发明名称 Method for controlling a cooling circuit for an internal-combustion engine
摘要 A method for controlling a cooling circuit of an internal combustion engine which includes a coolant pump for adjusting a coolant flow rate, a radiator in which heat is exchanged between the coolant and an air flow which can be controlled by a fan, and a control unit which controls at least the speed of the coolant pump and of the fan as a function of a required temperature value of the coolant. In order to minimize the power consumption of the pump and of the fan while maintaining an optimum coolant temperature, the speed of the coolant pump and the speed of the fan are controlled based on a comparison of the time efficiencies of the coolant pump and of the fan for the heat flow transmitted to the radiator.
