    摘要: A method for determining a wear value of a transmission element between a crankshaft and a camshaft of a reciprocating piston internal combustion engine, in particular a timing chain or toothed belt, is provided. The camshaft is driven by the transmission element via a drive part, for example a camshaft gearwheel. In each case, at least one measurement value for the phase position of the drive part relative to the crankshaft is determined at time intervals during which the crankshaft drives the camshaft, and the wear value is determined from the difference between the measurement values.

    摘要: In a method for operating a drive train for a motor vehicle, a torque is produced by means of an internal combustion engine as a function of an available torque set value signal and transmitted to drive wheels by means of a clutch. With the help of an electric motor, a closing force is applied, with which the clutch is held in a closed position against a restoring force. The electric motor is energized in such a way that a high current is used in the case of a high torque and a lower current is used in the case of a lower torque. The thermal load of the electric motor is determined and a load signal corresponding to the thermal load is produced. The load signal is compared with a load limit signal assigned to a permissible load range. If the load signal deviates from the load-limit signal, the torque of the internal combustion engine is limited.
