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 (16)

1. A method for setting a brake system of a vehicle in which in the event of a collision, a braking force is built up automatically, the method comprising: determining a position of the collision on the vehicle based on an evaluation of a triggering of at least one airbag in the vehicle, wherein the position of the collision on the vehicle is a location on the vehicle where it is impacted; and implementing an automatic build-up of the 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 wherein in the event of a collision in a front section of the vehicle a delayed braking is implemented; wherein the type of collision is taken into account, including a rear impact, a frontal impact, and a lateral impact, to influence the automatic braking force build-up or idle time with regard to the beginning of the braking force build-up, a gradient of the braking force build-up, and a maximum achievable level of the braking force, wherein the automatically built-up braking force can be suspended through a reaction of a driver, and wherein the reaction of the driver is activation of the acceleration pedal, and wherein parameters relating to the braking force build-up are set according to the type of collision.

2. The method as recited in claim 1 , wherein the gradient of the braking force build-up is influenced as a function of the position of the collision.

3. The method as recited in claim 1 , wherein the braking force build-up takes place in a delayed manner.

4. The method as recited in claim 3 , wherein the delayed manner is influenced as a function of the position of the collision.

5. The method as recited in claim 1 , wherein the braking force build-up takes place in an accelerated manner via prefilling of a braking unit with hydraulic medium.

6. The method as recited in claim 1 , wherein the braking force maximum is influenced as a function of the position of the collision.

7. The method as recited in claim 1 , wherein the position of the collision is determined via a surroundings sensor system.

8. The method as recited in claim 7 , wherein the surroundings sensor system is optical sensors, radar or ultrasound sensors.

9. The method as recited in claim 1 , wherein in the event of a collision in the front section of the vehicle the delayed braking is implemented after the collision in the front section.

10. The method as recited in claim 7 , wherein the surroundings sensor system determines the position of the collision before the event of the collision.

11. The method as recited in claim 1 , wherein the braking force build-up takes place as a function of a current traffic situation.

12. A control device for setting a brake system of a vehicle in which in the event of a collision, a braking force is built up automatically, comprising: a determining arrangement to determine a position of the collision on the vehicle based on an evaluation of a triggering of at least one airbag in the vehicle; and an implementing arrangement to implement an automatic build-up of the 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, wherein in the event of a collision in a front section of the vehicle a delayed braking is implemented, and wherein the position of the collision on the vehicle is a location on the vehicle where it is impacted wherein the type of collision is taken into account, including a rear impact, a frontal impact, and a lateral impact, to influence the automatic braking force build-up or idle time with regard to the beginning of the braking force build-up, a gradient of the braking force build-up, and a maximum achievable level of the braking force, wherein the automatically built-up braking force can be suspended through a reaction of a driver, and wherein the reaction of the driver is activation of the acceleration pedal, and wherein parameters relating to the braking force build-up are set according to the type of collision.

13. A brake system, comprising: a control device for setting a brake system of a vehicle in which in the event of a collision, a braking force is built up automatically, including: a determining arrangement to determine a position of the collision on the vehicle based on an evaluation of a triggering of at least one airbag in the vehicle; and an implementing arrangement to implement an automatic build-up of the 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, wherein in the event of a collision in a front section of the vehicle a delayed braking is implemented, and wherein the position of the collision on the vehicle is a location on the vehicle where it is impacted; wherein the type of collision is taken into account, including a rear impact, a frontal impact, and a lateral impact, to influence the automatic braking force build-up or idle time with regard to the beginning of the braking force build-up, a gradient of the braking force build-up, and a maximum achievable level of the braking force, wherein the automatically built-up braking force can be suspended through a reaction of a driver, and wherein the reaction of the driver is activation of the acceleration pedal, and wherein parameters relating to the braking force build-up are set according to the type of collision.

14. The brake system as recited in claim 13 , wherein the automatic build-up of braking force takes place via actuating signals of an ESP control device.

15. The brake system as recited in claim 13 , further comprising:

an airbag control device for controlling a functioning of at least one airbag in the vehicle.
