The invention belongs to the technical field of personalized driving, and relates to an in-transit driving style identification method based on driving behavior semantic understanding. According to the method, on-road driving operation is considered from multiple dimensions based on vehicle track information, and potential driving style features of a driver are rapidly extracted and recognized. The method comprises the following steps: firstly, establishing a driving behavior semantic understanding rule, and dispersing continuous track time sequence data into driving behavior semantic understanding vocabularies from a decision layer, an operation layer, a mode layer and a scene perception layer of driving work; secondly, defining a plurality of driving styles according to a theme confusion index; and finally, identifying the in-transit driving style of each driver as a probability combination of different driving styles so as to reflect the current driving state of the driver. According to the in-transit driving style identification method provided by the invention, the phenomenon that the driving styles of the same driver in different driving environments are different is explained, and meanwhile, the comprehensiveness and the understandability of in-transit identification of the driving styles are improved.

    本发明属于个性化驾驶技术领域,涉及一种基于驾驶行为语义理解的在途驾驶风格识别方法。本发明基于车辆轨迹信息从多维度考虑在途驾驶作业,对驾驶员潜在驾驶风格特征进行快速提取和识别。首先,建立驾驶行为语义理解规则,从驾驶作业的决策层、操作层、模式层以及场景感知层出发,将连续的轨迹时序数据离散为驾驶行为语义理解词汇;其次,根据主题困惑度指标定义多种驾驶风格;最后,将每位驾驶员的在途驾驶风格识别为不同驾驶风格的概率组合,以反映驾驶员当前驾驶状态。本发明提出的在途驾驶风格识别方法解释了同一驾驶员在不同驾驶环境下表现的驾驶风格存在差异性的现象,同时提高了驾驶风格在途识别的全面性以及可理解性。
