Abstract

A method for determining initial data for determining position data of a vehicle based on driving dynamics data, the method including: assigning a determined environment status at a determined position of the vehicle to the determined position of the vehicle; detecting on environment status; and—using the determined position as initial data if a contrast of the detected environment status and the determined environmental status satisfies a predetermined condition.

Claims

1. A method for determining initial data for determining position data of a vehicle on a basis of vehicle-dynamics data, comprising:

in response to the vehicle being turned OFF, detecting a first ambient condition in proximity of the vehicle and associating the first ambient condition with a defined position of the vehicle,

in response to the vehicle being turned ON;

detecting a second ambient condition in the proximity of the vehicle,

comparing the first ambient condition to the second ambient condition, and

when the comparison satisfies a predetermined condition, using the defined position as initial data indicating a current position of the vehicle.

2. The method as claimed in claim 1, wherein the defined position of the vehicle is a position at which the vehicle is switched off.

3. A method as claimed in claim 2, wherein the detected ambient condition after the switching-off and a system restart of the vehicle is detected at the defined position.

4. The method as claimed in claim 1, wherein the defined ambient condition comprises at least a portion of an image of a surrounding area of the vehicle.

5. The method as claimed in claim 4, wherein the portion of the image of the surrounding area of the vehicle is detected by surround sensors.

6. The method as claimed in claim 5, wherein the portion of the image of the surrounding area of the vehicle is detected in a plane outside a movement plane of the vehicle.

7. The method as claimed in claim 5, wherein the portion of the image of the surrounding area of the vehicle is detected by means of object recognition.

8. The method as claimed in claim 4, wherein the portion of the image of the surrounding area of the vehicle is detected in a plane outside a movement plane of the vehicle.

9. The method as claimed in claim 8, wherein the portion of the image of the surrounding area of the vehicle is detected by means of object recognition.

10. The method as claimed in claim 4, wherein the portion of the image of the surrounding area of the vehicle is detected by means of object recognition.

11. A method for determining initial data for determining position data of a vehicle on a basis of vehicle-dynamics data, comprising:

in response to the vehicle being turned OFF, detecting a first ambient condition in proximity of the vehicle and associating the first ambient condition with a defined position of the vehicle,

in response to the vehicle being turned ON;

detecting a second ambient condition in the proximity of the vehicle,

comparing the first ambient condition to the second ambient condition, and

when the comparison satisfies a predetermined condition, using the defined position as initial data indicating a current position of the vehicle,

acquiring vehicle-dynamics data, and

updating the current position by extrapolating the initial data on the basis of the vehicle-dynamics data.

12. A control device, which is designed to implement a method for determining initial data for determining position data of a vehicle on the basis of vehicle-dynamics data, comprising:

in response to the vehicle being turned OFF, detecting a first ambient condition in proximity of the vehicle and associating the first ambient condition with a defined position of the vehicle,

in response to the vehicle being turned ON;

detecting a second ambient condition in the proximity of the vehicle,

comparing the first ambient condition to the second ambient condition, and

when the comparison satisfies a predetermined condition, using the defined position as initial data indicating a current position of the vehicle.
