Abstract
A method for improving the efficiency of a driving dynamics regulating system which intervenes in the driving operation in critical driving situations by automatic braking intervention at selected wheels. It is possible for the reaction speed of the brake system 3 to be considerably increased if, before the actual regulating intervention, the imminent critical driving situation is already detected and a slight preparatory brake pressure is already built up at at least one wheel at which a future regulating intervention is expected.

9. A method for stabilizing a vehicle in a critical driving situation, comprising:
-
detecting the critical driving situation by a sensor system;
causing a regulating algorithm to intervene in a driving operation of the vehicle under a predefined condition using a brake system; and
before a stabilization intervention, building up a preparatory brake pressure of a low level at a wheel brake of a wheel at which the stabilization intervention is shortly expected. - View Dependent Claims (10, 11, 12, 13, 14, 15)

16. A driving dynamics regulating system for stabilizing a vehicle in a critical driving situation, comprising:
-
a control unit in which a driving dynamics regulating algorithm is stored;
a sensor system for registering variables describing a driving condition; and
a brake system for performing a stabilization intervention, wherein, before the stabilization intervention, the control unit already activates a wheel brake of a wheel at which stabilization intervention is shortly expected and builds up a preparatory brake pressure of a low level.
