Abstract: A steering system for an automotive vehicle is disclosed. The steering system includes, in some embodiments, a steering shaft, a steering column jacket encircling at least a portion of the steering shaft, an emulator enclosed within a housing, the emulator coupled to the steering shaft, and a travel limiter assembly enclosed within the housing and coupled with the steering shaft, the travel limiter assembly comprising at least one rotational member having a pin and a groove configured to receive the pin, the groove including a stop portion. In some embodiments, the at least one rotational member and at least a portion of the steering shaft rotates within the housing and the pin travels within the groove until the pin encounters the stop portion after a predetermined degree of rotation of the steering shaft.

Abstract: Methods and systems are provided for monitoring steering gear overtravel in rack and pinion steering systems. The provided systems and methods introduce a change in the length of the fastener that attaches an inner tie rod ball joint housing within a steering gear rack bar. The provided systems and methods also monitor the disengagement of that fastener (also referred to as overtravel and as rack travel) to generate flags and provide them to the Controller Area Network (CAN) bus of the vehicle.
