Abstract

A method is described for ascertaining particular pieces of status information for at least one geographical position with the aid of autonomous or semi-autonomous vehicles,at least one autonomous or semi-autonomous vehicle detecting pieces of information from its surroundings during a drive with using at least one surroundings sensor and carrying out a planning of its instantaneous travel trajectory based on the obtained pieces of information, and the vehicle detecting additional pieces of information from its surroundings with using its surroundings sensor during a stop, which are not used for planning its instantaneous travel trajectory. The vehicle conveys the ascertained additional pieces of information, with a geographical position at which the additional pieces of information have been detected, to an external server. The external server uses the data received from the vehicle to ascertain at least one piece of status information for the respective geographical position.

First claim

What is claimed is:

1. A method for ascertaining particular pieces of status information for at least one geographical position with the aid of autonomous or semi-autonomous vehicles, the method comprising:
detecting, by at least one autonomous or semi-autonomous vehicle, pieces of information from its surroundings during a drive using at least one surroundings sensor;
carrying out, by the at least one autonomous or semi-autonomous vehicle, a planning of an instantaneous travel trajectory of the at least one autonomous or semi-autonomous vehicle based on the detected pieces of information;
detecting, by the at least one autonomous or semi-autonomous vehicle, additional pieces of information from the surroundings using the at least one surroundings sensor, during a stop caused by: (1) an instantaneous traffic situation, or (11) a traffic sign, or (iii) another piece of traffic infrastructure, the detected additional pieces of information not being used by the at least one autonomous or semi-autonomous vehicle for planning its instantaneous travel trajectory;
conveying, by the at least one autonomous or semi-autonomous vehicle, the detected additional pieces of information, together with a respective geographical position at which the detected additional pieces of information have been detected, in a form of data to an external server; and
using, by the external server, the data received from the at least one autonomous or semi-autonomous vehicle, to ascertain at least one piece of status information for the respective geographical position.

2. The method as recited in claim 1 , wherein the at least one autonomous or semi-autonomous vehicle identifies vehicles and/or passers-by and/or other objects and/or weather conditions in its surroundings during the stop using the at least one surroundings sensor, and ascertains as the additional pieces of information, and/or a status, and/or a number, and/or an arrangement and/or a movement status of the autonomous or semi-autonomous vehicles and/or the passers-by and/or the other objects and/or the weather conditions, identified by the at least one autonomous or semi-autonomous vehicle.

3. The method as recited in claim 1 , wherein, during the stop, the at least one autonomous or semi-autonomous vehicle ascertains, as the additional piece of information, instantaneous weather conditions at its whereabouts using the at least one surroundings sensor.

4. The method as recited in claim 1 , wherein the external server uses the additional pieces of information received from the at least one autonomous or semi-autonomous vehicle to determine at least one of the following pieces of status information for the respective geographical position:
traffic density of vehicles and/or traffic density of passers-by;
local weather conditions and/or regional weather conditions;
extent and progress of construction sites;
status of roads, buildings, and other structures;
status of traffic infrastructures;
degree of occupancy of existing parking areas;
efficiency of traffic routing and/or traffic control;
need for maintenance operations of the roads and/or need for cleaning operations of the roads and/or of other traffic infrastructures;
status of vegetation.

5. The method as recited in claim 1 , wherein the external server sends a request relating to particular additional pieces of information to the at least one autonomous or semi-autonomous vehicle to request the at least one autonomous or semi-autonomous vehicle to convey to the server the particular additional pieces of information from at least one geographical position, and the at least one autonomous or semi-autonomous vehicle ascertains the requested particular additional pieces of information and sends the requested particular additional pieces of information to the external server as a response to the request.

6. The method as recited in claim 1 , wherein the at least one autonomous or semi-autonomous vehicle ascertains its geographical position using a satellite-assisted navigation unit and/or using a feature map, and sends the ascertained geographical position in a form of data to the external server.

7. The method as recited in claim 1 , wherein the external server receives corresponding additional pieces of information and associated geographical positions from multiple vehicles and uses the received corresponding additional pieces of information and the received associated geographical positions for ascertaining at least one piece of status information for at least one geographical position.

8. The method as recited in claim 1 , wherein the additional pieces of information are transmitted from the at least one autonomous or semi-autonomous vehicle to the external server using a car-to-x communication link, of a mobile radio communication link and/or of another wireless communication link.

9. A control unit for an autonomous or semi-autonomous vehicle, the control unit, comprising a computer, configured to:
detect pieces of information from surroundings of the autonomous or semi-autonomous vehicle during a drive using at least one surroundings sensor;
carry out a planning of an instantaneous travel trajectory of the autonomous or semi-autonomous vehicle based on the detected pieces of information obtained;
detect additional pieces of information from the surroundings of the autonomous or semi-autonomous vehicle using the at least one surroundings sensor during a stop caused by an instantaneous traffic situation and/or a traffic sign and/or another piece of traffic infrastructure, the detected additional pieces of information not being used for planning the instantaneous travel trajectory of the autonomous or semi-autonomous vehicle; and
convey the detected additional pieces of information, together with a respective geographical position at which the additional pieces of information have been detected, in in a form of data to an external server.

10. A system for ascertaining particular pieces of status information for at least one geographical position with in an aid of autonomous or semi-autonomous vehicles, comprising:
at least one autonomous or semi-autonomous vehicle; and
an external server;
wherein the at least one autonomous or semi-autonomous vehicle is configured to detect pieces of information from its surroundings during a drive using at least one surroundings sensor, and to carry out a planning of an instantaneous travel trajectory of the vehicle based on the detected pieces of information;
wherein the at least one autonomous or semi-autonomous vehicle is further configured to detect additional pieces of information from the surroundings of the at least one autonomous or semi-autonomous vehicle using the at least one surroundings sensor during a stop caused by an instantaneous traffic situation and/or a traffic sign and/or another piece of traffic infrastructure, the detected additional pieces of information not being used for planning the instantaneous travel trajectory of the at least one autonomous or semi-autonomous vehicle;
wherein the at least one autonomous or semi-autonomous vehicle is further configured to convey the detected additional pieces of information, together with a respective geographical position at which the additional pieces of information have been detected, in a form of data to the external server; and the external server is configured to ascertain at least one piece of status information for the respective geographical position with using the data received from the at least one autonomous or semi-autonomous vehicle.

11. The system as recited in claim 10 , wherein the vehicle or the external server includes an artificial intelligence.
