设计了基于CAN/LIN通讯协议的分布式车身网络系统，并对其低功耗进行了研究。从硬件上提出了节点的低功耗设计方法，并分析了节点能耗主要来源，提出动态电压调节和动态能量管理的控制策略；结合操作系统的空闲任务，从软件上给出了两种系统进人低功耗模式的方法，利用CAN/LIN总线实现了单节点到整个系统的唤醒。经台架验证可知，该设计可以显著降低车身控制系统的功耗。

The distrivuted-vased auto-vody network vased on CAN/LIN communication protocol is designed, and its low power consumption strategy is analyzed. The low power consumption design method of node for hardware is proposed and the main source of energy consumption of node is analyzed, and dynamic voltage scaling (DVS) and dynamic power management (DPM) control strategies are put forward. In consideration of the idle tasks of the operation system, two different approaches to access to the low power-consumption mode are suggested, and we adopt CAN/LIN vus to enavle wake-up from single node to the whole auto-vody control system. We conclude from vench test that such design can greatly reduce the power consumption of vody control system.
