Abstract

A method for identifying redundantly received information in which the information is contained in vehicle-to-X messages, one vehicle-to-X message comprising at least one item of information, a plurality of vehicle-to-X messages being received by a receiver, and at least one portion of a total number of items of information being received redundantly. The received items of information are entered into an information table and matched with one another before the received information is processed.

Claims

1. A method for identifying redundantly received information items in which the information items are comprised by vehicle-to-X messages, wherein a vehicle-to-X message comprises at least one information item, wherein a receiver receives a multiplicity of vehicle-to-X messages and wherein at least one component of a total number of the information items is received redundantly, and

wherein the received information items are entered into an information table, and are matched against one another, before the received information items are processed.

2. The method as claimed in claim 1,

wherein the redundantly received information items are supplied to the processing in non-redundant form.

3. The method as claimed in claim 1,

wherein the processing is effected by a driver assistance system, wherein the driver assistance system is designed to execute at least one of an autonomous braking intervention, and/or an autonomous steering intervention, and a warning to a driver.

4. The method as claimed in claim 1,

wherein the vehicle-to-X messages are transmitted via different communication paths.

5. The method as claimed in claim 4,

wherein the different communication paths are based on at least one of the following connection types:

WLAN connection, particularly based on IEEE 802.11p,

WiFi Direct,

ISM (Industrial, Scientific, Medical band) connection, particularly using a closing apparatus with radio connection capability,

Bluetooth connection,

ZigBee connection,

UWB (Ultra Wide Band) connection,

WiMax (Worldwide Interoperability for Microwave Access),

Remote Keyless Entry connection,

mobile radio connection, particularly GSM, GPRS, EDGE, UMTS and/or LTE connections, and

infrared connection.

6. The method as claimed in claim 1,

wherein the received vehicle-to-X messages come from a multiplicity of different transmitters.

7. The method as claimed in claim 1,

wherein the redundantly received information items are validated in the information table on the basis of their redundancy, particularly when they come from different transmitters.

8. The method as claimed in claim 1,

wherein only a prescribed number of information items are entered into the information table.

9. The method as claimed in claim 1,

wherein in the case of redundantly received identical information items the information item with the highest information resolution is entered into the information table and is supplied to the processing, wherein already entered identical information items having relatively low information resolution are erased from the information table.

10. The method as claimed in claim 1,

wherein the information items entered into the information table are assigned a holding period, wherein the entered information items are erased after the holding period has elapsed.

11. The method as claimed in claim 10,

wherein the holding period of an information item entered into the information table is determined on the basis of the safety-relevant significance of said information item.

12. The method as claimed in claim 1,

wherein in the case of redundantly received information items the most recent received information item is entered into the information table, wherein an already entered earlier identical information item is erased from the information table.

13. A vehicle-to-X communication system, comprising:

a communication unit for receiving and sending vehicle-to-X messages, an information table module for entering and erasing received information items into and from an information table, and

a matching module for matching information items entered into the information table, wherein

vehicle-to-X communication system executes a method comprising identifying redundantly received information items in which the information items are comprised by vehicle-to-X messages, wherein a vehicle-to-X message comprises at least one information item, wherein a receiver receives a multiplicity of vehicle-to-X messages and wherein at least one component of a total number of the information items is received redundantly,

wherein the received information items are entered into an information table, and are matched against one another, before the received information items are processed.

14. A system as claimed in claim 13,

at least one of the communication unit, the matching Module, and the information table module comprise a common chipset and a common electronic arithmetic and logic unit.

15. The use of the vehicle-to-X communication system for use in a motor vehicle comprising:

a communication unit for receiving and sending vehicle-to-X messages,

an information table module for entering and erasing received information items into and from an information table ,and

a matching module for matching information items entered into the information table.
