| Abstract: | Aiming at improving the communication efficiency of the CAN bus ,and meeting the requirement of Realtime activities . On the basis of existent simulation platform , this paper introduces a Data - Reduction Algorithm that can be applied to all data classes found in automotive multiplexing including body CAN and engine - related CAN to improve the information exchange rate among various intelligent nodes . It can be also applied to nonautomotive applications in which extensive information exchange is performed among control modules via a multiplex bus. Which can greatly improve the utilization of the bus , reduce average message delay time , max delay time and average message queue length . |
