Embodiment Construction

[0028] Below in conjunction with accompanying drawing and embodiment the present invention will be further described:

[0029] The system information extraction method for a single electronic control unit in the field of automotive electronics based on the directed graph structure of the present invention includes the following steps:

[0030] 1. Model an AUTOSAR system as a directed graph structure;

[0031] 1.1 Extract the standard XML file described by the AUTOSAR system configuration, parse and generate a tree structure with the inclusion relationship as the directed edge, and the tree node is the memory object created according to the AUTOSAR UML profile. The tree structure is consistent with the structure of the XML file itself.

[0032] 1.2 Analyze the various reference relationships contained in the XML file, and create new directed edges between the created tree nodes to represent the reference relationship. After adding the reference relationship, the original tree...

Abstract

The invention discloses a directed-graph-structure-based system information extraction method for a single electronic control unit (ECU). The method comprises the following steps of: 1) converting an information extraction process into a graph traversing process in a directed-graph-structure-based automotive open system architecture (AUTOSAR) modeling way; 2) supporting the stipulation of extraction rules into the three conditions of inclusion, citation and relation based on the data structure, and performing classification and definition by using declarative key-value pairs; and 3) traversing the directed graph structure of the whole system, and serializing labeled objects into extensible markup language (XML) files as final ECU extraction results. The method has the advantages that: a high-efficiency model structure is disclosed, the problems of a great number of complex system information extraction rules in an AUTOSAR standard and low efficiency of the conventional method can be effectively solved, and the extraction process can be rapidly and accurately finished; and improvement on the performance of a tool and great reduction in development difficulty are realized by the stipulation of the system information extraction rules, and the structure of the object can be integrally preserved, so that iterative development can be effectively supported.

Description

technical field [0001] The invention relates to the development technology of automobile electronic software, in particular to a method for extracting system information of a single electric control unit based on a directed graph structure. Background technique [0002] AUTOSAR (AUTomotive Open System ARchitecture) is an open system architecture for automotive electronics. System information extraction for a single Electronic Control Unit (ECU) is an important link defined in the AUTOSAR methodology ("ECU extraction" for short). After completing the The ECU configuration tool played an important role in the system conversion process. [0003] The main task of an ECU extraction tool is to extract information related to a specific EUC from the system. The extracted results will be used as the basis for subsequent configuration tools. In order to ensure that the focus and manageability of subsequent configurations are not affected by the complexity of the entire system, ECU e...
