The invention provides a temperature control system for a vehicle, which cools a rotating electric machine when it is necessary to cool the rotating electric machine, and can improve fuel economy of the vehicle when it is not necessary to cool the rotating electric machine. A vehicle temperature control system is provided with: a first temperature control circuit (61) through which a first temperature control medium circulates and which controls the temperature of an electric motor and a transmission; a second temperature control circuit (62) through which a second temperature control medium circulates; a heat exchanger (63) that exchanges heat between the first temperature control medium and the second temperature control medium; a valve device (626) that adjusts the flow rate of the second temperature control medium flowing through the heat exchanger; and a control unit (ECU) having a valve opening and closing control unit for controlling the valve opening and closing of the valve unit. The valve opening/closing control unit controls the valve device to close when the temperature of the first temperature control medium is less than a predetermined temperature, and controls the valve device to open when the temperature of the first temperature control medium is equal to or greater than the predetermined temperature.
本发明提供一种车辆用调温系统,其在需要冷却旋转电机的情况下冷却旋转电机,并且在不需要冷却旋转电机的情况下能够提高车辆的燃料经济性。车辆用调温系统具备:第一调温回路(61),其供第一调温介质循环而对电动机和变速装置进行调温;第二调温回路(62),其供第二调温介质循环;热交换器(63),其在第一调温介质与第二调温介质之间进行热交换;阀装置(626),其调整在热交换器中流动的第二调温介质的流量;以及控制装置(ECU),其具有控制阀装置的开阀和闭阀的阀开闭控制部。阀开闭控制部在第一调温介质的温度小于规定温度的情况下将阀装置控制为闭阀,当第一调温介质的温度成为规定温度以上时,将阀装置控制为开阀。
