Abstract
A braking system, in particular for a motor vehicle, including a braking force device having a brake booster for boosting a braking force and a brake pressure supply device for providing brake pressure with the aid of a brake medium, a braking device which may be acted on by pressure by the brake medium with the aid of the brake pressure supply device, and at least one sensor which is designed to detect a distance differential of a displacement means for the displacement of a volume of the brake medium of the braking force device. The braking force device is designed to ascertain the volume of brake medium to be displaced on the basis of the detected distance differential.
Claims18
A braking system, comprising:
- a braking force device having a brake booster for boosting a braking force and a brake pressure supply device for providing a brake pressure via a brake medium;
- a braking device which may be acted on by pressure by the brake medium via the brake pressure supply device;
- a displacement arrangement for displacing a volume of the brake medium;
- and
- at least one sensor for detecting a distance differential of the displacement arrangement, wherein the braking force device ascertains the volume of the brake medium to be displaced on the basis of the detected distance differential;
- and
- a compensation arrangement for at least one of supplying and discharging a volume of brake medium at least one of to and from the braking device as a function of the ascertained volume of the brake medium to be displaced.
A method for regulating a pressure of a brake medium in a braking system, comprising:
- specifying a braking force;
- boosting the braking force;
- providing the boosted braking force with the aid of brake pressure in a braking device by a volume displacement of the brake medium;
- detecting the volume displacement of the brake medium via a distance differential of a displacement arrangement;
- and
- actuating a compensation arrangement to at least one of supply and discharge a brake medium volume of the braking device, wherein the volume of the brake medium at least one of supplied and discharged by the compensation arrangement is a function of the detected volume.
A method of using a braking system that includes a braking force device having a brake booster for boosting a braking force and a brake pressure supply device for providing a brake pressure via a brake medium;
- a braking device which may be acted on by pressure by the brake medium via the brake pressure supply device;
