Embodiment Construction

[0023] figure 1 The basic structure of a compensating system 10 for compensating an insufficient pressure build-up in a brake system 12 of a vehicle (the vehicle as a whole is not shown) is shown. The brake system 12 has an actuating element 16 configured as a brake pedal 14 , a brake booster 18 , a master cylinder 20 , wheel brakes 22 with a brake calliper 24 each having a brake cylinder and a brake disc 26 (only shown Two of them) as well as an assembly 28 configured as an ESP assembly (ESP: Electronic Stability Program) for an additional pressure build-up in the brake system 12 . Master cylinder 20 is connected on the one hand to actuating element 16 via brake booster 18 and on the other hand is hydraulically connected to brake cylinders of wheel brakes 22 via brake lines 30 and brake system 12 .

[0024] Compensation system 10 has, in addition to assembly 28, sensor 32 for continuously or periodically ascertaining the real-time position of actuating element 16 over its ad...

Abstract

The invention relates to a braking system for a vehicle, in particular a motor vehicle, in the event of a malfunction or failure of a braking force booster (18) for braking force support when an actuating element (16) of the braking system (12) is actuated. 12) Method for compensating for insufficient pressure build-up in the brake system (12) by means of an assembly (28) for additional pressure build-up and depending on the actuation element (16) over its adjustment travel position to trigger this compensation. It is provided that the real-time position of the actuating element ( 16 ) over the actuating path is determined continuously or periodically, and the triggering and the additional pressure build-up are carried out as a function of this determined real-time position. The invention also relates to a corresponding compensation system (10).

Description

technical field [0001] The invention relates to a method for compensating for an insufficient pressure build-up in the brake system of a vehicle in the event of a failure or failure of a brake booster for brake force support when an actuating element of the brake system is actuated. The invention also relates to a system for compensating for an insufficient pressure build-up in the brake system of a vehicle in the event of a failure or failure of a brake booster for brake force support when an actuating element of the brake system is actuated. Background technique [0002] The braking system of a vehicle, especially a motor vehicle, is used to reduce the speed of the vehicle, to bring the vehicle to a stop or to hold the vehicle at a standstill. The brake system has at least one actuating device, which introduces an action into the brake system and controls it. Such an actuating device, for example a brake pedal, can be actuated mechanically by the user / driver of the vehicl...
