英文摘要: Automotive applications are typically time-critical and safety-critical. It's a big challenge on how to build such applications on vehicle networks which are characterized by embedded、realtime and heteromerous. Guided by the view of Cyber-Physical System, this project will focus on the key scheduling theories and techniques for vehicle networks. Firstly, scheduling model will be abstracted,then schedulability analysis will be presented completely, thirdly, some scheduling algorithms aim to improving predictability and reliability will be proposed, finally, a prototype for validating theories and algorithms will be built. These studies will lead to a clear view of message scheduling in vehicle networks which mixed event-triggered and time-triggered mechanics,and can be used to build a better vehicle networks under the Cyber-Physical System environment.
