Apparatus and method for determining the pinpoint capability of possible errors of one or more components

摘要

An apparatus (1) for determining whether a possible error (Fl1, F12, F13, F21, F22, F31, F41) of one or more components (K1, K2, K3, K4) is based on results of predetermined diagnostic possibilities (DM1, DM2 , DM3), comprises: (a) a memory device (4), which is configured to determine parameters for each combination of a possible error (Fl1, F12, F13, F21, F22, F31, F41) of one of the components ( K1, K2, K3, K4) and a possible diagnosis result provide a measure of whether the respective error (Fll, F12, F13, F21, F22, F31, F41) is possible, if the respective diagnosis result is present, in a matrix (20 ), wherein the rows of the matrix (20) are each assigned to one of the possible diagnostic results and wherein the columns of the matrix (20) are each assigned to one of the possible errors (Fll, F12, F13, F21, F22, F31, F41) ; (B) a selection device (6), which is adapted to select at least two rows of the matrix (20), which for a diagnostic result, which compatible with an error to be identified (Fll, F12, F13, F21, F22, F31, F41) is, contain a parameter that is greater than a predetermined first limit; (c) a computing device (8) configured to calculate a result vector by multiplying the selected rows of the matrix (20) element by element; and (d) determining means (10) arranged to determine whether the result vector contains at least one element not less than a predetermined second threshold, the elements of the result vector less than the predetermined second threshold not are greater than a predetermined third limit.
