The invention discloses an air spring overpressure diagnosis method, device and equipment and a computer readable storage medium, and relates to the technical field of vehicle diagnos.The air spring overpressure diagnosis method includes the steps that in the air inflation process of a target air spring, when it is detected that a first pressure value collected by a pressure sensor in an air spring system is larger than a preset overpressure threshold value, the air inflation action of the target air spring is controlled to be stopped; the pressure release valve is controlled to be in an open state, the pressure release valve is closed after a preset opening duration is continued, and the target air spring distribution valve is controlled to be in an open state to obtain a second pressure value; and if it is detected that the second pressure value is not smaller than a preset first pressure threshold value, it is judged that the target air spring is in an overpressure state, and the first pressure threshold value is smaller than the overpressure threshold value. Therefore, the air spring overpressure diagnosis method and device can effectively eliminate the influence of abnormal working of the air spring distribution valve, the air spring pressure retaining valve and the like on the air spring overpressure diagnosis, so as to realize the accurate diagnosis of the air spring overpressure.

    一种空簧过压诊断方法、装置、设备及计算机可读存储介质,涉及车辆诊断技术领域,包括在目标空簧充气过程中,当检测到空簧系统中压力传感器所采集到的第一压力值大于预设的过压阈值时,控制停止目标空簧的充气动作;控制泄压阀处于打开状态,待持续预设打开时长后关闭泄压阀,并控制目标空簧分配阀处于打开状态,以获取第二压力值;若检测到所述第二压力值不小于预设的第一压力阈值,则判定所述目标空簧处于过压状态,其中,所述第一压力阈值小于所述过压阈值。可见,通过本申请能够有效排除空簧分配阀和空簧保压阀等工作异常对空簧过压诊断的影响,以实现空簧过压的准确诊断。
