Abstract: For ascertaining a future wheel brake pressure, pressure generator pressures of an external power brake pressure generator are continuously measured at measurement time intervals, the wheel brake pressure changes are ascertained therefrom, and the sum of the wheel brake pressure changes ascertained during a time period prior to the measurement is added to the last measured pressure generator pressure. The wheel brake pressure thus ascertained is considered to be the wheel brake pressure that will prevail after the time period following the measurement of the pressure generator pressure in a wheel brake.

Abstract: A method for the automated assessment, especially validation, of a simulation model which is used to simulate measured values of a quantity that is defined by one fixed parameter and one varying parameter. Multiple simulation values are determined for the quantity with the aid of the simulation model. Multiple associated reference values are determined for the quantity. For each of multiple values of the varying parameter, in each case a model-form error is determined as deviation between the simulation value with respect to this value of the varying parameter and the reference value with respect to this value of the varying parameter. On the basis of the model-form errors for the multiple values of the varying parameter, a function of the model-form error is determined depending on the varying parameter and used for the assessment, especially validation, of the simulation model.
