Cooling system for vehicle

Abstract

A vehicle cooling system includes: a channel allowing a liquid medium cooling a drive device of the vehicle to circulate; a flow rate detection unit detecting a flow rate of the liquid medium flowing in the channel; a temperature sensor detecting a temperature of the liquid medium; a pump provided on the channel for circulating the liquid medium; a rotational speed sensor detecting a rotational speed of the pump; and a control device controlling drive of the pump. The control device identifies a malfunctioning part of the cooling system based on the flow rate and the temperature of the liquid medium and the rotational speed of the pump. Thus, since abnormalities of the cooling mechanism can be detected with higher precision so that the abnormalities are distinguished from each other, it is a limited part that should be checked when repairs are made and the work efficiency is improved.
