METHOD FOR IDENTIFYING A CHANGE IN THE OPERATING BEHAVIOR OF A CRANKSHAFT DRIVE OF A MOTOR VEHICLE

Filed:2019-07-25Pub:2021-10-14
Applicant:MAN Truck & Bus SE

The disclosure relates to a method for identifying a change in the operating behavior of a crankshaft drive of a motor vehicle. In particular, the disclosure relates to a method for identifying error states of a torsional-vibration damper in the crankshaft drive, such as a jamming or slipping of a secondary mass of the torsional-vibration damper. The crankshaft drive comprises a crankshaft, a pulse generator that rotates when the crankshaft is in operation and a fixed sensor device, which generates a rotational speed signal N as a function of the rotational speed of the pulse generator. The method comprises the following steps: detecting a current rotational speed signal N akt of the sensor device during operation of the crankshaft drive; filtering the current rotational speed signal N akt using a bandpass filter that has at least one first passband range D1 comprising a first center frequency f1; comparing the filtered current rotational speed signal N akt with a reference signal N ref stored in a memory; and identifying a change in the operating behavior of the crankshaft drive on the basis of the comparison of the filtered current rotational speed signal N akt with the reference signal N ref . The disclosure further relates to a vehicle, such as a commercial vehicle, having a control device which is configured to perform a method of this kind.
