Embodiment Construction

[0028] figure 1 An exemplary braking system is schematically shown in. The brake system includes an operating device that can be operated by the driver of the vehicle by means of the operation or brake pedal 1, a pressure medium storage container 3 allocated to the operating device 2, an electrically controllable pressure providing device 4, and an electrically controllable pressure A modulation device 5 and an electronic control and regulation unit 7 (ECU: electronic control unit). The output connection of the pressure modulation device is connected to a wheel brake 6 of a motor vehicle not shown. The electronic control and regulation unit is used For processing sensor signals and controlling electronically controllable components.

[0029] The operating device 2 includes a dual-circuit brake master cylinder or tandem master cylinder 12, which has two hydraulic pistons 8 arranged one after another in a (brake master cylinder) housing. 9. The piston defines the boundary of the h...

Abstract

The invention relates to a method for operating a brake system for motor vehicles, comprising a master brake cylinder (12) that can be acuated by means of a brake pedal (1) and is separably (14a, 14b) connected to at least one hydraulically acutuatable wheel brake (6) by means of at least one brake circuit (I, II), a hydraulically operable pedal travel simulator (19) that is or can be connected to the master brake cylinder (12), an electrically controllable pressure provision apparatus (4) that is separably (27a, 27b) connected to the brake circuit (I, II), and an electronic open-loop and closed-loop control unit (7), wherein when the brake pedal (1) is actuated, a pressure (Ptarget) of the pressure provision apparatus (4) is applied to the brake circuit (I, II) in a first operating mode (ZA) and the pressure (PTHZ) of the master brake cylinder (12) is applied to the brake circuit (I, II) in a second operating mode (ZP), and wherein in the event of a transition from the second operating mode (ZP) to the first operating mode (ZA) while the brake pedal (1) is actuated, the actuation travel (SPedal) of the brake pedal (1) is adjusted by means of electronic open-loop or closed-loop control. The invention further relates to a brake system.

Description

Technical field [0001] The invention relates to a method according to the preamble of claim 1 and a braking system according to the preamble of claim 14. Background technique [0002] In motor vehicle technology, "brake-by-wire" braking systems are becoming more and more popular. This kind of brake system usually includes an electrically controllable pressure supply device in addition to the brake master cylinder that can be operated by the driver of the vehicle, by means of which the wheel brakes or brakes are performed in the "brake-by-wire" operating mode. Start the operation of the master cylinder. In order to deliver a suitable pedal feel to the vehicle driver in the "brake-by-wire" operating mode, the braking system usually includes a brake pedal feel simulation device. In the braking system, the wheel brakes can also be operated based on electronic signals without the active assistance of the vehicle driver. Such electronic signals can be output by electronic stability ...
