Study On Parameters Design And Simulation For Powertrain System Of Extended-range Electric City Commercial Vehicle Based On Advisor

With the shortage of fossil fuels and urban civilization development, electriccommercial vehicles have been put into operation in parts of the cities in the domestic. Dueto the current battery technology, this kind of vehicles is more suitable for small vehicles,and can’t satisfy the driving distance and the dynamic performance of the medium andheavy commercial vehicles. To develop a kind of extended-range electric commercialvehicles that is not only energy saving and environmental protection as the electric vehicles,but also high-performance as the hybrid vehicles has great practical and economicsignificance.This paper is funded by xi ’an technology bureau project: small electric driver-trainingcars power system matching and optimization design (project number: cx1249④) and thecentral university innovation team project: small plug-in electric field driver-training carskey technology research (project number:2013G3222004). In the first, the paper gives abrief analysis about the structure principle and control strategies of the powertrain system;Then selects the key components, and calculates the parameters of them by using theformula of automobile theory, and determines the powertrain parameter matching scheme,and all those are based on the design indexes; Then in view of the rear wheel drivingsanitation vehicles designed in this paper, does a second development of the rear wheeldrive module based on ADVISOR2002software; At the last, in the ECE+EUDC drivingcycles, simulated the performance of the vehicle through Advisor.The simulation results show that: the maximum speed is82.9km/h; The biggestgradability at the speed of9km/h is29.7%; The acceleration time from0to30km/h is7.1s;The acceleration time from0to50km/h is21.9s; Pure electric limited driving mileage is104.8km. The results prove that the vehicle’s performance conforms to the design indexbasically, which verify the rationality of the matching, and the feasibility of the seconddevelopment of the rear wheel drive module and the powertrain control strategy.
