Research On Parameter Matching Of Parallel Hybrid Electric Vehicle

At present,the two major problems faced by the sustainable development of the world auto industry are the increasingly stringent emission requirements and energy shortage,low emissions and low fuel consumption is an important direction for the development of Automotive Technology in twenty-first Century.Hybrid electric vehicle(HEV)is a new generation of clean vehicles with low pollution and low fuel consumption characteristics.From the vehicle efficiency,power performance,mileage and other aspects of consideration,parallel hybrid vehicles more suitable for urban operating conditions.The author has done the following research work on the parameters matching of the power system of parallel hybrid electric vehicle:(1)This paper introduces three main driving structures of hybrid electric vehicles: series,parallel and hybrid.The advantages and disadvantages of various types of drive types are compared and summarized.(2)The selection of components of parallel hybrid powertrain system is studied,the energy storage element,engine,motor and transmission scheme selection.(3)Aiming at a car factory 10.5 meters bus matching YCHPT hybrid system were dynamic parameters matching calculation,to determine the optimal scheme.(4)Through the vehicle of real vehicle validation scheme.The results show that determine the power system parameters matching Yuchai parallel hybrid system in vehicle power and economy better in line with the design requirements.
