Abstract

The invention discloses a method for extracting communication matrixes from AUTOSAR (Automotive Open System Architecture) system allocation models. The method comprises the steps of: analyzing and obtaining communication matrix information of a communication cluster from an AUTOSAR system; confirming the communication cluster to be analyzed and obtaining a physical channel included in the communication cluster; obtaining all electronic control units in a connection relationship with the communication cluster in the system and establishing a hash table that an electronic control unit communication interface included in the electronic control units reaches a physical channel linked list; obtaining a frame trigger connected with each physical channel so as to obtain a data link layer frame corresponding to the frame trigger, and establishing a hash table that the physical channel reaches a data link layer frame linked list; calculating system signals included in each data link layer frame and establishing a hash table that the system signals reach the data link layer frame linked list; and establishing a communication matrix digraph, so that the hidden danger that errors may happen in network signal allocation by a multi-layer AUTOSAR system is brought forward to a system allocation stage, and the development efficiency is improved.

Description

technical field [0001] The invention relates to the development technology of automobile electronic software, in particular to a method for extracting a communication matrix from an AUTOSAR system configuration model. Background technique: [0002] AUTOSAR (AUTomotive Open System ARchitecture) is an open system architecture for automotive electronics. System Configuration is an important part of AUTOSAR methodology. It defines configuration information such as hardware topology, network communication, and system mapping in the system. System mapping specifies The mapping relationship between software components and electronic control units in the system, the mapping relationship between data elements and network signals, the relationship between sending and receiving network signals at the ports of electronic control units, etc., realizes the decoupling of software and hardware. [0003] The hardware topology specifies the hardware information in the system, which is the con...
