摘要： A power steering control system is provided with a road surface reaction torque detector in which a motor inertia torque is subtracted from a value obtained by adding steering torque and motor torque, and the value is passed through two stages of primary filters to obtain a road surface reaction torque. In such a computation, the inertia term of the steering wheel manipulation force does not depend on frequency and high frequency components do not bring about any unusually large steering wheel return force. Therefore, a driver can drive without difficulty in adapting to the power steering.

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.
