Automobile four=wheel steering control - adjusts tracking angle variation amplitude of auxiliary wheels dependent on steering angle and vehicle velocity

摘要

The automobile 4-wheel steering control has one pair of wheels steered directly in response to the rotation of the steering wheel, the remaining pair of wheels having a tracking regulation system. The vehicle velocity is monitored and used in conjunction with the steering angle signal obtained from the rotation of the steering wheel, to obtain the steering angle for the second set of wheels. Pref. the vehicle velocity is obtained from a wheel velocity signal, with the tracking regulation system allows a given wheel slip to be maintained. USE - For anti-locking braking system.
