Rear wheel steering control device

Abstract

Generally, the toe angle target speed limiting unit (A) adds a toe angle target value αsubjected to the primary delay to the result of a min-max processing the tracking error Δαby an adder (A) to output it as a toe angle target value αto a target current calculating unit (). However, in this toe angle target speed limiting unit (A), a switching control (steering direction change control) for generating a maximum value Δαas the toe angle target change quantity Δαand a hold control are made when a neutral position of the toe angle target value αwhich is prior to the toe angle command value αwhich is reached.
