Abstract: 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.

Abstract: A hybrid vehicle drive control system selectively switches from an electric drive (EV) mode in which a first clutch is released and a second clutch is engaged, and a hybrid drive (HEV) mode in which both clutches are engaged. A slip control of the second clutch is executed when the first clutch is being connected to start the engine during switching from EV mode to HEV mode by controlling a torque transfer capacity of the second clutch to a required drive force, and by simultaneously increasing a motor/generator torque by an amount corresponding to a torque required to start the engine while maintaining a slipping state of the second clutch until connection of the first clutch is completed. Thus, a loss of torque is not felt by the driver and the shock is small when the engine is started during switching from EV mode to HEV mode.
