A method for assisting a brake system with a reduced effectiveness of the vehicle brake system

摘要

The invention relates to a method for active brake pressure or brake force support of a brake system during reduced effectiveness of a brake system of a vehicle, wherein active support is brought about by means of a so-called overboost function that causes an increase in brake pressure or brake force by switching on an energy or pressure source, wherein triggering of said overboost function is limited to situations in which certain predetermined criteria are fulfilled. The predetermined criteria are advantageously taken into account in order to determine an overboost activation threshold. If said threshold is exceeded, active support is then initiated.
