    摘要: A method controlling a clutch arrangement that serves, in a powertrain of a motor vehicle, for the transmission of a torque from an input element to an output element. Starting from an activated state of the clutch arrangement, a respective estimated torque value is calculated in repeating calculation cycles. A torque build-up value is calculated in dependence on at least one speed difference value. A torque reduction value is calculated in dependence on at least the last calculated estimated torque value. The estimated torque value is re-calculated on the basis of the last calculated estimated torque value by up integration of the calculated torque build-up value and down integration of the calculated torque reduction value. The recalculated estimated torque value is compared with a torque threshold value. The clutch arrangement is deactivated when the recalculated estimated torque value is below the torque threshold value.

    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.

    摘要: A hybrid vehicle is driven by one or both of an engine and a drive motor. The engine is started by a power generating motor, and power generated by the engine is supplied to a battery. An engine-power transmission path is provided with a coupling for being shifted to a connection state of transmitting engine power to drive wheels and a disconnection state of cutting off the transmission. In connecting the coupling while the drive motor is driven and transmitting engine torque, a revolution speed of the power generating motor is controlled based on that of the drive motor. After a revolution speed of an input-side shaft of the coupling is synchronized with that of an output-side shaft, the coupling is connected. After the coupling is connected, torque of the drive motor and engine is controlled based on required torque of the vehicle.
