Research on User Vehicle Operation Regularity

摘要

Engineering Questions and Research Objective During vehicle development, engineers often set vehicle design targets based on the reports from market investigation, benchmarking, testing or users' feedbacks. However, such reports, which can not provide quantitative, accurate data on vehicle running information, may cause over-design or insufficient design problems. In this paper, a method on how to collect vehicle running information and analyze user operation habits and cars' running regularity is researched in order to solve the problems. Methodology By investigating engineers' requirements and vehicle specifications, the information collection scheme was determined and analysis arithmetic was designed. Secondly, according to collection requirements analysis and network capacity analysis, the on-board information collection device was produced and background service system was built. Thirdly, database was established using the collected vehicle running information. Fourthly, vehicle operation regularity and user driving habits was found out by submitting enormous data to arithmetic program and analyzing it. Results Vehicle running analysis model was made and database was built. Analysis results provide the basis for vehicle top-down design and design improvement. Limitations of this study Due to the limitation number of vehicle samples, the analysis results represent only part of vehicle running information. What does the paper offer that is new in the field: The device can comprehensively collect signals from CAN/LIN BUS and from various sensors. The acquired data can be packed and uploaded to sever via 3G network. Conclusion This study proved the methodology of vehicle running information collection and data process is feasible. The device could not only collect and store plenty of data, but also upload the data files to sever. By using the arithmetic program, data could be analyzed. The analysis results of user operation habits and vehicle running regularity provide important references for vehicle design. For long-term work, consistent and extensive collection work needs to be done in order to acquire more accurate statistical data.
