The invention discloses a vehicle air spring control method, device and equipment and a storage medium. The method comprises the steps that the axle load of a vehicle is determined based on the trailer mass; when the trailer signal is received, whether the vehicle receives a front road surface state signal or not is judged, and the road surface state signal comprises a road surface protrusion and/or pit signal; when the road surface state signal is received, the collision time of the vehicle is calculated, and the rigidity of the vehicle air spring is adjusted based on the collision time, the axle load, the vehicle speed signal, the road surface state signal and the impact acceleration signal of the front axle; when the road surface state signal is not received, the current driving state of the vehicle is judged, the rigidity of the air spring of the vehicle is adjusted according to the current driving state of the vehicle and the axle load of the vehicle, and the driving states include the acceleration state, the deceleration state, the climbing state and the level road state. The problem that the rear axle of the vehicle shakes when the vehicle drags the trailer is solved.

    本发明公开了一种车辆空气弹簧的控制方法、装置、设备及存储介质,该方法包括步骤:基于拖车质量确定车辆的轴荷;当接收到拖车信号时,判断车辆是否收到前方路面状态信号,其中路面状态信号包括路面凸起和/或凹坑信号;当接收到所述路面状态信号时,计算车辆的撞击时间,并基于撞击时间、轴荷大小、车速信号、路面状态信号和前轴的冲击加速度信号,以对车辆空气弹簧的刚度进行调节;当未接收到所述路面状态信号时,判断车辆当前所处的行驶状态,并通过车辆当前所处的行驶状态以及车辆的轴荷,对车辆空气弹簧的刚度进行调节,其中行驶状态包括:加速度状态、减速度状态、爬坡状态和平路状态。本申请解决了车辆在牵引拖车时,导致的车辆后轴抖动。
