Vehicle steering apparatus with anti-steer security device
Abstract:
A steering apparatus (10) comprises a steering feel motor (14) that is operatively connected to a steering shaft (16) of the vehicle (12). A sensor (20) detects operator applied steering inputs to the steering shaft (16) and outputs a steering signal indicative of the monitored operator applied steering inputs. A controller (28) receives the steering signal and, in response to the received steering signal, controls energization of the steering feel motor (14). A security device (38) is operatively connected to the controller (28) and is actuatable for providing a lock steering signal to the controller (28). The controller (28), in response to the lock steering signal, enters a lock steering mode in which the controller (28) controls energization of the steering feel motor (14) to counterbalance all operator applied steering inputs and thereby prevent steering of the vehicle (12).
