The invention provides a low-voltage power supply mode management method and device, a vehicle and a storage medium, and belongs to the technical field of vehicle positioning, and the method comprises the steps that the power supply mode of a whole vehicle power supply is obtained, and the power supply mode is any one of an OFF mode, an ON mode, a READY mode and a RUNNING mode; the operation state of the DCDC system is obtained, low-voltage power supply mode management strategies are determined based on the operation state of the DCDC system and the power supply mode, and the low-voltage power supply mode management strategies comprise a quiescent current management strategy, a load level-to-level management strategy, a DCDC management strategy and a limp control management strategy. The low-voltage power supply mode management strategy is determined on the basis of the power supply mode and the operation state of the DCDC system, power supply management in any power supply mode is achieved, power shortage of a low-voltage storage battery is avoided, normal power utilization of low-voltage electric equipment during next high-voltage power-on is ensured, then normal starting of a vehicle is ensured, and the experience feeling of a driver is improved.
本发明提供了一种低压电源模式管理方法、装置、车辆及存储介质,属于车辆定位技术领域,其方法包括:获取整车电源的电源模式,电源模式为OFF模式、ON模式、READY模式和RUNNING模式中的任意一种;获取DCDC系统的运行状态,并基于DCDC系统的运行状态和电源模式确定低压电源模式管理策略,低压电源模式管理策略包括静态电流管理策略、负载分级管理策略、DCDC管理策略以及跛行控制管理策略。本发明基于电源模式和DCDC系统的运行状态确定低压电源模式管理策略,实现在任意电源模式下的电源管理,避免低压蓄电池亏电,确保在下一次高压上电时低压用电设备的正常用电,进而确保车辆正常启动,提高驾驶员体验感。
