More Information
Summary:There is provided a vehicle steering system including a steering mechanism (1) that drives a vehicle, a motor (2) that makes the steering mechanism (1) rotate, a steering angle sensor (4) that detects a steering angle, which is a rotation angle of the steering mechanism (1), and outputs a detected steering angle having a hysteresis with respect to the steering angle, a hysteresis estimation unit (6) that estimates a hysteresis estimation value corresponding to a difference between the steering angle and the detected steering angle, and a control unit (7) that controls the motor (2) in such a way as to be equal to a difference between the steering angle and a target steering angle, which is a target value of the steering angle, based on the target steering angle, the detected steering angle, and the hysteresis estimation value.
