It is determined that assisting is required when a deviation of a target matching engine speed and a current engine speed is equal to or more than a predetermined value, and for a predetermined period of time since the time point at which it is determined that assisting is required, a target assist engine speed is set at a high rotation target matching engine speed which is more than the target matching engine speed, and thereafter the target assist engine speed is set gradually closer to the target matching engine speed, and an assist torque command value is output to the generator assisting output of the engine, and the engine speed is controlled, so that the engine speed attains the target assist engine speed.
