Abstract
A steering device for a vehicle has: a target wheel steering angle production unit for producing a target wheel steering angle on the basis of a detected steering wheel angle; a wheel steering angle control unit for controlling steering angles of wheels turned for steering so that a detected wheel steering angle and a target wheel steering angle coincide with each other; a target reaction production unit for producing a target reaction on the basis of the steering wheel angle; a first reaction torque control unit for controlling a reaction torque produced in the steering wheel by driving a reaction control mechanism so that the reaction torque and the target reaction coincide with each other; and a second reaction torque control unit for compensating an output from the wheel steering angle control unit so that the reaction and the target reaction torque coincide with each other.
