The invention discloses a commercial vehicle driver driving style identification method based on Internet of Vehicles data. The method comprises the steps: collecting commercial vehicle driving data and vehicle state data in a natural driving scene; carrying out abnormal value detection, missing value filling and elimination, feature extraction and establishment and data dimension reduction on the collected data; clustering the data after data dimension reduction based on a k-means clustering algorithm, and defining a driving type of a driver according to a clustering result; and establishing a driving style identification model based on a random forest algorithm by integrating the driver characteristics and the driving type of the driver, and training and testing the driving style identification model to complete effective identification of the driving style of the commercial vehicle driver. According to the method, the driving style can be comprehensively described, the correlation among the features is reduced by using principal component analysis, the dimensionality reduction optimization of the feature parameters and the accurate and reasonable classification of the sample data are realized, and the high-precision identification of the driving style is realized.
