Abstract

In a method for detecting traffic and/or accident data at a road junction by means of a vehicle which has a control unit which is coupled to at least one sensor of the vehicle, in a first step, the sensor detects traffic crossing the vehicle; and in a second step, the data which represents the crossing traffic is transmitted from the control unit of the vehicle to at least one receiver external to the vehicle. The method for detecting traffic and accident data at road junctions represents a significant improvement for avoiding accidents and/or traffic congestions.

Claims

1-8. -8. (canceled)

9. A method for capturing at least one of traffic data and accident data at a junction in road traffic by using a vehicle having a control unit which is coupled to at least one sensor of the vehicle, the method comprising:

capturing with the sensor crossing traffic moving across the vehicle; and

transmitting with the control unit of the vehicle data representing the crossing traffic to at least one receiver external to the vehicle, wherein the external receiver comprises a central data processing facility; and

statistically analyzing the transmitted data in the data processing facility so as to form a history of a traffic flow at the junction.

10. The method of claim 9, further comprising, before transmitting the data, pre-processing the data representing the crossing traffic with the control unit of the vehicle.

11. The method of claim 10, wherein the pre-processed data represent at least one of a time, a duration, location coordinates and a number of road users crossing the vehicle.

12. The method of claim 10, wherein the pre-processed data comprise information about a state of activation of a driver assistance system of the vehicle.

13. The method according to claim 12, wherein the data evaluated by the receiver form a basis for navigation planning and route planning.

14. A device for capturing at least one of traffic data and accident data at a junction in road traffic by using a vehicle, wherein the vehicle comprises

at least one sensor coupled with the control unit and configured to detect traffic crossing the vehicle, and

a control unit configured to transmit data of traffic crossing the vehicle from the control unit to at least one receiver external to the vehicle for processing, wherein the external receiver comprises a central data processing facility, with the data processing facility being configured to statistically evaluate the transmitted data to form a history of a traffic volume at the junction.

15. The device of claim 14, wherein the external receiver comprises a control unit of another vehicle.

16. The device of claim 15, wherein the at least one sensor (ST) is a photographic sensor and/or an infrared sensor and/or a radar sensor and/or a laser sensor and/or an acoustic sensor.
