PROBLEM TO BE SOLVED: To provide a temperature control device for a vehicle for improving energy efficiency of the whole of the vehicle by efficiently heating a cabin of the vehicle and performing temperature controls for a transmission and an internal combustion engine. SOLUTION: A first heat storage tank 44A is provided in a coolant flow passage 34 in which coolant circulating on the inside and outside of the internal combustion engine 12 flows. A second heat storage tank 44B is provided in an ATF flow passage 38 in which ATF circulating on the inside and outside of the automatic transmission 18 flows. The coolant flow passage 34 and the ATF flow passage 38 are connected by a heat exchanger 40 so that coolant and ATF may be heat-exchangeable. The coolant flow passage 34 and the ATF flow passage 38 are also connected to a heater core 58 to be a heating source for cabin heating. When at least one of the internal combustion engine 12, the automatic transmission 18 and warming-up of the heater core 58 is required, a control part 56 switches the first and second heat storage tanks 44A and 44B, the coolant flow passages 34 and the ATF flow passage 38 and supplies heat that the first and second heat storage tanks 44A and 44B have to a heating requiring part. |
