Abstract:
A control apparatus for a vehicle cooling apparatus that includes: a PCU cooling unit for cooling a power control unit controlling an electric motor; a T/A cooling unit for cooling a drive-force transmitting apparatus including the electric motor; and a heat exchanger for transferring heat between the PCU cooling unit and the T/A cooling unit. The T/A cooling unit includes a first pump for circulating a refrigerant of the T/A cooling unit, while the PCU cooling unit includes a second pump for circulating a refrigerant of the PCU cooling unit. The control apparatus includes a controlling portion configured to cause the first pump to be driven when a temperature of the power control unit is higher than a threshold temperature value and a temperature of the refrigerant of the PCU cooling unit is higher than a temperature of the refrigerant of the T/A cooling unit.
