The invention discloses a vehicle, a control method and device for a semi-active suspension of the vehicle and a storage medium. The method comprises the steps that sprung acceleration of a wheel is obtained; when the sprung acceleration is smaller than or equal to a preset acceleration threshold value, the sprung acceleration is processed to obtain harmonic frequency and displacement amplitude; and when the harmonic frequency is within a preset frequency range and the displacement amplitude is greater than a preset amplitude threshold, determining the working mode of the semi-active suspension according to the control instruction. According to the control method, the running working condition of the vehicle can be determined according to the sprung acceleration of the wheels, the corresponding control instruction is selected, the semi-active suspension is controlled according to the control instruction to restrain vibration of a power assembly, and therefore the NVH performance of the vehicle and the riding comfort of a user can be optimized to the maximum extent.

    本发明公开了一种车辆及其半主动悬置的控制方法、装置和存储介质,所述方法包括:获取车轮的簧上加速度;在簧上加速度小于或等于预设加速度阈值时,对簧上加速度进行处理以获得谐波频率和位移幅值;在谐波频率处于预设频率范围内,且位移幅值大于预设幅值阈值时,根据控制指令确定半主动悬置的工作模式。本发明的控制方法能够根据车轮的簧上加速度确定车辆的运行工况,并选择相应的控制指令,并根据控制指令对半主动悬置进行控制,以抑制动力总成的振动,从而可以最大限度优化车辆的NVH性能以及用户乘坐的舒适性。
