英文摘要：

A safety distance mathematical model of vehicle longitudinal is estabished based on modeling method of driving characteristic and traditional kinetic analysis of safety distance. Through the real-time detection of driving behavior, the driving characteristics identification model, the driving characteristics , vehicle, road, environment factor and other factors are integrated into the mathematical mode. By calculating and comparing the mathematical model is proven to be higher accuracy and real-time, which has a high application value in vehicle collision avoidance systems research.
