The invention relates to a hybrid drive unit, in which for the most optimum possible synergetic use of the combustion engine drive and electromotive drive, a multi-speed clutch- and gear assembly is provided, in which both the combustion engine drive power and also the electromotive drive power is introduced into an input member of the clutch- and gear assembly. Hereby, numerous drive variants are made possible, which allow the drive machines to cooperate with each other according to requirements. The invention additionally relates to the method by which such a drive unit is operated.

Hybrid drive unit and method for its operation

The invention relates to a vehicle having a drive train, which comprises at least one first engine and a wheel, wherein a torque can be transmitted from the first engine to the wheel by the drive train, and wherein at least one first unit of the drive train is connected to an interface, by which rapid and simple replaceability of said unit is possible, wherein the interface is designed to be connected to a second unit, which is different from the first unit, wherein both units are designed to store electricity, to convert chemically bound energy into energy of rotation and/or to convert electricity into energy of rotation and/or to convert rotation energy of rotation into electricity.

Vehicle having drive train

A position sensor, a position sensor arrangement and a method of operating the position sensor and position sensor arrangement is described, working on the basis of magnetic field sensing sensors maximizing reliability against defects and external interference signals and providing redundancy, in particular for shift-by-wire systems in automobiles. The invention includes various aspects and preferred embodiments including individual sensors that can either only measure the direction of the magnetic field or in addition to that the absolute value of the magnetic field. The specific embodiments depend on the desired diagnostic options, redundancy and compensation capabilities both as to interfering magnetic fields and sensor failures or non-plausible output signals of individual sensors. An evaluation unit can be provided for compensating measurement deviations. Goals are to make the position sensor compact in size, cost effective, maximize reliability against defects and external interference signals, have diagnostic ability and provide redundancy.
