Abstract:
A method of filtering at least one set of data, the method comprising:determining a subset of Q1 data elements of a first set of L1 data elements, wherein Q1 is at least two, wherein each of the subset of Q1 data elements is greater than at most a first predetermined number of the first set of L1 data elements and greater than or equal to at least a second predetermined number of the first set of L1 data elements other than itself;determining a first filtered value for the first set of L1 data elements based upon the subset of Q1 data elements;determining a subset of Q2 data elements of a second set of L2 data elements, wherein each of the subset of Q2 data elements is greater than at most a third predetermined number of the second set of L2 data elements and greater than or equal to at least a fourth predetermined number of the second set of L2 data elements other than itself;determining a second filtered value for the second set of L2 data elements based upon the subset of Q2 data elements;detecting a misfire condition based upon the first filtered value; andwherein L2 differs from L1.
