ASAM_XCP_MCD-2 MC(ASAP2&A2L)_V1.6 是由Association for Standardisation of Automation and Measuring Systems (ASAM)发布的测量和校准数据规格文档。此版本是1.6，日期为2009年2月1日。文档的主要关注点在于ASAM MCD-2 MC，这是一种用于汽车标定(A2L)和XCP（eXtended Controller Area Network）开发的标准接口规范，适用于 ASAP2 (Advanced System Architecture for Processors) 和类似平台。该文档详细介绍了如何利用ASAM XCP进行汽车电子系统间的通信，特别是在发动机管理和控制（ECU）之间的通信。它涵盖了关键概念如软件接口设计、数据模型定义、通信协议实现以及A2L（Automatic Test Adapters for Processors）的要求，即为硬件诊断和在线校准过程提供标准化方法。ASAM MCD-2 MC确保了不同供应商开发的ECUs能够通过XCP进行无缝集成，并且支持远程诊断和维护功能。文档作者包括来自多家知名汽车电子供应商的企业专家，如Continental Automotive GmbH、dSPACE GmbH、ETAS GmbH、Robert Bosch GmbH、Vector Informatik GmbH等，这体现了其广泛的专业背景和行业共识。然而，ASAM强调尽管文档经过精心制作，但不保证完全无误或一致性，也不承担因使用本文档导致的任何损失或后果的责任。 ASAM保留随时修订文档的权利，因此用户在使用ASAM_XCP_MCD-2 MC V1.6时需要注意文档的最新状态，以确保与最新标准和最佳实践保持一致。这份规范对于从事汽车电子系统开发的工程师、制造商和测试人员来说，是一项重要的参考资料，帮助他们遵循行业标准，提升车辆系统的可靠性和效率。

Introduction

1.4.2 R

ESTRICTION FOR

RACKETS

ASAM MCD-2MC V1.6 requests always brackets of the form '/begin' '/end'. Curly brackets

'{' '}' are no longer supported.

1.4.3 W

32 API

S FOR

EED

EY AND

HECKSUM

ALCULATION

The definition of Win32 APIs for Seed&Key and checksum calculation which was formerly part of

the ASAM MCD-2MC V1.51 specification is no longer part of this specifiation. These definitions are

now found at [ASAM AE COMMON SEED&KEY].

1.5 E

NCODING OF THE

A2L

FILE

ASAM MCD-2MC files are used in different language areas. To support the different

character sets used in the different language areas it is necessary to add to the ASAM

MCD-2MC file the information about the used character set.

The ASCII and ISO-8859-x character sets, defined for several language areas are not

sufficient. The ASAM MCD-2MC files needs to be exchangeable world wide.

1.5.1 U

NICODE

RANSFORMATION

ORMAT

World wide exchange is supported by "Unicode Transformation Format" (UTF). Currently

there are 3 relevant versions of UTF available: UTF -8, UTF-16, UTF-32.

UTF-8 is compact and supports nearly every possible character world wide. Therefore

UTF-8 is the preferred encoding for ASAM MCD-2MC files.

Note:

Tools shall support at least UTF-8.

1.5.2 B

YTE

-O

RDER

ARK

The encoding that is used for the ASAM MCD-2MC file is defined in a Byte-Order Mark

(BOM). The BOM is a byte sequence at the beginning of the ASAM MCD-2MC file.

Currently defined BOM sequences:

Table 3 byte-order mark coding

Bytes Encoding Form

00 00 FE FF UTF-32, big-endian

FF FE 00 00 UTF-32, little-endian

FE FF UTF-16, big-endian

FF FE UTF-16, little-endian

EF BB BF UTF-8

If no encoding can be detected, ISO-8859-1 (Latin-1) encoding is used.

Note: For data type "ident" the restrictions listed in chapter 3.2 "Predefined data types"

are valid.

Note:

For user defined tags and enum values in AML the restrictions defined in chapter

5.2 "Format of the ASAM MCD-2MC Meta Language" are valid.

Division of the description data

2 DIVISION OF THE DESCRIPTION DATA

The definition of the ASAM MCD-2MC interface and hence the specification of the ASAM

MCD-2MC data base is aimed at defining a database independently of a computer or an

operating system in such a way that a transparent and manufacturer-independent

standard is established. As exchange format for such ECU descriptions *.a2l files are

used.

From the calibration point of view the database in accordance with the ASAM MCD-2MC

interface contains the complete description of all control unit relevant data in a project. A

project consists of project specific header, which is typically created by the project

manager, data and one or more control unit specific descriptions. These control unit

descriptions (= description of an ECU) include all conversion formulas and explanations

about the applicable (adjustable) and measurable (non-adjustable) quantities and present

a format description of the interface specific parameters. The measurement and

calibration system needs only to evaluate the quantities (and their conversion etc.), but

not the interface specific parameters. The latter are only passed on to the structures of the

driver. To make sure that these structures are correctly filled the MCD must know the

parameter type. The type is communicated with the ASAM MCD-2MC metalanguage. As

exchange format for such ECU IF Data descriptions *.aml files are used.

A project may include the control unit descriptions of various control units from different

suppliers. The descriptions differ in terms of content, but use a common information

storage methodology to allow for a global management of the project components. An

INCLUDE mechanism allows to summarize the various control unit descriptions of various

projects (Single-Source-Concept).

The ASAM MCD-2MC database thus consists of a number of different subcomponents

structured in accordance with the following diagram. The MODULE keyword denotes an

independent ECU or device.

PROJECT

{

HEADER{...} /* Project description */

MODULE Device

{

MOD_PAR{...} /* Control unit management data */

MOD_COMMON {...} /* Module-wide (ECU specific) definitions */

CHARACTERISTIC{...} /* Adjustable objects */

CHARACTERISTIC{...}

...

AXIS_PTS{...} /* Axis points objects */

AXIS_PTS{...}

...

MEASUREMENT{...} /* Measurement objects */

...

COMPU_METHOD{...} /* Conversion method */

COMPU_METHOD{...}
