Abstract

In a method for setting a brake system of a vehicle, braking force is built up automatically in the event of a collision. In the process, the position of the collision on the vehicle is determined and the build-up of braking force is implemented as a function of the position of the collision.

Claims

1-13. -13. (canceled)

14. A method for setting a brake system of a vehicle in which in the event of a collision, braking force is built up automatically, comprising:

determining a position of the collision on the vehicle and implementing automatic build-up of braking force as a function of the position of the collision, wherein in the event of a collision in a rear section of the vehicle the vehicle is immediately decelerated, and in the event of a collision in a front section of the vehicle a delayed braking is implemented.

15. The method as recited in claim 14, wherein a gradient of the braking force build-up is influenced as a function of the position of the collision.

16. The method as recited in claim 14, wherein the braking force build-up takes place in a delayed manner.

17. The method as recited in claim 14, wherein the braking force build-up takes place in an accelerated manner via prefilling of a braking unit with hydraulic medium.

18. The method as recited in claim 14, wherein a braking force maximum is influenced as a function of the position of the collision.

19. The method as recited in claim 14, wherein the position of the collision is determined via triggering of an airbag in the vehicle.

20. The method as recited in claim 14, wherein the position of the collision is determined via a surroundings sensor system.

21. The method as recited in claim 20, wherein the surroundings sensor system is optical sensors, radar or ultrasound sensors.

22. The method as recited in claim 14, wherein the automatically built-up braking force can be suspended through a reaction of the driver.

23. The method as recited in claim 22, wherein the reaction of the driver is activation of the acceleration pedal.

24. A control device for implementing the method as recited in claim 14.

25. A brake system which includes a control device as recited in claim 24.

26. The brake system as recited in claim 25, wherein the automatic build-up of braking force takes place via actuating signals of an ESP control device.
