The invention provides an AUTOSAR-based network management system and method for a hydrogen energy automobile, and the method comprises the steps: indicating that a transmitting node managed by a network intends to maintain the awakening state of the network when the node receives an NM message frame; and when the node stops sending the NM message frame, indicating that the node is ready to enter a sleep state. And when the KL15 is in an OFF state, the node immediately enters a ready-to-sleep mode, stops sending the NM message frame and prepares to enter a bus sleep state. The invention has the beneficial effects that the related comfort and safety functions of the hydrogen energy automobile are self-checked after the whole automobile is powered off, and the starting reliability is improved; meanwhile, the dark current of the whole vehicle after the vehicle is powered off is reduced, so that the static power consumption of the whole vehicle is reduced.
本发明提供了一种氢能汽车的基于AUTOSAR的网络管理系统及方法,当节点接收到一个NM消息帧时,表示该网络管理的发送节点意图保持网络的唤醒状态。当节点停止发送NM消息帧时,表示该节点准备进入睡眠状态。当KL15为OFF状态时,该节点立即进入预备睡眠模式,并停止发送NM消息帧,准备进入总线睡眠状态。本发明的有益效果是:满足了氢能汽车的相关舒适性、安全性功能在整车下电后的自检,提高了启动的可靠性;同时减少了车辆在下电后的整车暗电流,从而降低整车的静态功耗。
