摘要： An electric power steering device wherein mechanical friction is electrically provided. A steering torque value is detected by a steering torque sensor according to the operation of a steering wheel. An assist current value is calculated by an assist control section on the basis of the steering torque value. A target current value based on the assist current value is determined. For providing friction to the operation of the steering wheel, a friction control section and a friction torque value/current value conversion section generate a corrected steering torque value. A second corrected target current value is created by correcting a first corrected target current value by a friction current value. The corrected steering torque value is obtained by correcting the steering torque value by a friction torque value. The target current value is generated, resulting in a motor being subjected to driving control.

摘要： In a steering control system for controlling torque steer in a vehicle equipped with an electric power steering device and a torque split arrangement for individually controlling traction and/or braking force of right and left wheels, a difference in traction and/or braking force between the right and left wheels which may be produced by the torque split arrangement may give rise to torque steer depending on the geometry of the wheel suspension system of the vehicle. The control unit for the electric power steering device additionally receives an additional signal for providing an additional steering torque which is required for canceling the torque steer. Thus, the torque steer can be eliminated both economically and reliably without requiring to modify the wheel suspension system.

摘要： In a steering system which produces a reactive steering assist torque which tends to cancel any unintended or undesired behavior of the vehicle, the relationship between the steering angle and the vehicle behavior such as the yaw rate and the lateral acceleration reverses in sense depending on the traveling direction of the vehicle. To prevent the control unit for the steering system from producing any reactive steering assist torque which could worsen the behavior of the vehicle when the vehicle is traveling rearward, the control unit either eliminates or reverses the sense of the reactive steering assist torque when the vehicle is traveling rearward.
