Abstract: When the engine torque starts decreasing prior to disengagement of a clutch, the motor torque realMT is controlled to compensate for the deficiency in the engine torque tpsET due to the decrease in the engine torque. Further, the motor torque realMT is controlled to compensate for a deficiency in the engine torque tpsET after engagement of the clutch until increasing of the throttle opening is completed. By controlling the motor torque as such, the reduction in the engine torque tpsET can be compensated for by the motor torque realMT not only when the clutch is being disengaged but also prior to the disengagement of the clutch and after engagement thereof, thus preventing fluctuation in acceleration of the vehicle due to the increase and decrease in torque.
