Abstract

Abstract

In order to improve the stability of vehicle's anti-overturn in curve driving and sudden turning at high speeds, which affect vehicle driving safety, this paper put forward the semi-active suspension system (SASS) to replace the passive suspension system with poor anti-overturn stability, established the models of SASS and control system. Its suspension damping force was adjust by controller in order to improve the vibration stability of vehicle. Simulation results show that the effective roll angle of vehicle with SASS decreases by 60.9% in sudden turning at high speed, the effective roll angle acceleration and anti-overturn factor decrease by 64.6% and 35.2% respectively. The results show that the SASS can effectively reduce the roll angle and roll angle acceleration in nonlinear driving, improve the anti-overturn stability. SASS is a reasonable solution to improve vehicle safety in nonlinear driving.
