Abstract: A configuration of a pair of inductor coils within a local measuring range which can comprise a position range or an angle range. For the coil configuration, a nominal distance to a damping part is predefined which comprises an eddy current damping part which covers the coils, to a certain degree. In the evaluation circuit, the coils are connected to a capacitor, forming an oscillator part, whose inductance and capacitance determine a resonant frequency. The characteristic curve, oscillator frequency as a function of the position or the angle is linear. The rectangular inductors of the pair of coils overlap within the measuring range. The linear characteristic curves have a common point of rotation, outside of the measuring range, which is independent from interferences by the measuring configuration.

The drive train comprising a hybrid drive with an internal combustion engine and an electric motor, a transmission arranged between the hybrid drive and a drive output, and a clutch arranged between the internal combustion engine and the electric motor.

The clutch is controlled to partially engage to start the combustion engine and then it is completely disengaged before reaching a synchronous speed between the combustion engine and the electric motor.

Abstract: A method and device for actuating a shifting arrangement with electric actuators of a transmission control of a motor vehicle. The method includes determining a total current of the shifting arrangement available at a point in time, detecting shift requests of shift elements and compared these with the total available current. Shift requests are then tested according to preset priorities and the sequentially performed according to the priority test. The method avoids exceeding a preset allowed current load, when the requested shifts would exceed the total available current. If the total available current would not be exceeded by the requested shifts, the requests are carried out. A device is also provided in the shifting arrangement which has control and detection mechanisms that monitor current and control the current flow.
