An intelligent tire automatic positioning system and setting method

Abstract

The invention provides an intelligent tire automatic positioning system and a setting method. The intelligent tire automatic positioning system includes a PEPS system and an intelligent tire system. The PEPS system has a PEPS control unit and a plurality of low-frequency transmitters controlled by the PEPS control unit. The intelligent tire system has The tire control unit and multiple sensors distributed in the corresponding tires. The PEPS control unit controls multiple low-frequency transmitters to send low-frequency signals. The sensors receive various low-frequency signals. The sensors extract various low-frequency signal features and send radio frequency signals to the tire control unit for response. The data corresponding to the signal characteristics, so as to calculate and judge the wheel position of the sensor. The intelligent tire automatic positioning setting method includes a sensor execution step, a positioning calculation step and a positioning setting step. The invention combines the PEPS system with the intelligent tire system to realize accurate calculation and judgment of the wheel position of the sensor before the vehicle is started, so that the vehicle can be automatically positioned in a static state to ensure the safety of the vehicle.

Description

technical field [0001] The invention belongs to the technical field of vehicle tire positioning, and in particular relates to an intelligent tire automatic positioning system and a setting method. Background technique [0002] The smart tire system is a method that monitors the parameters of vehicle tires, such as pressure, temperature, acceleration, etc., to judge the tire condition and the impact on the vehicle safety system. The sensor of the smart tire system is generally installed in the tire, and collects the parameters of the tire, and transmits the data to the control unit of the receiving system through wireless communication, and calculates and judges whether the condition of the tire is good. When necessary, an alarm is issued or relevant actions are performed, thereby improving vehicle safety. General smart tire systems communicate using low frequency and radio frequency systems. [0003] Smart tire system positioning is to find the position of each smart tire ...

Problems solved by technology

The smart tire system positioning must be correct and needs to be set in the smart tire system, otherwise it may cause error messages

[0004] Intelligent tire position recognition is generally identified according to the ID code of the tire pressure sensor module. After installing the tire, it is necessary to manually input the ID code of the corresponding tire pressure sensor module into the central monitor. The operation is cumbersome and error-prone. Subsequent maintenance and replacement Tires need to re-enter the ID code, which is very inconvenient. In order to solve this problem, the inventor has designed a tire position automatic positioning method and system, such as a Chinese patent on a tire position automatic positioning method and system (application number is 201310465982.7), Receive tire status information through sensor components, determine the vehicle driving direction of each tire, and realize automatic positioning. However, the tire position positioning can only be enabled during the driving process of the vehicle, and automatic positioning in a static state cannot be realized.
