Research On Transient Fault Driving Behavior Based On Driver Model

With the rapid development of information technology and the increasing number of car ownership,driving safety issues have gradually attracted people's attention.Especially in the turn or change the operation of high-speed vehicles,the accident rate,far higher than the car in a straight line conditions of the situation.Therefore,to carry out horizontal dangerous driving behavior identification research,to ensure the safety of vehicle horizontal driving,to improve the vehicle lateral active safety and operational stability,to prevent the driver from the horizontal dangerous driving behavior caused by vehicle rollover,slip and other serious traffic accidents And the promotion of the development of contemporary road transport system has important practical value.This paper relies on the Chongqing Municipal Science and Technology Commission scientific research project "vehicle horizontal driving behavior identification and vehicle interaction active safety control research"(Grant No: cstc2014 jcyj A6007).Based on the current situation of domestic and foreign research,this paper analyzes the driver and vehicle state parameters which characterize the driver 's horizontal driving behavior,and constructs the comprehensive evaluation model of horizontal dangerous driving behavior.The specific research contents are as follows:(1)In this paper,the driver's driving behavior information and vehicle feedback information are studied from the perspective of the driver's lateral driving ability and the capacity of the system driving task demand.The center-of-mass,yaw rate,lateral acceleration,lateral velocity,Lateral displacement and so on can describe the driver's horizontal driving behavior of the relevant factors,and describes the horizontal dangerous driving behavior identification of the basic theoretical basis and steps.(2)Based on the optimal curvature driver model,the lateral velocity error correction link is introduced,and the fuzzy controller is constructed by fuzzy-PID control.Based on the vehicle system dynamics,the vehicle-vehicle model is improved by identifying the vehicle parameters under the two-degree-of-freedom vehicle model.Based on the model,the center-to-side angle,the lateral velocity,the lateral acceleration,Speed,lateral displacement and other influencing factors were simulated and analyzed to explore the changes of vehicle stability state characteristics under transverse driving behavior(3)Based on the classification of the safety factors of each characterization factor,the fuzzy comprehensive evaluation method is used to analyze the driver's road sensation,the track accuracy of the vehicle,the risk of vehicle rollover,the driver's lateral driving burden and the risk of vehicle slip This paper evaluates the indicators related to the horizontal driving behavior,and uses the "1-9 scale method" to construct a comprehensive evaluation model of the horizontal dangerous driving behavior recognition based on the least squares method,and completes the horizontal hazard under different vehicle speeds Analysis on the Evaluation Indexes of Comprehensive Evaluation Model of Driving Behavior.The initial realization of the horizontal dangerous driving behavior identification.In this paper,based on the lateral velocity fuzzy-PID control of the driver model of the horizontal dangerous driving behavior comprehensive evaluation method,from the perspective of data analysis,objective and scientific analysis of the horizontal dangerous driving behavior for The development of vehicle early warning control system provides important reference value.
