PROBLEM TO BE SOLVED: To correctly control the output of an internal combustion engine and a motor in response to required driving force. SOLUTION: A power train of a hybrid car is provided with an interrupter 3 provided between an internal combustion engine 2 and a motor 4, and controllable in transmission torque from the internal combustion engine 2 to the motor 4, and drives drive wheels from the motor 4 via a transmission 5. Against the power train, target torque is computed on a motor shaft based on the gear ratio of the transmission 5, a car speed, and the required drive force of the car, the target transmission torque of the interrupter 3 based on the target torque is determined, and the interrupter 3 is controlled so that the transmission torque of the interrupter 3 becomes the target transmission torque. The target motor torque of the motor 4 is determined by subtracting the target transmission torque from the target torque, the motor 4 is controlled so that the output torque of the motor 4 becomes the target motor torque. Thereby, the motor shaft target torque in response to the required drive force can be distributed to the internal combustion engine 2 and the motor 4 at an arbitrary rate, and the motor shaft torque can be correctly controlled in response to the required driving force. |
