Abstract(E) | With the motivation of the enhancement of the controllability of electric vehicles (EVs), this study proposes an effective slip ratio control method of EVs that maximizes cornering force of each wheel. A variable slip ratio limiter (VSRL) is constructed based on brush tire model in order to increase the lateral force of tire. However, a conventional VSRL did not necessarily maximize cornering force since it did not consider the effect of steering angle and cornering drag force. The new VSRL is proposed here with a basic experimental verification using a real EV. The results confirm the increase of both yaw rate and lateral acceleration while turning at the same speed. |
