Therefore, specific structural and functional details of the disclosed embodiments are not intended to limit, but merely as a basis for the claims and a representative basis for teaching one skilled in the art to variously employ the present disclosure in virtually any appropriate detailed structure.

[0026] The specification can use phrases such as "in one embodiment", "in another embodiment", "in yet another embodiment", or "in other embodiments", which can refer to one or more of the same or different embodiments under the present disclosure.

[0027] A first aspect of the present disclosure provides a control method of a vehicle air conditioner, comprising:

[0028] S100, determining a driving mode of a vehicle, the driving mode comprising at least one of an economy mode, a non-economy mode, and a long-range mode;

[0029] In step S100, the driving mode of the vehicle should at least include one of the economy mode, the non-economy mode, and the long-range mode, wherein the economy mode, the non-economy mode, and the long-range mode can be controlled by the user through buttons or touch screens, etc., and correspond to different vehicle driving modes, respectively. Here, different driving modes correspond to different fuel economy or electric energy economy. In the present embodiment, under normal use conditions, only one of the three modes can be activated, and two or more modes cannot be activated simultaneously. Generally, the long-range mode is used to meet the range requirements of electric vehicle users, the economy mode is mainly used to balance the comfort and power saving requirements of users, and the non-economy mode is mainly used to meet the comfort requirements of users.

[0030] S200, determining a heat load demand level based on an open state of an air conditioner automatic circulation mode when the vehicle is in the economy mode or the non-economy mode, or determining the heat load demand level when the vehicle is in the long endurance mode;

[0031] In step S200, the air conditioner on the vehicle has an air conditioner automatic circulation mode, and when the air conditioner automatic circulation mode is open, the inside-outside circulation air door of the air conditioner can be automatically adjusted in two circulation directions, for example, inside circulation and outside circulation, according to information such as outside temperature, indoor humidity, indoor temperature, etc. When the vehicle is in the economy mode or the non-economy mode, the heat load demand level is determined by the open state of the air conditioner automatic circulation mode, and in the long endurance mode, the heat load demand level can be directly determined.

[0032] When the vehicle is in the long endurance mode, the heat load demand level is determined, specifically including: when the vehicle is in the long endurance mode, the heat load demand level is the first level.

[0033] When the vehicle is in the economy mode or the non-economy mode, the heat load demand level is determined based on the open state of the air conditioner automatic circulation mode, specifically including: when the vehicle is in the economy mode and the air conditioner automatic circulation mode is open, the heat load demand level is the second level; when the vehicle is in the economy mode and the air conditioner automatic circulation mode is closed, the heat load demand level is the third level; when the vehicle is in the non-economy mode and the air conditioner automatic circulation mode is open, the heat load level is the fourth level.

[0034] S300, controlling and adjusting the working mode of the air conditioner and / or the operation of the predetermined components in the air conditioner based on the heat load demand level.

[0035] When the heat load demand level is the first level, the control and adjustment of the working mode of the air conditioner and / or the operation of the predetermined components in the air conditioner based on the heat load demand level in step S300 includes:

[0036] S311, determining whether a battery cooling request or a battery heating request is received;

[0037] In step S311, a corresponding system for battery temperature control can be used to detect the temperature of the battery to determine whether the temperature of the battery reaches a cooling threshold or a heating threshold, and then send a battery cooling request or a battery heating request, so that the system corresponding to the control method of the vehicle air conditioner in the present disclosure receives the battery cooling request or the battery heating request.

[0038] S312, when receiving the battery cooling request or the battery heating request, controlling the air conditioner to enter the battery cooling mode or the battery heating mode and keeping the blower in the open state; when not receiving the battery cooling request or the battery heating request, controlling to close the compressor and the PTC heating device and keeping the blower in the open state.

[0039] In step S312, the air conditioner is correspondingly controlled to enter the battery cooling mode or the battery heating mode, so as to ensure that the battery of the vehicle can maintain a normal temperature for cruising and ensure the realization of the long cruising function.

[0040] In addition, when the heat load demand level is the first level, since the compressor and the PTC heating device are either in the closed state at the same time or only keep a low-power operation in response to the battery cooling mode or the battery heating mode, whether the air conditioner automatic circulation mode is started or not has little effect on energy saving, and the user can select the circulation direction or start the air conditioner automatic circulation mode according to needs.

[0041] When the heat load demand level is the second level, the control of adjusting the working mode of the air conditioner and / or the operation of the predetermined components in the air conditioner based on the heat load demand level in step S300 includes:

[0042] S321, controlling to reduce the rotating speed of the compressor and / or the power of the PTC (Positive Temperature Coefficient, i.e. positive temperature coefficient thermistor) heating device;

[0043] In step S321, by reducing the rotating speed of the compressor and / or the power of the PTC heating device, a certain degree of energy saving effect is realized, specifically, the preset temperature target can be reduced, for example, the user sets the preset temperature target to 24°C (cooling), and the preset temperature target can be reduced to 26°C (cooling), and for example, the user sets the preset temperature target to 28°C (heating), and the preset temperature target can be reduced to 27°C, and the specific reduction value can be adjusted according to actual conditions.

[0044] S322, obtaining the air relative humidity in the vehicle;

[0045] In step S322, the air relative humidity in the vehicle can be obtained by a corresponding sensor.

[0046] S323, controlling and adjusting the inside-outside circulation air door based on the air relative humidity.

[0047] In step S323, a specific humidity threshold value can be set as a preset threshold value, and the specific control steps include:

[0048] When the air relative humidity is less than a preset threshold, controlling the inside-outside circulating air door to move in an inside circulating direction;

[0049] When the air relative humidity is greater than or equal to the preset threshold, controlling the inside-outside circulating air door to move in an outside circulating direction.

[0050] For example, the preset threshold is 70%, when the air relative humidity is less than 70%, it is considered that the glass is not fogged, and the inside-outside circulating air door is controlled to rotate in the inside circulating direction. The temperature of the air in the vehicle is generally close to the preset temperature target, so the electric energy can be saved in the inside circulating condition. When the air relative humidity is greater than or equal to 70%, it is considered that the glass may be fogged or has been fogged, and the inside-outside circulating air door is controlled to rotate in the outside circulating direction, and the outside air is introduced to ensure that the glass is clear and not fogged, and the driving safety is ensured. In addition, in order to prevent the inside-outside circulating air door from rotating frequently, a certain reset interval can be set according to the needs.

[0051] When the thermal load demand level is the third level, the step S300 of controlling and adjusting the working mode of the air conditioner and / or the operation of the predetermined components in the air conditioner based on the thermal load demand level comprises:

[0052] S331, controlling to reduce the rotating speed of the compressor and / or the power of the PTC heating device.

[0053] Under the third level, only the economy mode is turned on, and the long endurance mode and the air conditioner automatic circulation mode are in the off state. The rotating speed of the compressor and / or the power of the PTC heating device is reduced by the way of reducing the preset temperature target as exemplarily described in the step S321, that is, the economy mode of simply limiting the power consumption of the air conditioner is realized under the thermal load demand level.

[0054] When the thermal load demand level is the fourth level, the step S300 of controlling and adjusting the working mode of the air conditioner and / or the operation of the predetermined components in the air conditioner based on the thermal load demand level comprises:

[0055] S341, obtaining the air relative humidity in the vehicle;

[0056] In the step S341, the air relative humidity in the vehicle can be obtained by a corresponding sensor.

[0057] S342, controlling and adjusting the moving direction of the inside-outside circulating air door based on the air relative humidity.

[0058] In the step S342, the rotating speed of the compressor and / or the power of the PTC heating device is reduced by the way of reducing the preset temperature target as exemplarily described in the step S321.

[0059] In the fourth level, since the long endurance mode and the economic mode are closed and the non-economic mode is opened, it is considered that the user at this time has a lower demand for energy saving and a higher demand for comfort of the in-vehicle environment. At this time, the air conditioner automatic circulation mode adjusts the inside-outside circulation direction according to the relative humidity of the air. In the case of lower humidity, the air is kept inside circulation in priority, saving a certain amount of electric energy. In the case of higher humidity, outside circulation is given priority to ensure the removal of fog on the glass and ensure driving safety.

[0060] More specifically, when the vehicle is in the non-economic mode and the air conditioner automatic circulation mode is closed, the heat load level is the fifth level (i.e., in the fifth level, the air conditioner and the mode related to energy saving control on the vehicle are all closed), at this time, the control right of the air conditioning system is completely handed over to the user, and the user can control the air conditioner according to his own needs to get a better comfort experience.

[0061] Preferably, before the determination of the driving mode of the vehicle in step S100, it comprises:

[0062] It is judged whether the air conditioner is in the defrosting mode. Only when the defrosting mode is closed, the subsequent steps are performed. In this way, the operation of the defrosting mode can be ensured in priority to ensure driving safety.

[0063] It should be noted that part of the control strategy involved in the long endurance mode can be performed simultaneously with the defrosting mode, such as the control of battery discharge. Therefore, when the long endurance mode and the defrosting mode are opened at the same time, the control strategies that need to be kept open and closed should be determined according to the needs.

[0064] The control method of the vehicle air conditioner of the present disclosure divides the heat load demand into different heat load demand levels according to the on-off state of the economic mode, the non-economic mode and the long endurance mode included in the driving mode of the vehicle, and adopts different control strategies to control the working mode of the air conditioner and / or the operation of the predetermined components (such as the compressor, the PTC heating device, the air blower, etc.) of the air conditioner according to different heat load demand levels, so as to realize different degrees of energy saving demand and comfort demand corresponding to different heat load demand levels.
