ABSTRACT:
A four-wheel steering system includes a torque sensor, a first steering angle sensor, a vehicle speed sensor, a second steering angle sensor, a first DC motor, a second DC motor, and a controller. The torque sensor outputs a front-wheel steering force signal. The first steering angle sensor outputs a front-wheel steering angle signal. The vehicle speed sensor outputs a vehicle speed signal. The second steering angle sensor outputs a rear-wheel steering angle signal. The first DC motor supplies a torque to a front-wheel steering system. The second DC motor supplies a torque to a rear-wheel steering system. The controller outputs a rear-wheel steering force signal by detecting a current supplied to the second DC motor, and determines a control target value by receiving the front- and rear-wheel steering force signals and the front- and rear-wheel angle signals, and the vehicle speed signal.
