Abstract

A method is described for the plausibility checking for wrong-way travel of a motor vehicle on a directional roadway of the road, at least one visual road feature being recorded and, with the aid of the visual road feature, it is determined whether the motor vehicle is located on a directional roadway. Furthermore, a control and recording device for the plausibility checking for wrong-way travel of a motor vehicle on a directional roadway of a road is provided, having a recording arrangement for recording at least one visual road feature and a determining arrangement for determining, with the aid of the visual road feature, whether the motor vehicle is located on a directional roadway.

Claims

1. A method for checking for wrong-way travel of a motor vehicle on a directional roadway of a road having at least two directional roadways that are structurally separated from each other, the method comprising:

recording, using an image sensor of the motor vehicle, at least one visual road feature of the road having the at least two directional roadways that are structurally separated from each other, the at least one visual road feature including at least one of;

a width of a component of the road, or a length of a component of the road;

comparing, using a control unit of the motor vehicle, the recorded width or length of the component of the road to a checking value, wherein the checking value is based on a standard regulation for the directional roadway, the checking value including at least one of;

a regulated width of the component of the road, or a regulated length of the component of the road;

determining, using the control unit, that the motor vehicle is located on the directional roadway of the road having the at least two directional roadways that are structurally separated from each other based on the comparing;

upon determining that the motor vehicle is located on the directional roadway, determining, using the control unit, that the motor vehicle is engaged in wrong-way travel based on a directionally dependent property of the at least one visual road feature of the road having the at least two directional roadways that are structurally separated from each other; and

upon determining that the motor vehicle is engaged in wrong-way travel, at least one of;

providing a warning to a driver the motor vehicle, or performing an intervention in the operation of the motor vehicle.

2. The method of claim 1, wherein the at least one visual road feature includes a lane width of a traffic lane.

3. The method of claim 1, wherein the at least one visual road feature includes a road sign.

8. The method of claim 1, wherein the image sensor includes at least one of:

a stereovideo camera of the motor vehicle, or a stereoimage camera of the motor vehicle.

12. The method of claim 1, wherein the determining whether the motor vehicle is engaged in the wrong-way travel is performed upon determining that the motor vehicle is located on the directional roadway.

13. The method of claim 1, wherein the at least one visual road feature includes a color of a road sign.

14. The method of claim 1, wherein the at least one visual road feature includes printed information on a road sign.

15. The method of claim 1, wherein the at least one visual road feature includes a width of a traffic lane marking.

21. The method of claim 1, wherein at least one dimension of the visual road feature includes at least one of:

a width of a traffic lane, a width of a line on the road, a length of a broken line on the road, or a length of an interruption of the broken line on the road.

4. A method for checking for wrong-way travel of a motor vehicle on a directional roadway of a road, the method comprising:

recording at least one visual road feature, the at least one visual road feature including at least one road sign;

determining, with the aid of the at least one visual road feature, whether the motor vehicle is located on a directional roadway; and

establishing the wrong-way travel based on a detection of a back side of the at least one road sign.

20. The method of claim 4, wherein the determining whether the motor vehicle is located on the directional roadway is based on a detection of a front side of the at least one road sign.

5. A device for checking for wrong-way travel of a motor vehicle on a directional roadway of a road having at least two directional roadways that are structurally separated from each other, the device comprising:

a recording arrangement to record at least one visual road feature of the road having the at least two directional roadways that are structurally separated from each other, the at least one visual road feature including at least one of;

a width of a component of the road, or a length of a component of the road; and

a controller to;

compare the recorded width or length of the component of the road to a checking value, wherein the checking value is based on a standard regulation for the directional roadway, the checking value being at least one of;

a regulated width of the component, or a regulated length of the component;

determine that the motor vehicle is located on the directional roadway of the road having the at least two directional roadways that are structurally separated from each other based on the comparing; and

upon determining that the motor vehicle is located on the directional roadway, determine that the motor vehicle is engaged in wrong-way travel based on a directionally dependent property of the at least one visual road feature of the road having the at least two directional roadways that are structurally separated from each other; and

upon determining that the motor vehicle is engaged in wrong-way travel, at least one of;

providing a warning to a driver the motor vehicle, or performing an intervention in the operation of the motor vehicle.

6. The device of claim 5, further comprising:

an interface to receive the checking value.

7. The device of claim 5, further comprising:

a memory for storing the checking value.

9. The device of claim 5, wherein the at least one visual road feature includes at least one of:

a lane width of a traffic lane, or a width of a lane marking.

10. The device of claim 5, wherein the at least one visual road feature includes a road sign.

11. The device of claim 5, wherein the controller performs the determining whether the motor vehicle is engaged in the wrong-way travel upon determining that the motor vehicle is located on the directional roadway.

16. A device for checking for wrong-way travel of a motor vehicle on a directional roadway of a road having the at least two directional roadways that are structurally separated from each other, the device comprising:

an image sensor to record at least one visual road feature of the road having the at least two directional roadways that are structurally separated from each other, the at least one visual road feature including at least one of;

a width of a component of the road, or a length of a component of the road; and

a controller to;

compare the recorded width or length of the component of the road to a checking value, wherein the checking value is based on a standard regulation for the directional roadway, the checking value including at least one of;

a regulated width of the component of the road, or a regulated length of the component of the road;

determine that the motor vehicle is located on the directional roadway of the road having the at least two directional roadways that are structurally separated from each other based on the comparing;

upon determining that the motor vehicle is located on the directional roadway, determine that the motor vehicle is engaged in wrong-way travel based on a directionally dependent property of the at least one visual road feature of the road having the at least two directional roadways that are structurally separated from each other; and

upon determining that the motor vehicle is engaged in wrong-way travel, at least one of;

providing a warning to a driver the motor vehicle, or performing an intervention in the operation of the motor vehicle.

17. The device of claim 16, wherein the at least one visual road feature includes a width of a traffic lane.

18. A device for checking for wrong-way travel of a motor vehicle on a directional roadway of a road, the device comprising:

an image sensor to record at least one visual road feature, the at least one visual road feature including at least one road sign; and

a controller to;

determine, with the aid of the at least on visual road feature, whether the motor vehicle is located on a directional roadway; and

establish the wrong-way travel based on a detection of a back side of the at least one road sign.

19. The device of claim 18, wherein the controller determines whether the motor vehicle is located on the directional roadway based on a detection of a front side of the at least one road sign.
