Abstract

A device is provided for preventing a collision between a pivoting element of a vehicle, with an obstacle located in its pivoting area, with a control unit which controls the pivoting movement of the vehicle pivoting element and with a lighting device which is coupled to the pivoting movement and emits light into the pivoting area. Depending on the reflection of the emitted light on the obstacle the control units intervenes in the pivoting movement.

Claims

1. A device for preventing a collision between a pivoting element of a vehicle and an obstacle located in a pivoting area, comprising:

a control unit configured to control a pivoting movement of the pivoting element; and

a lighting device coupled with the pivoting movement and configured to emit a light into the pivoting area,

wherein the control unit is configured to intervene in the pivoting movement based at least in part on a reflection of the light on the obstacle.

2. The device in accordance with claim 1, wherein the lighting device comprises a vehicle light.

3. The device in accordance with claim 2, wherein the vehicle light is a vehicle rear light.

4. The device in accordance with claim 1, wherein the lighting device is arranged on the pivoting element.

5. The device in accordance with claim 1, further comprising a recording device that is configured to record the reflection of the light on the obstacle.

6. The device in accordance with claim 5, wherein the recording device comprises a camera system.

7. The device in accordance with claim 5, wherein the light emitted into the pivoting area is configured to form a light pattern on the obstacle, and

wherein the recording device is configured to generate information that represents the light pattern, and

wherein an evaluation unit evaluates the information in determining if the control unit is to intervene in the pivoting movement.

8. The device in accordance with claim 7, wherein the evaluation unit evaluates a size of the light pattern formed on the obstacle.

9. The device in accordance claim 7, wherein the evaluation unit evaluates a shape of the light pattern formed on the obstacle.

10. The device in accordance with claim 1, wherein the control unit is configured to interrupt the pivoting movement if the reflection of the light indicates the collision.
