Electronic park lock
First Claim
1. An electronic shifter interlock for an automotive vehicle having a shift lever which is pivotally mounted for transmission operating mode selection and which includes a spring-biased, axially movable core rod forming part of a detent-type PARK lock wherein the interlock further comprises:
- an electromagnetic actuator housing fixedly mounted on the shift lever for pivotal movement therewith; and
an electromagnetic actuator within the housing and operatively engaging the core rod to alternatively inhibit and enable operation of the PARK lock.

Abstract
An electronic transmission shifter interlock system in which an electronic module is mounted directly on a shift lever for pivotal movement therewith. The module contains two electromagnetic devices which operate on the spring-biased, shift lever core rod to control the PARK lock release so as to inhibit and/or enable operation of the shift lever according to the status of the ignition lock and the position of the brake pedal. The interlock module is electrically coupled with the ignition lock to prevent the ignition key from being removed while the shift lever is other than the PARK position.

5. An electronic shifter interlock system for an automotive vehicle having a lever-operated shifter of the type having a release mechanism which must be actuated before the shift lever can be effectively operated, comprising:
-
a shift lever mounted for pivotal movement between a PARK position and a series of drive positions; a core rod and a stub shaft mounted within said lever for axial reciprocal motion between a shift lock position and a shift release position, the stub shaft having first and second notches formed therein; a first electromagnetic device having a normally extended bolt engaging the first notch to inhibit axial movement of the rod away from the shift lock position but energizable to retract said bolt to enable movement of the rod to the shift release position; a second electromagnetic device having a movable bolt held in engagement with the second notch to inhibit axial movement of the rod away from the shift lock position only when the second electromagnetic device is energized; the first electromagnetic device being operatively connected to a vehicle ignition system to be energized only when the ignition system is activated; and the second electromagnetic device being operatively connected to another vehicle system to be energized only when a predetermined condition in said system is satisfied. - View Dependent Claims (6, 7, 8, 9, 10, 11, 12, 13)
