The invention discloses a driver driving behavior analysis system. An additionally arranged measuring module is used for collecting vehicle driving data; measured data is sent to a cloud platform of Internet of Vehicles for calculation. Data is preprocessed and driver driving behaviors are scored. An entropy weight method is used to calculate the weight of each index and calculate the comprehensive score of each driver. Clustering analysis on the scores is made by utilizing a fuzzy C-means algorithm. The clustering result is input into a BP neural network for training, vehicle real-time data is imported into the trained BP neural network, driving behaviors are classified by a BP neural network classifier, the classification result is pro-processed, the classification result is converted into an audio signal, the audio signal is sent to a voice device of the vehicle, and the drivers are reminded by a voice device.
