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.

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 electric power steering controller including a motor for generating torque for assisting the steering torque of a driver to assist the steering force of a steering system. The controller includes a road reaction torque detector for detecting road reaction torque received by tires from the surface of a road, and a road detection torque addition control for controlling the torque of the motor based on the road reaction torque. The electric power steering controller enables the steering wheel to be returned to its starting point without adding torque in a direction in which the driver returns the steering wheel when the driver contgrols the steering wheel with the small road reaction torque of the tires, for example, when turning at an intersection at a low speed or when turning at a gently curved portion of a road at a high speed.
