Abstract

A method for determining an accident risk of a first object with at least one second object is proposed, a collision probability and a hazard probability of the at least one second object being determined in a predefined region around the first object, the collision probability and the hazard probability being determined as a function of motions and object classes of the first and the at least one second object. The accident risk is then determined as a function of the collision probability and the hazard probability.

Claims

1. A method for determining an accident risk of a first object with at least one second object, comprising:

determining the accident risk as a function of a collision probability and a hazard probability of the at least one second object in a predefined region, and determining the collision probability and the hazard probability as a function of motions of the first and at least one second object.

2. The method according to claim 1, wherein an object class of the first and at least one second object are taken into account in determining the collision probability and the hazard probability.

3. The method according to claim 2, wherein the motion and the object class of the at least one second object are determined by way of a sensor suite, and the motion and the object class of the first object are retrieved from at least one data source.

4. The method according to claim 2, wherein the motion of the first object is defined by at least one current position and its velocity.

5. The method according to claim 2, wherein the motion of the at least one second object is defined by at least one current position.

6. The method according to claim 1, wherein the motion and the object class of the at least one second object are determined by way of a sensor suite, and the motion and the object class of the first object are retrieved from at least one data source.

7. The method according to claim 6, wherein the motion of the at least one second object is defined by at least one current position.

8. The method according to claim 1, wherein the motion of the first object is defined by at least one current position and its velocity.

9. The method according to claim 8, wherein the motion of the at least one second object is defined by at least one current position.

10. The method according to claim 8, wherein the motion of the first object is additionally determined by way of at least one of its first longitudinal acceleration, first transverse acceleration, a first rotation angle and a first steering angle.

11. The method according to claim 10, wherein at least one of environmental influences and a respective driving behavior are taken into account in determining the respective motion.

12. The method according to claim 1, wherein the motion of the at least one second object is defined by at least one current position.

13. The method according to claim 12, wherein the motion of the at least one second object is determined by at least one of its velocity relative to the first object, a second longitudinal acceleration, a second transverse acceleration and a second rotation angle.

14. The method according to claim 13, wherein at least one of environmental influences and a respective driving behavior are taken into account in determining the respective motion.

15. The method according to claim 1, wherein at least one of an indication and at least one signal to an actuator suite are generated as a function of the accident risk.

16. The method according to claim 1, wherein an object class of the first and at least one second object are taken into account in determining the collision probability and the hazard probability, wherein the motion and the object class of the at least one second object are determined by way of a sensor suite, and the motion and the object class of the first object are retrieved from at least one data source, wherein the motion of the first object is defined by at least one current position and its velocity, wherein the motion of the at least one second object is defined by at least one current position.

17. The method according to claim 16, wherein the motion of the first object is additionally determined by way of at least one of its first longitudinal acceleration, first transverse acceleration, a first rotation angle and a first steering angle, and wherein the motion of the at least one second object is determined by at least one of its velocity relative to the first object, a second longitudinal acceleration, a second transverse acceleration and a second rotation angle.

18. The method according to claim 16, wherein at least one of environmental influences and a respective driving behavior are taken into account in determining the respective motion, and wherein at least one of an indication and at least one signal to an actuator suite are generated as a function of the accident risk.
