Benefits of technology

[0010]In addition, other aspects of the present invention have been directed to provide a heat exchange system for a vehicle and a control method thereof that can minimize unnecessary cooling loss and improves fuel economy of a vehicle and durability of a driving device.
[0021]The pump may be turned off so as to prevent heat loss of the coolant in a case that a coolant temperature is lower than a first predetermined temperature.
[0023]The pump may be turned off so as to minimize wasting energy of the heat exchange system in a case that the oil temperature is higher than or equal to the second predetermined temperature and is lower than a third predetermined temperature.
[0024]The pump may be turned on so as to prevent overheating of the automatic transmission and the differential apparatus in a case that the oil temperature is higher than or equal to a third predetermined temperature.

Problems solved by technology

Therefore, it is not easy to warm up oil in the differential apparatus and optimal fuel economy may not be gained.
