Electric power steering device

Abstract:

Even in the case that the steered wheels are turned by an actual turning angle due to a disturbance from the road surface, and the steering shaft, which is mechanically connected to the steered wheels, attempts to rotate, a command current to an assist motor is set so that the actual turning angle becomes a corrected target turning angle. The force (torque) that attempts to cause rotation of the steering shaft due to the disturbance input from the road surface is instantaneously canceled by the assist motor.
