Abstract

A method for determining a variable representing a hydraulic pressure drop across a valve of a brake circuit, in which a control pulse, designed such that abrupt braking pressure changes are suppressed, is applied to the valve, and in which the hydraulic pressure drop across the valve is determined from the knowledge of the control pulse.
