Abstract

A method for warning a motor vehicle of a collision with a rail vehicle, in which, using an electronic computing device arranged externally of the vehicle, first movement data of the rail vehicle, which characterize a position and/or a speed of the rail vehicle, are received from a sensor device permanently installed in a rail network and/or are determined as a function of an electronic timetable. A hazardous situation is determined as a function of the first movement data and position data of at least one level crossing, which position data characterize a position of the level crossing. A hazard information signal, which can be called up by the motor vehicle and characterizes the hazardous situation, is provided for the motor vehicle as a function of the hazardous situation.

First claim

1 - 6 . (canceled)

7 . A method for warning a motor vehicle of a collision with a rail vehicle, the method comprising:
receiving, by a first electronic computing device arranged externally of the vehicle from a sensor device permanently installed in a rail network, first movement data of the rail vehicle or determining, by the first electronic computing device, the first movement data as a function of an electronic timetable, wherein the first movement data characterizes a position or a speed of the rail vehicle; determining, by the first electronic computing device, a hazardous situation as a function of the first movement data and position data of at least one level crossing, wherein the position data characterize a position of the level crossing; receiving, by the first electronic computing device from a second electronic computing device of the motor vehicle arranged in the vehicle, second movement data of the motor vehicle, wherein the second movement data characterize a position or a speed of the motor vehicle; providing, by the first electronic computing device to the second electronic computing device, a hazard information signal as a function of the hazardous situation, wherein the hazard information signal characterizes the hazardous situation, determining, by the second computing device as a function of the second movement data, a maximum distance of the motor vehicle from the position of the level crossing; and outputting, in the motor vehicle, a warning message responsive to the maximum distance being undershot by the motor vehicle.

8 . The method of claim 7 , wherein when second electronic computing device receives the hazard information signal, the warning message is output in the motor vehicle as a function of a characteristic of the level crossing.

9 . The method of claim 7 , movement and the position of the rail vehicle in the rail network comprising the level crossing is determined for the rail vehicle by the first electronic computing device as a function of the first movement data.

10 . The method of claim 7 , movement and the position of the motor vehicle in a road network comprising the level crossing is determined for the motor vehicle by the first electronic computing device as a function of the second movement data.

11 . The method of claim 10 , further comprising:
determining, as a function of the road network, the second movement data, and the position data, a crossing probability, wherein the crossing probability characterizes a probability of a crossing event of the level crossing by the motor vehicle, wherein, upon receipt of the hazard information signal, the warning message is output in the motor vehicle as a function of the crossing probability.

12 . A system for warning a motor vehicle of a collision with a rail vehicle, the system comprising:
a first electronic computing device arranged externally of the vehicle; a second electronic computing device of the motor vehicle arranged in the vehicle; and an output of the motor vehicle arranged in the motor vehicle, wherein the first electronic computing device is configured to
receive, from a sensor device permanently installed in a rail network, first movement data of the rail vehicle or determine the first movement data as a function of an electronic timetable, wherein the first movement data characterizes a position or a speed of the rail vehicle;
determine a hazardous situation as a function of the first movement data and position data of at least one level crossing, wherein the position data characterize a position of the level crossing;
provide, to the second electronic computing device, a hazard information signal as a function of the hazardous situation, wherein the hazard information signal characterizes the hazardous situation,
wherein the second electronic computing device is configured to determine, as a function of the second movement data, a maximum distance of the motor vehicle from the position of the level crossing, and wherein the second electronic computing device is configured to control the output to output a warning message responsive to the maximum distance being undershot by the motor vehicle.
