Abstract

A method for warning about a wrong-way drive situation for a vehicle. The method includes at least reading in a wrong-way drive signal by an interface to a wrong-way drive detection unit. The wrong-way drive signal represents the wrong-way drive situation. The method also includes evaluating the wrong-way drive signal to determine a piece of role information. The piece of role information represents a role of the vehicle with respect to the wrong-way drive situation. The method furthermore includes generating at least one warning signal to warn about the wrong-way drive situation using the piece of role information. The at least one warning signal represents at least one role-dependent warning message. Moreover, the method includes providing the at least one warning signal at an interface to at least one output unit for outputting the at least one warning signal in the vehicle.

First claim

What is claimed is:

1. A method for warning about a wrong-way drive situation for a vehicle, the method comprising:
reading in a wrong-way drive signal by a first interface to a wrong-way drive detection unit, the wrong-way drive signal representing the wrong-way drive situation;
evaluating the wrong-way drive signal to determine a piece of role information, the piece of role information representing a role of the vehicle with respect to the wrong-way drive situation;
generating at least one warning signal to warn about the wrong-way drive situation using the piece of role information, the at least one warning signal representing at least one role-dependent warning message; and
providing the at least one warning signal to a second interface to at least one output unit for outputting the at least one warning signal in the vehicle,
wherein, in the generating, at least one warning signal is generated which represents at least one role-dependent behavior recommendation for occupants of the vehicle, and
wherein, in the providing, the at least one warning signal is provided to output the at least one behavior recommendation after the at least one warning message when an expiration of a predefinable output time duration and/or a reaction of a user in the vehicle to the at least one output warning message is detected.

2. The method of claim 1 , wherein a piece of role information is determined in the evaluating which represents the role of the vehicle as a wrong-way driver, as a road user directly affected by another vehicle driving the wrong way on a shared road or as a road user indirectly affected by another vehicle driving the wrong way on an adjoining road.

3. The method of claim 1 , wherein, in the generating, at least one first warning signal is generated if it was determined in the evaluating that the role of the vehicle is that of a wrong-way driver, at least one second warning signal being generated in the generating if it was determined in the evaluating that the role of the vehicle is that of a road user directly affected by another vehicle driving the wrong way on a shared road, and the at least one second warning signal or at least one third warning signal being generated in the generating if it was determined in the evaluating that the role of the vehicle is that of a road user indirectly affected by another vehicle driving the wrong way on an adjoining road.

4. The method of claim 1 , wherein the at least one output unit includes at least one visual, acoustic and/or haptic output unit, and wherein, in the generating, at least one warning signal is generated which is outputtable visually, acoustically and/or haptically, in the providing, the at least one warning signal being provided to the second interface to the at least one visual, acoustic and/or haptic output unit.

5. The method of claim 1 , wherein, in the providing, the at least one warning signal is provided until an expiration of a predefinable output time duration and/or a reaction of a user in the vehicle to the at least one output warning signal is detected.

6. The method of claim 1 , wherein, in the providing, the at least one warning signal is provided until an implementation of the at least one behavior recommendation is detected using drive data of the vehicle.

7. The method of claim 1 , wherein, in the providing, the at least one warning signal is provided until a cancellation signal is received, the cancellation signal representing a cancellation of the wrong-way drive situation.

8. The method of claim 1 , wherein, in the reading in, a wrong-way drive signal is read in which, with respect to the wrong-way drive situation, includes at least one piece of position information, one piece of direction information and/or one piece of time information.

9. A device for warning about a wrong-way drive situation for a vehicle, comprising:
a warning device configured to perform the following:
reading in a wrong-way drive signal by a first interface to a wrong-way drive detection unit, the wrong-way drive signal representing the wrong-way drive situation;
evaluating the wrong-way drive signal to determine a piece of role information, the piece of role information representing a role of the vehicle with respect to the wrong-way drive situation;
generating at least one warning signal to warn about the wrong-way drive situation using the piece of role information, the at least one warning signal representing at least one role-dependent warning message; and
providing the at least one warning signal to a second interface to at least one output unit for outputting the at least one warning signal in the vehicle,
wherein, in the generating, at least one warning signal is generated which represents at least one role-dependent behavior recommendation for occupants of the vehicle, and
wherein, in the providing, the at least one warning signal is provided to output the at least one behavior recommendation after the at least one warning message when an expiration of a predefinable output time duration and/or a reaction of a user in the vehicle to the at least one output warning message is detected.

10. A system for warning about a wrong-way drive situation for a vehicle, comprising:
a device configured to perform the following:
reading in a wrong-way drive signal by a first interface to a wrong-way drive detection unit, the wrong-way drive signal representing the wrong-way drive situation;
evaluating the wrong-way drive signal to determine a piece of role information, the piece of role information representing a role of the vehicle with respect to the wrong-way drive situation;
generating at least one warning signal to warn about the wrong-way drive situation using the piece of role information, the at least one warning signal representing at least one role-dependent warning message; and
providing the at least one warning signal to a second interface to at least one output unit for outputting the at least one warning signal in the vehicle,
wherein, in the generating, at least one warning signal is generated which represents at least one role-dependent behavior recommendation for occupants of the vehicle, and
wherein, in the providing, the at least one warning signal is provided to output the at least one behavior recommendation after the at least one warning message when an expiration of a predefinable output time duration and/or a reaction of a user in the vehicle to the at least one output warning message is detected; and

at least one output unit for outputting the at least one warning signal in the vehicle, the at least one output unit and the device being connected to one another in a signal transmission-capable manner.

11. The system of claim 10 , wherein the device and/or the at least one output unit is part of a mobile device situatable or situated in the vehicle or fixedly installed in the vehicle.

12. A non-transitory computer readable medium having a computer program, which is executable by a processor, comprising:
a program code arrangement having program code for warning about a wrong-way drive situation for a vehicle, by performing the following:
reading in a wrong-way drive signal by a first interface to a wrong-way drive detection unit, the wrong-way drive signal representing the wrong-way drive situation;
evaluating the wrong-way drive signal to determine a piece of role information, the piece of role information representing a role of the vehicle with respect to the wrong-way drive situation;
generating at least one warning signal to warn about the wrong-way drive situation using the piece of role information, the at least one warning signal representing at least one role-dependent warning me
