Axel Prenger-Berninghoff has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 10427667
    Abstract: The invention concerns a method for automatically controlling a motor vehicle (10) for switching from a “normal” mode to a “freewheel” mode, the vehicle (10) comprising an engine (12) capable of providing engine torque to drive wheels (14) via an automatically controlled clutch device (18) that comprises a drive shaft (15) and a driven shaft (16). A transition step (E1) is interposed chronologically between the “normal” mode and the “freewheel mode” during which the engine (12) is automatically controlled in such a way that the driven shaft (16) and the drive shaft (15) turn at the same speed without transmitting torque to the drive wheels (14).

  • Patent number: 8701517
    Abstract: A method for gear shifting a dual clutch transmission from an initial gear into a target gear and a respective dual clutch transmission are described. The dual clutch transmission comprises a first partial transmission and a second partial transmission. When shifting from an initial gear into a target gear which are both allocated to the first partial transmission, gears are shifted at least for a short time period into the support gear prior to gear shifting from the support gear into the target gear. A process of an uninterrupted reduction of the transmitted clutch torque down to zero at a first clutch allocated to the initial gear is started prior to starting a process of closing the second clutch allocated to the support gear.
