Abstract

The invention relates to an assembly module ( 20 ) for a motor vehicle ( 1 ), said assembly module having an optical sensor system ( 30 ) which is suitable a) for monitoring an activation region ( 22 ) outside of the motor vehicle ( 1 ) during an activation duration in order to identify a user's intention in the activation region ( 22 ), b) for providing a working signal in the case that a user's intention has been identified. According to the invention, auxiliary means ( 31, 43, 45, 80 ) are provided which help the user ( 10 ) to make the user's intention in the activation region ( 22, 28 ) known so that the working signal can be provided.

First claim

The invention claimed is:

1. An assembly module for a motor vehicle comprising an optical sensor system which is suitable
a) for monitoring an activation region outside the motor vehicle during an activation duration in order to identify a user's intention in the activation region,
b) for providing an operating signal in the case that the user's intention has been identified,
wherein
an auxiliary means is provided, which helps the user to make the user's intention in the activation region known so that the operating signal is provided,
the assembly module comprises a display element through which visible light can be emitted in order to make the activation duration visible for the user, wherein the visible light can be emitted variably by the display element,
a removal of a body part from the activation region must take place within a predefined removal duration so that the operating signal is provided, wherein the removal duration lies within the activation duration,
the display element is configured for a plurality of illumination states, and one illumination state serves as an information signal for the end of the activation duration, and
the display element changes to a different illumination state at the beginning of the removal duration.

2. The assembly module according to claim 1 ,
wherein
at least a position or a size of the activation region or a maximum activation duration is variable in particular by a predefined user action.

3. The assembly module according to claim 1 ,
wherein
the assembly module is suitable for renewed monitoring of the activation region in order to identify a user's intention to trigger an operating signal when a preceding maximum activation duration has elapsed without an identification of a user's intention.

4. The assembly module according to claim 3 ,
wherein
the renewed monitoring can be initiated by a predefined user action.

5. The assembly module according to claim 4 ,
wherein
the predefined user action is at least an input into a user menu, a triggering of a capacitive sensor or a predefined user action identifiable by the optical sensor system, in particular at least a predefined gesture within a perception range of the optical sensor system or a movement into the or out from the perception range of the optical sensor system.

6. The assembly module according to claim 1 ,
wherein
the assembly module can be transferred into a learning mode in which the assembly module learns at least the position to be changed or the size of the activation region or the length to be changed of a maximum activation duration.

7. The assembly module according to claim 1 ,
wherein
various positions of the activation region are fixedly predefined in the optical sensor system, wherein in particular the sequence in which the activation region changes the position is fixedly predefined.

8. The assembly module according to claim 1 ,
wherein
the display element has a plurality of lighting elements wherein in each case one or a plurality of lighting elements are fixedly assigned to the different positions of the activation region.

9. The assembly module according to claim 1 ,
wherein
the assembly module is suitable for determining the position of the user and the direction in which the user has to move towards the activation region, and for triggering a discernible, in particular visible, audible or perceptible signal for the user in order to lead the user to the activation region.

10. The assembly module according to claim 1 ,
wherein
the assembly module has means by means of which the discernible, in particular visible, audible or perceptible signal can be generated for the user in order to lead the user to the activation region, wherein the assembly module in particular comprises at least lighting elements or a loudspeaker.

11. The assembly module according to claim 1 ,
wherein
the optical sensor system comprises a monitor configured to evaluate images which have been recorded by the optical sensor.

12. The assembly module according to claim 1 ,
wherein
the optical sensor system comprises the optical sensor in order to receive light from the activation region and the optical sensor system comprises a light module having at least one light source for emitting light, wherein in particular the light source is configured to emit light in the non-visible range.

13. The assembly module according to claim 1 ,
wherein
the optical sensor comprises an image sensor with pixels, wherein during the monitoring of the activation region only that part of the pixels is evaluated which images the activation region, wherein in particular different pixels are evaluated according to the position of the activation region.

14. The assembly module according to claim 1 ,
wherein
the display element is configured to make visible an end face of the activation region on the ground surface on which the motor vehicle is standing.

15. The assembly module according to claim 1 ,
wherein
the optical sensor system is suitable for obtaining before step a) a signal that the authorized user is authorized and then instigating the monitoring of the activation region.

16. The assembly module according to claim 1 ,
wherein
the optical sensor system is suitable for monitoring prior to authentication a detection region lying outside the motor vehicle and in the case of identifying the user in the detection region triggering a signal for starting an authentication check between an ID transmitter and an access control system of the motor vehicle.

17. The assembly module according to claim 1 ,
wherein
at least the optical sensor or the light module are configured to be used both for monitoring the detection region and also for monitoring the activation region, wherein in particular the detection region and the activation region lie in the perception range of the optical sensor system.

18. The assembly module according to claim 1 ,
wherein
the activation region lies inside the detection region, wherein in particular each position which can be adopted for the activation region lies inside the detection region.

19. The assembly module according to claim 1 ,
wherein
the intensity of the light emitted by the display element is dependent on the brightness of the ambient light, wherein in particular the brightness of the ambient light can be determined by a brightness sensor.

20. An authentication system comprising an access control system, an ID transmitter and the assembly module according to claim 1 .

21. A motor vehicle comprising:
the assembly module according to claim 1 ; or
an authentication system comprising the assembly module according to claim 1 .

22. The assembly module according to claim 1 , wherein the optical sensor system is configured to identify the user's intention by a predefined movement of a body part of the user into or out from the activation region.

23. A motor vehicle having an assembly module which comprises an optical sensor system which is suitable for
a) monitoring an activation region lying outside the motor vehicle during an activation duration in order to identify a user's intention in the activation region,
b) in the case of identifying the user's intention, providing an operating signal,
