Abstract

In next-generation electric vehicles, research is being conducted on an in-wheel motor system that directly controls torque by each wheel to improve total cost and driving performance. Accordingly, in this paper, a study was conducted on an algorithm that distributes the torque applied to each wheel in a torque vectoring system applied to an in-wheel motor for driving an electric vehicle. In order to implement a vehicle model that applies actual vehicle characteristic parameters according to vehicle driving and steering, a simulation was conducted in the MATLAB Simulink environment, and it was confirmed that torque distribution was performed according to the proposed algorithm.

차세대 전기자동차에서는 전비 향상 및 주행 성능 개선을 위하여 각 휠에 의해 직접적으로 토크를 제어하는 인 휠 모터 시스템에 대한 연구가 진행되고 있다. 이에 따라 본 논문에서는 전기자동차 구동용 인 휠 모터에 적용되는 토크 벡터링 시스템에서 각 휠에 가해지는 토크를 분배하는 알고리즘에 대한 연구를 수행하였다. 차량의 주행 및 조향에 따른 실제 차량 특성 파라미터를 적용한 차량 모델을 구현하기 위해 MATLAB Simulink 환경에서 시뮬레이션을 진행하였으며 제안된 알고리즘에 따라 토크 분배가 이뤄지는 것을 확인하였다.
