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.
