基于XC2268N的独立网关设计与实现

Design and Implementation of Independent Gateway Based on XC2268N

针对整车信息化多种网络和多网段数据信息交流的需要,开发和实现以XC2268N为主控制器的车载独立网关,该系统包含6路独立CAN节点,4路独立LIN节点,并基于USIC(ASC)技术实现整车基于网关的数据和信号交换,以达到路由信息在不同通信协议间进行转换的目的,且具有整车网络管理、UDS诊断、BT下载、休眠唤醒等功能。经过对某车辆独立网关系统的台架试验与实车验证,表明该系统具有实时性好、可靠性高、性价比高的优点。

In order to meet the requirement of multi-network and multi-segment data and information exchange in vehicle, an on-board independent gateway based on XC2268N is developed. The system consists of 6 independent CAN nodes and 4 independent LIN nodes. The data and signal exchange based on gateway is realized based on USIC(ASC)technology to achieve routing information. It has the functions of NM,UDS and BT. The test results of a vehicle independent gateway system show that the system has the advantages of good real-time performance,high reliability and high cost performance.
