FIELD: cooling.
SUBSTANCE: invention relates to engine cooling system. Disclosed are methods for evaluating cooling requirement of vehicle power transmission component and selecting operating mode of vehicle cooling system based on evaluation of requirements for cooling of power transmission component of vehicle and energy consumption by components of cooling system. Based on the selected operating mode, it is possible to simultaneously control the radiator fan speed, the coolant system pump output, opening degree of louvre of vehicle radiator grate and opening degree of ventilation holes connected to insulating casing of power transmission component, which allows to minimize parasitic losses during cooling with simultaneous satisfaction of requirements for vehicle cooling.
EFFECT: invention provides improvement of engine cooling, reduction of parasitic losses and fuel efficiency.
