Abstract

A method for operating a brake installation of a vehicle. A first electrically controllable pressure provision device provides brake pressure for actuating hydraulically actuatable brakes. A first electronic open-loop and closed-loop control unit, and a first pressure detection device, measures brake pressure provided by a primary brake system. A secondary brake system between the primary system and a part of the wheel brakes has a second electrically controllable pressure provision device provides brake pressure for actuating at least the part of the brakes. A second electronic open-loop and closed-loop control unit, and at least one second pressure detection device, the signals of which are processed in the second electronic open-loop and closed-loop control unit. The secondary system monitors the primary system based on signals from the second pressure detection device and on a predefined brake pressure demand to build up a brake pressure corresponding to the predefined brake pressure demand.
