System and method for the dynamic and robust updating of a digital map
View Patent ↗A system and a method for the dynamic and robust updating of a digital map for self-driving vehicles are provided. The system includes a server that is configured to determine a non-up-to-date geographical region of the digital map. The system also includes a vehicle fleet having a plurality of self-driving vehicles. The server is configured to determine the geographical position of the vehicles, to select a suitable vehicle from the vehicle fleet, and to instruct the selected vehicle to move to the non-up-to-date region of the digital map. The vehicle is configured to capture, in the non-up-to-date geographical region, data that is suitable for updating the non-up-to-date geographical region of the digital map.
1. A system for updating a digital map for automated driving vehicles, the system comprising:
a server configured to determine a non-up-to-date geographical region of the digital map; and
a vehicle fleet comprising a plurality of automated driving vehicles,
wherein the server is configured to:
determine geographical positions of the vehicles;
select a suitable vehicle of the vehicle fleet;
instruct the selected vehicle to move to the non-up-to-date geographical region of the digital map; and
capture, at the non-up-to-date geographical region, data suitable for updating the non-up-to-date geographical region of the digital map.
2. The system according to claim 1 ,
wherein the digital map comprises a mobile radio network coverage map; and
wherein the server is configured to determine the non-up-to-date geographical region of the digital map by determining a non-up-to-date region of a mobile radio network coverage map.
3. The system according to claim 1 , wherein the server is configured to capture the data in the non-up-to-date geographical region by at least one of:
carrying out a data rate measuring method in an uplink;
carrying out a data rate measuring method in a downlink;
carrying out a latency measurement; or
measuring relevant network parameters of a mobile radio network at a measurement time.
4. The system according to claim 1 , wherein the server is configured to determine the non-up-to-date geographical region of the digital map with aid of a suitable algorithm.
5. A method for updating a digital map for automated driving vehicles, the method comprising:
determining, by a server, a non-up-to-date geographical region of the digital map;
determining, by the server, a geographical position of a plurality of automated driving vehicles of a vehicle fleet;
selecting, by the server, a suitable vehicle of the vehicle fleet;
instructing, by the server, the selected vehicle to move to the non-up-to-date geographical region of the digital map; and
capturing, by the selected vehicle, data suitable for updating the non-up-to-date geographical region of the digital map.
6. The method according to claim 5 ,
wherein the digital map comprises a mobile radio network coverage map; and
wherein determining the non-up-to-date geographical region comprises determining a non-up-to-date region of the mobile radio network coverage map.
7. The method according to claim 5 , wherein capturing the data in the non-up-to-date geographical region comprises at least one of:
carrying out a data rate measuring method in an uplink;
carrying out a data rate measuring method in a downlink;
carrying out a latency measurement; or
measuring relevant network parameters of a mobile radio network at a measurement time.
8. The method according to claim 5 , wherein determining the non-up-to-date geographical region of the digital map is effected with aid of a suitable algorithm.
