摘要
在自主研发的CAN总线实时仿真系统上，通过软件编程，分别实现了CAN协议通讯和TTCAN（Time-Triggered CAN）协议时间触发通讯。通过对两种不同通讯协议下的网络实时性进行比较，分析了TYCAN通讯网络的实时性。研究结果表明，引入TTCAN协议的时间触发功能能解决CAN协议中的总线冲突问题，有效提高了实时性要求较高的周期型消息的实时性。
The communication based on the protocol of CAN （Controller Area Network）and TFCAN （Time-Triggered CAN）was implemented by programming on the real-time simulation system for the CAN bus, and the real-time performance of the communication was analyzed. The results indicate that the bus conflict in the event-triggered CAN network can be resolved and the real-time performance of the periodic message can be improved by adopting the time-triggered function of TFCAN protocol.
