Abstract：Electric vehicle`s longitudinal control model is non-linear and vulnerable to external environment factors.This paper designes a sliding mode controller to improve the control system`s robustness.What`s more, this fuzzy controller reduces the inherent chattering of the sliding mode control method by adjusting the parameters of the switch function instantaneity.Compare with the common sliding mode control method, this paper`s controller is more stable, for this paper`s controller decreases the frequency of the control system`s input effectively.Simulation results show that system tracks the desired speed accurately and rapidly, while the system has strong robustness to parameter perturbation and external disturbances.
