The accuracy of chassis control for intelligent electric vehicles (IEVs), especially in road-based IEVs control for improving road handling and ride comfort, is a challenging task for the intelligent transport system. Due to the high fatality rate caused by inaccurate road-based control algorithm, how to precisely and effectively chose the reasonable road-based control algorithm become a hot topic in both academia and industry. To address and improve the performance of road handing and ride comfort of IEVs by using semi-active suspension system, an adaptive sliding mode control (ASMC) algorithm based road information is proposed to realize the overall performance for the intelligent vehicle chassis system in the paper. Firstly, the models of road excitation and equivalent hybrid control of a quarter semi-active suspension system are established.
