PROBLEM TO BE SOLVED: To realize inhibition of the occurrence of engine stall and improvement of fuel consumption at extremely-low temperature.SOLUTION: A vehicle includes: an internal combustion engine E; a radiator 91 to which an engine coolant for cooling the internal combustion engine E is led, the radiator 91 used for cooling the engine coolant; a radiator passage 93 which leads the engine coolant to the radiator 91 and flows the engine coolant back to the internal combustion engine E; a first on-off valve 96 which opens and closes the radiator passage 93; an oil warmer 80a for a transmission which is used for heating an oil to be supplied to an automatic transmission 8 through heat exchange with the engine coolant; a coolant circulation pipeline 95 which leads the engine coolant to the oil warmer 80a for the transmission and flows the engine coolant back to the internal combustion engine; and a second on-off valve 97 which opens and closes the coolant circulation pipeline 95. The vehicle further includes a control device which performs controlling for opening the second on-off valve 97 when a temperature of the engine coolant is lower than a first predetermined temperature or the temperature of the engine coolant exceeds a second predetermined temperature at the higher temperature side than the first predetermined temperature. |
