Generally, the toe angle target speed limiting unit (84A) adds a toe angle target value αT2P subjected to the primary delay to the result of a min-max processing the tracking error ΔαT1A by an adder (58A) to output it as a toe angle target value αT2A to a target current calculating unit (86). However, in this toe angle target speed limiting unit (84A), a switching control (steering direction change control) for generating a maximum value ΔαTmax as the toe angle target change quantity ΔαT2 and a hold control are made when a neutral position of the toe angle target value αT2A which is prior to the toe angle command value αT1 which is reached.
