摘要
为了满足汽车上越来越多的电子控制单元对信息共享的需求,现代汽车开始采用基于CAN总线的网络结构。首先介绍了CAN网络技术及其特点,提出了一种车身分布式CAN网络系统方案,以MC9S12DP512 16位单片机为核心设计了系统的软硬件,根据J1939协议制定了通信协议,该系统能够对车身电器进行网络化控制和状态反馈。通过搭建车身平台,证明所设计系统能满足设计功能。
To reach the need for information sharing along more and more ECUs on the automobile, CAN bus is being used. It introduces CAN network and its feature. And gives out the schemes about automotive body CAN network system. The particular hardware and software implementation of the system is designed with MC9S12DP512 microcontroller. The protocol is given based on J1939. This system can control car body equipments and reflects their states. The test indicates that the system can realize the required functions.
