인-휠 후륜구동 전기자동차의 독립구동 제어를 이용한 선회 성능 향상에 관한 연구

다국어 초록 (Multilingual Abstract)

With the recent advancement of control method and battery technology, the electric vehicle have been researched to replace the conventional vehicle with electric vehicle with the view point of the environmental concerns and energy conservation. An electric vehicle which is equipped with the in-wheel motors has some advantages in terms of control. For example, the different torque which generated by left and right wheels directly can make yaw moment of vehicle with steering angle and it can improve the vehicle stability in cornering. This is called direct yaw moment control. In this paper, we consider a method for improving the stability of In-wheel motored electric vehicle with the direct yaw moment control. We also apply yaw moment observer to estimate the moment generated by the tire and the road contact. Simulation results show that the method can improve the stability of In-wheel motored electric vehicle in cornering.
