Abstract
In a vehicular steering system, a steering wheel (steering member) operated for steering and a steering operation mechanism are not mechanically coupled together, and the steering operation mechanism is driven by a steering operation motor. The vehicular steering system includes a reaction force motor that applies a reaction force to the steering member, and a reaction force motor control unit that controls the reaction force motor. The reaction force motor control unit includes a torque limiter that limits a current flowing through the reaction force motor to a predetermined value or smaller during automatic operation.
