and communication methods from the ASAP2 description file, and are Via the ASAP1b interface the standard connection of the control units. ASAP2 Lib is a powerful and easy-to-use function library, which you can use for reading and writing standardized ECU description files in ASAP2 format for your . The ASAP2 Tool-Set consists of 6 programs for creating, checking, updating, merging, A2L files that are not standard-conformant can also be read-in using the.

Specifies that a tunable axis with a dynamic number of axis points does not compact or expand in memory when removing or inserting axis points. For an overview, see Data Objects Simulink. This model shows ASAP2 data export. Each finds data elements and properties within the description format that they need for their work. Without standardization, the OEM or Tier 1 would be required to maintain several data description files in parallel or else continuously converting the files between different formats to standarrd that everyone in the development process used the right format.

The following table indicates the Simulink object properties that have replaced the ASAP2 object properties of the previous release:. All Examples Functions Blocks.


ECU calibration with the ASAP2Library and ASAP2Demo

This variable can be a scalar or an array. The description contains information about data types, dimensions, record layouts and memory locations of ECU variables.

Secondary keywords may actually span across several more levels. Axis shared by various tables. The standard is used furthermore in other tools in the MCD area, such as data loggers, diagnostic tools, rapid control prototyping systems and automated calibration and testing systems.

You can use the Model Data Editor and built-in Simulink data objects to provide the information.

This number is fixed and not stored in memory. Verbal conversion tables are described by stanadrd of input-values and output-strings.

The a2l-file consists of four structural levels:. As the control software grew in complexity, the development of the software was split up into several groups of engineers function developers, software developers, calibration engineers, vehicle test engineers, etc. For example, in an n-D Lookup Table block with 2 dimensions, the structure must contain only three fields.


Choose a web site to get translated content where available and stancard local events and offers. Software sources do not have to be shared any longer to allow other parties to tune parameters or change the list of measurable. Supported conversion methods are: By default, the software generates ASAP2 version 1.

Such a description of calibration and measurement variables can easily extend to several thousand entries per ECU.


The fourth and lower levels of an a2l-file consist of secondary keywords. Each module represents one ECU.

The A2ML block only describes the syntax of communication parameters. The calibration of parameters is an essential part of ECU software development. Select the China site in Chinese or English for best site performance. Keywords can contain parameters and other keywords. Definition of structured data types similar to the “typedef” command in C.

For information about data objects, see Data Objects Simulink. This bus object describes the record layout for the stxndard characteristic. This is no longer a limitation. The variety of tools and description formats would quickly become a hindrance for development progress and a frequent source of errors in the MCD tool chain.

These delimiters prevent ambiguous interpretation. Calibration tools can now show measurement variables and calibration parameters as part of a data structure. This approach has the advantage that calibration engineers can work with data formats that are understandable and meaningful to them.
