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 when a double-cavity air suspension is in a double-cavity mode, the running state change rate of a vehicle is obtained; and if the driving state change rate is larger than the driving state change rate threshold value, the double-cavity air suspension is controlled to be switched from the double-cavity mode to the single-cavity mode. According to the double-cavity air suspension, the rigidity of the double-cavity air suspension can be improved when a vehicle is in a sudden acceleration, sudden deceleration or sudden turning condition, so that the vehicle has better driving stability.

    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:在双腔空气悬架处于双腔模式时,获取车辆的行驶状态变化率;若行驶状态变化率大于行驶状态变化率阈值,控制双腔空气悬架从双腔模式切换至单腔模式。本申请可以在车辆处于急加速、急减速或急转弯情况时,提高双腔空气悬架的刚度,使得车辆具有更好的行驶稳定性。
