Abstract

The invention relates to an electrohydraulic braking system (1) for a motor vehicle and a method for operating an electrohydraulic braking system (1), comprising: Brake master cylinder (2) operated by pedal (1a) for actuating the wheel brakes (8, 9, 10, 11); electronically controllable pressure supply device (5); electronically controllable additional brake actuator (50); The control and regulation unit (12), wherein, in the normal mode of operation, the control and regulation unit (12) detects a brake request on the basis of the driver's operation of the brake pedal (1a) and The brake (8, 9, 10, 11) builds up the braking torque on the brake (8, 9, 11) and controls the pressure supply device (5), wherein the driver intervenes directly in the wheel brake (8, 9, 10, 11) and the control and regulation unit (12) controls the additional brake actuator (50) in order to build up the braking torque, wherein, in standby mode, the control and regulation unit (12) monitors the brake pedal travel and An additional brake actuator is controlled to build up a braking torque for a given pedal travel threshold (120), wherein the pedal travel threshold (120) is increased at least once during a sequence of brake pedal actuations by the driver.

Description

technical field [0001] The invention relates to an electrohydraulic braking system according to the preamble of claim 1 . The invention also relates to a method for operating an electrohydraulic brake system. Background technique [0002] In motor vehicle technology, "brake-by-wire" braking devices are becoming more and more popular. Such a brake system usually comprises, in addition to the brake master cylinder, which can be operated by the driver of the vehicle, an electrically ("by-wire") controllable pressure supply device, by means of which in the "brake-by-wire" operating mode to operate the wheel brakes. [0003] In such modern braking systems, in particular electrohydraulic braking systems with the "brake-by-wire" operating mode, the driver is decoupled from direct intervention on the brakes. When the pedal is actuated, the pedal decoupling unit and the simulator are frequently actuated, wherein the driver's desire to brake is detected by a sensor system. The ped...
