Abstract
In a steer-by-wire steering system for a vehicle, a control unit () controls an operation of a steering actuator to cause the steered angle of wheels to be in a prescribed relationship to a steering angle, and an operation of the reaction force actuator () including a pair of reaction force motors () to cause the reaction force to be a value (Tt) corresponding to a steered state of the wheels, wherein the control unit is provided with a failure detection unit () configured to detect failures of the reaction force motors, and upon detecting a failure of one of the reaction force motors, progressively reduce an output (Tta) of the other reaction motor to a prescribed limit value (TL).
