The invention provides a suspension height adjusting method, device and equipment of a cargo-carrying commercial vehicle and a storage medium, and particularly relates to the technical field of suspension adjustment of cargo-carrying commercial vehicles. According to the method, the actual height of the air suspension is obtained through a height sensor periodically. And according to the actual height and the target height, the height difference is determined, and the operation state of the electromagnetic valve is determined according to the height difference. And according to the running state, a corresponding target duty ratio is selected, and according to the target duty ratio, the electromagnetic valve is controlled to run in the running state, so that the air spring is inflated and deflated. According to the method, the duty ratio is calculated through the value of the current actual height fed back by the height sensor and the actual height of the previous period, the situation that in the air suspension control process, due to the fact that the duty ratio is inconsistent with the actual regulation and control requirement, the inflation and deflation process is unstable is avoided, the air spring can be lifted at the stable speed through the method, and the stability of the air suspension is improved. And the robustness is enhanced.

    本申请提供一种载货商用车的悬架高度调整方法、装置、设备和存储介质,具体涉及载货商用车的悬架调节技术领域。该方法按照周期通过高度传感器获取空气悬架的实际高度。根据实际高度和目标高度,确定高度差,并根据高度差,确定电磁阀的运行状态。根据运行状态,选择对应的目标占空比,并按照目标占空比,控制电磁阀在运行状态下运行,以对空气弹簧进行充放气处理。该方法通过高度传感器反馈的目前实际高度与前周期的实际高度的值来计算占空比,避免空气悬架控制过程中因占空比与实际调控要求不一致,而导致的充放气过程的不平稳,通过该方法可以使空气弹簧以平稳的速度进行提升,增强鲁棒性。
