Abstract

A method for determining a driving maneuver for a motor vehicle includes the steps of ascertaining an imminent accident with an external object, ascertaining characteristic variables for accident damages in different driving maneuvers and determining the driving maneuver whose characteristic variable is indicative of the least accident damage.

Claims

1. A method for determining a driving maneuver for a motor vehicle, the method comprising:

ascertaining an imminent accident with an external object;

ascertaining characteristic variables for accident damages with different driving maneuvers; and

determining the driving maneuver whose characteristic variable is indicative of the least accident damage.

2. The method of claim 1, wherein one of the driving maneuvers is the instantaneous driver-controlled driving maneuver and the driving maneuver whose characteristic variable is the farthest below the characteristic variable of the instantaneous driving maneuver is determined.

3. The method of claim 1, wherein each characteristic variable relates to a probability of an accident damage, which is greater than a predetermined value.

4. The method of claim 1, wherein the motor vehicle is controlled to carry out the driving maneuver thereby determined.

5. The method of claim 1, wherein a collision speed of the motor vehicle with the object is determined for each driving maneuver, and the characteristic numbers are determined on the basis of the collision speeds.

6. The method of claim 1, wherein a distribution density of collision speeds of the motor vehicle with the object is determined for each driving maneuver, and the characteristic numbers are determined based on the distribution densities.

7. The method of claim 1, wherein the object includes a person and the characteristic numbers each take into account an arrangement of transportation of the person.

8. The method of claim 1, wherein the characteristic variables are based on personal injuries.

9. The method of claim 1, wherein the characteristic numbers take into account a collision point of the object on the motor vehicle.

10. A computer readable medium having a computer program, which is executable by a processor, comprising:

a program code arrangement having program code for determining a driving maneuver for a motor vehicle, by performing the following;

ascertaining an imminent accident with an external object;

ascertaining characteristic variables for accident damages with different driving maneuvers; and

determining the driving maneuver whose characteristic variable is indicative of the least accident damage.

11. A device for determining a driving maneuver for a motor vehicle, comprising:

a detection unit for detecting an external object; and

a processing unit for determining the driving maneuver for the motor vehicle, by performing the following;

ascertaining an imminent accident with an external object;

ascertaining characteristic variables for accident damages with different driving maneuvers; and

determining the driving maneuver whose characteristic variable is indicative of the least accident damage.
