The invention relates to a load circuit control method and device, a medium and a vehicle, the load circuit control method is applied to a controllable power supply controller, the controllable power supply controller supplies power to an electronic control unit, and the electronic control unit is used for controlling the working state of a vehicle load. The load circuit control method comprises the steps that a first threshold current of a load circuit is determined based on the working state of a vehicle load, and the load circuit comprises an electronic control unit; detecting a real-time current of the load circuit; and comparing the first threshold current with the real-time current to obtain a first comparison result, and judging whether the load circuit has a short-circuit fault or not according to the first comparison result. Whether the load circuit works abnormally or not can still be judged under the condition that the load circuit has the on-load short-circuit fault, so that the diagnosis range of the fault condition of the load circuit is expanded, and the risk of vehicle burnout is further reduced.
本公开涉及一种负载电路控制方法、装置、介质及车辆,负载电路控制方法应用于可控电源控制器,可控电源控制器为电子控制单元供电,电子控制单元用于控制车辆负载的工作状态,负载电路控制方法包括:基于车辆负载的工作状态确定负载电路的第一阈值电流,负载电路包括电子控制单元;检测负载电路的实时电流;比较第一阈值电流和实时电流得到第一比较结果,并根据第一比较结果判断负载电路工作是否有短路故障。本公开实现了当负载电路中存在带载短路故障的情况下,仍可以判断负载电路是否工作异常,由此扩大了对负载电路故障情况的诊断范围,进一步降低了车辆烧毁风险。
