PROBLEM TO BE SOLVED: To absorb a torque step difference generated by an engine by calculating a torque step difference value generated by the engine according to demand torque to the engine, an operating condition of the engine, and an engine control switching signal, and controlling an electric motor according to the torque step difference. SOLUTION: In control in the case where combustion of an engine 101 is changed from stoichiometric air-fuel ratio combustion to lean combustion, an engine control switching signal is outputted according to accelerating operation of a driver and the like by engine control switching means 107, and an air-fuel ratio is changed following with the engine control switching signal and a demand torque by an engine control means 105. A torque step difference is calculated from the demand torque, an engine operating condition, and the engine control switching signal by a torque step difference calculating means 106, and an electric motor 102 is controlled by a motor control means 104 so as to offset the torque step difference. A composite torque of the engine 101 and the electric motor 102 is set to a constant value so as to solve disorder feeling applied on the driver. |
