Document Type and Number:
WIPO Patent Application WO/2024/046214
Kind Code:
A1
Abstract:
The present invention provides a cooperative control method and apparatus for active grille shutters and a cooling fan. The method comprises: when a vehicle air conditioning system is started, acquiring the vehicle speed and the pressure of the vehicle air conditioning system in real time, and determining a preset speed interval in which the current vehicle speed is located; and according to the preset speed interval in which the current vehicle speed is located and a change in the pressure of the vehicle air conditioning system, cooperatively controlling the degree of opening of the active grille shutters and the degree of opening of the cooling fan. In the present invention, by means of dividing up different vehicle speed intervals, and according to influence weights of the degree of opening of the active grille shutters and the cooling fan duty cycle in the vehicle speed intervals, the degree of opening of the active grille shutters and the cooling fan duty ratio are cooperatively controlled, and the degree of opening of the active grille shutters and the cooling fan duty cycle are dynamically adjusted, thereby achieving maximum reduction of air conditioning energy consumption.
