경로정보를 이용한 RE-EV의 배터리 충전량 및 동력기반 주행제어 알고리즘

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 .
