ABSTRACT:
A service brake and shift lever interlock system for a vehicle is operably controlled by a logic control circuit to prevent movement of the shift lever from the "Park" position when the ignition switch is in the "Start" or "Run" position and the service brake pedal is in a brake release position (i.e., the vehicle brakes are not applied). The interlock system does not prevent movement of the shift lever from the "Park" position under other conditions when the ignition switch is in the "Start" or "Run" position. An ignition interlock system prevents movement of the shift lever from the "Park" position when the ignition switch is in the "Lock" position.
