인휠모터 전기차량의 성능 개선 연구

초록

In-wheel motor electric vehicle which does not need power train such as constant velocity joint and propeller shaft is being used to drive in urban area. However it can be used only in urban area. However its maximum velocity is limited under 60km/h in the area. Because when velocity of vehicle is high, the performance becomes low. So it is needed to develop a method that improves performance of vehicle. In this paper In-wheel motor electric vehicle model is made by using AFPM(Axial Flux Permanent Magnet) and planetary gear is used to change gear ratio to improve the performance of regenerative braking. If the velocity is high, small gear ratio is used to improve fuel efficiency, and if vehicle is braking, large gear ratio is used to improve the performance of regenerative braking. In this paper AVL Cruise is used to confirm the improvement of performance.
