Abstract
An electronic control unit inputs a side slip angle β of a vehicle body. The unit calculates a dynamic zero point δo for reducing a lateral force generated in the vehicle due to the side slip angle β of the vehicle body. The unit calculates a steering angle δa, which is represented by the difference between the dynamic zero point δo and a steering angle δ detected by a steering angle sensor. The unit calculates a reaction torque Tz having a predetermined relation with the steering angle δa. The unit drives and controls an electric motor to generate the calculated reaction torque Tz. Thus, the unit guides a driver to a proper steering-wheel rotating direction.
