For ascertaining at least one variable regarding a state of a brake fluid in a brake system of a vehicle, an evaluation unit is configured to determine the at least one variable by taking into account at least one pair of values of a provided or ascertained volume flow variable regarding a volume flow of at least a portion of the brake fluid through a flow resistance in the brake system and a provided or ascertained associated pressure drop variable regarding a pressure drop at the flow resistance through which the volume flow flows. For the at least one pair of values taken into account, a volume flow variable lies within a first specified limited value range and the pressure drop variable lies within a second specified limited value range.

Device and method for ascertaining at least one variable regarding a state of a brake fluid in a brake system of a vehicle

The present invention relates to a braking device and to a braking system, each having a master brake cylinder () having at least one first pressure chamber () that is subdivided or is able to be subdivided at least into a first partial volume () and a second partial volume (), which are hydraulically connectable or connected to a brake fluid reservoir (), a first brake circuit () being hydraulically connectable or connected to the first partial volume (), and having a valve device () that is mechanically designed in such a way that a pressure buildup up to a mechanically specified limit pressure may be brought about in the second partial volume (), brake fluid being transferable at least into the first brake circuit () via at least one subcomponent () of the valve device (), and an exceeding of the limit pressure in the second partial volume () being prevented.

Braking device for a braking system of a vehicle and braking system for a vehicle

A brake system for a vehicle, including: a master brake cylinder having a first chamber, a rod piston, which, together with at least one first hydraulically active surface area, bounds the first chamber, a second chamber and a floating piston; the rod piston being configured with or couplable to a second hydraulically active surface area; the second hydraulically active surface area bounding an auxiliary chamber of the master brake cylinder or of another brake cylinder, and the auxiliary chamber being attached to an accumulator chamber and/or to the hydraulic reservoir via a first nonreturn valve and a restrictor that is configured in a further fluid line.
