METHOD FOR DETERMINING A DEFECT STATE OF A DRIVE TRAIN OF A VEHICLE, MONITORING UNIT AND VEHICLE

A method determines a defect state of a drive train of a vehicle having a drive axle with a drive wheel and a reference axle with a reference wheel. A drive torque generated by a drive is transferrable to an underlying surface by the drive train via the drive wheel and cannot be transferred to the u...

Zusammenfassung:	A method determines a defect state of a drive train of a vehicle having a drive axle with a drive wheel and a reference axle with a reference wheel. A drive torque generated by a drive is transferrable to an underlying surface by the drive train via the drive wheel and cannot be transferred to the underlying surface via the reference wheel of the reference axle. The method includes: reading-in a drive variable which is dependent on a motor revolution rate of the drive; reading-in a reference variable which is dependent on a reference wheel revolution rate of the reference wheel; determining whether there is a deviation between the read-in drive and the read-in reference variables to determine whether the reference wheel revolution rate is related to the motor revolution rate of the drive. If there is a deviation, a defect state of the drive train is concluded.
