Transmission shift assembly for a vehicle and a method of monitoring the same

摘要

The present invention provides for a transmission shift assembly for a vehicle and methods of monitoring and controlling the same. The transmission shift assembly includes a transmission having a shift position member movable between a plurality of gear positions, an actuator configured to move the shift position between the gear positions, and a linkage coupled to the actuator and movable between a plurality of positions in response to movement of the actuator. The assembly further includes a controller to control the actuator, an ignition to receive a key, and at least one key sensor positioned within the ignition and configured to transmit a signal to the controller upon sensing removal of the key, the controller controlling the actuator to move the shift position member to a predetermined gear position upon receiving the signal from the key sensor that the key has been removed from the ignition.

1. A transmission shift assembly for a vehicle, said assembly comprising:
a transmission having a shift position member movable between a plurality of gear positions; an actuator connected to the shift position member to move the shift position between the plurality of gear positions; a linkage coupled to said actuator and movable between a plurality of positions in response to movement of said actuator; a controller to control the actuator; an ignition configured to receive a key, the key moveable between a first position where the key is inserted in the ignition and a second position where the key is removed from the ignition; and at least one key sensor positioned within the ignition and configured to transmit a signal to the controller upon sensing of the second position, the controller controlling the actuator to move the shift position member to a predetermined gear position upon receiving the signal from the key sensor that the key has been removed from the ignition the controller being disabled from moving the shift position member to the predetermined gear position if the shift position member is in a neutral position.
