A robust sliding mode controller for active suspensions of a non-linear half vehicle model is introduced in this study. After designing a non-chattering sliding mode controller, a four degrees of freedom non-linear half car model, which allows wheel hop and includes suspension system with non-linear spring, piecewise linear damper with dry friction, is presented. Then, designed controller is applied to this model in order to evaluate its performance. The results have shown that, the designed controller does not cause any problem in suspension working limits, while increasing the ride comfort of passengers.
