Abstract
A control apparatus controls the temperature of hydraulic fluid in a power-transmission system that has a hydrodynamic power-transmission system designed to transmit power between one rotational member and the another rotational member and that has a transmission coupled to the another rotational member in such a manner that power can be transmitted. The temperature of the hydraulic fluid can be controlled by controlling a subsystem associated with the power-transmission system while a vehicle is coasting.
