Abstract
A maximum charging power when a battery is warmed up is set, and a target rotation speed is set based on the sum of the engine output required to drive the vehicle and the maximum charging power. The target charging power when the battery is warmed up, is computed based on the charge state of the battery. The target torque of the engine is set by dividing the target engine output, obtained based on the sum of the engine output required to drive the vehicle and the target charging power, by the engine rotation speed. In the battery warm-up control, the rotation speed of the engine and generator is controlled to the target rotation speed, and the torque of the engine is controlled to the target torque.
