Self-positioning device and method of tire pressure monitoring sensor, automobile key and medium

Abstract

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.

Description

technical field [0001] The present application relates to the technical field of vehicles, and in particular, to a self-positioning device, method, car key and medium of a tire pressure monitoring sensor. Background technique [0002] The main function of vehicle active safety is to monitor and avoid the possibility of vehicle loss of control and traffic accidents, improve vehicle driving stability, and prevent accidents. The tire pressure loss of the car may cause the vehicle to lose control or even roll over during the driving process in severe cases. The Tire Pressure Monitoring System (TPMS) is mainly used to monitor the tire pressure and temperature. High temperature and other dangerous conditions are warned in advance to ensure driving safety. After starting the car engine, after the tire pressure sensor in each tire detects the tire pressure, temperature and other data, it encodes the data into a specified format and sends it to the body controller (Body Control Modu...

AI Technical Summary

Problems solved by technology

[0005] This application provides a tire pressure monitoring sensor self-positioning device, method, car key and medium to solve the problem of reading four tire inner sensor IDs (Identity document, ID card identification number) on the vehicle assembly line in the related art, and then Burning into the BCM, it is prone to misoperations that lead to errors in the sensor ID written to the BCM, tire position errors that cannot be corresponded to, and even recall problems in the after-sales stage, improve positioning accuracy, and reduce recalls in the after-sales stage caused by misoperations on the assembly line
