Method for communication within an, in particular wireless, motor vehicle communication system interacting in an ad-hoc manner, device for the traffic infrastructure and road user device
First Claim
1. A method for communication based on a motor vehicle communication system interacting in an ad-hoc manner, wherein the communication is carried out between road users among each other, between road users and a traffic infrastructure, or a combination thereof, the method comprising:
- continuously transmitting, by a first radio transmission/radio reception device associated with a first road user, in a near field of an intersection of traffic routes a first message to at least one radio transmission/radio reception device associated with a device of the traffic infrastructure, located in a radio coverage area of the first radio transmission/radio reception device, the transmission of the first message being carried out such that, based on the received first message, at least one value correlating with a probability for execution of a maneuver at the intersection is ascertained per possible maneuver at the intersection, the first message including an estimated period of time before completing each possible maneuver; and
controlling the first road user based on the at least one correlating value.

Abstract
The invention relates to a method for communication on the basis of an, in particular wireless, motor vehicle communication system interacting in an ad-hoc manner, wherein the communication takes place between road users themselves and/or between road users and traffic infrastructure, in which, in the vicinity of a node for traffic routes, particularly junctions or intersections between traffic routes such as road or rail junctions, a radio transmission/radio reception device associated with a first road user continuously sends a message to at least one second radio transmission/radio reception device, which is situated in the radio coverage area of the first radio transmission/radio reception device and is associated with a device for the traffic infrastructure, the message is sent such that, on the basis of the received message, for each manoeuvre that is possible at the node, at least one value correlating to a probability of execution of the manoeuvre at the node is ascertained, and the road users are controlled on the basis of the correlating value. The invention also relates to a device for the traffic infrastructure and to a road user device having means for carrying out the method.

23. A device of a traffic infrastructure for communication based on a motor vehicle communication system interacting in an ad-hoc manner, wherein the communication is carried out between road users among each other, between road users and the traffic infrastructure, or a combination thereof, the device comprising:
-
a radio transmission/radio reception device operable to receive at least a first message transmitted by another radio transmission/radio reception device associated with a first road user, wherein the radio transmission/radio reception device is configured to; ascertain, per possible maneuver at intersection, at least one value correlating with a probability for execution of the maneuver at the intersection based on the received first message, the first message including an estimated period of time before completing each possible maneuver; control the first road user based on the correlating value; form a second message; and transmit the second message to the other radio transmission/radio reception device.

24. A road user device for communication based on a motor vehicle communication system interacting in an ad-hoc manner, wherein the communication is carried out between road users among each other, between road users and traffic infrastructure, or a combination thereof, the road user device comprising:
-
a first radio transmission/radio reception device configured to; transmit at least a first message to a second radio transmission/radio reception device, the second radio transmission/radio reception device being associated with a device of the traffic infrastructure that is located in a radio coverage area of the first radio transmission/radio reception device, the transmission of the first message being carried out such that, based on the received first message at the second radio transmission/radio reception device, a first direction of a change in position of the road user is ascertained, the first message including an estimated period of time before completing each possible maneuver; receive a second message transmitted in the case of a control; and carry out a procedure related to the control.
