The invention relates to the technical field of vehicle fault prompting, and provides a vehicle power system fault prompting method and device and a new energy vehicle. The method comprises the steps that when a vehicle has a power fault, a classification mark corresponding to the fault is recognized, the classification mark is one of a plurality of target classifications determined in advance based on a result caused by the fault and a preset vehicle state, and each power fault corresponds to one target classification in advance; detecting at least one vehicle target state when the power fault occurs based on the classification mark of the fault, wherein the at least one vehicle target state comprises a charging state and a motion state of the vehicle; and based on the classification mark of the power fault and the at least one vehicle target state, determining prompt content of the whole vehicle power system fault, and displaying the prompt content in a preset format. According to the prompt content sent for the power fault, the influence of factors such as the charging state and the motion state of the vehicle on the performance and the influence of the power system fault are fully considered, misleading and confusion can be reduced, and unnecessary confusion to a driver is avoided.

    本申请涉及汽车故障提示技术领域,提供了一种整车动力系统故障的提示方法、装置和新能源汽车,该方法包括:当车辆发生动力故障时,识别故障对应的分类标记,分类标记为预先基于故障导致的结果和预设车辆状态确定的多个目标分类之一,每种动力故障预先对应一个目标分类;基于故障的分类标记检测发生动力故障时的至少一种车辆目标状态,包括车辆的充电状态和运动状态;基于动力故障的分类标记和至少一种车辆目标状态,确定整车动力系统故障的提示内容,以预设格式显示提示内容。本申请针对动力故障发出的提示内容充分考虑了车辆的充电状态和运动状态等因素会影响动力系统故障的表现和影响,可减少误导和混淆,避免对驾驶员造成不必要的困惑。
