Abstract

In a method for associating a transmitter which transmits at least one communication information in a car-to-car communication with an object in a receiving motor vehicle wherein the object is described by environmental data from at least one environmental sensor, wherein the association occurs based on comparing environmental data from at least one environmental sensor of the motor vehicle having the transmitter with corresponding environmental data of the receiving motor vehicle.

Claims

1. A method for associating an object in car-to-car communication, comprising:

transmitting with a transmitter located in a host motor vehicle in the car-to-car communication at least one communication information to a receiving motor vehicle; and

associating in a controller the at least one communication information with an object being described by environmental data from at least one environmental sensor in the receiving motor vehicle by comparing environmental data contained in the at least one communication information from the at least one environmental sensor of the host motor vehicle with corresponding environmental data of the receiving motor vehicle.

2. The method of claim 1, wherein the environmental data are compared by analyzing a list of all objects detected in a vicinity of the host motor vehicle.

3. The method of claim 1, further comprising comparing a relative position contained in the environmental data in relation to the host motor vehicle and a relative position contained in the environmental data of the receiving motor vehicle in relation to the receiving motor vehicle, and identifying mutually detected motor vehicles from the environmental data of a respective other motor vehicle.

4. The method of claim 3, further comprising ascertaining a match when the respective relative positions have matching opposing distance vectors.

5. The method of claim 3, further comprising comparing relative speeds, wherein a match of the relative speeds is ascertained when the relative speed of an object relative to the host motor vehicle corresponds to a negative value of the relative speed of an object relative to the receiving motor vehicle.

6. The method of claim 1, further comprising associating, based on the comparison result, at least one item of information relating to the host vehicle contained in the communication information with the host motor vehicle detected with the at least one environmental sensor by the receiving motor vehicle.

7. The method of claim 1, further comprising, in context of a plausibility check, checking the association by evaluating GPS information contained in the communication information of the host motor vehicle.

8. A motor vehicle, comprising:

a receiving device configured to receive communication information transmitted by a transmitter located in a host motor vehicle, at least one environmental sensor; and

a controller configured to transmit with the transmitter in a car-to-car communication at least one communication information to a receiving motor vehicle, and to associate the at least one communication information with an object being described by environmental data from the at least one environmental sensor in the receiving motor vehicle by comparing environmental data contained in the at least one communication information from the at least one environmental sensor of the host motor vehicle with corresponding environmental data of the receiving motor vehicle.
