The invention discloses a driving style intelligent identification method based on natural driving data, and the method comprises the steps: obtaining vehicle track data according to the natural driving data, and dividing the vehicle track data into a following data set and a lane changing data set; driving style characterization parameters in a car following state and a lane changing state are obtained, and a driving style principal component score matrix is obtained after dimension reduction processing; constructing a driving style clustering model and a driving style identification model based on a support vector machine according to the driving style characterization parameters; judging driving styles in a car following state and a lane changing state through a driving style clustering model, and judging the style of a driver by integrating the two driving states; the driving style identification model is used for identifying the driving style of the driver in the following state and the lane changing state. According to the invention, a complete and systematic method can be provided for actively identifying the driving styles of the driver in different scenes, and the method has the advantages of being comprehensive, systematic, accurate in identification, stable and efficient.
