Research Of CAN Network Management Based On AUTOSAR

With the increasing functional requirements and security requirements invehicles, more and more electronic control units are introduced into cars, whichcauses a technical change in vehicle control aspect.The idea of taking a car as awhole unit is leading a direction of networked.This is a challenge not only to theautomobile manufacturers, but also make new demands on the safety and reliabilityof the network communication. The open architecture standard AUTOSARautomotive network protocol provides a unified development platform andstandards, this will not only reduce the manufacturing costs, but also shorten thegap of automotive electronic technology between our country and foreign countries,improve our core competitiveness and accelerate the industrialization of it. In thisthesis, a large number of research domestic and foreign are collected and analyzed,and on this basis, a network management method with AUTOSAR standard isresearched and improved,then the improved method on CAN bus with AUTOSARsoftware architecture is implemented.The thesis first describes the background and significance of the vehiclenetwork management, analyzes the network management research status both athome and abroad. Then, analyzes the basic working principle of the OSEK networkmanagement and AUTOSAR network management,on this basis, directing at theinsufficient of AUTOSAR network management function on sleeping and errordetection, a method to improve the AUTOSAR network management is put forwardin this thesis. On account of AUTOSAR software standard, provides the realizationof network management method under CAN bus. At last, a simulation experimentsabout CAN bus network management solution is taken in CANoe, and the resultsverify that the solution is feasible.
