Abstract

A method for operating a GNSS sensor of a vehicle having control operations influenceable via an electronic control unit includes receiving satellite data, evaluating the satellite data, and deactivating at least one operating mode of the GNSS sensor when at least a portion of the satellite data is unsuitable for determining the position of the vehicle.

First claim

The invention claimed is:

1. A method for operating a GNSS sensor of a vehicle having control operations influenceable via an electronic control unit, wherein the GNSS sensor is configured to operate in a plurality of operating modes, each of the plurality of operating modes associated with a respective satellite system, the method comprising:
receiving satellite data associated with a first of the respective satellite systems;
evaluating the satellite data;
deactivating a first operating mode of the plurality of operating modes associated with the first of the respective satellite systems when at least a portion of the satellite data is unsuitable for determining the position of the vehicle;
reporting the deactivation of the first operating mode and geopositioning data externally to the vehicle to a superordinate system; and
reactivating, with the superordinate system, the deactivated first operating mode using an activation signal.

2. The method as claimed in claim 1 , wherein:
the received satellite data includes information indicating that the satellite data are faulty or corrupted; and
deactivating the first operating mode includes deactivating the first operating mode based on the information from the satellite data indicating that said data are faulty or corrupted.

3. The method as claimed in claim 1 , further comprising:
supplying information indicating that the satellite data are faulty or corrupted via a communication link, wherein deactivating the first operating mode includes deactivating the first operating mode based on the supplied information.

4. The method as claimed in claim 1 , wherein:
evaluating the satellite data includes evaluating the satellite data based upon an area in which the vehicle is located; and
deactivating the first operating mode includes deactivating the first operating mode when the vehicle is located in a predetermined area.

5. The method as claimed in claim 1 , further comprising:
receiving further satellite data associated with a second of the respective satellite systems;
evaluating the further satellite data; and
deactivating a second operating mode of the plurality of operating modes associated with a second of the respective satellite systems when at least a portion of the further satellite data is unsuitable for determining the position of the vehicle of the GNSS sensor while the first operating mode is deactivated.

6. The method of claim 1 , wherein the electronic control unit controls least one of the receiving, the evaluating, and the deactivating.

7. A method for operating a vehicle having control operations influenceable via an electronic control unit, comprising:
determining a position of the vehicle using a GNSS sensor, wherein the GNSS sensor is configured to operate in a plurality of operating modes, each of the plurality of operating modes associated with a respective satellite system, by
receiving satellite data associated with a first of the respective satellite systems,
evaluating the satellite data, determining at least a portion of the satellite data is unsuitable for determining the position of the vehicle, and
deactivating, prior to determining the position of the vehicle, an operating mode of the plurality of operating modes associated with the first of the respective satellite systems in response to the determination that the at least a portion of the satellite data is unsuitable for determining the position of the vehicle; and

limiting an influence of the electronic control unit on at least one of the control operations of the vehicle when the operating mode has been deactivated, wherein limiting the influence includes limiting a speed of the vehicle.

8. The method of claim 7 , further comprising:
deactivating a second operating mode of the plurality of operating modes associated with a second of the respective satellite systems when at least a portion of the further satellite data is unsuitable for determining the position of the vehicle of the GNSS sensor while the first operating mode is deactivated, and
disabling an autonomous driving mode of the vehicle when the second operating mode is deactivated while the first operating mode is deactivated.

9. A vehicle comprising:
a GNSS sensor configured to operate in a plurality of operating modes, each of the plurality of operating modes associated with a respective satellite system; and
an electronic control unit configured to
influence control operations of the vehicle,
receive satellite data associated with a first of the respective satellite systems,
evaluate the satellite data,
deactivate an operating mode of the plurality of operating modes when at least a portion of the satellite data is unsuitable for determining the position of the vehicle, and
limit an influence of the electronic control unit on at least one of the control operations of the vehicle when the operating mode has been deactivated, wherein control operations of the vehicle are influenceable via the electronic control unit, and wherein limiting the influence includes limiting a speed of the vehicle.

10. The vehicle of claim 9 , wherein:
the electronic control unit includes a computer program product; and
the electronic control unit is configured to execute the computer program product to receive the satellite data, evaluate the satellite data, and deactivate the operating mode.

11. The vehicle of claim 10 , wherein the computer program product is stored on a machine-readable storage medium.

12. The vehicle of claim 9 , wherein the electronic control unit is further configured to:
receive further satellite data associated with a second of the respective satellite systems;
evaluate the further satellite data;
deactivate a second operating mode of the plurality of operating modes associated with a second of the respective satellite systems when at least a portion of the further satellite data is unsuitable for determining the position of the vehicle of the GNSS sensor while the first operating mode is deactivated, and
disabling an autonomous driving mode of the vehicle when the second operating mode is deactivated while the first operating mode is deactivated.
