ABSTRACT:
In a "steer-by-wire" vehicle steering control system which steers steerable wheels with a powered actuator according to an input signal obtained from a sensor associated with a steering wheel, a secondary actuator is coupled to the steering wheel for the purpose of giving the operator of the vehicle a reaction force. The reaction force on the steering wheel is sharply increased or oscillated when a limit of the angular displacement of the steering wheel has been reached for the purpose of allowing the vehicle operator to know how far the steering wheel has been turned. The limit of the angular displacement of the steering wheel typically corresponds to the maximally steered condition of the steerable wheels.
