  • Publication number: 20040112158
    Abstract: A power transmission for a motor vehicle. The transmission includes a plurality of transmission ratio steps defined by pairs of gear carried on parallel shafts, and final output mechanisms for engaging desired transmission ratio steps. The final output mechanisms are operable for controlling the engagement of respective transmission ratio steps to minimize tractive force interruption by allowing rapid gear changes to be effected to reduce the times between shifts of gears. By sensing accelerator pedal position and vehicle speed a new transmission ratio step to be subsequently engaged can be pre-selected while an engaged gear remains engaged.

  • Publication number: 20040025612
    Abstract: A transmission including a drive shaft that can be connected with a drive motor. The transmission has at least two input shafts that are part of respective separate, parallel transmission paths that each include a plurality of gear trains defining respective transmission ratios. At least one clutch is provided to enable a transmission step to be shifted with reduced tractive force interruption during a shift between different gears.

  • Patent number: 6679361
    Abstract: A motor vehicle power train with an engine, a transmission and a clutch includes a means to operate the transmission and/or clutch automatically through at least one electric actuator motor. The electric actuator motor, which acts on an input element of the transmission and/or clutch, comprises a brushless direct current motor.

  • Patent number: 6443276
    Abstract: The power train of a motor vehicle has an automated transmission and/or an automated clutch, at least one control unit and at least one actor receiving signals from the control unit and serving to control the operation of the automated constituent or constituents of the power train. A reestablishable connection can be interrupted in the event of a malfunctioning of the power train, such as exhaustion of the supply of electrical energy, defectiveness of the actor and/or defectiveness of the automated constituent or constituents and/or defectiveness of the motion transmitting connection or connections between the actor and the automated constituent or constituents. This renders it possible to set the transmission in neutral or into another gear and/or to select the condition of the clutch in such a way that the vehicle can advance to a selected destination under it own power or that it can be towed to such destination.

  • Publication number: 20010008199
    Abstract: The power train of a motor vehicle has an automated transmission and/or an automated clutch, at least one control unit and at least one actor receiving signals from the control unit and serving to control the operation of the automated constituent or constituents of the power train. A preferably reestablishable connection can be interrupted in the event of a malfunctioning of the power train, such as exhaustion of the supply of electrical energy, defectiveness of the actor and/or defectiveness of the automated constituent or constituents and/or defectiveness of the motion transmitting connection or connections between the actor and the automated constituent or constituents. This renders it possible to set the transmission in neutral or into another gear and/or to select the condition of the clutch in such a way that the vehicle can advance to a selected destination under it own power or that it can be towed to such destination.
