To solve the problem of single driving style was considered and unclear driving characteristics of different car-following styles in the existing intelligent car-following assistant system, this paper selected the car-following segments of drivers with different styles by natural driving trials, and 225 car-following segments were classified by K-means, which were divided into three categories: conservative, moderate and aggressive. Then, the THW (Time Headway), the opening of the accelerator pedal, TTC, the velocity of ego-vehicle and preceding vehicle were selected to analyze the driving characteristics of drivers under three different car-following styles. It is found that the velocity of conservative is less affected by the front vehicle, and the THW is distributed between 2-3s, also the opening of the accelerator pedal is basically kept below 40%, and the absolute value of TTC is large, so the collision risk is low; the velocity of aggressive is greatly affected by the front vehicle, and they are used to keeping a close following distance to follow the front vehicle, and their THW is distributed in 0.5-1.5s, also the absolute value of TTC is small, so the risk of car-following collision is high; The driver’s driving characteristics of the moderate lie between the two.
