- Abstract:
- A pure electric vehicle with a fixed speed ratio was changed into two gear transmission scheme.Thematching method of main parameters for powertrain components was analyzed based on specifications of vehicleperformance.In order to prove that the parameter matching is reasonable,the dynamic shift schedule and the e-conomy shift schedule were formulated.Through the vehicle performance simulation platform which was estab-lished under Matlab/Simulink,the vehicle dynamic performance and the driving range under the different shiftscneaue were simuLalea. Ine simuaion resuIs snow nat ne parameter maicnng is reasonane,ana tne powerperformance and the driving range can meet the design requirements.The driving range of the NEDC conditionunder economy shift schedule is 0.14% higher than under the dynamic shift schedule. The acceleration time in100km under the dynamic shift schedule decreased by 6.02% than under the economy shift schedule.
