The invention provides a shock absorber, an air suspension, a control method of the air suspension, a controller, a control system and an automobile. The shock absorber comprises an oil storage cylinder, a working cylinder, a bottom valve and a piston assembly. The working cylinder is arranged in the oil storage cylinder; the bottom valve is arranged at the bottom of the working cylinder, and the piston assembly is movably installed in the working cylinder and is opposite to the bottom valve. The hydraulic system further comprises a displacement sensor mechanism, and the displacement sensor mechanism is arranged between the piston assembly and the bottom valve and used for detecting displacement signals generated when the piston assembly and the working cylinder move relatively. In the invention, the displacement sensor mechanism can be used for directly measuring the displacement signal corresponding to the displacement change when the piston assembly and the working cylinder move relatively, so that the displacement signal can be derived subsequently to obtain the speed and the acceleration, a height sensor and an acceleration sensor do not need to be additionally arranged for signal detection, and the use requirements are met.

    本发明提供了一种减振器、空气悬架及其控制方法、控制器、控制系统及汽车,该减振器包括贮油缸、工作缸、底阀和活塞组件;所述工作缸设置在所述贮油缸内;所述底阀设置在所述工作缸的底部,所述活塞组件可移动安装在所述工作缸内,与所述底阀相对设置;还包括位移传感器机构,所述位移传感器机构设置在所述活塞组件和所述底阀之间,用于检测所述活塞组件与所述工作缸相对运动时的位移信号。本发明中,通过位移传感器机构可以直接测量活塞组件与工作缸相对运动时的位移变化对应的位移信号,以便后续可对该位移信号进行求导,得到速度和加速度,无需额外设置高度传感器和加速度传感器进行信号检测,满足使用需求。
