  • 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.

  • Patent number: 8851216
    Abstract: A component housing in a motor-vehicle drive train is sealed by pressurization of the housing interior. The component is a hybrid module (1) comprising at least one electric machine provided between the combustion engine (VM) and the gearing (G) of the motor-vehicle drive train. The pressurization is achieved by a rotating component (R, RA, M, F) of the hybrid module. The rotating component is designed in a manner similar to an impeller of a centrifugal pump. Therefore, rotation of the component builds up a positive pressure (P) on the radially outer region of the rotating component in the region of the housing (GE) in the interior of the hybrid module.

  • Patent number: 8676424
    Abstract: A drive system includes at least two drive devices, at least one of which is electric, that drive at least two drive axles, a power electronics system, an energy storage arrangement, and a control device. The control device includes a drive control module for providing a recuperation limiting value for each electric drive, a recuperation control module for combining the recuperation limiting values to form a maximum recuperation total limiting value, and a brake control module for providing a total braking torque requested by a driver or assistance system, such that it derives a recuperation total torque that is less than the recuperation total limiting value and also derives recuperation partial torques for each electric drive. In the case of a total braking torque that is greater than the recuperation total limiting value, the brake control module generates a hydraulic brake pressure and transmits it to the brake system.

  • Patent number: 8360183
    Abstract: A vehicle has an internal combustion engine, an electric drive device and a transmission with two component transmissions that can be selected simultaneously. Torque can be transmitted from the electric drive device and/or the internal combustion engine to at least one axle of the vehicle, and a torque can be transmitted from the axle to the electric drive device and/or the internal combustion engine. The internal combustion engine is adjusted from a deactivated state to an energized state. Torque is transmitted to the internal combustion engine by the axle and/or the electric drive device via one of two shifting elements to increase rotational speed of the internal combustion engine. The internal combustion engine is adjusted to a target rotational speed via one of the shifting elements. The connection between the internal combustion engine and the axle is produced via one of the shifting elements upon reaching the target rotational speed.

  • Patent number: 8047959
    Abstract: A method is provided for starting a piston engine of a hybrid drive in an electric travel state. The hybrid drive includes at least the piston engine, an electric motor, a transmission, and a clutch situated between the piston engine and the electric motor. A converter lockup clutch, which is switchable into a slip state, is also provided. A slip is set at the converter lockup clutch, and a speed of the electric motor is then increased. The speed and the torque either do not change or only change in a predefined range at the output side of the converter lockup clutch. The clutch is closed to transmit a torque pulse, so that a first top dead center of the piston of the piston engine may be overcome. A predefined slip is then set at the clutch.
