Provided is a control device for a steer-by-wire steering mechanism, the control device including: a tire lateral force detection unit configured to detect tire lateral forces acting on left and right wheels; and a toe angle control unit configured to control toe angles of left and right wheels independently of each other such that the detected tire lateral forces become target lateral forces. Not during deceleration, the toe angle control unit sets target lateral forces FLt and FRt such that the total sum of the left and right target lateral forces is not changed and the total sum of absolute values thereof is decreased, and during deceleration, the toe angle control unit sets the target lateral forces FLt and FRt such that straight traveling stability can be obtained.
