Research on FlexRay Message Slot Distribution Methods Based on Bus Occupancy Rate
摘要
Abstract
Message slot distribution method is one of the key problems of design of FlexRay vehicle bus.On the basis of analyzing characteristics of FlexRay and its frame of format and physical layer transmission features,methods of calculating message frame slots and bus occupation rate were obtained,factors that influenced on bus occupation were given herein.With the goal of minimal bus occupation rate,a message frame slot distribution method was proposed which assigned the longest static message frame to the dynamic segment.By example validation,the proposed message frame slot method is proved to be feasible,it reduces bus occupation rate effectively,and increases efficiency of the network.关键词
