The embodiment of the invention provides a fault detection method, device and system, electronic equipment and a storage medium, and relates to the technical field of new energy automobiles. The method comprises the following steps: performing feature extraction on vehicle data to obtain first feature data; inputting the feature data into a fault diagnosis model for detection, wherein the fault diagnosis model is obtained by training a machine learning model through the cloud processor by using vehicle big data and user feedback fault data; if the detection result is a coolant insufficiency fault, the detection result is sent to a man-machine interaction terminal to obtain a real vehicle detection result fed back by a user; and the real vehicle detection result is sent to the cloud server so as to carry out cycle training on the fault diagnosis model. According to the method, the fault diagnosis model is established by using the vehicle big data, effective data are accumulated along with the operation of the vehicle, the accuracy of the diagnosis result is improved by cyclically training the fault diagnosis model, and the problem of inaccurate diagnosis result of the existing method is solved.

    本申请实施例提供一种故障检测方法、装置、系统、电子设备及存储介质,涉及新能源汽车技术领域。该方法包括对本车数据进行特征提取,获得第一特征数据;将特征数据输入故障诊断模型进行检测,故障诊断模型是云端处理器利用车辆大数据和用户反馈故障数据对机器学习模型进行训练得到的;若检测结果为冷却液不足故障,则将检测结果发送至人机交互终端,以获得用户反馈的实车检测结果;将实车检测结果发送至云端服务器,以对故障诊断模型进行循环训练。该方法利用车辆大数据建立故障诊断模型,随着车辆的运行,积累有效数据,通过循环训练故障诊断模型,提高诊断结果的准确性,解决了现有方法诊断结果不准确的问题。
