The invention provides a tire pressure monitoring method, device and equipment and a readable storage medium, and the method comprises the steps that in the vehicle running process, the standard rotation speed of a target planetary gear is determined according to the steering wheel rotation angle and the vehicle speed, the target planetary gear is a differential planetary gear of a target driving shaft, the target driving shaft is connected with two target wheels, and the target driving shaft is connected with the two target wheels; the standard rotation speed is the rotation speed of a target planetary gear calibrated under the corresponding steering wheel rotation angle and vehicle speed when the two target vehicle tire pressures are normal; and if the absolute value of the difference between the actual rotation speed of the target planetary gear and the standard rotation speed is greater than the error allowable value, outputting a fault code. According to the application, on the basis of monitoring the tire pressure measurement value of the target wheel, the absolute value of the difference value between the actual rotation speed and the standard rotation speed of the planetary gear is monitored, and the fault code is output under the condition that the absolute value of the difference value is too large, so that the monitoring is more comprehensive, and the problem of tire pressure fault missed judgment caused by signal loss and electromagnetic interference is reduced.

    本申请提供一种胎压监测方法、装置、设备及可读存储介质,该方法包括:在车辆行驶过程中,根据方向盘转角和车速确定目标行星齿轮的标准自转转速,其中,目标行星齿轮为目标驱动轴的差速器行星齿轮,目标驱动轴连接两个目标车轮,标准自转转速为两个目标车轮胎压正常时在对应方向盘转角和车速下标定的目标行星齿轮的自转转速;若目标行星齿轮的实际自转转速与标准自转转速的差值绝对值大于误差允许值,则输出故障码。通过本申请,对于目标车轮在监测胎压测量值的基础上,监测行星齿轮的实际自转转速与标准自转转速的差值绝对值,并在差值绝对值过大的情况下输出故障码,监测更加全面,从而减少信号丢失、电磁干扰导致的胎压故障漏判的问题。
