The invention discloses a driving style online evaluation method. The method comprises the following steps: extracting driving behavior data of a plurality of straight or turning road sections; segmenting the driving behavior data of the straight or turning road section into a plurality of road section elements based on a Bayesian condensation type sequence segmentation algorithm; clustering the road segment elements corresponding to each road segment into different categories based on a variable coupling potential Dirichlet allocation model; assigning values to different classes based on the kinetic energy of the clustered different classes of road segment elements; based on the category assignment of the road segment primitives of any road segment, obtaining a road segment primitive average intensity value Q, a road segment primitive transfer diversity value D and a road segment primitive transfer tendency value T of any road segment; obtaining a driving style evaluation value J of the road section based on the driving style comprehensive evaluation function; based on the driving style evaluation value J, obtaining the driving style of the road section; the problems that a large amount of manpower and material resources are consumed during traditional driving style evaluation and calculation is tedious in the research process are solved.

    本发明公开了一种驾驶风格在线评价方法,包括以下步骤:提取若干直行或转弯路段的驾驶行为数据;基于贝叶斯凝聚型序列分割算法将直行或转弯路段的驾驶行为数据分割为若干路段基元;基于变量耦合的潜在迪利克雷分配模型对每个路段对应的路段基元进行聚类,分为不同类别;基于聚类后的不同类别路段基元的动能大小,对不同类别进行赋值;基于任意一路段的路段基元的类别赋值,获取任意一路段的路段基元平均强度值Q、路段基元转移多样性值D、路段基元转移倾向性值T;基于驾驶风格综合评价函数得到路段的驾驶风格评价值J;基于驾驶风格评价值J,得到路段的驾驶风格;解决了传统驾驶风格评价时耗费大量人力物力且在研究过程中计算繁琐的问题。
