ABSTRACT:
A ignition-controlled parking brake interlock is provided for a vehicle. The parking brake operating lever is latched in brake-applied positions by engagement of a lever-mounted pawl with fixed sector. A solenoid is movable between positions blocking and unblocking movement of the vehicle ignition to OFF. A lock bar carried by the lever is movable by a second solenoid between positions blocking and unblocking movement of the pawl to release the lever. In one embodiment, a brake lever position switch and a switch operated by the second solenoid control solenoid operation to prevent ignition key removal unless the parking brake is applied and to prevent parking brake release unless the key is inserted and the ignition moved to RUN. In another embodiment, bi-stable solenoids are controlled by a controller that is provided with high and low current inputs from branch circuits that include control switches operated by ignition position and parking brake lever position.
