Development Of SAIBAO Plug-In Hybrid Electric Sedan

Plug-In hybrid electric vehicle is a new type hybrid vehicle derived form the traditionalhybrid vehicles.The salient feature is that it can use the power network to charge up thevehicle battery pack. Its development and application for solving the shortage of resourcesand environmental pollution problem has an important significance It is one of the mostpromising hybrid vehicles by more and more attention of the auto companies,researchinstitutions and governments.This paper is based on the National863project " Hafei Saibao Plug-In Hybrid ElectricVehicle Designation and Development ". It carries out the research work of the vehicleoptimization design and the development of control strategy and other aspects.Firstly, according to the definition and performance index of the vehicle, the overalltechnical scheme design and the selection of power system have completed The assemblystructural scheme design, choice of engines, electric drive assembly system design, batterypack design haved finished.Based on the scheme, the system integration and optimization of the hybrid vehicle havecompleted by the vehicle performance simulation, intensity and toughness and impactsimulation calculation, kinematics simulation analysis.of the front suspension.Secondly, by the control strategy of Saibao Plug-In power system, the simulation analysishave finished.And the different control strategies under the Dominant of motor and enginehave formulated The mode switching rules have givenThis control strategy can satisfy theperformance of SaiBao Plug-In hybrid electric vehicle, and it has the very good rideperformance. It can realize the minimum fuel consumption and emissions, satisfing thecomponent life and reliability requirements simultaneously.Finally, through the vehicle test, the rationality of the vehicle design scheme and thepower system matching has verified, and the application effect of control strategy hasexamined.The paper has finally completed Saibao Plug-In hybrid electric vehicle researchand development work.
