Abstract: The invention relates to an electrically actuatable assembly of a motor vehicle having at least one component comprising a non-volatile memory. The component has base functionality characteristic for the component and required for the operation of the assembly. The memory comprises a memory region not utilized for realizing the base functionality of the component, in said memory region is stored a characteristic value that identifies the assembly with a predetermined probability. Furthermore, the characteristic value can be read out from the memory region of the component. Finally, the invention describes a method for identifying such an electrically actuatable assembly.

Abstract: An energy supply system for electrical actuator of a motor vehicle having a engine and battery includes a generator adapted to be driven by the vehicle engine to provide electrical energy to the electric actuator and vehicle battery. A control unit sets an input power provided to the generator by the vehicle engine and is configured to set the output voltage of the generator based on a power request associated with the electric actuator. A method for supplying electrical energy to a vehicle subsystem may be performed using an energy supply system as disclosed.

Abstract: An actuator comprises an electric actuating motor, a transmission mechanism and an actuating element, the actuating motor being a DC motor which comprises a first part having permanent magnets and a second part having windings and pole teeth. In order to be able to hold the actuator in any desired, adopted position without any additional apparatuses, the first part (30) has alternately first zones having a low magnetic field strength (31) and second zones having a high field strength (32) over its circumference, the circumferential angle (33) of the second zones (32) being equal to the circumferential angle (38) of the pole teeth (37) of the second part (35), the number of pole teeth (37) being selected such that all of the second zones (32) are always passed at the same time by a pole tooth (37), with the result that, in the event of a rotation in the state in which there is no current flowing, a pulsating torque is exerted between the first part (30) and the second part (35).

Abstract: In a power-split transmission for driving a first and a second axle of a motor vehicle, in the case of which transmission are located a first and a second output shaft (3, 4) and a friction clutch (12), the latter is intended to transmit a controllable torque. For this purpose, (a) for the action of pressure upon the pressure plate (29), there are provided two rotationally uncoupled ring parts (31, 32) which are coaxial to the friction clutch and at least one of which possesses ramps rising in the circumferential direction, (b) the two ring parts (31, 32) are supported in the axial direction and each possess a ramp lever (35, 36), the free end (37, 38) of which cooperates with a control unit (11) which moves the ramp levers in opposite directions, and (c) the control unit (11) having a rotatable control disk (40) with two slots, and the drive means being an electric geared motor.
