The invention relates to the technical field of thermal management systems, in particular to a fault diagnosis method for a thermal management system, a vehicle and cloud equipment, and the method comprises the steps: recognizing a feature signal of an operation parameter of the thermal management system; when the feature signal meets a preset abnormal condition, storing related data of the feature signal before and after a preset duration; and diagnosing the fault of the thermal management system based on related data of preset duration before and after the feature signal. Therefore, the problems that in the related technology, fault checking and positioning are only carried out when the vehicle system breaks down, the situation that early warning is not timely, and consequently serious consequences are caused exists, the vehicle safety performance is low, and the user experience feeling is poor are solved.

    本申请涉及热管理系统技术领域,特别涉及一种热管理系统的故障诊断诊断方法、车辆及云端设备,其中,方法包括:识别热管理系统的运行参数的特征信号;当特征信号满足预设异常条件时,则存储特征信号前后预设时长的相关数据;基于特征信号前后预设时长的相关数据诊断热管理系统的故障。由此,解决了相关技术中仅在车辆系统发生故障时进行故障的排查和定位,存在预警不及时导致严重后果的情况,车辆安全性能较低,用户体验感较差等问题。
