应用主动横向稳定器降低汽车侧倾角的研究

Study on Reducing Vehicle Roll Angle by Applying an Active Roll Stabilizer

研究利用主动横向稳定器改善汽车乘坐舒适性和降低汽车侧倾角的可行性。主动横向稳定器置于汽车前、后轴，通过液压控制缸与车架连接。采用转向轮转角前馈控制横向稳定器，可产生克服汽车侧倾运动的反侧倾力矩。实车试验表明：稳态转向或变更行车线时，该系统可明显降低汽车侧倾角和提高汽车的乘坐舒适性。

The subject of this paper is to study the feasibility of reducing vehicle rollangle and improve ride comfort by an active roll stabilizer system. An experimentalvehicle is produced with active roll stabilizer mechanisms consisting of front andrear stabilizers whose one end is connected to the frame by means of each hydraulicactuator. A feed-forward control algorithm for activating the actuators is appliedto generate an anti-roll moment which supresses vehicle roll motion. Vehicle testsshowed considerable reduction of roll angle during steady-state-turning and lane-changing without sacrificing vehicle ride comfort.
