Abstract

A method and apparatus for unlocking a trunk lid of a motor vehicle is suggested which ensures that a person in the interior of the trunk can free himself from this trunk. For this purpose, an unlocking handle is provided in the interior which, when it is operated and the vehicle is standing still, unlocks the trunk lid. If, when the unlocking handle is operated, the vehicle is driving, a delay time is started after whose expiration the trunk lid is released.

Claims

1. Method of unlocking a trunk lid of a vehicle, wherein, in an interior of the trunk, an unlocking handle is arranged,

wherein, when the unlocking handle is operated, the speed (v) of the vehicle is detected,

wherein, when it is detected that the vehicle is standing still, a release of the trunk lid takes place for opening the trunk lid, and

wherein, when a driving vehicle is detected, a definable delay time (tv) is started and, after the expiration of the definable delay time (tv), the trunk lid is released for opening.

2. Method according to claim 1, wherein for releasing the trunk lid, an adjusting element is triggered which operates a catch hook applied to the trunk lid.

3. Method according to claim 1, wherein the delay time (tv) can be adjusted as a function of the speed of the vehicle (v).

4. Method according to claim 1, wherein when the unlocking handle is operated, the driver receives information in the interior of the vehicle.

5. Method according to claim 2, wherein when the unlocking handle is operated, the driver receives information in the interior of the vehicle.

6. Method according to claim 3, wherein when the unlocking handle is operated, the driver receives information in the interior of the vehicle.

7. Method according to claim 4, wherein the driver information is indicated visually and/or acoustically.

8. Method according to claim 5, wherein the driver information is indicated visually and/or acoustically.

9. Method according to claim 6, wherein the driver information is indicated visually and/or acoustically.

10. Method for unlocking a trunk lid on a passenger motor vehicle, comprising:

manually operating a trunk lid opening handle from within a trunk interior space by a person located in said interior space,

detecting the vehicle speed, and

controlling unlatching of the trunk lid as a function of the vehicle speed such that the manual operating of the trunk lid opening handle will result in unlatching of the trunk lid only after a predetermined time when the vehicle speed is above a predetermined valve.

11. Method according to claim 10, comprising providing a signal to a vehicle driver when the trunk lid opening handle is operated and the vehicle is moving.

12. Method according to claim 10, wherein said predetermined time is varied as a function of the vehicle speed at the time the trunk lid opening handle is operated.

13. Method according to claim 11, wherein said predetermined time is varied as a function of the vehicle speed at the time the trunk lid opening handle is operated.

14. Apparatus for unlocking a trunk lid on a passenger motor vehicle, comprising:

a manually operable trunk lid opening handle in a trunk interior space for operation by a person located in said interior space,

means for detecting the vehicle speed, and

means for controlling unlatching of the trunk lid as a function of the vehicle speed such that the manual operating of the trunk lid opening handle will result in unlatching of the trunk lid only after a predetermined time when the vehicle speed is above a predetermined valve.

15. Apparatus according to claim 14, comprising means for providing a signal to vehicle driver when the trunk lid opening handle is operated and the vehicle is moving.

16. Apparatus according to claim 14, wherein said predetermined time is varied as a function of the vehicle speed at the time the trunk lid opening handle is operated.

17. Apparatus according to claim 15, wherein said predetermined time is varied as a function of the vehicle speed at the time the trunk lid opening handle is operated.
