Abstract: Technologies and techniques for reducing a collision risk between a first motor vehicle and a second motor vehicle. At least a first vehicle-to-environment message is transmitted by the first motor vehicle and received by the second motor vehicle. Using a second computing unit of the second motor vehicle, it is determined, depending on the vehicle-to-environment message, whether a risk situation exists in which the first motor vehicle is obscured by a preceding third motor vehicle. The second computing unit executes a criticality analysis to determine that the risk situation exists and, depending on the result of the criticality analysis, a risk-reducing measure is initiated.

Abstract: Methods, devices, and computer programs for a transportation vehicle including receiving information about a triggering of one or more functions of the transportation vehicle, determining a dangerous situation based on the one or more triggered functions of the transportation vehicle based on an actual activity of the driver of the transportation vehicle, and providing information about the dangerous situation to a vehicle-to-vehicle interface.

Abstract: Devices, methods and computer programs for making available information about an end of a traffic jam via a vehicle-to-vehicle interface. The device for a transportation vehicle includes an apparatus to receive indicators about an end of a traffic jam. The indicators include at least one element of the group of kinetic information of the transportation vehicle or of transportation vehicles in an area surrounding the transportation vehicle and traffic jam warnings. The device also includes an apparatus to determine information about an end of a traffic jam based on the indicators. The information about the end of a traffic jam indicates that the transportation vehicle will reach the end of a traffic jam in the near future. The device also includes a vehicle-to-vehicle interface to make available information about the end of a traffic jam to one or more other transportation vehicles via a vehicle-to-vehicle communication link.

Abstract: Devices, methods, and computer programs for providing traffic jam information via a vehicle-to-vehicle interface. The device for a transportation vehicle includes a device for obtaining traffic jam indicators. The traffic jam indicators include at least one element of the group consisting of the speed of the transportation vehicle or of transportation vehicles in an area surrounding the transportation vehicle and a traffic jam warning. The device also includes a device for determining traffic jam information based on the traffic jam indicators. The traffic jam information indicates whether the transportation vehicle is located in a traffic jam. The device also includes a vehicle-to-vehicle interface to provide the traffic jam information to one or more additional transportation vehicles via a vehicle-to-vehicle communication connection.

Abstract: A method for the communication of vehicles including receiving a first message from a first vehicle by a second vehicle via vehicle-to-vehicle communication and/or vehicle-to-infrastructure communication and allocating the first message to the first vehicle based on the content of the first message by the second vehicle The method includes sending a second message from the second vehicle to the first vehicle via a separate communication channel by using information from the first message. Also disclosed is a method for vehicles to exchange data unrelated to traffic with one another.
