Patent ID: 7832302

Claim:
A shift-by-wire shifter system comprising, in combination: a shifter lever assembly movable along a shift path; a gate profile defining a plurality of gear positions along the shift path; wherein the plurality of gear positions includes a park position; a gate pawl movable between a locking position wherein the gate pawl engages the gate profile to lock the shifter lever assembly in one of the plurality of gear positions and an unlocking position wherein the shifter lever assembly is movable along the shift path between the plurality of gear positions; a shifter actuator operatively coupled to the gate pawl to selectively move the gate pawl from the locking position to the unlocking position in response to an operator input so that the operator can selectively move the shifter lever assembly between the plurality of gear positions; a DTP lever movable toward the park position and engageable with the shifter lever assembly to move the shifter lever assembly to the park position; a spring member biasing the DTP lever toward the park position; a DTP lock assembly operatively coupled to the DTP lever to secure the DTP lever so that the shifter lever assembly is selectively movable along the shift path and to release the DTP lever so that the DTP lever moves the shifter lever assembly to the park position; and a DTP actuator operatively coupled to the gate pawl and the DTP lock assembly to selectively move the gate pawl to the unlocking position and release the DPT lock assembly so that the DTP lever moves the shifter lever assembly to the park position.
