ABSTRACT:
A method for regulating the smooth running of a multicylinder internal combustion engine. An inverse linear path model estimates a characteristic process variable from state variables of the internal combustion engine, that is to say actual values, in particular engine speed, fuel quantity, operating temperature, charging pressure, etc. A desired value is compared with the actual value that is determined from state variables of the internal combustion engine by a measuring element. The actual value shows the rotational acceleration contribution of each cylinder. The difference between the actual value and the desired value is supplied to a controller that corrects the combustion in the individual cylinders in such a way that the actual value approaches the desired value. This ensures that the regulation for the smooth running of the engine takes effect both for stationary and non-stationary operating phases of the internal combustion engine.
