Vehicle Driving Safety Assistant Systems Based on ITS Technologies

Vehicle driving safety assistant systems based on ITS(Intelligent Transportation Systems)technologies can effectively enhance driving safety.The researches on the systems carried out by the State Key Laboratory of Automotive Safety and Energy of Tsinghua University are introduced in this paper.An experimental platform and a prototype vehicle equipped with the driving safety assistant systems have been implemented based on the studies of some key issues i.e. detection and identification technologies of driving environment,investigation of driver behavior and safety distance models,vehicle motion control and system integration etc.The developed vehicle driving safety assistant systems have the function of forward collision warning, safety distance keeping and lane keeping.And a series of experiment have been conducted to evaluate the performances of the driving safety assistant systems.These works are the base of further research on active safety systems based on ITS technologies and industrialization of vehicle driving safety assistant systems.
