摘要：

Stability control system is a part of active safety systems in vehicles, which is designed to control the vehicles' dynamic motion in emergency manoeuvres. In present study, modelling and simulation of a 4 degrees of freedom (4DOFs) passive suspension system initially is considered and then in order to improve the efficiency of controlling system, a new suspension system with 8DOFs by adding masses to sprung and unsprung parts of suspension system and using hybrid semi-active damper is designed. To investigate the effect of DOF on the controller performance, sliding mode controller (SMC) for models with 8DOFs are designed in MATLAB and controller performances are studied. Also, numerical results from a typical vehicle that is simulated in CarSim are the input for MATLAB simulation. Investigations show that increasing degrees of freedom accompany with applying hybrid semi-active damper lead to better stability and good handling characteristics of vehicle.
