摘要： An automatic steering apparatus that can suppress steering wheel vibration and that can also smooth angular control. In the automatic steering apparatus, a motor that steers steered wheels is controlled by a control unit. Information from an angle sensor that generates a signal that corresponds to a steering angle of the steered wheels is sent to the control unit. The control unit corrects a target steering angle of the steered wheels such that angular acceleration of the target steering angle is less than or equal to a limiting value. The control unit controls the motor such that the steering angle of the steered wheels tracks the corrected target steering angle based on the information from the angle sensor.

摘要： In an electric power steering control system, a road surface reaction torque estimator estimates a road surface reaction torque on the basis of steering wheel angle. A neutral point learning unit and a neutral point compensator learn a neutral point of the steering wheel on the basis of the road surface reaction torque with respect to the steering wheel angle. A return torque for returning the steering wheel to the neutral point is computed from a difference between a current angle of the motor and the learned neutral point. As a result, the steering wheel returns to the neutral point under the current driving condition without application of any force to the steering wheel by the driver.
