Patent ID: 8762020

Claim:
A method for increasing a braking effect in a motor vehicle having a hydraulic brake system, wherein an on an energy supply unit, which is used to increase the brake pressure in at least one wheel brake, when a brake pressure adjusted by a driver in a master brake cylinder exceeds a first activation threshold, which is determined depending on a detected vehicle deceleration, and the energy supply unit is switched off when the brake pressure reaches a predetermined bottom threshold value at a specific instant, the method comprising: checking within an interval beginning at that specific instant whether the brake pressure (p TMC ) rises using at least one of a comparison between the brake pressure and a second activation threshold (p AT,red ) that is reduced compared to the first activation threshold (p AT ) and using a comparison between a brake pressure gradient and a predetermined threshold value; and switching the energy supply unit ( 9 , 10 ) to on again when a new rise of the brake pressure (p TMC ) has been detected.
