In this paper, a CVT system model was developed including the shift dynamics and clamping force characteristics to investigate the powertrain components loss for a Parallel-HEV equipped with CVT. The loss model was developed from experimental data considering the line pressure, CVT input speed, input torque, and gear ratio. Using the developed CVT system model, a vehicle performance simulator was constructed. For 505, UDDS and HWFET driving cycle, the CVT loss was analyzed with gear, clutch, etc. It was found that the CVT loss takes the largest part in the powertrain loss except for the driving resistance.

In this paper, a dual clutch transmission(DCT) shift performance simulator were developed to evaluate the shift quality using MATLAB/Simulink and SimDriveline. Dynamic models of the DCT were obtained including synchronizer, gear fork actuator system, and clutch Based on the dynamic models, a DCT shift performance simulator was developed. Test and simulation results were compared to verify the DCT shift performance simulator. It was found that the test and simulation results were good agreement, and it is expected that developed simulator can be used to improve the shift quality of the DCT.

In this study, a route information based control algorithm was developed for range-extended electric vehicle (RE-EV). The algorithm estimates demanded vehicle power and SOC charging amount using the route information and vehicle dynamic model. In addition, a threshold vehicle demanded power was obtained to improve the energy conversion efficiency by transmitting the power from the range extender to the driving motor directly. To evaluate the performance of the algorithm, a RE-EV performance simulator was developed. It was found that fuel consumption can be reduced compared with the existing control algorithm by the proposed algorithm .
