Embodiment Construction

[0029] figure 1 A functional unit 10 is shown, which can be a motor vehicle, for example. A processor device 11 , an operating device 12 and a communication device 13 are shown in the functional unit, each of which can be provided, for example, in the functional unit 10 . The functional unit 10 can have at least one preinstalled function 14 and / or can provide or enable at least one subsequently installable function 15 . The functions 14 , 15 may respectively be program code-based functions or software functions that can be implemented or provided by the processor means 11 . For this purpose, the processor device 11 may comprise at least one microprocessor and / or at least one microcontroller. The processor means 11 can be realized eg by a controller or by a combination of several controllers. A user of the functional unit 10 can use the functions 14 , 15 if they are activated (that is to say actually installed in the functional unit 10 and also switched on / triggered). For e...

Abstract

The invention relates to a method for determining the function presence (16) of a functional unit (10), in which at least one installed function (14) and / or At least one function (15) can subsequently be installed and thus correspondingly activated, wherein the function presence (16) of the functional unit (10) represents the set of functions actually activated. According to the invention, in the method, the current functional presence (16) of the functional unit (10) is ascertained by the control device (18) of the functional unit (10) and actual presence data (26) are generated for the current functional presence (16) , the actual presence data describes the ascertained functional presence (16), and the application related to the supposed functional presence (16') is queried in the external server device (19) from a predetermined blockchain credit account (24). Presence data (25) are present, and in the event that the ascertained actual presence data (26) differs from the supposed presence data (25), predetermined enforcement measures (27) are triggered to prescribe the supposed functional presence (16') .

Description

technical field [0001] The invention relates to a method for determining or specifying the presence of functions of activated functions in a functional unit. In the functional unit, at least one function is deactivatable and / or retrofittable, so that the presence of activated functions of the functional unit can be changed. The invention also includes functional units having a changeable functional presence. Background technique [0002] Such a functional unit is known, for example, from DE 10 2009 025 585 A1, in which a motor vehicle is described as the functional unit. In order to enable a function, payment for this function usually has to be made at the manufacturer of the functional unit or at the supplier of the function. This is called a feature on demand. However, since the functions may be pre-installed and only need to be enabled, for example, by means of an activation code, users are always trying to bypass the protection of the pre-installed functions in the fu...
