Patent ID: 7292919

Claim:
In a steering control device equipped with: a turning mechanism including a turning actuator driving a position-controllable turning shaft; and a steering angle sensor detecting a steering angle θ of a steering wheel, a steering control device comprises: a turning displacement sensor detecting a turning displacement X (−X E ≦X≦+X E ) in said turning mechanism; and means for calculating a turning instruction value calculating an instruction value for a turning displacement in said turning mechanism based on said steering angle θ; wherein: said turning instruction value calculating means includes means for generating hysteresis characteristics calculating said instruction value X n when an absolute value |θ| of said steering angle θ exceeds a predetermined threshold value θ E corresponding to an upper limit X E of said turning displacement X, said instruction value X n based on: a vertical axis coordinate corresponding to said steering angle θ on a predetermined hysteresis loop with one side being a section of a line X n =+/−X E on a θ−X n plane; and a steering direction, either steering direction or restoring direction, of said steering wheel.
