摘要： An electric power steering controller and a control method for assisting a driver during handling a steering wheel in a condition of a small road surface reaction torque of a tire by generating an auxiliary return torque for letting the steering wheel return to its original position. A first road surface reaction torque is estimated from a steering torque of a driver detected by a steering torque detector, a motor acceleration detected by a motor acceleration detector, and a motor current detected by a motor current detector. A second road surface reaction torque is estimated from a steering angle detected by a steering angle sensor, and a vehicle speed detected by a vehicle speed detector. Then, first and second auxiliary return torque signals of the steering wheel are computed from a road surface reaction torque, and, based on the computed result, a torque of the motor is controlled in direction so the steering wheel is returned to its original position.

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.
