<p>An anti-lock brake system (ABS) or an electro-pneumatic brake system (EBS) for a vehicle (26) is used to perform a function of the vehicle (26) when it is in reverse such as sounding an audible back-up alarm and/or lighting a back-up lamp. A sensor member (20, 72, 74) is mounted on an axle (22) of the vehicle and is used to determine the speed of rotation of the wheel (24) and to determine the direction of rotation of the wheel (24). A controller (92) processes information from the sensor member (20, 72, 74) regarding the wheel speed and the direction of wheel rotation.</p> |
