The invention discloses a driving style dynamic identification method in an Internet of Vehicles environment, and belongs to the field of traffic safety. Decisions of drivers have subjective differences, and the driving auxiliary system considering driver decision habit differences can improve active safety efficiency and accuracy. According to a traditional driving style identification method, driving habits of a driver are investigated and scored mainly through a series of traffic psychology questionnaires, and then the driving style is obtained. However, an obtained result is often different from the performance of a driver on an actual road, and meanwhile, a scoring mode is also not suitable for real-time driving style detection in an Internet of Vehicles environment. According to the invention, learning and training of a driving style identification threshold are carried out by using multi-scene trajectory data through an unsupervised machine learning method, aggressive drivers are detected in real time through communication computing capabilities of a central cloud control platform and a vehicle-mounted end platform in a network connection environment, and finally a personalized early warning strategy is formulated. The method can be applied to active safety early warning under the background of an intelligent network connection technology.
一种车联网环境下驾驶风格动态识别方法属于交通安全领域。驾驶员的决策具有主观差异性,考虑驾驶员决策习惯差异的驾驶辅助系统,可以提升主动安全效率和准确性。传统的驾驶风格识别方法主要通过一系列交通心理学问卷对驾驶员的驾驶习惯进行调查和评分进而获得驾驶风格。然而获得的结果往往与驾驶员在实际道路上的表现不一样,同时评分的方式也不适用于车联网环境下的实时驾驶风格检测。本发明利用多场景轨迹数据通过无监督机器学习方法进行驾驶风格识别阈值的学习和训练,并通过网联环境下中心云控平台和车载端平台的通信计算能力实时检测激进型驾驶员,最后制定个性化的预警策略。本发明可应用于智能网联技术背景下的主动安全预警。
