Abstract

Device and method for determining a wheel braking pressure and/or an admission pressure in a braking system in which pressure medium is introduced from a reservoir for the pressure medium having an admission pressure into a wheel brake through at least one shutoff device for inlet and/or outlet and/or passage of a pressure medium, it being possible to remove pressure medium from the wheel brake through at least one means delivering the pressure medium. In so doing, a pressure quantity representing the admission pressure is estimated, at least one operating state of at least one actuator in the braking system is detected and the wheel braking pressure is estimated as a function of the estimated admission pressure and the detected operating states.
