Abstract
An automatic transmission shifter assembly comprises a shift lever support configured for attachment to a vehicle, a shift lever mounted to the shift lever support to shift between transmission gear settings; a brake transmission system interlock (BTSI) comprising a shift lever control member controllable by actuation of a solenoid or other powered actuator to selectively block the shift lever from moving out of the PARK position. An electronic ignition switch, an ignition actuator and an ignition key interlock are mounted to the shift lever support. The ignition key interlock comprises an interlock member controllable by the ignition actuator to selectively block the solenoid from moving the shift lever control member to the unblock position.
Claims18
An automatic transmission shifter assembly comprising:
- a shift lever support configured for attachment to a vehicle, the shift lever support comprising a unitary molded plastic housing component;
- a shift lever mounted to the unitary molded plastic housing component to shift between a plurality of gear shift positions including at least, in any order, PARK, NEUTRAL and DRIVE positions;
- a brake transmission system interlock (BTSI) mounted to the unitary molded plastic housing component and comprising a powered actuator and a shift lever control member controllable by actuation of the powered actuator to apply force to control the portion of the shift lever control member in at least one of the positions including at least
- a shift lever block position in which the shift lever control member is positioned to block the shift lever from moving out of the PARK position, and
- a shift lever unblock position in which the shift lever control member is not positioned to block the shift lever from moving out of the PARK position;
- an electronic ignition switch mounted to the unitary molded plastic housing component and having conditions including at least
- an IGNITION condition corresponding to ignition of a vehicle's power system, and
- a NON-IGNITION condition;
- an ignition actuator mounted to the unitary molded plastic housing component and operative to control the condition of the electronic ignition switch, the ignition actuator having actuator conditions including at least
- an actuator IGNITION condition corresponding to the IGNITION condition of the electronic ignition switch, and
- an actuator NON-IGNITION condition corresponding to the NON-IGNITION condition of the electronic ignition switch;
- and
- an ignition key interlock mounted to the unitary molded plastic housing component and comprising an interlock member controllable by the ignition actuator to move between at least:
- a block position in which the interlock member is positioned to block the shift lever control member from the shift lever unblock position, and
- an unblock position in which the interlock member is positioned not to block the shift lever control member from the shift lever unblock position.
An automatic transmission shifter assembly for controlling the gear setting of a motor vehicle transmission having at least park, neutral and drive gear settings, comprising:
- a shift lever support configured for attachment to a vehicle, the shift lever support comprising a unitary molded plastic housing component having longitudinally and laterally extending segments including at least
- a pair of laterally spaced segments with a shift lever throw-space therebetween, and
- an ignition key socket segment;
- a shift lever pivot pin extending at least between the pair of laterally spaced segments;
- a shift lever pivotally mounted to the shift lever pivot pin to shift between a plurality of gear shift positions including at least, in any order, PARK, NEUTRAL and DRIVE positions corresponding to park, neutral and drive transmission settings, respectively, the shift lever comprising a shift lever shaft and a pivot structure attached at a lower end of the shift lever shaft, at least a portion of the shift lever shaft and pivot structure being positioned in the shift lever throw-space;
- a brake transmission system interlock mounted to the unitary molded plastic housing component and comprising a solenoid and a shift lever control member controllable by actuation of the solenoid in at least one of:
- a shift lever block position in which the shift lever control member is positioned to block the shift lever from moving out of the PARK position, and
- a shift lever unblock position in which the shift lever control member is not positioned to block the shift lever from moving out of the park position;
- an electronic ignition switch mounted to the unitary molded plastic housing component and having at least an ON condition corresponding to a vehicle's power system running, a LOCK condition corresponding to a vehicle's power system not running, and an IGNITION condition corresponding to ignition of a vehicle's power system;
- an ignition key socket mounted to the ignition key socket segment, configured to receive a key and with a key received therein is rotatable between at least a LOCK position, an ON position and an IGNITION position to control the condition of the electronic ignition switch between the LOCK condition, the ON condition and the IGNITION condition, respectively;
- and
- an ignition key interlock mounted to the unitary molded plastic housing component and comprising a key interlock lever controllable by movement of the ignition key socket to move between at least:
- a block position in which a key interlock lever is positioned to block the brake transmission system interlock from the shift lever unblock position, and
- an unblock position in which a key interlock lever is not positioned to block the brake transmission system interlock from the shift lever unblock position.
