Abstract

The invention relates to a brake system for a motor vehicle and a method for its operation, said brake system having a brake master cylinder actuatable by means of a brake pedal, said brake master cylinder having at least one brake circuits of the hydraulically operable wheel brakes can be separately connected; a hydraulically operable pedal travel simulator connected or connectable to said brake master cylinder; an electrically controllable pressure supply device, said pressure supply device and The brake circuit can be connected separately; electronic control and regulation unit, wherein, when the brake pedal is actuated, the brake circuit is loaded with the pressure of the pressure supply device in the first operating mode and in the second The pressure of the brake master cylinder is loaded in the second operating mode, wherein the operating stroke of the brake pedal is electronically controlled during the operation of the brake pedal when changing from the second operating mode to the first operating mode Controlling or modulating adjustment.

Description

technical field [0001] The invention relates to a method for operating a brake system of a motor vehicle and to a brake system. Background technique [0002] In motor vehicle technology, "brake-by-wire" braking systems are becoming more and more popular. Brake systems of this type usually comprise, in addition to a brake master cylinder which can be operated by the vehicle driver, an electrically controllable pressure supply device by means of which the wheel brakes or brakes are applied in the "brake-by-wire" operating mode. operation of the master cylinder. In order to convey a pleasant pedal feel to the driver of the vehicle in the "brake-by-wire" operating mode, the brake system usually includes a brake pedal feel simulator. In the braking system, the wheel brakes can also be actuated on the basis of electronic signals without active assistance from the vehicle driver. Such an electronic signal can be output, for example, by an electronic stability program or a distan...
