Abstract

A correction method in which characteristic curves and/or correction values are produced, by way of which the drive current for one or more electrically activated hydraulic values operated in an analog fashion is measured during a pressure regulation in such a way that, during the operation of an anti-lock regulation, one or a respective characteristic curve is first prescribed and then the prescribed characteristic curve is corrected, particularly in a learning process, wherein, after a pressure build-up phase, the current pressure model value (Pmod) is compared to and/or analyzed using a model locking pressure level (Pmax).
