Abstract:
A control section (10) of a vehicle steering system has a steer-by-wire mode, a power steering mode, and a transition mode. In the steer-by-wire mode, a steering actuator (19) is controlled for steering and a reaction force actuator (11) is controlled for reaction force. In the power steering mode, steering assistance control is performed with either of the steering actuator (19) and the reaction force actuator (11) caused to function as an assistance unit. In the transition mode, in a transition period from either of the steer-by-wire mode and the power steering mode to the other, the reaction force actuator (11) is controlled for reaction force.
