The invention discloses a vehicle power saving control method and device, and relates to the technical field of vehicle power saving. A central computing platform issues a network management message with a PN identifier and a power-on instruction to an area controller, and the area controller awakens a sub-network segment and a node corresponding to the PN identifier based on the network management message with the PN identifier, and supplies power to the node corresponding to the PN identifier based on the power-on instruction. In this way, only the area controller, the sub-network segment and the node corresponding to the PN identifier are awakened, only the node corresponding to the PN identifier is powered on, other sub-network segments on other area controllers and the area controller corresponding to the PN identifier are all in a dormant state, and other nodes are not powered on, so that the power consumption of the whole vehicle in a dormant awakening scene is greatly reduced.

    本发明公开了车辆节电控制方法及装置,涉及车辆节电技术领域。本发明的中央计算平台向区域控制器下发带PN标识符的网管报文和上电指令,区域控制器基于带PN标识符的网管报文唤醒PN标识符对应的子网段和节点,基于上电指令对PN标识符对应的节点进行供电,使得仅有PN标识符对应的区域控制器、子网段和节点被唤醒,仅有PN标识符对应的节点上电,其它区域控制器、PN标识符对应的区域控制器上其它的子网段均处于休眠状态,其它节点也未上电,极大的降低了休眠唤醒场景下的整车电能消耗。
