The invention discloses an electric vehicle air conditioner compressor control method based on three CAN buses. A first CAN bus, a second CAN bus and a third CAN bus are arranged in an electric vehicle; the electric vehicle further comprises a vehicle control unit, an air conditioner controller, an air conditioner compressor controller, a first signal conversion module and a second signal conversion module; the air conditioner controller sends air conditioner compressor starting request information to the vehicle control unit through the first signal conversion module; the air conditioner controller sends air conditioner compressor starting request information to the vehicle control unit through the second signal conversion module; and the vehicle controller carries out joint verificationon the received air conditioner compressor starting request information; and if the joint verification is passed, the air conditioner compressor controller is controlled to start an air conditioner compressor.
本发明公开了一种基于三路CAN总线的电动汽车空调压缩机控制方法,电动汽车内设置有第一CAN总线、第二CAN总线、和第三CAN总线,还包括整车控制器、空调控制器、和压缩机控制器,以及第一信号转换模块和第二信号转换模块;所述空调控制器经由所述第一信号转换模块向所述整车控制器发出空调压缩机启动请求信息,以及,所述空调控制器经由所述第二信号转换模块向所述整车控制器发出空调压缩机启动请求信息;所述整车控制器对接收到的上述空调压缩机启动请求信息进行联合校验,若通过联合校验,则控制所述压缩机控制器启动空调压缩机。
