TTP/C在汽车网络中应用的研究

近年来,伴随着汽车电子系统网络化进程的加快,CAN作为一种事件驱动型的网络,无法提供下一代线控系统应用所需的容错功能或带宽,因此又有许多新型网络被开发出来。如以TTP/C(Time Triggered Protocol,Class C)为代表的X-线控(X-by-wire)技术在车载网络中的应用日益成熟,汽车"线控"系统对控制动作的实时性和系统可靠性要求非常高,因此,使用时间触发的协议对安全性要求高的转向和制动等方面是有利的。

As event driven network ,Unable to provide the next generation of application-by-wire systems need fault tolerance or bandwidth, Therefore there are many networks have been developed, network technology of TTP/C in Vehicle has become more sophisticated, ＂by-wire＂systems of Vehicle to control movements of real-time and reliability requirements of a very high demands,Therefore, the use of time-triggered protocol for security demanding areas such as steering and brakes is beneficial.
