Abstract
A secondary parking apparatus is provided for a vehicle having components of a parking brake system, components of an anti-lock brake system (ABS), and a manually-operable device. The secondary parking apparatus comprises an electronic controller arranged to (i) monitor the manually-operable device to detect an operator intent signal to apply parking brakes of the parking brake system, (ii) receive a combination of one or more signals indicative of a fault condition of the vehicle, and (iii) provide one or more control signals to be applied to components of the ABS to selectively exhaust air pressure from components of the ABS to atmosphere so that parking brakes of the parking brake system are applied to park the vehicle when both the operator intent signal and the combination of one or more signals indicative of a fault condition of the vehicle are detected.
