The invention relates to a power supply control method and device, a vehicle-mounted terminal and a vehicle. The method comprises the following steps: determining whether a target vehicle is in a closed state or not according to a controller area network CAN bus signal of the target vehicle; if yes, the static current of the target vehicle is monitored, and whether the static current is abnormal or not is determined; when it is determined that the static current is abnormal, a power supply relay of the target vehicle is switched off, so that the target vehicle is controlled to enter a power locking state; wherein in the power locking state, a power supply of the target vehicle stops supplying power; and under the condition that an unlocking request for the target vehicle is detected, the power supply relay is controlled to be closed according to the unlocking request, so that the power supply of the power supply of the target vehicle is restored. The method can reduce the consumption of a large amount of electric quantity of the storage battery during the parking period of the vehicle.

    本申请涉及一种电源控制方法、装置、车载终端和车辆。所述方法包括:根据目标车辆的控制器局域网络CAN总线信号,确定所述目标车辆是否处于关闭状态;若是,则对所述目标车辆的静电流进行监控,并确定所述静电流是否存在异常;在确定所述静电流存在异常的情况下,断开所述目标车辆的电源继电器,以控制所述目标车辆进入锁电状态;其中,在所述锁电状态下,所述目标车辆的电源停止供电;在检测到对所述目标车辆的解锁请求的情况下,根据所述解锁请求,控制所述电源继电器闭合,以使所述目标车辆的电源恢复供电。采用本方法能够减少在车辆停放期间,蓄电池电量的大量消耗。
