Electric vehicle stability control under limit adherence situations in curved paths

In this paper a stability control system for a rear-wheel drive (2WD) Electric Vehicle (EV) with differential traction is proposed. The control strategy ensures vehicle stability in maneuvers near grip limit. Additionally, conditions where the vehicle reaches the limit of cornering stability even using a Direct Yaw Control (DYC) are analyzed. From these bases, a first approach of a brake control that increases vehicle stability region is introduced in order to improve the safety under risky maneuvers.
