The invention relates to a control method and device of a shock absorber, a vehicle and a storage medium. The method comprises the steps that an IMU signal of the current vehicle, the damping coefficient of the shock absorber, the rigidity of a spiral spring and vehicle body and suspension displacement of a target vehicle body position are obtained; calculating vehicle body vertical vibration acceleration of at least one vehicle body position of the current vehicle according to the IMU signal, and calculating relative speed of a shock absorber of at least one vehicle body position according to the IMU signal, a shock absorber damping coefficient, spiral spring stiffness and vehicle body and suspension displacement of the target vehicle body position; and according to the vehicle body vertical vibration acceleration of the at least one vehicle body position and the relative speed of the at least one vehicle body position shock absorber, a control strategy of each shock absorber is determined, and each shock absorber is controlled according to the control strategy of each shock absorber. Therefore, the problem that the cost of configuring the CDC shock absorber on a low-end vehicle model is high is solved, the cost is reduced, meanwhile, the system failure rate is reduced, and the product competitiveness of the vehicle is improved.

    本申请涉及一种减振器的控制方法、装置、车辆及存储介质,方法包括:获取当前车辆的惯性测量单元IMU信号、减振器阻尼系数、螺旋弹簧刚度和目标车身位置的车身和悬架位移;根据IMU信号计算当前车辆至少一个车身位置的车身垂向振动加速度,并根据IMU信号、减振器阻尼系数、螺旋弹簧刚度和目标车身位置的车身和悬架位移计算至少一个车身位置的减振器的相对速度;根据至少一个车身位置的车身垂向振动加速度和至少一个车身位置减振器的相对速度确定每个减振器的控制策略,并根据每个减振器的控制策略对每个减振器进行控制。由此,解决了低端车型配置CDC减振器成本较高的问题,降低成本,同时减低系统故障率,提升车辆的产品竞争力。
