1. for the method controlling electromotor, including:

  • The cylinder pressure sensor in the cylinder being arranged on electromotor is used to produce for electromotorCylinder pressure signal;

    Utilize wave filter that described cylinder pressure signal is filtered, thus form the pressure filteredSignal, described wave filter has the filter coefficient produced based on engine condition;

    Described electromotor is controlled by the pressure signal filtered described in utilization;

    The cylinder pressure signal filtered is compared with threshold value;

    AndThe diagnostic signal for engine components is produced in response to described comparison.
