    CRANK VELOCITY DRIVELINE FILTERING FOR CONSECUTIVE MISFIRE DETECTION

    CRANK VELOCITY DRIVELINE FILTERING FOR CONSECUTIVE MISFIRE DETECTION

    Freier Zugriff

    A misfire detection system and method for a vehicle utilize a controller to obtain a crankshaft speed signal indicative of a rotational speed of an engine crankshaft connected to a device that mitigates vibrational disturbances at the crankshaft caused by misfires of the engine, detect that a first firing event of the engine is a first misfire based on the crankshaft speed signal, monitor a vibrational response of the crankshaft, detect that a consecutive second firing event of the engine is a second misfire based on a first modified crankshaft speed signal and the first set of thresholds, and in response to detecting the second misfire, reset the monitoring of the vibrational response of the crankshaft including modifying the amplitude of the crankshaft speed signal to obtain a second modified crankshaft speed signal and comparing the second modified crankshaft speed signal to a set of thresholds.
