摘要
为实现电动轮车电子差速控制时整车的通信,设计了电动轮车CAN网络。结合电动轮车的高性能通信要求,设计了整车CAN网络结构及通信协议,并利用总线开发工具CANscope研究了其网络通信性能,进行了网络系统调度分析和网络负载率分析。4轮独立驱动电动轮车实车在电子差速控制试验时,采用该整车CAN网络进行多传感器与多控制器之间通信,可实现4轮的转向差速控制,验证了该整车CAN网络系统的实时性、可靠性和有效性。
A CAN network was designed to achieve the vehicle communication for the electronic differential control in in -wheel motor drive electric vehicle .The CAN network structure and communication protocol were designed to satisfy the high performances of communication .CANscope, a kind of bus development tool , was applied to research the communication performance, including the CAN bus scheduling and bus load rate .During the experiment of electronic differential control , this CAN network could complete the communication among several sensors and controller units so that the electronic differential control among four wheels was achieved .The experiment results validate the real -time, reliability and effectiveness of this CAN network .
