Method for identifying interruptions in internal combustion engine based on run disturbance signal calculated from speed fluctuations, involves carrying out dynamic compensation of run disturbance signal by compensation value

摘要

The method involves carrying out a dynamic compensation of the run disturbance signal by a compensation value. A quantity of the differentials of segment time is filtered with a low-pass filter (56) for calculating the compensation value. The maximum value for all differentials of segment time is searched, and is exchanged by a suitable value before the calculation of the filter value of the maximum value. An independent claim is also included for an arrangement for identifying interruptions in an internal combustion engine.
