Abstract
A method for the calibration or diagnosis of a motor vehicle brake system having a cyclically operated pump. At least one parameter (U), representing the electromotor force of the reference pump, is repeatedly ascertained during operation of a reference pump under defined guidelines. A statistical characteristic variable (U) is derived from the values of parameter (U) ascertained for the reference pump. Parameter (U) is ascertained under a corresponding guideline during operation of an operating pump. Corresponding statistical characteristic variable (U) is derived from the values of parameter (U) ascertained for the operating pump. At least one ratio number is calculated as a measure of the deviation of the operating behavior of the operating pump from the operating behavior of the reference pump from the characteristic variable (U) calculated for the reference pump and the characteristic variable (U) calculated for the operating pump.
