Abstract

A power door actuation system for a vehicle door includes a power-operated presenter assembly fixed to one of the vehicle door and vehicle body and an auxiliary latch assembly fixed to the other one of the vehicle door and vehicle body. A latched relationship is maintained between the vehicle door and the vehicle body when the presenter assembly moves the door between a closed position and a deployed position.

First claim

What is claimed is:

1. A power door presenter system for a motor vehicle having a vehicle door moveable relative to a vehicle body between a closed position, a presented position, and a fully-open position, the system comprising:
a presenter assembly mounted to one of the vehicle body and the vehicle door, the presenter assembly including an extensible member moveable between a retracted position and an extended position, and a motor driven mechanism operable for powered movement of the extensible member, wherein powered movement of the extensible member between its retracted and extended position results in corresponding movement of the vehicle door between the closed position and the presented position;
a primary latch assembly mounted to the vehicle door and operable to releasably hold a primary striker mounted to the vehicle body when the vehicle door is located in the closed position, wherein the primary latch assembly is operable to release the primary striker prior to powered movement of the extensible member causing movement of the vehicle door from the closed position to the presented position; and
an auxiliary latch assembly operably mounted to one of the extensible member and the other one of the vehicle body and the vehicle door and having a latch mechanism and a latch release mechanism, and an auxiliary striker engageable with the latch mechanism and operably mounted to the other one of the extensible member and the other one of the vehicle body and the vehicle door for preventing movement of the vehicle door from the presented position to the fully-open position when the latch mechanism is engaged with the auxiliary striker,
wherein the latch release mechanism is actuatable for releasing the latch mechanism from the auxiliary striker so as to permit subsequent manual movement of the vehicle door by a user from the presented position to the fully-open position.

2. The power door presenter system of claim 1 , wherein the auxiliary striker is held by the latch mechanism such that powered movement of the extensible member between its retracted and extended position results in corresponding movement of the vehicle door between its closed position and the presented position.

3. The power door presenter system of claim 1 , wherein the auxiliary striker is mounted on the extensible member, and wherein the latch mechanism is mounted to the other one of the vehicle body and the vehicle door and includes a ratchet moveable between a striker capture position whereat the ratchet holds the auxiliary striker and a striker release position whereat the auxiliary striker is released, and a pawl moveable between a ratchet holding position whereat the pawl holds the ratchet in its striker capture position and a ratchet releasing position whereat the pawl permits the ratchet to move to its striker release position, wherein the latch release mechanism is actuated by the motor driven mechanism to move the pawl from its ratchet holding position into its ratchet releasing position, wherein the latch mechanism operates in a latched mode when the ratchet is located in its striker capture position for coupling the extensible member of the presenter assembly to the auxiliary latch assembly, and wherein the latch mechanism operates in an unlatched mode when the ratchet is located in its striker release position for uncoupling the extensible member of the presenter assembly from the auxiliary latch assembly.

4. The power door presenter system of claim 1 further comprising a control system for controlling release of the primary latch assembly in coordination with actuation of the motor driven mechanism.

5. The power door presenter system of claim 4 , wherein the control system includes a sensor operable to detect when the vehicle door is under manual control of the user so as to control actuation of the latch release mechanism for releasing the auxiliary striker from the latch mechanism when the vehicle door is deployed to the presented position.

6. The power door presenter system of claim 5 , wherein the auxiliary latch assembly further comprises a power-operated latch release actuator controlled by the control system for actuating the latch release mechanism.

7. The power door presenter system of claim 1 , wherein the auxiliary latch assembly further comprises a manually-actuated release actuator for actuating at least one of the latch mechanism and the latch release mechanism for releasing the auxiliary striker from the latch mechanism in response to a manual input from the user.

8. The power door presenter system of claim 1 , wherein the motor driven mechanism includes an actuator housing mounted to the vehicle body, an electric motor supported by the actuator housing, and a spindle drive unit having a rotary drive member rotatably driven by the motor, wherein rotation of the drive member in a first direction causes translation of the extensible member in a first direction from its retracted position toward its extended position, and wherein rotation of the drive member in a second direction causes translation of the extensible member in a second direction from its extended position toward its retracted position.

9. The power door presenter system of claim 8 , wherein the extensible member is a drive nut in threaded engagement with the rotary drive member, and wherein the auxiliary striker is fixed to the drive nut.

10. The power door presenter system of claim 1 , wherein the presenter assembly is mounted to the vehicle body, the auxiliary striker is mounted to the extensible member, and the latch mechanism is mounted to the vehicle door.

11. The power door presenter system of claim 1 , wherein the auxiliary striker is mounted to the other one of the vehicle body and the vehicle door, wherein the latch mechanism is mounted to the extensible member and includes a latch hook mounted to the extensible member, wherein the auxiliary striker is moveable between a striker capture position whereat the latch hook holds the auxiliary striker and a striker release position whereat the auxiliary striker is released, and wherein the latch release mechanism is operable to move the auxiliary striker from its striker capture position to its striker release position.

12. The power door presenter system of claim 11 further comprising a control system for controlling release of the primary latch assembly in coordination with actuation of the motor driven mechanism.

13. The power door presenter system of claim 12 , wherein the control system includes a sensor operable to detect when the vehicle door is under manual control of the user so as to control actuation of the latch release mechanism for releasing the auxiliary striker from the latch mechanism when the vehicle door is deployed to its presented position.

14. The power door presenter system of claim 13 , wherein the auxiliary latch assembly further comprises a power-operated latch release actuator controlled by the control system for actuating the latch release mechanism.

15. The power door presenter system of claim 11 further comprising a manually-actuated striker release mechanism for disengaging the auxiliary striker from the latch hook in response to a manual input from the user.

16. The power door presenter system of claim 15 , wherein the manually-actuated striker release mechanism is operable when the latch hook is located in the striker capture position to move the auxiliary striker to a position displaced from the latch hook.

17. The power door presenter system of claim 11 , wherein the motor driven mechanism includes an actuator housing mounted to the vehicle b
