摘要：<p>PURPOSE:To obtain control equipment of an automobile system for driving a motor, while preventing a phenomenon of vibration due to a shaft torsion which occurs at the time of start and acceleration. CONSTITUTION:A vehicle model speed is computed by using a vehicle model 15 receiving a torque command tauR as an input and simulating a vehicle, and a compensating torque tauV containing a vibration component is calculated by a torque compensating circuit 16 by using the vehicle model speed and a motor speed. The torque command tauR is determined by using this compensating torque tauV an induction motor 2 is controlled by the torque command tauR and thereby an electric vehicle is driven. Accordingly, an effect that acceleration and deceleration can be executed while suppressing vibration at all times without using a vehicle speed sensor or the like and thus control equipment of the automobile being excellent in operability can be obtained by a simple hardware construction, is produced.</p>
