摘要： A steer-by-wire system is provided with a driver operating unit, a turning unit, a backup mechanism, a steering reaction actuator, a wheel turning actuator and a controller. The backup mechanism mechanically connects the driver operating unit to the turning unit via a first shaft to transmit an input torque from the driver operating unit to the turning unit when the driver operating unit and the turning unit are mechanically connected by the backup mechanism. The steering reaction actuator applies a steering reaction torque to the driver operating unit. The wheel turning actuator applies a wheel turning torque to the turning unit via a second shaft. The controller controls the wheel turning actuator and the steering reaction actuator. The controller is configured to control the steering reaction actuator based on an operating parameter of the wheel turning actuator.

摘要： Under an automatic turning control, a steering controller defines a value of steering angle set according to a target turning angle of the automatic turning control, as a value of steering angle at which a reaction force is equal to 0. Thereby, the steering controller controls a steering reaction force on the basis of a difference between an actual steering angle and the value of steering angle at which the reaction force is equal to 0.
