DIAGNOSTIC METHOD FOR DETECTING DISCONTINUITIES IN CONTINUOUS MEASUREMENT VARIABLE AND CONTROLLER FOR CARRYING OUT METHOD

A diagnostic method for detecting discontinuities in a continuous measurement variable, comprising: capturing an input signal (I), testing a discontinuity criterion (BD) on the basis of the input signal (I), when the discontinuity criterion (BD) is met, enabling a diagnosis, comprising: capturing th...

Beschreibung
Zusammenfassung:	A diagnostic method for detecting discontinuities in a continuous measurement variable, comprising: capturing an input signal (I), testing a discontinuity criterion (BD) on the basis of the input signal (I), when the discontinuity criterion (BD) is met, enabling a diagnosis, comprising: capturing the input signal (I) within a transit time (T) starting from a point in time (t0), defining the inputsignal (l0) at the point in time t0 of the transit time (T) as a reference value (R) starting from an initial reference position (R0), determining the profile of a relative diagnostic variable (IR) byshifting the profile of the input signal (I) by the reference difference (RD) between the initial reference position (R0) and the reference value (R), wherein the profile of the relative diagnostic variable (IR) is increased by the reference difference (RD) if the reference value (l0; R) is lower than the initial reference value (R0), and is decreased by the reference difference (RD) if the reference value (l0; R) is high
