Method for determining initial data for determining position data of a vehicle
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.
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.
