Embodiment Construction

[0031] figure 1 Two different partitions of the non-volatile memory of the control unit for the two vehicle variables V, V′ are schematically shown.

[0032] The memory is partitioned according to the corresponding vehicle variant. In this case, the combined characteristic curve (hereinafter used synonymously for characteristic curve, combined characteristic curve and similar control variables) can have different dimensions (for example the number of grid points) for different vehicle variants. Then, different combined characteristic curves for different variables require different sizes of storage space.

[0033] This nonvolatile memory is, for example, a flash memory. The non-volatile memory is preferably divided into different areas.

[0034] Functional software C is stored in an area. Parameters P1 , . . . , P5 or P1 ′, . . . , P5 ′ are stored in a further area. There, too, characteristic curves or combined characteristic curves or other types of control variables can...

Abstract

The present invention relates to a method and an arrangement for managing a non-volatile memory of a control device. Method for managing a non-volatile memory of a control device, characterized in that - read information about adjustment variables (M1, M2, M1', M2') from a static area (101) of said non-volatile memory First information (PM1, PM2, PM1', PM2'), - determine the storage location of the adjusted variable, - read from the variable area (102) of the non-volatile memory on the basis of the storage location information on the dimensions of the adjusted variable, - determine the type of the adjusted variable, - determine at least one grid point and / or at least one value of the adjusted variable based on the information about the type, dimension and storage location of the adjusted variable at least one storage location of the control variable, - read at least one grid point and / or at least one value of the adjustment variable according to the corresponding storage location of the grid point or the value.

Description

technical field [0001] The present invention relates to a method and an arrangement for managing a non-volatile memory of a control device. Background technique [0002] Functions are implemented by functional software on control units, in particular those used in motor vehicles. Motor vehicles are equipped with different components depending on the embodiment. For example, different motorization or transmission types are available as vehicle variants. In order to adapt the functional software to the various vehicle variants, a plurality of control variables (eg parameters, characteristic curves, combined characteristic curves (Kennfeld)) are provided which form what are known as data sets. [0003] The control variables are parameterized for different vehicle variables. In this case, existing parameters, characteristic curves or combined characteristic curves are implemented with different values ​​for the individual vehicle variables. [0004] A non-volatile memory, fo...
