Abstract (en)

A cooling system includes a cooling circuit (R2), a pump (13; 32), an electric fan (11; 31), an electric motor (12) connected with the electric fan (11; 31), and a controller (20) for controlling the electric motor (12). The pump (13; 32) is capable of being driven by the electric fan (11; 31) that receives a ram airflow generated when the motor vehicle is running. The controller (20) controls the electric motor (12) to be shifted between in a first operation state where electric power is supplied to the motor (12) and in a second operation state where no electric power is supplied to the motor (12). The pump (13; 32) is driven by a rotating torque of the ram airflow and a rotating torque of the motor (12) in the first operation state, and the pump (13; 32) is driven by the rotating torque generated by the ram airflow without the rotating torque of the motor (12) in the second operation state.
