The invention discloses a semi-active suspension control method and device, a storage medium and a vehicle, and the semi-active suspension control method comprises the following steps: detecting the vertical acceleration, the pitch angle speed and the roll angle speed of a vehicle body through an inertial sensor; determining a vehicle body sprung vertical acceleration corresponding to the wheel position according to the vertical acceleration, the pitch angle speed and the roll angle speed, and determining a vehicle body sprung vertical speed corresponding to the wheel position according to the vehicle body sprung vertical acceleration; determining an optimal damping coefficient according to the vehicle body sprung vertical acceleration corresponding to the wheel position and the vehicle body sprung vertical speed corresponding to the wheel position; and controlling the semi-active shock absorber corresponding to the wheel position according to the optimal damping coefficient. Therefore, according to the embodiment of the invention, the control stability of the vehicle can be ensured, meanwhile, the riding comfort of the vehicle is improved, the vehicle can adapt to various different road conditions, the control cost of the vehicle suspension can be reduced, and the user experience is fully improved.

    本发明公开了一种半主动悬架控制方法及控制装置、存储介质及车辆,其中,半主动悬架控制方法包括以下步骤:通过惯性传感器检测车身的垂向加速度、俯仰角速度和侧倾角速度;根据垂向加速度、俯仰角速度和侧倾角速度确定车轮位置对应的车身簧上垂向加速度,并根据车身簧上垂向加速度确定车轮位置对应的车身簧上垂向速度;根据车轮位置对应的车身簧上垂向加速度和车轮位置对应的车身簧上垂向速度确定最佳阻尼系数;根据最佳阻尼系数对车轮位置对应的半主动减振器进行控制。由此,本实施例能够保证车辆操纵稳定性的同时,提高车辆的乘坐舒适性,使车辆能够适应多种不同的路况,并且,还可以降低车辆悬架的控制成本,充分提高用户体验。
