Abstract: A steering apparatus (10) for turning steerable wheels of a vehicle having first and second sets (14 and 16) of steerable wheels comprises a first steering gear (22) actuatable, in response to rotation of a handwheel (110), to effect turning of the first set (14) of steerable wheels. The steering apparatus (10) also comprises second and third steering gears (24 and 26), each of which is independently actuatable to effect turning of the second set (16) of steerable wheels and thereby providing redundancy for turning of the second set (16) of steerable wheels. A sensor (112) senses a steering position of the first set (14) of steerable wheels and provides a steering signal indicative of the sensed steering position. A controller (114) receives the steering signal and, in response to the steering signal, controls actuation of the second and third steering gears (24 and 26).

Abstract: A ball joint assembly (10) comprises a socket (12) with a chamber (18), an opening extending through a first axial end (20) of the socket (12), and electrically conductive structure (60) closing the second axial end (22) of the socket (12). An electrically conductive ball stud (30) has a head portion (32) that is received in the chamber (18) and a shank portion (34) that extends through the opening. An electrically conductive bearing member (40) is received in the chamber (18) and provides an electrical connection between the structure (60) and the ball stud (30). An electrically non-conductive biasing member (50) is interposed between the structure (60) and the bearing member (40) and urges the bearing member away from the structure such that, in response to a predetermined amount of wear, the electrical connection between the structure (60) and the ball stud (30) is discontinued.

Abstract: A method for controlling a steering apparatus (10) of a vehicle produces an error signal (128) by subtracting a hand wheel torque (118) and a column torque (126) from a desired operator torque (112) to be applied to a hand wheel (14) of the vehicle. A controller (102) receives at least one vehicle condition signal (106, 108, 110) and determines the desired operator torque (112). Inertia (116) and acceleration (120) of the hand wheel (14) of the vehicle are determined. A hand wheel torque (118) is calculated by multiplying the inertia (116) of the hand wheel (14) with the acceleration (120) of the hand wheel (14). The column torque (126) is determined by measuring torque across a torsion bar (50).
