    摘要:

    在分別建立轉(zhuǎn)向、懸架和輪胎數(shù)學(xué)模型的基礎(chǔ)上,理論推導(dǎo)出橫擺角速度與側(cè)傾角的相互關(guān)系,分析了角階躍輸入下路面附著系數(shù)和車速對轉(zhuǎn)向的影響,刻畫了不同車速和前輪轉(zhuǎn)角下橫擺角速度與側(cè)傾角的變化過程,通過分析總結(jié)出兩者之間的穩(wěn)態(tài)值變化規(guī)律。仿真和試驗(yàn)結(jié)果表明,試驗(yàn)與仿真的結(jié)果相吻合,驗(yàn)證了仿真的正確性, 為側(cè)向和垂向動力學(xué)的集成控制研究提供了理論參考。

    Abstract:

    The mathematical models of the steering, suspension and tires were established, and based on those models, the relationship between yaw velocity and heeling angle was deduced theoretically. In addition, the influence of road surface adhesion and speed on angle input was analyzed. At the same time, the change of yaw velocity and heeling angle were recorded under the different speeds and front wheel corners. Through detailed analysis the change rule of the steady state value was summarized. At last, the result of simulation and experiment showed the correctness of the simulation and the models, and provided a theoretical reference for the lateral and vertical dynamics integrated control. The proposed research ensures the driving safety, enhances the handling stability, and improves the ride comfort.
