Abstract
A steering control system includes a steering-motor for turning wheels, a reaction-force-motor for applying a reaction torque to a steering of the vehicle, and a controller. The controller calculates a turning angle based on a first-characteristic representing a relationship of the turning angle to a steering angle, and calculates a reaction torque based on a second-characteristic representing a relationship of a reaction torque to the steering angle. The controller changes the first-characteristic from a characteristic corresponding to a first-state to a characteristic corresponding to a second-state in response to a change in the state of the vehicle from the first-state to the second-state. The controller maintains the second-characteristic at the characteristic corresponding to the first-state when the state of the vehicle changes from the first-state to the second-state in the case where the steering angle is steered to a steering limit corresponding to an upper limit of the turning angle.
