The invention discloses a power takeoff fault detection method, device and equipment of a vehicle and a storage medium. The fault detection method comprises the steps that the circuit connection state of the power takeoff electromagnetic valve is detected; when it is detected that the circuit of the power takeoff electromagnetic valve is in the on state, whether the combination input parameters meet preset combination input conditions or not is detected; the combined input parameters comprise output shaft rotating speed information, gear information and hand brake information; when it is detected that the combination input parameter meets the preset combination input condition, the pressure of the gas path is detected; when it is detected that the gas path pressure is larger than or equal to the preset pressure, a feedback signal of the power takeoff combined with a feedback switch is obtained; and when the feedback signal is received, determining that the power takeoff has no fault. By adopting the logic sequence for detection, invalid operation is avoided, the detection time is saved, the problem is more accurately positioned, and the detection efficiency is greatly improved.
本发明公开了一种车辆的取力器故障检测方法、装置、设备以及存储介质。故障检测方法包括:检测取力器电磁阀的电路连接状态;当检测到取力器电磁阀的电路为导通状态时,检测结合输入参数是否满足预设结合输入条件;结合输入参数包括输出轴转速信息、档位信息以及手刹信息;当检测到结合输入参数满足预设结合输入条件时,检测气路的压力;当检测到气路压力大于或等于预设压力时,获取取力器结合反馈开关的反馈信号;当接收到反馈信号时,确定取力器无故障。采用上述的逻辑顺序进行检测,避免无效操作节省检测时间,更准确地定位问题所在,大大提高了检测效率。
