Abstract

A traffic warning apparatus for a vehicle for warning traffic participants about a hazard region, having a sensor device that is embodied to sense a directional change of the vehicle, having an evaluation device that is embodied to identify a hazard region that ensues for other traffic participants as a result of the directional change of the vehicle, having a visualization device, mounted on the vehicle, that is embodied to visualize the hazard region for other traffic participants outside the vehicle. Also described is a traffic warning method for warning traffic participants about a hazard region.

Claims

1. A traffic warning apparatus for a vehicle for warning traffic participants about a hazard region, comprising:

a sensor device to sense a directional change of the vehicle;

an evaluation device to identify a hazard region that ensues for other traffic participants as a result of the directional change of the vehicle; and

a visualization device, mounted on the vehicle, to visualize the hazard region for other traffic participants outside the vehicle.

2. The traffic warning apparatus of claim 1, wherein the sensor device is configured to sense the directional change of the vehicle based on an actuation of a directional indicator of the vehicle.

3. The traffic warning apparatus of claim 1, wherein the sensor device (3) is configured to sense the directional change of the vehicle (2) on the basis of a steering angle (11) of the vehicle (2).

4. The traffic warning apparatus of claim 1, wherein the sensor device is configured to sense the directional change of the vehicle based on an acceleration of the vehicle (2).

5. The traffic warning apparatus of claim 1, wherein the sensor device is configured to receive a GPS signal and to sense the directional change of the vehicle based on the received GPS signal.

6. The traffic warning apparatus of claim 1, wherein the visualization device includes a projector that is configured to project the hazard region onto the roadway.

7. The traffic warning apparatus of claim 1, wherein the visualization device includes a light-emitting arrangement that is disposed on the vehicle.

8. The traffic warning apparatus of claim 1, wherein the visualization device includes a display that is disposed on the vehicle.

9. The traffic warning apparatus of claim 1, wherein the evaluation device is configured to identify the hazard region based on at least one of a length and a width of the vehicle.

10. A traffic warning method for warning traffic participants about a hazard region, the method comprising:

sensing, by a sensor device, a directional change of a vehicle;

identifying, by an evaluation device, a hazard region that ensues for other traffic participants as a result of the sensed directional change of the vehicle; and

visualizing the hazard region, by a visualization device mounted on the vehicle, for other traffic participants outside the vehicle.
