在安全性要求极高的一些车辆系统中,基于事件触发的CAN(Controller Area Network)已经不能满足要求。一种采用CAN的解决方法就是将标准CAN扩展成时间触发的协议。TTCAN(Time-Triggered CAN)就是这样一个扩展并且已经成为国际标准协议。...在安全性要求极高的一些车辆系统中,基于事件触发的CAN(Controller Area Network)已经不能满足要求。一种采用CAN的解决方法就是将标准CAN扩展成时间触发的协议。TTCAN(Time-Triggered CAN)就是这样一个扩展并且已经成为国际标准协议。本文对TTCAN进行大概的描述并介绍如何用mb90f543G来实现其第一层次扩展的方法。展开更多

Douhle CAN redundant communication have been realized among several hardware nodes based on μC／OS-II. The design mechanism, hardware and softy, are of double CAN communication were described in detail.
