The invention relates to a multi-working-mode automobile active suspension structure which can achieve stepless adjustment of the height of an automobile body without a height sensor, can adapt to various road conditions and automobile load conditions through four specific working methods, can conveniently adjust the height of the automobile body, can lock the height of the automobile body when needed, and is convenient to use. Therefore, stability is kept and rollover of the vehicle is prevented. Meanwhile, the system has an improved vibration reduction function, vibration between the wheels and the vehicle body can be effectively isolated under the condition that the required control force of the active actuator is not increased, especially in the resonant frequency range of the wheels, and therefore the riding comfort is improved, and the safety of the vehicle is ensured.
本发明涉及多工作模式汽车主动悬架结构,该悬架结构无需高度传感器即可实现车身高度无级调节,通过特定的四种工作方法,能适应各种道路条件和车辆负载情况,方便地对车身高度进行调整,并且在需要时能够锁闭车身高度,以保持稳定并防止车辆侧翻。同时,该系统还应具备改进的减振功能,能够在不增加主动作动器需求控制力的情况下,有效地隔离车轮与车身间的振动,特别是在车轮共振频率范围内,从而提升乘坐舒适性并确保车辆的安全性。
