Research On Operating Vehicle Drivers’ Driving Behavior Economy Evaluation And Performance Improvement

With the rapid growth of economy and booming development of china’s auto market,the number of cars is increasing but brings more and more energy problems.The research of energy conservation and emissions reduction are increasingly significant.The drivers are the very important part of the “person-vehicle-road” system and the driving behavior is directly related to vehicle driving conditions and fuel consumption.Operating vehicles,though less in proportion of number,but consume most of the refined oil products cost by vehicles.Therefore,it’s essential to research the driving behavior of the operating vehicles drivers.To this end,this paper first analyses the vehicle fuel economy to extract the main indicators affecting the economy driving behavior.Driving behavior economic evaluation index evaluation model is set up and calibrate the parameters needed in the process of evaluation;Through the establishment of the indicators of fuel consumption model,to determine the influence degree of each index of fuel consumption and to determine the score of each index and total score;Write the visual drivers driving economic evaluation program and then verify and analyze the program.Finally,the paper summaries and forecast the insufficiency and the research direction of this paper.Overview the research background to illustrate the research significance of the operating vehicle driver driving behavior economic evaluation and the role of operating vehicles in our country and analyzes the research status of driving behavior at home and abroad.This paper also summarizes the existing driving behavior evaluation system.Based on the theory of vehicle fuel economy analysis,this paper sum up the vehicles running state which improving the vehicle fuel economy.Through the fuel-efficient vehicles running state,generalize the energy-saving vehicle driving behavior and make the behavior as the evaluation index of the driver driving economy,and the driving economy index evaluation method were determined.According to the actual data of driving behavior to set up the evaluation model parameters.This paper introduces the source of data used and acquisition methods,and the method of data processing.For those data which can’t be collected.We use the existing data for calibration by statistic and analysis.This paper present a comprehensive score method based on driving behaviors.We use SPSS to analyze the experiment data to simulate the fuel consumption model based on each driving behaviors’ vehicle fuel economic index.The effect of different driving behavior on fuel consumption is determined by the fuel consumption model of each index and also the comprehensive score method is established based on the fuel consumption model.MATLAB programming is used to visualize the comprehensive score method.This paper introduced the framework and function of the driving behavior economic evaluation program.Then score and analyze the fuel consumption conducted by different drivers on the same sample operating vehicle and provide optimizing advice for driving economy to different driving behaviors.
