The invention provides a vehicle quiescent current control method, device and system and a vehicle, belongs to the technical field of vehicles, and aims at defining the abnormal position of the quiescent current, improving the efficiency of abnormality checking and avoiding the power shortage of a vehicle storage battery. The method comprises the steps that in response to quiescent current abnormality, abnormality diagnosis is executed on a plurality of controller sets, and the abnormal position of the quiescent current is determined; the abnormality diagnosis comprises the following steps: cutting off power supply of at least one first controller group in the plurality of controller groups, and detecting quiescent current of a second controller group of which the power supply is not cut off; based on the quiescent current of the second controller group, determining whether the at least one first controller group is an abnormal controller group with abnormal quiescent current; if yes, abnormal diagnosis is ended, and power supply cut-off of at least one first controller group is kept; if not, the abnormal diagnosis is repeatedly executed until the power supply of the plurality of controller groups is cut off as the first controller group in the abnormal diagnosis, or the controller group is determined to be an abnormal controller group.

    本发明提供了一种车辆静态电流的控制方法、装置、系统及车辆,属于车辆技术领域,旨在明确静态电流异常位置,提高异常排查的效率,避免车辆蓄电池的亏电,所述方法包括:响应于静态电流异常,对多个控制器组执行异常诊断,异常诊断包括:切断多个控制器组中至少一个第一控制器组的供电,并检测未被切断供电的第二控制器组的静态电流;基于第二控制器组的静态电流,确定至少一个第一控制器组是否是静态电流异常的异常控制器组;若是,则结束异常诊断,并保持至少一个第一控制器组的供电切断;若否,则重复执行所述异常诊断,直到多个控制器组均在异常诊断中作为第一控制器组被切断供电,或者其中的控制器组被确定为异常控制器组。
