The invention discloses a circuit control method, device, equipment and system and a storage medium. The method comprises the following steps: acquiring a low-voltage sampling electric signal of the step-down DCDC circuit, wherein the low-voltage sampling electric signal is a sampling electric signal of an output electric signal of the step-down DCDC circuit; detecting the sampling state of the low-voltage sampling electric signal; if the sampling state of the low-voltage sampling electric signal is a sampling failure state, controlling the step-down DCDC circuit to work according to a first control mode; if the sampling state of the low-voltage sampling electric signal is a sampling effective state, the step-down DCDC circuit is controlled to work according to a second control mode; the first control mode is different from the second control mode. According to the application, whether the sampling of the output side electric signal is normal can be identified, and when the sampling of the output side electric signal is abnormal, the step-down DCDC circuit can continuously work through the high-voltage side electric signal, and meanwhile, the risk of vehicle anchoring is reduced.

    本申请公开了一种电路控制方法、装置、设备、系统以及存储介质。该方法包括:获取降压DCDC电路的低压采样电信号,低压采样电信号为降压DCDC电路的输出电信号的采样电信号;检测低压采样电信号的采样状态;若低压采样电信号的采样状态为采样失效状态,则按照第一控制模式,控制降压DCDC电路进行工作;若低压采样电信号的采样状态为采样有效状态,则按照第二控制模式,控制降压DCDC电路进行工作;上述第一控制模式与上述第二控制模式不相同。通过本申请,不仅可以识别输出侧电信号的采样是否正常,并且当输出侧电信号的采样异常时,可以通过高压侧电信号使降压DCDC电路持续工作,同时减小车辆抛锚风险。
