Abstract

Sensor information is processed in a vehicle by transforming sensor data acquired with at least one sensor of the vehicle from a current environment of the vehicle into a curved coordinate system, by continuously updating the sensor data while the vehicle is moving, and by dynamically adapting the curved coordinate system to a current situation of the vehicle.

Claims

1. A method for processing sensor information in a vehicle, comprising:

transforming sensor data acquired with at least one sensor of the vehicle from a current environment of the vehicle into a curved coordinate system,

continuously updating the sensor data while the vehicle is moving, and

dynamically adapting the curved coordinate system to a current situation of the vehicle.

2. The method of claim 1, further comprising adapting at least one component of at least one automatic vehicle control system of the vehicle to the current environment of the vehicle depending on current data entered in the curved coordinate system.

3. The method of claim 1, wherein the curved coordinate system comprises a polar grid.

4. The method of claim 1, wherein the current situation of the vehicle includes at least one of a vehicle dynamics and the current environment of the vehicle.

5. The method of claim 1, wherein the current environment includes trajectories of the vehicle in the current environment.

6. The method of claim 1, wherein the curved coordinate system is matched to a route to be traveled.

12. The method according to claim 1, wherein the current situation of the vehicle comprises at least one of a rotational and translational movement of the vehicle in a defined time interval.

7. A method for controlling a vehicle, comprising:

transmitting sensor data of a current environment of the vehicle acquired by at least one sensor of the vehicle to a central control unit of the vehicle,

transforming with the central control unit the transmitted sensor data into a curved coordinate system that is dynamically adapted to a current situation of the vehicle, and

controlling at least one component of the vehicle with the sensor data that were transformed into the curved coordinate system.

8. The method of claim 7, wherein the at least one component of the vehicle comprises a component selected from an active suspension, brakes, an engine, a steering system and a driver information system.

9. The method of claim 7, further comprising

processing the transmitted and transformed sensor data in the central control unit, and

transmitting the processed sensor data to the at least one component of the vehicle.

10. The method of claim 7, further comprising

transmitting the transmitted and transformed sensor data to at least one control device of the at least one component of the vehicle, and

processing the transmitted and transformed sensor data with the respective control device.

11. The method of claim 7, further comprising taking into account the already acquired and transformed sensor data in calculations for controlling respective components of the vehicle.

13. The method according to claim 7, wherein the current situation of the vehicle comprises at least one of a rotational and translational movement of the vehicle in a defined time interval.

14. A vehicle comprising:

at least one sensor for detecting a current environment of the vehicle, and

a central control unit configured to transform sensor data acquired by the at least one sensor into a curved coordinate system, and to dynamically parameterize the curved coordinate system depending on a current situation of the vehicle.
