Abstract

A method and system for ascertaining at least one traffic-related local information item for a vehicle includes a reception device in a radio system to receive sent data from a radio system in at least one other vehicle in the vicinity of the one vehicle as defined by the reception range of the reception device. The reception device is configured for the vehicle-internal capture and evaluation of data for at least one operating variable from the one vehicle. The traffic-related local information item is ascertained from the received data from the other vehicle.

Claims

1. A method for ascertaining at least one traffic-related local information item for a first vehicle, comprising:

using a reception device of at least one first radio system of the first vehicle to receive data transmitted from a second radio system in at least a second vehicle in a vicinity of the first vehicle defined by the reception range of the reception device, wherein the reception device in the at least first radio system is configured for vehicle-internal capture and evaluation of data for at least first operating variable from the one vehicle; and

ascertaining the at least one traffic-related local information item from the data received from the second radio system.

2. The method as claimed in claim 1, wherein the at least one first radio system is a wireless tire pressure monitoring system.

3. The method as claimed in claim 1, wherein the at least one first radio system is a radio system for receiving data from at least one of a wireless tire pressure monitoring system and a radio key.

4. The method as claimed in claim 1, further comprising forwarding at least one of the data and the traffic-related local information item using at least one further radio system of the first vehicle.

5. The method as claimed in claim 1, wherein the ascertaining of the traffic-related local information item also includes ascertaining at least one movement information item for the vehicle movement of the first vehicle.

6. The method as claimed in claim 1, wherein the traffic-related local information item is at least one of a vehicle density information item, a distance information item relating to the second vehicle, and a relative movement information item for the first and second vehicles.

7. An information system for ascertaining at least one traffic-related local information item for a first vehicle, comprising:

a reception device in a first radio system configured for vehicle-internal capture and evaluation of data for at least one operating variable from the first vehicle, said reception device further configured to receive data transmitted from a second radio system in at least one second vehicle in the vicinity of the first vehicle as defined by the reception range of the reception device; and

an evaluation device for ascertaining the traffic-related local information item from said received data from the second raid system.

8. The system as claimed in claim 7, wherein the first radio system is a wireless tire pressure monitoring system.

9. The system as claimed in claim 7, further comprising at least one further radio system in the first vehicle configured to forward at least one of the data and the traffic-related local information item.

10. The system as claimed in claim 7, wherein the evaluation device also ascertains at least one movement information item for the vehicle movement of the first vehicle.

11. The system as claimed in claim 7, wherein the traffic-related local information item is at least one of a vehicle density information item, a distance information item relating to the second vehicle, and a relative movement information item for the first and second vehicles.
