Abstract
Method for combustion engine control comprising an engine, at least one sensor and at least one engine control unit (200) arranged to control the engine (100) by the use of real time sensor data S(k) characterized in that a prior (P1(k, j; z), P2(k; X, Y) is used to derive at least one combustion parameter estimate (X(k)) and/or at least one combustion parameter measurement (Y(k)) from the real lime sensor data (S(k)) and that the at least one combustion parameter estimate (X(k)) and/or the at least one combustion parameter measurement (Y(k)) is used in performing said engine control.

A method for control of a combustion engine comprising an engine, at least one sensor and at least one engine control unit (200) arranged to control the engine (100) by the use of real time sensor data S(k), comprising the steps of using a prior (P1(k,j;z), to derive at least one combustion parameter measurement (y(k,j)) from the real time sensor data (S(k)), and using the at least one combustion parameter measurement (y(k,j)) in performing said engine control, wherein within a single combustion cycle (k), the prior (P1(k,j;z)) is used in order to select a combustion parameter candidate (z(k,j,n)) from a set of candidates (z(k,j,1) . . . z(k,j,N)) as the measurement (y(k,j)) of the combustion parameter (v(k,j)).
