The invention discloses a shock absorber state detection method and device, an automobile and a storage medium. The method comprises steps of determining an inverse transfer function according to preset white noise and a preset multi-body dynamic model; determining an automobile suspension displacement signal and a shock absorber force signal according to the acquired automobile driving data, thepreset multi-body dynamic model and the inverse transfer function; and determining a state of the shock absorber according to the automobile suspension displacement signal and the shock absorber forcesignal. The method is advantaged in that the automobile suspension displacement and the shock absorber force are determined through the inverse transfer function and the multi-body dynamic model, detection of the shock absorber in the whole automobile state is realized, and automobile driving safety is improved.

    本发明公开了一种减振器状态检测方法、装置、车辆和存储介质,其中,该方法包括:根据预设白噪声和预设多体动力学模型确定逆传递函数;根据采集的车辆行驶数据、所述预设多体动力学模型和所述逆传递函数确定车辆悬架位移信号和减振器力信号;根据所述车辆悬架位移信号和所述减振器力信号确定减振器状态。本发明实施例通过逆传递函数和多体动力学模型确定出车辆悬架位移和减振器力,实现了整车状态下减振器的检测,提高了车辆行驶的安全性。
