Abstract
When a request of a warming-up of a transmission is generated, a hybrid ECU sets a target input rotational speed of the transmission where a heat loss quantity of a MG becomes maximum, based on a request driving force of a vehicle. In this case, the heat loss quantity is a quantity of a heat loss causing an increasing of a temperature of an ATF in the MG. Thus, the hybrid ECU sets the target input rotational speed where the heat loss quantity becomes maximum and controls the transmission and the MG to output power that meets the request driving force of the vehicle. Since the hybrid ECU controls a torque of the MG, a torque of the engine, and a transmission ratio of the transmission to achieve the target input rotational speed, the hybrid ECU controls the MG, the engine, and the transmission in a condition that the heat loss quantity becomes maximum.
