The invention provides a vehicle power management unit control method and device, a vehicle and a storage medium, and relates to the technical field of vehicle electronic circuit control. The method comprises the steps of obtaining a working state of the power management unit; when the working state is an awakening state, working condition information of the power management unit is detected; judging a numerical value interval in which each item of working condition information is located to obtain a working condition information judgment result; and according to the working condition information judgment result, the vehicle body controller controls a power management unit switch to execute opening and closing actions corresponding to the working condition information judgment result. Therefore, the on-off state of the switch of the power management unit can be determined according to the specific numerical value interval of each item of working condition information, and the detection and protection precision of the power management unit on the overvoltage, undervoltage and overcurrent conditions of the vehicle-mounted redundant power supply system is improved.

    本申请提供一种车辆电源管理单元控制方法、装置、车辆及存储介质,涉及车辆电子电路控制技术领域。方法包括:获取电源管理单元的工作状态;当工作状态为唤醒状态时,检测电源管理单元的工况信息;判断每项工况信息所处的数值区间,以得到工况信息判断结果;根据工况信息判断结果,通过车身控制器控制电源管理单元开关执行与工况信息判断结果对应的开闭动作。如此,可以根据每项工况信息所处的具体的数值区间,确定电源管理单元开关的开闭状态,提升电源管理单元对车载冗余供电系统的过压、欠压及过流情况的检测和保护精度。
