Abstract

A method for providing information about traffic regulations in a vehicle is disclosed. The method comprises identifying a road sign in a surrounding area of the vehicle (e.g. by means of a perception system of the vehicle). Further, the method comprises identifying a traffic regulation associated with the identified road sign, in a current jurisdiction of vehicle, and retrieving traffic regulation data comprising information about a set of predefined road signs and associated predefined traffic regulations in a predefined jurisdiction. Still further, the method comprises comparing the identified traffic regulation with the retrieved traffic regulation data in order to determine if the identified road sign is not comprised in the set of predefine road signs, or if the identified traffic regulation differs from the associated predefined traffic regulations.

Claims (43)

1. A method for providing information about traffic regulations in a vehicle, the method comprising:

identifying a road sign in a surrounding area of the vehicle;

identifying a traffic regulation associated with the identified road sign, in a current jurisdiction determined by a current geographical position of the vehicle;

receiving traffic regulation data comprising information about a set of predefined road signs and associated predefined traffic regulations in a predefined jurisdiction;

comparing the identified traffic regulation with the received traffic regulation data in order to determine if the identified road sign is comprised in the set of predefined road signs, or if the identified traffic regulation differs from the associated predefined traffic regulations; and

if it is determined that the identified road sign is not comprised in the set of predefined road signs or that the identified traffic regulation differs from the predefined traffic regulations, generating an output comprising information about the identified traffic regulation for the identified road sign to a driver of the vehicle.

2. The method according to claim 1 , further comprising:

determining the current geographical position of the vehicle by means of a Global Navigation Satellite System, (GNSS),

wherein the step of identifying a traffic regulation associated with the identified road sign is only performed if the current geographical position is outside of a geographical area defined by the predefined jurisdiction.

3. The method according to claim 1 , wherein the step of identifying a road sign in a surrounding area of the vehicle comprises identifying a road sign in a surrounding area of the vehicle by means of an image sensor.

4. The method according to claim 1 , wherein the step of identifying a road sign in a surrounding area of the vehicle comprises identifying a road sign in a surrounding area of the vehicle by means of a map data.

5. The method according to claim 1 , wherein the step of identifying a road sign in a surrounding area of the vehicle comprises identifying a road sign in a surrounding area of the vehicle by means of traffic sign telemetry data.

6. The method according to claim 1 , wherein the step of generating the output comprising information about the associated traffic regulation for the identified road sign to the driver of the vehicle comprises generating an output comprising information about a significance for a violation of the associated traffic regulation.

7. The method according to claim 6 , further comprising:

receiving vehicle data from a control unit of the vehicle; and

wherein the information about a significance for a violation of the associated traffic regulation is based on the vehicle data.

8. The method according to claim 7 , wherein the vehicle data comprises at least one of a velocity of the vehicle, number of passengers in the vehicle, weight of the vehicle, height of the vehicle, length of the vehicle, width of the vehicle, a geographical position of the vehicle, and a steering input.

9. The method according to claim 1 , wherein the step of generating an output comprising information about the associated traffic regulation for the identified road sign to the driver of the vehicle comprises generating a visual feedback comprising information about the associated traffic regulation for the identified road sign to the driver of the vehicle.

10. The method according to claim 1 , wherein the step of generating an output comprising information about the associated traffic regulation for the identified road sign to the driver of the vehicle comprises generating an audio feedback comprising information about the associated traffic regulation for the identified road sign to the driver of the vehicle.

11. The method according to claim 1 , wherein the step of generating an output comprising information about the associated traffic regulation for the identified road sign to the driver of the vehicle comprises generating a tactile feedback.

12. A non-transitory computer-readable storage medium storing one or more programs configured to be executed by one or more processors of a vehicle control system, the one or more programs comprising instructions for performing the method according to claim 1 .

13. A control device comprising:

at least one processor;

at least one memory;

at least one sensor interface;

at least one communication interface;

wherein the processor is configured to execute instructions stored in the memory to perform a method for providing information about traffic regulations in a vehicle, wherein the method comprises:

receiving sensor data, via the at least one sensor interface, in order to identify a road sign in a surrounding area of the vehicle;

identifying a traffic regulation associated with the identified road sign, in a current jurisdiction determined by a current geographical position of the vehicle;

receiving, via the at least one communication interface, traffic regulation data comprising information about a set of predefined road signs and associated predefined traffic regulations in a predefined jurisdiction;

comparing the identified traffic regulation with the received traffic regulation data in order to determine if the identified road sign is not comprised in the set of predefine road signs, or if the identified traffic regulation differs from the associated predefined traffic regulations; and

if it is determined that the identified road sign is not comprised in the set of predefined road signs or that the identified traffic regulation differs from the predefined traffic regulations, generating an output comprising information about the identified traffic regulation for the identified road sign to a driver of the vehicle.

14. A vehicle comprising a control device comprising:

at least one processor;

at least one memory;

at least one sensor interface;

at least one communication interface;

wherein the processor is configured to execute instructions stored in the memory to perform a method for providing information about traffic regulations in a vehicle, wherein the method comprises:

receiving sensor data, via the at least one sensor interface, in order to identify a road sign in a surrounding area of the vehicle;

identifying a traffic regulation associated with the identified road sign, in a current jurisdiction determined by a current geographical position of the vehicle;

receiving, via the at least one communication interface, traffic regulation data comprising information about a set of predefined road signs and associated predefined traffic regulations in a predefined jurisdiction;

comparing the identified traffic regulation with the received traffic regulation data in order to determine if the identified road sign is not comprised in the set of predefine road signs, or if the identified traffic regulation differs from the associated predefined traffic regulations; and

if it is determined that the identified road sign is not comprised in the set of predefined road signs or that the identified traffic regulation differs from the predefined traffic regulations, generating an output comprising information about the identified traffic regulation for the identified road sign to a driver of the vehicle.
