Electronic fan control method and system, readable storage medium and automobile

Abstract

The invention discloses an electronic fan control method and device, a readable storage medium and an automobile. When the air conditioner is in a refrigeration mode, the vehicle environment temperature and the air conditioner system pressure are obtained firstly; if the vehicle environment temperature is larger than the first preset environment temperature threshold value and smaller than the second preset environment temperature threshold value, whether the pressure of the air conditioning system is smaller than a first preset pressure threshold value or not is further judged; if the pressure of the air conditioning system is smaller than a first preset pressure threshold value and the current vehicle speed is larger than a first vehicle speed threshold value, the electronic fan is turned off, and unnecessary energy consumption of the electronic fan is reduced; and if the pressure of the air conditioning system is smaller than the first preset pressure threshold value and the current vehicle speed is smaller than the second vehicle speed threshold value, the electronic fan is controlled to start a low-speed gear mode, and too high energy consumption is avoided. Actual measurement shows that when the automobile air conditioner is started, oil consumption increase caused by the electronic fan can be effectively reduced.

Description

technical field [0001] The present invention relates to the technical field of automobile air conditioning control, in particular to an electronic fan control method, system, readable storage medium and automobile. Background technique [0002] As the problem of climate warming becomes increasingly prominent and global oil prices continue to rise, when users turn on the air conditioner in summer, the cost of using the car continues to rise. Therefore, the complaint that the air conditioner is turned on leads to increased fuel consumption has become extremely prominent. In the automotive air-conditioning system, the electronic fan is the "right-hand man" for the heat dissipation of the air-conditioning system, and it is a large energy consumer of the air-conditioning system. [0003] The current mainstream electronic fan control logic is simple. The following is the control logic of the electronic fan of an SUV model: [0004] Set the medium pressure value of the air conditi...
