Embodiment Construction

[0027] As indicated above, the present invention concerns a method that enables the storage of calibration data in a rewritable memory of an automotive electronic control unit (ECU) in a very compact form, said calibration data being functionally equivalent to a full A collection of different models for the calibration data.

[0028] attached picture The first line is marked with and by no means restrictively picture shows the structure of an arbitrary model of the complete calibration data, collectively referred to as Mi, where the subscript "i" denotes any integer, here simply for example an integer selected between 1 and 5.

[0029] In other words, with picture The first line of generally picture Five different models are shown for the full calibration data, which are called M1, M2, M3, M4, and M5.

[0030] In fact, these different models include data segments that are common to each other between the models, defined as common calibration data, and described in the atta...

Abstract

The invention relates to a method for storing calibration data in a rewritable memory of an automotive electronic computer, said calibration data being functionally equivalent to a collection of different models (M1-M5) of complete calibration data, the method comprising Contains operations for recording a single copy (CALIBAS) of common calibration data (COM1-COM4) and recording specific calibration data (SP1-SP5) that offloads these common data. The present invention uses the relationships that exist between different versions (SP1-SP5) of specific data to further reduce the memory dedicated to storage by defining within these versions standard versions (T1; T2) and variants (V11; V21, V22) space, these variants unburden the data already contained in the standard versions (T1; T2).

Description

technical field [0001] The invention generally relates to the processing and storage of data. [0002] More precisely, the invention relates to a method for storing calibration data in a rewritable memory of a vehicle electronic control unit, said calibration data being functionally equivalent to a collection of different models of complete calibration data, the method comprising an operation comprising recording in the rewritable memory a set of common calibration data consisting of calibration data common to different models of complete calibration data and a set of versions of specific calibration data, Each version of specific calibration data consists of a corresponding model subset of the full calibration data and is separate from the set of common calibration data. Background technique [0003] Modern automotive electronic computers, also known to those skilled in the art as "ECU" (an acronym for "Electronic Control Unit") contain in their memory the software and da...
