The invention relates to the technical field of vehicles, in particular to a semi-active suspension control method, a controller, a vehicle and a storage medium. The semi-active suspension control method comprises the steps that the suspension deformation amount of a vehicle is obtained; and under the condition that it is determined that the suspension deformation amount is larger than a first preset deformation threshold value, target damping of a shock absorber of the suspension is increased to preset damping, the first preset deformation threshold value is smaller than a boundary deformation value, and the boundary deformation value is the suspension deformation amount generated when the suspension initially makes contact with a limiting block. According to the technical scheme, when the deformation amount of the suspension is larger than the first preset deformation threshold value, the target damping of the shock absorber of the suspension is controlled to be increased to the preset damping, even if the damping of the shock absorber is hardened, the deformation amount of the suspension is reduced, and therefore the probability that the suspension collides with the limiting block is reduced, and comfort is improved.

    本公开涉及一种车辆技术领域,具体地,涉及一种半主动悬架控制方法、控制器、车辆及存储介质。该半主动悬架控制方法包括:获取车辆的悬架变形量;在确定所述悬架变形量大于第一预设变形阈值的情况下,增大悬架的减振器的目标阻尼至预设阻尼,其中,所述第一预设变形阈值小于边界变形值,所述边界变形值为悬架初始接触限位块时的悬架变形量。通过上述技术方案,当悬架变形量大于第一预设变形阈值时,通过控制悬架的减振器的目标阻尼增大至预设阻尼,即使减振器的阻尼变硬来减小悬架变形量,从而降低悬架撞击限位块的概率,提高舒适性。
