The invention relates to a vehicle power shortage monitoring method and system and a medium. The method comprises the steps that a main node of a vehicle-mounted controller monitors a unit quiescent current consumption value of a storage battery of a current vehicle when the current vehicle enters a dormant state; when the unit quiescent current consumption value is greater than or equal to a preset unit quiescent current consumption value, the main node sends an awakening signal to a slave node of a vehicle-mounted controller; after the main node awakens the slave node through the awakening signal, the slave node judges whether abnormal awakening exists or not before receiving the awakening signal; if so, the slave node acquires own abnormal wake-up time and abnormal wake-up reason; and the slave node creates a DID of the slave node, and records the identifier of the slave node with abnormal wake-up, the abnormal wake-up time, the abnormal wake-up reason and the vehicle state data during abnormal wake-up in the DID created by the slave node. By implementing the method provided by the invention, the problem that the reason of power shortage of the vehicle is difficult to check canbe solved.
本发明涉及一种车辆亏电监测方法、系统及介质,所述方法包括:在当前车辆进入休眠状态时,车载控制器的主节点监测当前车辆的蓄电池的单位静态电流消耗值;在单位静态电流消耗值大于等于预设单位静态电流消耗值时,主节点发送唤醒信号至车载控制器的从节点;在主节点通过唤醒信号唤醒从节点后,从节点判断自身在接收到唤醒信号之前是否存在异常唤醒;若是,所述从节点获取自身的异常唤醒时间和异常唤醒原因;所述从节点创建自身的DID,并将存在异常唤醒的所述从节点的标识、异常唤醒时间、异常唤醒原因和异常唤醒时的车辆状态数据记录在自身创建的DID中。实施本发明,可解决车辆亏电原因难以排查的问题。
