Abstract

The invention relates to a method for determining traffic information with the aid of a central monitoring device which is in communication with a plurality of fleet vehicles in order to obtain traffic information from the fleet vehicles, wherein within communication with the fleet vehicles the monitoring device transmits targeted measurement requests to the fleet vehicles. In one exemplary aspect, the invention proposes that during the transmission of targeted measurement requests, the monitoring device takes account of the quality of sensors with which the individual fleet vehicle are equipped.

First claim

What is claimed is:

1. A method for determining traffic information, using a central monitoring device which is in communication with a plurality of fleet vehicles in order to receive traffic information from the fleet vehicles, the monitoring device being remote to the plurality of fleet vehicles, comprising:
transmitting, within the communication with the fleet vehicles, by the monitoring device targeted measurement requests to the fleet vehicles, which targeted measurement requests comprise georeferenced data that refers to map elements to be updated;
wherein within the transmission of targeted measurement requests the monitoring device takes into account the quality of sensors with which the individual fleet vehicles are equipped; and
requesting, by the monitoring device, the traffic information from the fleet vehicles, which locally can process the sensor data into traffic information.

2. The method of claim 1 ,
wherein within transmitting targeted measurement requests the monitoring device takes into account the quality of map sections,
wherein the quality of the map sections comprises one or more of the age, the accuracy, and the uncertainty of the map sections.

3. The method of claim 1 , wherein the quality of the sensors includes at least one information of the group of information of:
a) type of sensors,
b) position of the sensors on the fleet vehicle,
c) alignment of the sensors,
d) resolution of the sensors,
e) calibration of the sensors,
f) software support, hardware support, connectivity of the sensors on the fleet vehicle, and
g) suitability of the sensors to detect certain measurement requests from the monitoring device.

4. The method of claim 1 , wherein within transmitting targeted measurement requests the monitoring device takes into account sensor groups and / or sensor combinations with which the individual fleet vehicles are equipped.

5. The method of claim 1 , wherein the monitoring device periodically updates the measurement requests and / or takes into account inquiries from the fleet vehicles within creating the measurement requests.

6. The method of claim 1 , wherein the communication between the monitoring device and the fleet vehicles is carried out via one or more of a mobile communication connection, sound waves, radio waves, electromagnetic waves, and the Internet.

7. A system for determining traffic information, with a central monitoring device which is in communication with a plurality of fleet vehicles in order to receive traffic information from the fleet vehicles,
wherein within communicating with the fleet vehicles the monitoring device transmits targeted measurement requests to the fleet vehicles, which targeted measurement requests comprise georeferenced data that refers to map elements to be updated,
wherein the monitoring device is designed to carry out the method according to claim 1 .

8. The system of claim 7 , wherein the monitoring device comprises a memory device in which one or more of the traffic information, measurement requests, map sections, information about the quality of different map sections, and information about the quality of different sensors are stored.

9. The system of claim 7 , wherein the monitoring device comprises a control device which is configured for one or more of creating to create targeted measurement requests to the fleet vehicles, and evaluating the quality of sensors with which the individual fleet vehicles are equipped.

10. The method of claim 2 , wherein the quality of the sensors includes at least one information of the group of information of:
a) type of sensors,
b) position of the sensors on the fleet vehicle,
c) alignment of the sensors,
d) resolution of the sensors,
e) calibration of the sensors,
f) software support, hardware support, connectivity of the sensors on the fleet vehicle, and
g) suitability of the sensors to detect certain measurement requests from the monitoring device.

11. The method of claim 2 , wherein within transmitting targeted measurement requests the monitoring device takes into account sensor groups and / or sensor combinations with which the individual fleet vehicles are equipped.

12. The method of claim 3 , wherein within transmitting targeted measurement requests the monitoring device takes into account sensor groups and / or sensor combinations with which the individual fleet vehicles are equipped.

13. The method of claim 2 , wherein the communication between the monitoring device and the fleet vehicles is carried out via one or more of a mobile communication connection, sound waves, radio waves, electromagnetic waves, and the Internet.

14. The method of claim 3 , wherein the communication between the monitoring device and the fleet vehicles is carried out via one or more of a mobile communication connection, sound waves, radio waves, electromagnetic waves, and the Internet.

15. The method of claim 4 , wherein the communication between the monitoring device and the fleet vehicles is carried out via one or more of a mobile communication connection, sound waves, radio waves, electromagnetic waves, and the Internet.

16. The method of claim 5 , wherein the communication between the monitoring device and the fleet vehicles is carried out via one or more of a mobile communication connection, sound waves, radio waves, electromagnetic waves, and the Internet.

17. The system of claim 8 , wherein the monitoring device comprises a control device which is configured for one or more of creating targeted measurement requests to the fleet vehicles, and evaluating the quality of sensors with which the individual fleet vehicles are equipped.

18. The system of claim 7 , wherein the monitoring device comprises a control device which is configured for one or more of evaluating the quality of map sections that are stored in the storage device, and processing traffic information.

19. The system of claim 8 , wherein the monitoring device comprises a control device which is configured for one or more of evaluating the quality of map sections that are stored in the storage device, and processing traffic information.
