Brake system for a vehicle and method for operating a brake system of a vehicle

摘要

A brake system for a vehicle includes: a main brake cylinder with a floating piston able to be shifted at least partially into the main brake cylinder, and a brake medium storage device into which a specified storage volume of a brake medium is able to be transferred without counterpressure, the brake medium storage device being hydraulically connected via an electrically controllable first valve to the main brake cylinder in such a way that, in response to a shifting of the floating piston partially into the main brake cylinder by a shift travel that is below a shift travel limit corresponding to the storage volume, a brake medium volume less than the specified storage volume is transferred without counterpressure from the main brake cylinder into the brake medium storage device.

1. A brake system for a vehicle, comprising:
a main brake cylinder; a main brake cylinder floating piston configured to be selectively shifted at least partially into the main brake cylinder; a brake medium storage device, wherein a specified storage volume of a brake medium is able to be transferred into the brake medium storage device; an electrically controllable first valve via which the brake medium storage device is hydraulically connected to the main brake cylinder in such a way that, in response to the shifting of the main brake cylinder floating piston partially into the main brake cylinder by a shift travel less than a shift travel limit corresponding to the specified storage volume, a brake medium volume less than the specified storage volume is transferred from the main brake cylinder via the first valve in at least partially opened state into the brake medium storage device; and a control device configured to control the brake system (i) into a first mode by controlling the first valve into the at least partially opened state, wherein in the first mode of the brake system a pressure increase in the main brake cylinder is prevented by shifting the main brake cylinder floating piston partially into the main brake cylinder by the shift travel that is below the shift travel limit, and (ii) into a second mode by controlling the first valve into a closed state, wherein in the second mode of the brake system, in response to a shifting of the main brake cylinder floating piston partially into the main brake cylinder by the shift travel that is below the shift travel limit, a pressure in the main brake cylinder increases.
