1. A correction method comprising the steps of: generating, by a processor, at least one of actuation characteristic curves and correction values; using, by the processor, the at least one of actuation characteristic curves and correction values during a pressure control process to dimension an actuation current for one or more electrically actuated hydraulic valves which are operated in analogue fashion, predefining, by the processor, one actuation characteristic curve during operation of an anti-lock brake system; correcting, by the processor, the predefined actuation characteristic curve in the course of a learning process, and computing, by the processor, a difference pressure between a current pressure model value for the controlled wheel and a model locking-pressure level during a wheel pressure control process, wherein at least one of the difference pressure and the model locking-pressure level are compared to a respective threshold, and if the at least one of the difference pressure and the model locking-pressure level exceed the respective threshold, the predefined actuation characteristic curve is not corrected.
