The invention relates to a vehicle-mounted power supply maintaining system and method, a storage medium and a vehicle, and the system comprises a first circuit which is configured to carry out boosting processing on a system access voltage; an MCU module configured to perform a power down processing operation; the processing module comprises a first comparison unit and an MCU control unit, the first comparison unit is configured to compare the access voltage with a first threshold value, and the MCU control unit is configured to send an interrupt signal to the MCU module when the access voltage is smaller than the first threshold value. According to one or more embodiments of the invention, the requirement of communication route maintenance after vehicle collision can be realized through a software and hardware scheme, and the purposes of cost optimization and development cycle optimization are achieved.

    本发明涉及车载电源维持系统、方法、存储介质以及车辆,该系统包括:第一电路,第一电路配置成对系统接入电压进行升压处理;MCU模块,其配置成执行掉电处理操作;以及处理模块,其包括第一比较单元和MCU控制单元,其中,第一比较单元配置成将接入电压与第一阈值进行比较,MCU控制单元配置成在接入电压小于第一阈值时向MCU模块发送中断信号。根据本发明的一个或多个实施例可以通过软硬件的方案实现车辆碰撞后的通信路由维持的要求,并达到成本优化、开发周期优化的目标。
