greater than or equal to 70%, the glass is considered to be foggy or has already fogged, and the internal and external circulation dampers are controlled to circulate outward, introducing outside air to ensure clear glass and no fogging, ensuring driving safety. In addition, to prevent frequent rotation of the internal and external circulation dampers, a reset interval can be set as needed.

[0052] When the heat load demand level is the third level, the controlling and adjusting of the operating mode of the air conditioner and / or the operation of predetermined components of the air conditioner based on the heat load demand level in step S300 includes:

[0053] S331 . Control to reduce the speed of the compressor and / or the power of the PTC heating device.

[0054] At the third level, only the economic mode is turned on, and the long-endurance mode and the air-conditioning automatic circulation mode are both in the off state. The speed of the compressor and / or the power of the PTC heating device are reduced by lowering the preset temperature target, for example, as exemplified in step S321. That is, at this heat load demand level, an economic mode that simply limits the power consumption of the air conditioner is achieved.

[0055] When the heat load demand level is the fourth level, the controlling and adjusting of the operating mode of the air conditioner and / or the operation of predetermined components of the air conditioner based on the heat load demand level in step S300 includes:

[0056] S341. Obtaining relative humidity of air in the vehicle;

[0057] In step S341 , the relative humidity of the air in the vehicle may be acquired through corresponding sensors.

[0058] S342. Control and adjust the movement direction of the internal and external circulation dampers based on the relative humidity of the air.

[0059] In step S342 , the speed of the compressor and / or the power of the PTC heating device are reduced by, for example, reducing the preset temperature target as exemplarily described in step S321 .

[0060] In the fourth level, since the long-endurance mode and economic mode are both turned off and the non-economic mode is turned on, it is believed that the user at this time has a lower demand for energy saving and a higher requirement for the comfort of the vehicle environment. At this time, the air conditioning automatic circulation mode adjusts the internal and external circulation directions according to the relative humidity of the air. In the case of low humidity, the air is kept in internal circulation first to save a certain amount of electricity. In the case of high humidity, the external circulation is prioritized to ensure the removal of fog on the glass and ensure driving safety.

[0061] More specifically, when the vehicle is in the non-economic mode and the air-conditioning automatic circulation mode is off, the heat load level is level five (i.e., at level five, all energy-saving control modes on the air-conditioning and vehicle are turned off). At this time, the control of the air-conditioning system is completely handed over to the user, who can control the air-conditioning according to his or her own needs to obtain a better comfort experience.

[0062] Preferably, before determining the driving mode of the vehicle in step S100, the following steps are included:

[0063] Determine whether the air conditioner is in defrost mode, and proceed to subsequent steps only when the defrost mode is off. In this way, the operation of the defrost mode can be prioritized to ensure driving safety.

[0064] It should be noted that some control strategies involved in the long-endurance mode can be carried out simultaneously with the defrost mode, such as the control of battery discharge. Therefore, when the long-endurance mode and the defrost mode are turned on at the same time, the control strategies that need to be kept on and those that need to be turned off should be determined according to demand.

[0065] The vehicle air-conditioning control method disclosed in the present invention is divided into different heat load demand levels according to different degrees of heat load demand through the on / off states of the economic mode, non-economic mode and long-endurance mode included in the vehicle's driving mode. Different control strategies are adopted to control and adjust the working mode of the air-conditioning and / or the operation of predetermined components of the air-conditioning (such as a compressor, a PTC heating device, a blower, etc.) according to different heat load demand levels, thereby achieving different degrees of energy-saving and comfort requirements corresponding to different heat load demand levels. Users can adjust the on / off of the economic mode, non-economic mode and long-endurance mode according to actual conditions. The identification of users' energy-saving and comfort requirements is more detailed, and users' requirements for endurance and comfort, etc., are better met.
