  • Patent number: 10654464
    Abstract: A method for compensation of a support torque at a combustion engine and transmission which provide an overlay of combustion engine and electric machine. The combustion engine, the electric machine, and a transmission gearset are connected with each other via a planetary gearset, which is positioned in front of a downstream transmission gearset. The invention concerns a transmission gearset of a three-shaft transmission, each with a transmission input shaft for the electric machine, and for the combustion engine, and an output shaft. For the connection or disconnection of the transmission input shaft of the electric machine while driving, the electric machine is used for the synchronization of the input shaft of the electric machine, and the created support torque at the combustion engine is determined, based on this support torque, to match a combustion engine torque and thus to compensate the support torque.

  • Patent number: 10648555
    Abstract: A method of controlling the gear shifting of an automatic range-change transmission, which is arranged between a drive engine and a final drive in a drive train of a motor vehicle and includes at least one multi-stage main transmission, a two-stage front-mounted group upstream of the main transmission, and a transmission brake. The main transmission can be shifted, via unsynchronized clutches, and the front-mounted group can be shifted, via synchronized clutches. Upon upshifting in the range-change transmission including at least one change of a transmission ratio stage of the front-mounted group, synchronization of the front-mounted group is effected via actuation of the synchronized clutch of the front-mounted group and supportingly via at least intermittently parallel actuation of the transmission brake.

    Abstract: A method for detecting non-approved parts in a vehicle includes generating a plurality of component identifiers (IDs) for a plurality of components, wherein each component ID identifies a unique component of the plurality of components. The component IDs are stored to a decentralized database. A vehicle identifier (ID) that uniquely identifies a vehicle is generated and stored to the decentralized database. Component IDs associated with components of the vehicle that are stored in the decentralized data base are associated with the vehicle ID. The method includes subsequently, determining that a component of the vehicle has been replaced with a replacement component and searching the decentralized database for a component ID associated with the replacement component.
