PROBLEM TO BE SOLVED: To provide a vehicle heat management system suppressed in occurrence of wasteful heat consumption.SOLUTION: A heat management system 19 includes: a water heater 22 with which heating of coolant and stop of the heating can be attained; an oil cooler 32 which exchanges heat between lubricant lubricating a transaxle 3, and the coolant; a coolant circulation device 23 which switches the circulation condition of the coolant between a first circulation condition where the coolant circulates between the water heater 22 and the oil cooler 32, and a second circulation condition where the coolant circulates between the water heater 22 and a heater core 24; and a control unit 45 making the coolant circulation device 23 switch the circulation condition so that warm up of the transaxle 3 is prior to the vehicle chamber heating, when the warmup requirement before drive and heating requirement before drive are overlapped.SELECTED DRAWING: Figure 2 |
