摘要：A vehicle control system that selectively provides rear-wheel steering toprevent a vehicle-trailer from jackknifing during a back-up maneuver. The system sensesa steering angle of the vehicle, a speed of the vehicle and a hitch angle between the

vehicle and the trailer. The system calculates an equilibrium hitch angle that is a steady-state hitch angle position based on the steering angle and the vehicle speed, and apseudo-equilibrium hitch angle that is a steady-state hitch angle at a maximum rear-wheel steering input based on the steering angle and the vehicle speed. The system thendetermines whether the rear-wheel steering should be provided based on a

predetermined relationship between the sensed hitch angle, the equilibrium hitch angleand the pseudo-equilibrium hitch angle.
