The invention relates to the technical field of intelligent driving, and discloses a driving style identification method and device, computer equipment and a storage medium, and the method comprises the steps: obtaining driving behavior data, determining a local identification model based on a training data set, and obtaining a driving style identification model according to a first number in the training data set and a proportion of samples belonging to a first category in the training data set; determining the reliability weight of the local recognition model, summarizing the driving style prediction results based on the driving style prediction results and the reliability weight of the local recognition model, determining total driving style probability distribution, and training a global model based on the total driving style probability distribution; and optimizing the local identification model based on the prediction result of the global model. A lightweight driving style model is realized at a vehicle end, a global model is adopted at a cloud end, the global model is a complex recognition model, and under the condition that the models are heterogeneous, the capability of the global model is integrated on the premise of not obtaining privacy driving data, so that higher accuracy and robustness are realized.

    本发明涉及智能驾驶技术领域,公开了驾驶风格识别方法、装置、计算机设备及存储介质,包括获取驾驶行为数据,基于训练数据集确定本地识别模型,根据训练数据集中的第一数量以及训练数据集中属于第一类别的样本比例,确定本地识别模型的可靠性权重,基于驾驶风格预测结果和本地识别模型的可靠性权重对驾驶风格预测结果进行汇总,确定总驾驶风格概率分布,基于总驾驶风格概率分布训练全局模型;基于全局模型的预测结果对本地识别模型进行优化。在车辆端实现轻量化驾驶风格模型,在云端采用全局模型,全局模型是复杂识别模型,在模型异构的情况下,在不获取隐私驾驶数据的前提下综合汇终端模型的能力,实现更高的准确率和鲁棒性。
