Research On Driver's Physiological Reaction During Braking

Transport is one of the essential conditions to people's daily travel.Residents travel mode has undergone enormous changes as China's economic development.Private car has become the most preferred way for urban residents travel.Last few years,the scope of the popularity of private cars in the country is becoming more and more widely.The emergence of automobiles has made people's travel more comfortable,but this also brings lots of problems.Traffic congestion has become more common in our country,more traffic accidents take place everyday.These have caused huge losses to people's personal property safety.At present,China motor vehicle drivers has increased to 280 million,in these people,whose driving experience is less than one year are 36.13 million people.As lack of awareness of safe driving and abiding the laws,new drivers will cause more traffic accidents.As a giant country in automobile product and consumption,China suffers increasingly severe traffic pressure.Traffic safety is a concern in research for many experts and scholars.Vehicle driving safety is important to solve the traffic safety as a breakthrough.In urban road environment,traffic accidents usually take place in the low-speed running.These accidents are caused by driver error,in the low-speed driving,driver's awareness of risk is low,braking is not timely,error braking action will increase the chances of traffic accidents.So with the research on driver braking behavior in urban road environment,and the analysis of driver behavior and physiological reactions during braking,we can get driver's state in this driving environment.This will provide support for research on traffic safety and driving assistant system technology.Based on driver's physiological reactions and real vehicle test,we can get driver's physiological parameters and vehicle parameters.These datas are divided into three groups,driving straight,turning left and turning right.Use vehicle speed and brake pedal force as the data which can reflect braking process.,then make analysis with emg data and eda data.In this article,driver's emg and eda response is researched during braking in urban road environment.The main research contents are following.1.Based on physiological reaction,research driver's behavioral responses in taking braking with a new idea.Collect five drivers' 100 groups of driving data,capture driving video when driving the vehicle.Based on the driving speed,make comparative analysis.2.With the requirements of studies,use VBOX which based on RLVB20SL,brake pedal force acquisition equipment,steerangle acquisition equipment,make unified data output with RLVBADC03 equipment.Collect driver's EMG and EDA data with CAPTIV equipment.Make the time synchronization in these datas with timer.3.Make graph with the data of speed,brake pedal force and EMG.Get the driver's brake reaction time,including the time when foot leaves the accelerator to reach the brake pedal,and the time when the driver hit brake pedal to stable brake pedal force is gotten.Analyse the two time with data in driving straight,turning left and turning right.Analyse the relationship between emg,speed and brake pedal force.4.Analyse the characteristics of EDA between different drivers with vehicle parameters and EDA data.Research on the EDA reaction when the drivers take braking.
