The invention provides a double-cavity air suspension control method and a double-cavity air suspension control device. The double-cavity air suspension comprises a single-cavity mode and a double-cavity mode. The rigidity of the double-cavity air suspension in the single-cavity mode is higher than that of the double-cavity air suspension in the double-cavity mode. The double-cavity air suspension control method comprises the steps that the vertical acceleration of wheels of a vehicle is obtained; according to the vertical acceleration, the roughness of the road surface on which the vehicle runs is determined; and if the roughness is larger than the roughness threshold value, the double-cavity air suspension is controlled to be switched from the single-cavity mode to the double-cavity mode. According to the double-cavity air suspension, when a vehicle runs on a rough road surface, the rigidity of the double-cavity air suspension can be reduced, so that the vehicle has better riding comfort.

    本申请提供一种双腔空气悬架控制方法和双腔空气悬架控制装置。双腔空气悬架包括单腔模式和双腔模式。双腔空气悬架在单腔模式下的刚度高于在双腔模式下的刚度。双腔空气悬架控制方法包括:获取车辆的车轮的垂向加速度;根据垂向加速度,确定车辆行驶的路面的粗糙度;若粗糙度大于粗糙度阈值,控制双腔空气悬架从单腔模式切换至双腔模式。本申请可以在车辆行驶于粗糙路面时,降低双腔空气悬架的刚度,使得车辆具有更好的乘坐舒适性。
