Embodiment Construction

[0022] The invention relates to a braking system for a vehicle. The brake system includes in particular a hydraulic brake system. In addition to hydraulic braking systems, the braking system can also include other braking systems, in particular regenerative braking systems.

[0023] figure 1 The hydraulic brake system 1 of the embodiment shown in the figure basically comprises an actuating unit 4 , a force-pressure-converting element 2 , a hydraulic unit 8 , and wheel brakes 5 a - 5 d connected to the hydraulic unit. Furthermore, the hydraulic brake system 1 has a control unit 7 . The control unit 7 can be present as a separate control unit, but it is also conceivable that the control unit 7 is designed as a subunit of the overall brake system or of the control unit of the vehicle. Within the scope of this application, control is also to be understood as regulation.

[0024] Furthermore, the hydraulic brake system 1 has a volume adaptation unit 3 which is hydraulically con...

Abstract

The invention relates to a hydraulic brake system for a vehicle. Here, the hydraulic brake system has a force / pressure conversion element which is in hydraulic connection with at least one wheel brake cylinder of at least one wheel. Furthermore, the hydraulic brake system comprises a volume adaptation element in hydraulic connection with the at least one wheel brake and the force / pressure conversion element, and an actuating unit for actuating the force / pressure conversion element. Moreover, the actuating unit has an input element. The pressure in the at least one wheel brake cylinder, that is to say the brake pressure is set by operation of the volume adaptation unit and / or the actuating unit. To this end, it is provided that an actuating state of the input element is maintained by operation according to the invention of the actuating unit during operation of the volume adaptation unit.

Description

technical field [0001] The invention relates to a hydraulic brake system in which the pressure in at least one wheel brake cylinder of the hydraulic brake system is adjusted by means of a volume adaptation element and by means of an actuating unit. In particular, pressure regulation can be carried out individually for each wheel and in the context of antilock regulation, during a phase with an active build-up of pressure and / or after regenerative braking. The enumeration is not conclusive. Background technique [0002] EP 0292648 A2 discloses a brake system with anti-lock adjustment, which basically comprises a hydraulic brake pressure sensor actuated by the pedal, a braking device inserted in the pressure medium path between the brake pressure sensor and the wheel brakes. It consists of a dynamic pressure modulator with which the brake pressure can be varied by changing the volume of the chamber containing the hydraulic medium. As soon as the rotational behavior of the wh...
