Research on Real-time Performance of Aperiodic Message and OptimizedDesign of Bandwidth Allocation in Multifunction Vehicle Bus

Abstract

By analyzing the characteristics of every type of messages, two bandwidth allocation strategies of MVB aperiodic communicationwere proposed , and relevant formula was derived. In combination with the scheduling principles of aperiodic messages, theoptimized bandwidth allocation strategy were researched and compared. The real-time performance of aperiodic messages had greatlyimproved after the optimization of bandwidth allocation.
