The Design Of Automobile Diagnostic And Communication System Based On AUTOSAR

With the development of the automobile industry, the automobiles became moreand more intelligent, and more on-board electronic equipment had been used in thecars. This topic bases on analyzing the development of automobile electronictechnology and the AUTOSAR standard.It mainly descreibes the general plan ofFunction Inhibition Manager, and the overall design plan of J1939Tp module.The Function Inhibition Manager besed on AUTOSAR standard is responsible forproviding a control mechanism for software components and functionality therein.Meanwhile, the FIM module is configurable and suitable for many situations.TheJ1939communnication stack is divided into2parts: the J1939application layer andthe J1939transport layer. Under this circumstance, the J1939App layer provides theexplicit interfaces for sending and reciveing the PGs, and the J1939Tp layer providesthe data comunicaiong through the physical layer,including the nessesarysynchronous、sequential control,the error recovery and stream control.Based on the analysis of AUTOSAR, draw the FIM module and the J1939tp module,and provide part of the software design.This design adopt module designphilosophy.To the question of a good real time and high anti-interference which isneeded by the auromobile control system, we design and realize those modules.
