Abstract
A target output torque and target power generation output of a motor are computed based on a vehicle running state, and a target input rotation speed of a generator is computed based on the target power generation output. The final target output torque of the motor is computed by performing delay processing on the target output torque using a filter of second or higher order. The same delay processing by an identical filter is performed on the target input rotation speed, and the final target input rotation speed supplied to the generator is computed. In this way, the response of the driving power output (=power consumption of the motor) and the generated power of the generator are made to coincide even if the vehicle running state changes sharply, and the battery capacity can be minimized.
