The invention relates to a self-positioning device and method of a tire pressure monitoring sensor, an automobile key and a medium. The device comprises a receiving module, a signal processing module and a control module, wherein the receiving module is used for receiving radio frequency field intensity of one or more tire pressure sensors of an automobile through the automobile key; the identification module is used for identifying the actual position of each tire pressure sensor according to the radio frequency field intensity of each tire pressure sensor on the basis of the current position of the automobile key; the sending module is used for generating corresponding positioning information according to the actual position of each tire pressure sensor and sending the positioning information to an automobile body control module BCM of the automobile. Therefore, the problems that the sensor IDs in the four tires are read on the whole vehicle assembly line and then burnt into the BCM, misoperation is likely to occur, so that the sensor IDs written into the BCM are wrong, the positions of the tires are wrong and cannot correspond, and even recall in the after-sales stage is needed are solved, the positioning precision is improved, and the recall problem in the after-sales stage caused by misoperation on the assembly line is reduced.

    本申请涉及一种胎压监测传感器的自定位装置、方法、汽车钥匙及介质,装置包括:接收模块用于由汽车钥匙接收车辆的一个或多个胎压传感器的射频场强强度;识别模块用于基于所述汽车钥匙的当前所处位置,根据每个胎压传感器的射频场强强度识别所述每个胎压传感器的实际位置;发送模块用于根据所述每个胎压传感器的实际位置生成对应的定位信息,并发送所述定位信息至所述车辆的汽车车身控制模块BCM。由此,解决了在整车装配线上读取4个轮胎内传感器ID,再烧录进入BCM内,容易出现误操作导致写入BCM的传感器ID出错,轮胎位置出错无法对应,甚至需要售后阶段召回的问题,提高定位精度,减少因为装配线上误操作导致售后阶段召回问题。
