Abstract
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.
