Abstract: A dynamics model of automotive active anti-roll bar system was proposed to improve the vehicle's driving stability. A PID roll stability controller was designed by establishing auto active defense tilting lever model in the MATLAB/Simulink environment, and the automobile dynamics model was established in CarSim, and the simulation of the system was realized by MATLAB/Simulink and CarSim. The simulation results indicate that the active anti-roll bar system may significantly reduce the roll angles of vehicle body compared with common anti-roll bar. The road tests were also processed, which verified the simulation and approves that the automotive active anti-roll bar system may effectively improve the vehicle's driving stability and safety, as well as the riding comfort.

Key words: active anti roll, anti-roll bar, lateral stability, joint simulation

摘要: 为提高汽车行驶稳定性,建立了汽车主动防侧倾系统的动力学模型,通过在MATLAB/Simulink环境中建立汽车主动防侧倾稳定杆模型,设计了PID侧倾稳定控制器。在CarSim软件中建立了汽车动力学模型,实现了该汽车主动防侧倾系统的MATLAB/Simulink和CarSim的联合仿真。仿真结果表明:与传统横向稳定杆相比,汽车主动防侧倾系统能够明显减小车辆车身的倾角。最后通过实车试验对仿真结果进行了验证,试验结果表明了仿真结果的正确性,证明了汽车主动防侧倾系统能有效提高车辆行驶稳定性和安全性,改善乘坐舒适性。
