First Claim
Patent Images
1. A method for communicating based on an ad hoc-type motor vehicle communication system, the method comprising:
- receiving, by a radio transceiver device of a transportation infrastructure device, a first set of messages from a plurality of motor vehicles;
determining, by the transportation infrastructure device, a directional traffic flow history of a road based on the received first set of messages;
receiving, by the radio transceiver device, a second set of messages from a motor vehicle;
determining, by the transportation infrastructure device, a direction of a position change of the motor vehicle based on the received second set of messages;
determining, by the transportation infrastructure device, a correlation between the direction of the position change and the directional traffic flow history;
determining, by the transportation infrastructure device, a presence of a hazardous situation, wherein the presence of a hazardous situation occurs when there is a lack of correlation indicating travel in a wrong direction; and
transmitting, by the radio transceiver device, a hazard message to the motor vehicle indicating the presence of the hazardous situation.

Abstract
A method for communicating based on an ad hoc-type motor vehicle communication system, in which transportation users communicate with one another and/or transportation users and the transportation infrastructure communicate, includes determining the valid directions of travel independently based on messages transmitted by transportation users and determining travel in the wrong direction based on these messages. Corresponding further messages may be transmitted in response to the hazardous situation. A transportation infrastructure device and to a transportation user device may implement the method.

17. A transportation infrastructure device for communicating based on an ad hoc-type motor vehicle communication system, the transportation infrastructure device comprising:
-
a radio transceiver device configured to; receive a first set of messages from a plurality of motor vehicles; receive a second set of messages from a motor vehicle; and transmit a hazard message to the motor vehicle based on a presence of a hazardous situation on a road, wherein the transportation infrastructure device is configured to; determine a directional traffic flow history of the road based on the first set of messages received from the plurality of motor vehicles; determine a direction of a position change of the motor vehicle based on the received second set of messages; determine a correlation between the direction of the position change of the motor vehicle and the directional traffic flow history; and determine the presence of the hazardous situation indicating travel on the road in a wrong direction when there is a lack of correlation.

18. A transportation user device of a transportation user for communicating based on ad hoc-type motor vehicle communication system, via which transportation users communicate with one another, the transportation users communicate with a transportation infrastructure, or the transportation users communicate with one another and the transportation infrastructure, the transportation user device comprising:
-
a first radio transceiver device associated with the transportation user device configured to transmit a plurality of messages to a transportation infrastructure device or another transportation user in a radio supply area of the radio transceiver device and receive a hazard message when a direction of a position change of the transportation user is not correlated with a traffic flow direction of a location of the transportation user, wherein each message of the plurality of messages includes a position the transportation user on at least one road; wherein the transportation user device implements an automated procedure based on the receipt of the hazardous situation when a degree of correlation value of the direction of the position change and the traffic flow direction is substantially zero, revealing a hazardous situation.
