Abstract
An electric parking brake control system for automatically controlling one or more parking brakes in a vehicle. The parking brake control system includes an electric brake switch in communication with a low-pressure switch for automatically applying the parking brakes. The electric brake switch is preferably a latching type mechanism, which is capable of controlling a solenoid air valve external to the vehicle cab. The low-pressure switch automatically monitors an air reservoir for a low-pressure condition. The electric brake switch incorporates a time delay upon release of the switch, in order to prevent inadvertent application of the parking brakes due to a momentary loss of vehicle electrical power.
