## Abstract

A method for controlling a vehicle system of a vehicle which is equipped to carry out an automated driving operation involves localizing the vehicle and approving the vehicle system for activation depending on a result of the localization. The vehicle is localized with at least two different localization methods. The at least two localization methods include at least one landmark-based localization method and one localization method based on at least one global navigation satellite system. The vehicle system is only approved for activation if it is confirmed with each of the applied localization methods that the vehicle is located on a route section approved for automated driving operation.

## Claims

### Claim 1

A method for controlling a vehicle system of a vehicle, which is equipped to perform automated driving operation, the method comprising:
localizing the vehicle with at least two different localization methods, wherein the at least two localization methods comprise at least one landmark-based localization method and one localization method based on at least one global navigation satellite system; and
approving the vehicle system for activation depending on a result of the localization, wherein the vehicle system is only approved for activation if it is confirmed with each of the applied localization methods that the vehicle is located on a route section approved for automated driving operation.

### Claim 2 (depends on 1)

The method of claim 1, wherein the landmark-based localization method comprises:
comparing sensor-determined landmark signatures with landmark signatures takes from a digital map to determine a most probable position of the vehicle in the digital map and a similarity measure of the comparison of sensor-determined landmark signatures with landmark signatures.

### Claim 3 (depends on 2)

The method of claim 2, wherein a confirmation that the vehicle is located on a route section approved for automated driving operation is only issued if
the determined most probable position is located on the route section approved for automated driving operation, and
the determined similarity measure exceeds a predetermined similarity threshold.

### Claim 4 (depends on 2)

The method of claim 2, further comprising:
comparing the determined most probable position with a position determined by the localization method based on the at least one global navigation satellite system.

### Claim 5 (depends on 4)

The method of claim 4, wherein the determined most probable position is evaluated as plausible if the determined most probable position and the position determined by the localization method based on the at least one global navigation satellite system are within a predetermined maximum distance from each other.

### Claim 6 (depends on 5)

The method of claim 5, wherein a confirmation that the vehicle is on a route section approved for automated driving operation is only issued if the determined most probable position has been evaluated as plausible.

### Claim 7 (depends on 1)

The method of claim 1, wherein the localization method based on at least one global navigation satellite system comprises:
determining a current position of the vehicle using the at least one global navigation satellite system;
determining an upper error limit for an expected deviation of an actual vehicle position from the current position of the vehicle determined using the at least one global navigation satellite system;
defining a target limit in such a way that an area encompassed by the target limit does not encompass areas of adjacent roads,
wherein a confirmation that the vehicle is on a route section approved for automated driving operation is only issued if the determined upper error limit lies within the area encompassed by the target limit.

### Claim 8 (depends on 2)

The method of claim 2, wherein the landmark-based localization method comprises:
downloading, by the vehicle, a map section of the digital map from a server external to the vehicle, wherein the map section is assigned to a current position of the vehicle, and wherein the current position of the vehicle is determined by the localization method based on the at least one global navigation satellite system.

### Claim 9

A device for controlling a vehicle system of a vehicle, which is equipped to perform automated driving operation, the device comprising:
a global navigation satellite system receiver;
a vehicle sensor system; and
a processing unit coupled to the global navigation satellite system receiver and the vehicle sensor system, wherein the processing unit is configured to
localize the vehicle using a landmark-based localization using information from the vehicle sensor system and a localization based on signals received by the global navigation satellite system receiver; and
approve the vehicle system for activation depending on a result of the localization, wherein the vehicle system is only approved for activation if it is confirmed that the localizations using the landmark-based localization based on the signals received by the global navigation satellite system receiver both indicate that the vehicle is located on a route section approved for automated driving operation.
