ABSTRACT:
The shift lever interlock system combines a shift lever position signal, interlock actuator extend and retract signals and vehicle system input signals (e.g., representing the service brake, ignition key-in, ignition circuit and vehicle battery voltage level) in a logic control circuit to lock the shift lever in the "Park" position, except if the ignition key is not in the "Lock" position and the service brake is depressed (applied) or the voltage of the battery is too low. The interlock system is not actuated to lock the shift lever in position when the shift lever is in positions other than as retained in the "Park" position by the detent mechanism.
