The invention provides a vehicle power saving method and system. The method comprises the following steps of obtaining the starting working condition of a vehicle engine and the electric quantity consumption working condition of a storage battery; when it is detected that the vehicle engine is in the non-starting state and the storage battery is in the power consumption state, obtaining the powersaving level of the storage battery in the current state; when it is detected that the storage battery is in a first preset power-saving level state, sending vehicle power shortage information; and when it is detected that the vehicle power shortage information is not received within the preset information receiving time range, controlling the vehicle to execute a power saving operation instruction of entering a second power saving level state. According to the vehicle power saving method and system, the vehicle power shortage information is sent when whether the storage battery enters the first preset power saving level state or not is judged, and when the vehicle power shortage information is not processed in time, the vehicle is controlled to enter the second power saving level state, so that the storage battery is effectively protected under any working condition, and the situation of power shortage of the vehicle storage battery is prevented to the greatest extent.

    本发明提供车辆节电方法及其系统,方法包括如下步骤:获取车辆发动机的启动工况和蓄电池的电量消耗工况;当检测到车辆发动机处于未启动状态、而蓄电池处于耗电状态时,获取蓄电池当前状态下的节电等级;当检测到蓄电池处于第一预设节电等级状态时,发送车辆电量不足信息;当检测到在预设信息接收时间范围内车辆电量不足信息未被接收时,控制车辆执行进入第二节电等级状态的节电操作指令。本发明提供车辆节电方法及其系统,在判断蓄电池是否进入第一预设节电等级状态时发送车辆电量不足信息,当车辆电量不足信息未被及时处理时,控制车辆进入第二节电等级状态,实现在任何工况下对蓄电池进行有效保护,最大程度地防止车辆蓄电池亏电的情况发生。
