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: A viscous shear coupling for distributing torque between front and rear axles of an all-wheel drive vehicle is provided which comprises a housing, a set of inner blades interdigitating with a set of outer blades, the inner and outer blades being axially spaced apart from each other and axially slidably mounted within the housing, a viscous liquid located within the housing, an adjusting piston within the housing which is axially displaceable so as to adjust the axial distance between adjacent inner and outer blades. The viscous shear coupling further includes a control pressure circuit for delivery of a control pressure fluid to the adjusting piston, a control valve for regulating the delivery of the control pressure fluid to the adjusting piston, and a control device (e.g., a microprocessor) which calculates a desired adjusting piston speed based on driving conditions and adjusts a valve current delivered to the control valve in order to obtain the desired adjusting piston speed.
