The invention discloses a new energy vehicle CAN network management method comprising the following steps: carrying out function division on each controller of a whole vehicle CAN network; the direct network management controller executes a sleep waiting mode and a normal working mode according to a received sleep message and a wake-up message after the vehicle is started; the indirect network management controller starts to work after the whole vehicle is powered on and stops working after the whole vehicle is powered off. The method has the advantages that the control with lower power consumption is realized by managing dormancy and awakening among the controllers in the CAN network, and the power consumption of the whole vehicle is saved; the CAN network controllers are divided from the aspects of functions and safety, and the controllers capable of performing dormancy and wake-up operation are set according to requirements, so that the control is more accurate and reliable.

    本发明公开了一种新能源汽车CAN网络管理方法,包括:对整车CAN网络的各控制器进行功能划分,将其划分为直接网络管理控制器和间接网络管理控制器:其中直接网络管理控制器在车辆启动后根据接收到的睡眠消息、唤醒消息而执行睡眠等待模式、正常工作模式;间接网络管理控制器在整车上电后开始工作并在断电后停止工作。本发明的优点在于:通过对CAN网络中的各控制器之间进行休眠和唤醒的管理实现了更低功耗的控制,节约整车电量消耗;对各CAN网络控制器进行功能和安全角度的划分,按照需求来设定可以进行休眠和唤醒操作的控制器,控制更加准确可靠。
