Abstract


Frequent the basic freeway rear-end accident , the accident suffered serious losses , the rear-end collision warning the basic freeway motor vehicle driver with the car driving to conduct research and to evaluate the driver with the car driving safety , will be able to effectively prevent and reduce highway rear-end accidents , in order to improve the driver with the safety and speed of the car with high-speed control provide a theoretical basis , and far-reaching significance to people's lives and property safety . The same time , the results of this study will be directly applied to the safety evaluation of driver behavior , and provide a reference for the the driving simulation safety testing system development . First, from the point of view of the driver characteristics , vehicle characteristics , road characteristics and traffic flow characteristics on the highway with the car behavior influencing factors were analyzed. And then in the car with the car driving safety basis of the analysis , based on classical Newtonian mechanics , were established criticality safety distance between vehicles in the nine state model , basic safe distance between vehicles model and full safety car away from the model , and the highway car factors Affecting experience calibration values ??, the rear-end collision warning model has been simplified . The same time, the basis of the safe distance between vehicles model , the establishment of a driver's car with safety evaluation model . Finally, we realized early warning simulation process and methods to determine the practical car warning and driver car following safety evaluation program , and the use of driving simulation system , model car rear-end collision warning and driver with car driving safety evaluation model used in the simulation platform to verify the validity . The results show that the driver of the vehicle speed control affect the car with the car of the main factors driving safety . At the same time , can be identified as the main factors affect the effectiveness of the early warning model model coefficients . By selecting the proper model coefficients to determine an effective early warning program , and alarm suppression and correction , and is the basis of effective early warning and assessment of the car with the car driving . The driving simulation experimental results show that the early warning and assessment model of effective , reliable, and can be used for the driver with the car safety inspection .
