Abstract

A method for the satellite-supported determination of a position of a vehicle includes identifying a plurality of satellites which may be usable for determining a position of a vehicle and receiving data which characterize movable reception obstacles in a vicinity of the vehicle. The method includes determining a reduced selection of satellites from the plurality of satellites, based on the received data, and determining the position of the vehicle using signals which have been transmitted from the reduced selection of satellites.

First claim

The invention claimed is:

1. A method for satellite-supported determination of a position of a vehicle, the method comprising:
identifying a plurality of satellites that are usable for determining a position of a vehicle;
capturing, using at least one environmental sensor of the vehicle, first data that characterize movable reception obstacles in a vicinity of the vehicle, the movable reception obstacles including another vehicle in the vicinity of the vehicle;
receiving, from the other vehicle, second data that characterize the other vehicle, the second data including a spatial extent of the other vehicle;
determining a reduced selection of satellites from the plurality of satellites, based on the captured first data and the spatial extent of the other vehicle from the received second data; and
determining the position of the vehicle using signals which have been transmitted from the reduced selection of satellites.

2. The method as claimed in claim 1 , the determining the reduced selection of satellites further comprising:
determining a first group of satellites from the plurality of satellites the transmitted signals of which could be influenced by the movable reception obstacles based upon the captured first data and the received second data, the first group of satellites being excluded from the reduced selection of satellites.

3. The method as claimed in claim 1 , the determining the reduced selection of satellites further comprising:
determining a second group of satellites from the plurality of satellites that are at an angle with respect to the horizon which is smaller than a predetermined minimum angle of inclination, the second group of satellites being excluded from the reduced selection of satellites.

4. The method as claimed in claim 1 , wherein the first data captured by the at least one environmental sensor of the vehicle also characterize immovable reception obstacles in the vicinity of the vehicle.

5. The method as claimed in claim 4 further comprising:
receiving, from a respective one of the immovable reception obstacles, third data that characterize the respective one of the immovable reception obstacles, the third data including at least one of (i) a type of obstacle, (ii) a location, (iii) a position, and (iv) a spatial extent of the respective one of the immovable reception obstacles.

6. The method as claimed in claim 1 , wherein the at least one environmental sensor of the vehicle includes at least one of (i) an ultrasonic sensor, (ii) a RADAR sensor, (iii) a LIDAR sensor, and (iv) a camera sensor.

7. A position sensor for satellite-supported determination of a position of a vehicle, comprising:
a machine-readable storage medium including program instructions stored therein; and
a processor operably connected to the machine-readable storage medium and configured to execute the stored program instructions to:
identify a plurality of satellites that are usable for determining a position of the vehicle;
receive, from at least one environmental sensor of the vehicle, first data that characterize movable reception obstacles in a vicinity of the vehicle, the movable reception obstacles including another vehicle in the vicinity of the vehicle;
receive, from the other vehicle, second data that characterize the other vehicle, the second data including at least one of a speed and acceleration of the other vehicle;
determine a reduced selection of satellites from the plurality of satellites, based on the received first data and the at least one of the speed and the acceleration of the other vehicle from the received second data; and
determine the position of the vehicle using signals which have been transmitted from the reduced selection of satellites.
