Rear wheel steering control system

摘要

In a rear wheel control system for a four wheeled vehicle that includes a feedback controller (125) and a integral controller (124), the control system further comprises a reset control unit (120) for canceling the integrated value of the deviation under a prescribed operating condition of the control system. Thereby, a steady state deviation between an actual toe angle of a vehicle can be minimized owing to the control action of the integral controller without the disadvantage of an excessive overshoot which the integral control may bring under certain conditions. Therefore, the rear wheel steering control system enables an actual toe angle of a vehicle to favorably follow a target toe angle without causing an excessive overshoot under all conditions.
