Original Abstract Submitted

A steer-by-wire steering system for a vehicle includes: a reaction force actuator to which an operation member is connected such that the reaction force actuator is moved by the operation member, the reaction force actuator including a power source by which the reaction force actuator applies an operation reaction force to the operation member; a steering actuator to which a wheel is connected, the steering actuator including a power source by which the steering actuator steers the wheel; and a controller configured to control the reaction force actuator and the steering actuator. The controller is configured to execute, for the reaction force actuator, the steering actuator, or both the reaction force actuator and the steering actuator, a neutral position setting processing of setting a neutral position in a motion range and a motion position hold processing of holding a motion position at the neutral position by the power source.
