Vehicle steering control system and method of operating same

摘要

A vehicle is equipped with a rear wheel control device including hydraulic actuators for controllably turning rear wheels under influence of hydraulic fluid supplied thereto from a hydraulic pump. Turning the rear wheels is made in one of first and second directions which are opposite to each other, in response to steering effort applied to a steering wheel. The change-over operation of the rear wheel turning between the first and second directions takes place upon substantially stopping supply of the hydraulic fluid to the actuators, thereby preventing shock during the turning direction change-over operation.
