  • Patent number: 9175633
    Abstract: A motor vehicle has an internal combustion engine and at least one electric motor as a drive motor arranged on a common shaft. The internal combustion engine and/or the electric motor can introduce torque into a transmission downstream in the drivetrain, and a separating clutch is provided between the internal combustion engine and the electric motor. The method increases torque of the electric machine, increasing the rotational speed of the electric machine and setting slip conditions at a clutch of the downstream transmission, engaging the separating clutch to a torque between the reserve torque of the electric motor and the maximum transmissible torque, reducing the transmissible torque of the separating clutch when the rotational speed of the internal combustion engine has reached the ignition rotational speed, ending the slip conditions of the at least one clutch of the downstream transmission, ending the increase of the torque of the electric motor.

  • Patent number: 9126590
    Abstract: A method is provided for adapting the torque that can be transmitted by a clutch of a motor vehicle that has an internal combustion engine and an electric motor for driving. A pressure medium activation device is driven by an actuator and has a pressure medium link between a master cylinder and a slave cylinder for activating the clutch. An adaptation of the torque that can be transmitted by the clutch takes place in a disengaged clutch position and a change in the actuator position a given pressure of the pressure medium activation device is used to adapt the actuator position or the clutch characteristic curve.
