Abstract

A method for providing an event message indicative of an imminent event for a vehicle. In a first step, a first event message and a second event message are initially received. The first event message represents a signal output by a first mobile terminal device in response to the imminent event; and the second event message represents a signal output by a second mobile terminal device in response to the imminent event. In a further step, an aggregated event message is generated on the basis of the first event message and the second event message. A step follows for ascertaining a plausibility value to check the plausibility of the aggregated event message. Finally, the aggregated event message and the plausibility value are output. The aggregated event message and the plausibility value represent a signal that is receivable from at least one mobile playback device.

First claim

What is claimed is:

1. A method for providing an event message indicative of an imminent event for a vehicle, the method comprising:
receiving event messages indicative of at least one event preceding the imminent event, the event messages indicative of at least one event preceding the imminent event representing signals output by a first plurality of mobile terminals in response to the at least one event preceding the imminent event;
receiving event messages indicative of at least one event subsequent to the imminent event, the event messages indicative of at least one event subsequent to the imminent event representing signals output by a second plurality of mobile terminals in response to the at least one event subsequent to the imminent event;
receiving a first event message, the first event message representing a signal output by a first mobile terminal device of a first vehicle in response to the imminent event;
receiving a second event message, the second event message representing a signal output by a second mobile terminal device of a second vehicle in response to the imminent event;
generating an aggregated event message on the basis of the first event message and the second event message;
combining the received event messages indicative of at least one event preceding the imminent event with the received event messages indicative of at least one event subsequent to the imminent event to determine a maximum possible count of event messages indicative of the imminent event;
ascertaining a plausibility value to check the plausibility of the aggregated event message, the ascertaining including comparing the maximum possible count of event messages to an actual count of event messages indicative of the imminent event, the plausibility value being ascertained based on the result of the comparing; and
outputting the aggregated event message and the plausibility value, the aggregated event message and the plausibility value representing a signal receivable from at least one mobile playback device of the vehicle.

2. The method as recited in claim 1 , wherein a third event message and a fourth event message indicative of one of the at least one event preceding the imminent event are received in a receiving step, the third event message and the fourth event message each representing a signal output by a mobile terminal device in response to the one of the at least one event preceding the imminent event; an aggregated further event message is generated in the generating step on the basis of the third event message and the fourth event message; and in the ascertaining step, the plausibility value also being ascertained on the basis of the aggregated additional event message.

3. The method as recited in claim 2 , wherein:
a fifth event message and a sixth event message indicative of one of the at least one event subsequent to the imminent event are received in the receiving step, the fifth event message and the sixth event message each representing a signal output by a mobile terminal device in response to the one of the at least one event subsequent to the imminent event;
an aggregated additional event message is generated in the generating step on the basis of the fifth event message and the sixth event message; and
in the ascertaining step, the plausibility value also being ascertained on the basis of the aggregated additional event message.

4. The method as recited in claim 3 , wherein:
at least one of the third event message, the fourth event message, the fifth event message, and the sixth event message, are received as a signal output by the first mobile terminal device or the second mobile terminal device;
in a ascertaining step, at least one of a temporal and spatial relation being determined among the imminent event, the one of the at least one event preceding the imminent event and the one of the at least one event subsequent to the imminent event on the basis of at least one of the first event message, the second event message, the third event message, the fourth event message, the fifth event message, and the sixth event message; and
in the ascertaining step, the plausibility value also being ascertained on the basis of the at least one of temporal and spatial relation.

5. The method as recited in claim 1 , wherein in the determining step, an age of the actual number of event messages is additionally considered in order to ascertain the plausibility value.

6. The method as recited in claim 1 , wherein the first mobile terminal device outputs the first event message, and the second mobile terminal device outputs the second event message, and at least one mobile playback device receives the aggregated event message and the plausibility value.

7. The method as recited in claim 1 , wherein further event messages are received in the receiving step, the further event messages representing signals output by other mobile terminal devices of other vehicles in response to the imminent event, and in the generating step, the aggregated event message being generated on the basis of the first event message and the further event messages.

8. A device for providing an event message indicative of an imminent event for a vehicle, the device comprising:
a receiving unit to: (i) receive event messages indicative of at least one event preceding the imminent event, the event messages indicative of at least one event preceding the imminent event representing signals output by a first plurality of mobile terminals in response to the at least one event preceding the imminent event, (ii) receive event messages indicative of at least one event subsequent to the imminent event, the event messages indicative of at least one event subsequent to the imminent event representing signals output by a second plurality of mobile terminals in response to the at least one event subsequent to the imminent event, and (iii) receive a first event message and a second event message, the first event message representing a signal output by a first mobile terminal device of a first vehicle in response to the imminent event, and the second event message representing a signal output by a second mobile terminal device of a second vehicle in response to the imminent event;
a generating unit to generate an aggregated event message on the basis of the first event message and the second event message;
a determining unit to ascertain a plausibility value to check plausibility of the aggregated event message; and
an output unit to output the aggregated event message and the plausibility value, the aggregated event message and the plausibility value representing a signal receivable from at least one mobile playback device of the vehicle;
wherein the device is further configured to combine the received event messages indicative of at least one event preceding the imminent event with the received event messages indicative of at least one event subsequent to the imminent event to determine a maximum possible count of event messages indicative of the imminent event, and wherein the ascertainment of the plausibility value by the determining unit includes comparing the maximum possible count of event messages to an actual count of event messages indicative of the imminent event, the plausibility value being ascertained based on the result of the comparing.

9. A non-transitory machine-readable storage medium storing program code for providing an event message indicative of an imminent event for a vehicle, the program code, when executed by a computer, causing the computer to perform:
receiving event messages indicative of at least one event preceding the imminent event, the event messages indicative of at least one event preceding the imminent event representing signals output by a f
