[0034] It should be understood that the specific embodiments described herein are merely intended to explain the present application and not to limit the present application.

[0035] In a first aspect, the embodiment of the present application provides a vehicle air conditioner fan control method.

[0036] In order to more clearly show the vehicle air conditioner fan control method provided by the embodiments of the present application, first introduce the application scenario of the vehicle air conditioner fan control method provided by the embodiments of the present application.

[0037] The vehicle air conditioner fan control method provided by the embodiments of the present application is applied when the vehicle opens the air conditioner and performs refrigeration. In order to quickly refrigerate, the controller issues an instruction to control the fan to start, the fan is immediately fully engaged, the fan performs heat dissipation on the condenser of the air conditioner, thereby accelerating the heat dissipation process of the condenser and improving the refrigeration effect of the air conditioner. However, when the fan is fully engaged, the rotation speed of the fan will instantaneously increase, thereby causing the noise in the vehicle to instantaneously increase, especially when the noise in the vehicle is relatively low, which will bring poor user experience. Therefore, it is necessary to solve this problem of poor user experience.

[0038] In an embodiment, referring to Figure 1 , Figure 1 The flowchart of the vehicle air conditioner fan control method embodiment of the present application is shown in the figure. Figure 1 The vehicle air conditioner fan control method comprises the following steps.

[0039] In step S10, when it is detected that the vehicle air conditioner refrigeration mode is opened, the current vehicle speed is acquired.

[0040] In the embodiment, mainly aiming at the case of the vehicle air conditioner refrigeration mode, the heating mode currently mainly uses a separate heating system, which usually utilizes a large amount of heat brought by the cooling liquid during the engine operation, and then performs heating through heat exchange. When it is detected that the vehicle air conditioner refrigeration mode is opened, it represents that the user has a refrigeration demand at this time. The current vehicle speed of the vehicle is acquired from the electronic control system of the vehicle and the like, which is used for subsequent control and judgment of the fan.

[0041] Step S20, if the current vehicle speed is less than the preset vehicle speed, the air conditioning fan is controlled to gradually increase from the initial speed, through one or more intermediate speeds, to the target speed within the preset time length.

[0042] In this embodiment, the size of the preset vehicle speed can be set according to whether the natural wind generated when the vehicle is running at a certain speed can meet the heat dissipation demand of air conditioning refrigeration. If the current vehicle speed is less than the preset vehicle speed, it means that the vehicle is currently running at low speed or the engine is in idle condition. The engine idle condition usually refers to the state that the vehicle is ignited but waiting. At this time, the natural wind of the vehicle cannot meet the heat dissipation demand of air conditioning refrigeration, and the air conditioning fan must be turned on for heat dissipation to achieve the purpose of rapid refrigeration. By controlling the air conditioning fan to gradually increase from the initial speed, through one or more intermediate speeds, to the target speed within the preset time length, for example, the preset time length is 60 seconds, the initial speed is 200 revolutions per minute, the target speed is 1000 revolutions per minute, and the intermediate speed can be 500 revolutions per minute. The time corresponding to the intermediate speed can be 30 seconds, that is, the speed of the fan is controlled to increase from the initial speed of 200 revolutions per minute to 500 revolutions per minute at 30 seconds, and then to 1000 revolutions per minute at 60 seconds. Thus, the situation that the speed of the fan instantaneously increases to the target speed after the air conditioning is turned on for refrigeration and generates a large noise can be avoided, the purpose of reducing the noise in the vehicle is achieved, the user driving experience is improved, and the energy consumption of the fan is reduced.

[0043] In this embodiment, for the case of vehicle air conditioning refrigeration mode, when it is detected that the vehicle air conditioning refrigeration mode is turned on, it means that the user has a refrigeration demand at this time. The air conditioning fan is controlled according to the current vehicle speed. If the current vehicle speed is less than the preset vehicle speed, it means that the vehicle is currently running at low speed or the engine is in idle condition. At this time, the natural wind of the vehicle cannot meet the heat dissipation demand of air conditioning refrigeration, and the air conditioning fan must be turned on for heat dissipation to achieve the purpose of rapid refrigeration. By controlling the air conditioning fan to gradually increase from the initial speed, through one or more intermediate speeds, to the target speed within the preset time length, the situation that the speed of the fan instantaneously increases to the target speed after the air conditioning is turned on for refrigeration and generates a large noise can be avoided, the purpose of reducing the noise in the vehicle is achieved, the user driving experience is improved, and the energy consumption of the fan is reduced.

[0044] Further, in an embodiment, with reference to Figure 2 , Figure 2 The control and setting flowchart of the vehicle air conditioning fan control method of the embodiment of the present application is shown in FIG. 1. Figure 2 As shown in FIG. 1, after step S20, it includes:

[0045] Step S30, if the current vehicle speed is greater than or equal to the preset vehicle speed, the fan of the air conditioning is set to follow the speed.

[0046] In the embodiment, if the current vehicle speed is greater than or equal to the preset vehicle speed, the vehicle is in a state of driving at a high speed, at this time, the natural windward of the vehicle can meet the heat dissipation demand of air conditioning refrigeration, and it is not necessary to use the air conditioning fan to dissipate heat for refrigeration, therefore, the fan of the air conditioner can be set to follow the speed, so as to reduce the energy consumption of the fan, and also reduce the noise caused by the speed of the fan. The follow-up speed means that the fan is not actively controlled, and the fan is not given a control driving force, and the fan clutch is in a disconnected state, and the fan has a naturally generated speed.

[0047] Further, in an embodiment, referring to Figure 3 , Figure 3 for Figure 1 the detailed flowchart of step S20 in the embodiment, as shown in Figure 3 , step S20 includes:

[0048] Step S201, if the current vehicle speed is less than the preset vehicle speed, the ambient temperature and the pressure value of the air conditioning pipeline are obtained;

[0049] Step S202, if the ambient temperature is less than or equal to the preset ambient temperature, when the pressure value of the air conditioning pipeline is greater than the preset pressure value, the air conditioning fan is controlled to gradually increase from the initial speed to the target speed through one or more intermediate speeds within the preset time length.

[0050] Step S203, if the ambient temperature is greater than the preset ambient temperature, the air conditioning fan is controlled to gradually increase from the initial speed to the target speed through one or more intermediate speeds within the preset time length.

[0051] In the embodiment, when the current vehicle speed is less than the preset vehicle speed, that is, the vehicle is in a state of driving at a low speed or the engine is in an idle working condition, the air conditioning fan is controlled according to the ambient temperature and the pressure value of the air conditioning pipeline. The pressure value of the air conditioning pipeline is obtained by using a pressure sensor, so as to avoid that the current pressure switch usually uses a two-state or three-state switch, which cannot collect the pressure signal of the air conditioning pipeline in real time, and thus the speed of the fan cannot be controlled in real time. When the real-time ambient temperature is less than or equal to the preset ambient temperature, for example, the preset ambient temperature is set to 25℃, it represents that the user's demand for rapid refrigeration is not too strong at this time, therefore, when the pressure value of the air conditioning pipeline is greater than the preset pressure value, the control of the air conditioning fan is performed again, the fan is started after a delay, and the purpose of saving the energy consumption of the fan is achieved. When the real-time ambient temperature is greater than the preset ambient temperature, for example, 25℃, since the ambient temperature is high, it represents that the user's demand for rapid refrigeration is very strong at this time, therefore, the pressure value of the air conditioning pipeline is not considered, and the fan of the air conditioner is controlled immediately when the air conditioning refrigeration is started, and the purpose of immediately meeting the user's demand for refrigeration is achieved.

[0052] Further, in an embodiment, the preset pressure value includes a first preset pressure value, a second preset pressure value and a third preset pressure value, the first preset pressure value is greater than the second preset pressure value, and the second preset pressure value is greater than the third preset pressure value, and the control of the air conditioning fan to gradually increase from the initial rotating speed to the target rotating speed through one or more intermediate rotating speeds within the preset time period when the pressure value of the air conditioning pipeline is greater than the preset pressure value includes:

[0053] If the vehicle is uphill driving, the air conditioning fan is controlled to gradually increase from the initial rotating speed to the target rotating speed through one or more intermediate rotating speeds within the preset time period when the pressure value of the air conditioning pipeline is greater than the first preset pressure value.

[0054] If the vehicle is downhill driving, the air conditioning fan is controlled to gradually increase from the initial rotating speed to the target rotating speed through one or more intermediate rotating speeds within the preset time period when the pressure value of the air conditioning pipeline is greater than the second preset pressure value.

[0055] If the vehicle is flat road driving or the vehicle speed is zero, the air conditioning fan is controlled to gradually increase from the initial rotating speed to the target rotating speed through one or more intermediate rotating speeds within the preset time period when the pressure value of the air conditioning pipeline is greater than the third preset pressure value.

[0056] In the embodiment, when the vehicle is uphill driving, the rotating speed of the fan will increase with the increase of the cooling liquid temperature, so the request of the air conditioning opening to the rotating speed of the fan can be delayed more greatly, and therefore the first preset pressure value is set to be the maximum. When the vehicle is downhill driving, the air conditioning is naturally cooled, so the request of the air conditioning opening to the rotating speed of the fan can be delayed less greatly, and therefore the second preset pressure value is set to be less than the first preset pressure value. When the vehicle is flat road driving or the vehicle speed is zero, there is neither the influence of the increase of the cooling liquid temperature on the rotating speed of the fan nor the natural cooling of the air conditioning, and therefore the third preset pressure value is set to be the minimum. In combination with different vehicle conditions, the energy consumption of the fan can be more reasonably reduced.

[0057] Further, in an embodiment, the control of the air conditioning fan to gradually increase from the initial rotating speed to the target rotating speed through one or more intermediate rotating speeds within the preset time period includes:

[0058] The interpolation method is used to control the air conditioning fan to gradually increase from the initial rotating speed to the target rotating speed through one or more intermediate rotating speeds within the preset time period.

[0059] In the embodiment, interpolation is an important method of discrete function approximation, and by using the method, the approximate value of a function at other points can be estimated by the value condition of the function at a limited number of points. For example, the preset time length is 60 seconds, the initial rotating speed is 200 revolutions per minute, and the target rotating speed is 1000 revolutions per minute. The intermediate rotating speed of 500 revolutions per minute corresponding to the intermediate time of 30 seconds can be determined by the interpolation method, and a plurality of intermediate rotating speeds, such as the intermediate rotating speed of 250 revolutions per minute corresponding to the intermediate time of 15 seconds, can also be determined. By gradually increasing the one or more intermediate rotating speeds to the target rotating speed, the situation that the rotating speed of the fan is instantaneously increased to the target rotating speed after the air conditioner is turned on to generate refrigeration, thereby generating a large noise, can be avoided, the purpose of reducing the noise in the vehicle is achieved, the user driving experience can be improved, and the energy consumption of the fan can be reduced.

[0060] Further, in an embodiment, the preset time length is set according to refrigeration demand, and the target rotating speed is set according to energy consumption demand.

[0061] In the embodiment, the preset time length is, for example, 60 seconds. If the user does not feel the refrigeration effect of the air conditioner after the preset time length, such as 60 seconds, the user will subjectively recognize that the refrigeration effect of the air conditioner is poor. Therefore, the preset time length can be set according to the refrigeration demand of the user. For example, if the refrigeration demand is strong, the preset time length can be shortened. For another example, the preset time length can be set in combination with the ambient temperature. For example, if the ambient temperature is low, the preset time length can be prolonged. The target rotating speed is, for example, 1000 revolutions per minute. By setting a lower target rotating speed, the purpose of saving the energy consumption of the fan can be achieved.

[0062] In a second aspect, the embodiment of the present application further provides a vehicle air conditioner fan control device.
