A sliding mode control strategy for a distributed driving electric vehicle

Active safety is a critical issue for vehicles. In this paper a distributed driving electric vehicle including two electric motors was studied. To improve the longitudinal dynamic performance in driving emergency, a sliding model control algorithm which is worked on the front-wheels is employed. It can achieve anti-slip control through keeping the wheels' slip ratios below 20%. The sliding mode control strategy was simulated on the joint roads. Simulation results show that the proposed control approach is reasonable and can apply to different low-adhesion road surfaces.
