Vehicle steering system and method for controlling vehicle direction through differential braking of left and right road wheels

摘要

A vehicle steering system in which brake steering forces intervene in the manual steering function wherein brake steering can be used to control the lateral position of a vehicle to supplement manual steering efforts, the system including brake controls for wheel brakes at the left and right sides of the vehicle which develop differential brake forces that result in a change in vehicle lateral position, the lateral position that is developed forming an input for a feedback regulator and brake controller, the magnitude of lateral position errors determining the brake forces that affect yaw rate and lateral position.
