1. A method for GNSS-based locating of a vehicle having a GNSS location device in view of integrity information provided in relation to GNSS correction data, the method comprising:

a) receiving with a GNSS receiver in the vehicle GNSS correction data configured to correct for atmospheric delays for GNSS-based locating of a vehicle from a GNSS correction data provision system;

b) receiving with the GNSS receiver in the vehicle at least one piece of integrity information about a reliability of the GNSS correction data from the GNSS correction data provision system;

c) evaluating with the GNSS receiver in the vehicle the at least one piece of integrity information;

d) influencing with the GNSS receiver in the vehicle the GNSS-based locating of the vehicle based on the evaluation from step c);

e) transmitting the influenced GNSS-based locating of the vehicle from the GNSS receiver in the vehicle to a control unit of the vehicle; and

f) controlling the vehicle using the transmitted influenced GNSS-based locating of the vehicle, wherein

the influencing is different depending on whether the at least one piece of integrity information describes (i) a disturbance that concerns a specific GNSS satellite, (ii) a disturbance that concerns a position of the specific GNSS satellite, or (iii) a disturbance that concerns at least one propagation path between the specific GNSS satellite and the vehicle.

2. The method according to claim 1 , the d) influencing further comprising:

influencing the GNSS-based locating of the vehicle relatively more in response to at least one of satellite-constellation-specific and satellite-specific integrity information having been evaluated in step c), compared to in response to atmosphere-specific integrity information having been evaluated in step c).

3. The method according to claim 1 , the d) influencing further comprising:

continuing to operate the GNSS-based locating of the vehicle in an adapted manner in response to atmosphere-specific integrity information having been evaluated in step c) wherein information about the reliability of a location result is adapted.

4. The method according to claim 3 , the d) influencing further comprising:

adapting the GNSS-based locating of the vehicle by at least one of (i) selecting suitable GNSS satellites and (ii) weighting available GNSS satellite signals.

5. The method according to claim 1 , the d) influencing further comprising:

interrupting the GNSS-based locating of the vehicle in response to satellite-constellation-specific integrity information having been evaluated in step c).

6. The method according to claim 1 further comprising:

outputting with the GNSS receiver in the vehicle a warning message based on the influencing of step d).

7. The method according to claim 1 , wherein the method is carried out by executing a computer program.

8. A non-transitory machine-readable storage medium that stores a computer program for GNSS-based locating of a vehicle having a GNSS location device in view of integrity information provided in relation to GNSS correction data, the computer program configured to, when executed:

a) receive with the GNSS location device GNSS correction data configured to correct for atmospheric delays for GNSS-based locating of a vehicle from a GNSS correction data provision system;

b) receive with the GNSS location device at least one piece of integrity information about a reliability of the GNSS correction data from the GNSS correction data provision system;

c) evaluate with the GNSS location device the at least one piece of integrity information;

d) influence with the GNSS location device the GNSS-based locating of the vehicle based on the evaluation from step c);

e) transmit the influenced GNSS-based locating of the vehicle from the GNSS location device to a control unit of the vehicle; and

f) control the vehicle using the transmitted influenced GNSS-based locating of the vehicle, wherein

the influence is different depending on whether the at least one piece of integrity information describes (i) a disturbance that concerns a specific GNSS satellite, (ii) a disturbance that concerns a position of the specific GNSS satellite, or (iii) a disturbance that concerns at least one propagation path between the specific GNSS satellite and the vehicle.

9. A GNSS location device for GNSS-based locating of a vehicle having a GNSS location device in view of integrity information provided in relation to GNSS correction data, the GNSS location device configured to:

a) receive with the GNSS location device GNSS correction data configured to correct for atmospheric delays for GNSS-based locating of a vehicle from a GNSS correction data provision system;

b) receive with the GNSS location device at least one piece of integrity information about a reliability of the GNSS correction data from the GNSS correction data provision system;

c) evaluate with the GNSS location device the at least one piece of integrity information;

d) influence with the GNSS location device the GNSS-based locating of the vehicle based on the evaluation from step c);

e) transmit the influenced GNSS-based locating of the vehicle from the GNSS location device to a control unit of the vehicle; and

f) control the vehicle using the transmitted influenced GNSS-based locating of the vehicle, wherein

the influence is different depending on whether the at least one piece of integrity information describes (i) a disturbance that concerns a specific GNSS satellite, (ii) a disturbance that concerns a position of the specific GNSS satellite, or (iii) a disturbance that concerns at least one propagation path between the specific GNSS satellite and the vehicle.
