Obstacle avoidance system for a camera arm for observing traffic to the rear of a vehicle

1. An obstacle avoidance system for a camera arm configured to observe traffic to the rear of a vehicle, the vehicle having bodywork, the system comprising:

the camera arm having a camera; and

a guide rail arranged on an external surface of the vehicle and extending between an external lateral surface of the bodywork of the vehicle and an external roof surface of the bodywork of the vehicle,

wherein the camera arm is arranged on the guide rail so as to be slidable along the guide rail back and forth between a position of rest on the roof surface and a working position on the lateral surface,

wherein in the working position the camera arm and camera extend laterally outward from the external lateral surface of the bodywork and in the position of rest the camera arm does not extend vertically so that the camera arm and camera are substantially flat on the roof surface.

2. The obstacle avoidance system as claimed in claim 1 , further comprising:

a slide connected to the camera arm and arranged on the guide rail so as to be slidable along the guide rail.

3. The obstacle avoidance system as claimed in claim 2 ,

wherein:

the guide rail has a first guide rail and a control cam, and

the first guide rail is configured to guide the camera arm along the guide, and the control cam is configured to control an alignment of the camera arm along the first guide rail.

4. The obstacle avoidance system as claimed in claim 3 , wherein the slide has a bearing point on which the camera arm is rotatably mounted at a first connecting point of the camera arm.

5. An obstacle avoidance system for a camera arm configured to observe traffic to the rear of a vehicle, the vehicle having bodywork, the system comprising:

the camera arm having a camera; and

a guide configured so as to extend from a lateral surface of the bodywork of the vehicle to a roof surface of the bodywork of the vehicle,

wherein the camera arm is arranged on the guide so as to be slidable along the guide back and forth between a position of rest on the roof surface and a working position on the lateral surface,

a slide connected to the camera arm and arranged on the guide so as to be slidable along the guide, the guide has a first guide rail and a control cam, and

the first guide rail is configured to guide the camera arm along the guide, and the control cam is configured to control an alignment of the camera arm along the first guide rail,

a rider arranged on the control cam,

wherein the slide has a puller configured to connect the at least one rider to the camera arm at a second connecting point of the camera arm via a deflection point arranged on the slide,

wherein the slide has a bearing point on which the camera arm is rotatably mounted at a first connecting point of the camera arm.

6. The obstacle avoidance system as claimed in claim 5 , wherein the distance between the control cam and the vehicle varies over the length of the first guide rail.

7. The obstacle avoidance system as claimed in claim 6 , wherein the slide has an opening in which the rider is movably arranged.

8. The obstacle avoidance system as claimed in claim 7 , further comprising:

a stop having a latch, wherein, in the working position (A), the camera arm bears against the stop and is fastened to the stop by the latch.

9. The obstacle avoidance system as claimed in claim 1 , further comprising:

at least one surroundings sensor configured to determine surroundings data which relate to the surroundings of the vehicle;

a drive device configured to move the slide along the guide rail; and

a controller configured to control the drive device in accordance with the determined surroundings data so as to move the slide along the guide rail.

10. A vehicle having the obstacle avoidance system for a camera arm as claimed in claim 1 .
