Research On Driving Conditions Of Tianjin Hybrid Bus

Along with our country developing and input to the public transport vehicles,hybrid bus has a widespread application in the actual operation process,so the research of running condition of bus is more important.Based on the driving route of tianjin 600 bus,this paper selects a typical road section of tianjin city to carry out the road condition.The new energy application development project of tianjin bus will also be developed and designed for the first time on the 600 bus.In this paper,through a set of on-board real-time monitoring system for real-time acquisition of 600 bus vehicle parameters under normal operation,600 bus driving condition in tianjin do detailed investigation and analysis,finally it is concluded that a 600 bus based on tianjin actual speed,acceleration time,deceleration time,uniform time,idle time the number of criteria such as typical driving cycle.First,for data collection,this paper introduces the background of running condition,related concept,classification method and abide by the principle of building process,for the establishment of the city bus driving cycle diagram provides the theoretical basis,and several typical countries and regions(the United States,Europe and Japan)to develop and use of running condition of several representative made a more comprehensive introduction;Then,the research and comparison of their respective characteristics are carried out.Finally,a few conclusions are drawn.Secondly,after establishing the overall plan of constructing the driving conditions of the 600 buses in tianjin city,the GPRS wireless communication module is adopted to obtain the data that reflects the real driving condition of the vehicle.And piecewise analysis was carried out on the collected data,the velocity in peak and off-peak period,and the comprehensive period of statistical analysis of the percentage and then select some typical working condition of synthesis,and then compared with the overall condition analysis.Will select 11 feature parameter error comparison as a benchmark,respectively will fit in the 1180 s,tianjin 600 segments of the effective movement to calculate bus driving cycle,using the modal gasoline-fuelled vehicles characteristics numerical optimization again by FCM clustering method for effective analysis and verification.Finally,using the related principles of statistics,sum up the 600 bus driving laws,accordingly,build a condition of cyclic graph analysis method,and according to this method to establish the cyclic graph of tianjin 600 bus driving cycle.The speed-time curves of several of the most representative stations were selected in the driving route to analyze the traffic conditions and road design conditions of the bus routes.According to the results of the above analysis,the paper puts forward some reasonable requirements and Suggestions to tianjin 600 buses.
