提高车辆转向稳定性的车身主动侧倾控制研究
Improve vehicle steering stability via active roll control
摘要
Abstract
The tilting of vehicle towards the outside of the curve caused by high-speed turning will lead to a roll-over accident in severe cases.To address this problem,the Active Roll Control(ARC)of the vehicle body was stud-ied to improve the vehicle steering stability.A vehicle dynamic model with six Degrees of Freedom(DOFs)was es-tablished considering both yaw and roll motions.Then,the desired vehicle roll angle was determined,and an active roll controller was designed to make the actual roll angle approach the desired roll angle.Finally,simulations were carried out to obtain vehicle body roll angles,acceleration perceived by occupants and the lateral load transfer rates,and investigate the power consumption of active suspension for roll control as well as the dynamic deflection of the suspension due to the active roll under different driving conditions.The results show that the ARC can make the ac-tual roll angle rapidly approach the desired roll angle,and still ensure driving stability under complex driving condi-tions;the ARC reduces the peak value of the suspension dynamic deflection,and decreases the lateral acceleration perceived by occupants and the lateral load transfer to zero;the low power consumption of the active suspension for roll control ensures the vehicle's economic performance.关键词
