Description

[Technical field]

[0001] The present invention relates to an automatic tire positioning system for wireless tire pressure detectors and a method for implementing the same. [Background technology]

[0002] With the progress of the times, in modern society, drivers must always be aware of the condition of the tires of their vehicles, avoid sudden tire punctures and insufficient air pressure, and drive safely, so that currently many domestic vehicles are equipped with tire pressure detection systems. A typical tire pressure detection system is composed of tire pressure detectors respectively attached to the vehicle rims and a detector body inside the vehicle, and each tire pressure detector reads the air pressure in the corresponding tire within a certain period of time, or other pre-installed parameters such as tire temperature, tire humidity, etc., and transmits the reading results to the detector body.

[0003] In the tire pressure detection system, the market vendors usually adopt a recording method to make the detector body distinguish the tire pressure detectors on different wheels, which uses equipment to make the detector body record the corresponding position and serial number of each tire pressure detector, providing identification and understanding. This kind of method has good stability.

[0004] Although this method is certainly stable, if the tire pressure detector needs to be replaced or if there is an error in the recorded information, it is generally necessary to return it to the factory to have it recorded again, which is very troublesome and places a burden on the user. Therefore, the manufacturer has invented a wireless tire pressure detector with a wireless tire positioning system, which uses a wireless tire positioning method to make the detector body detect the tire position of each wireless tire pressure detector, and allows the user to replace each tire pressure detector, making it even more convenient.

[0005] However, the wireless tire pressure detector systems with wireless positioning function on the market have the problem that the detector body installed in the vehicle accurately locates the position of the wireless tire pressure detector, and the detector body usually needs to be significantly modified to achieve the positioning effect. Therefore, the detector body system needs to be modified and a new calculation method written in, and only then can the wireless tire pressure detector be effectively located, which causes inconvenience to users.

[0006] If the above situation could be improved, the power consumption problem of wireless tire pressure detectors would be effectively reduced while still having tire positioning function, driving range would be improved, and purchasing desire for wireless tire pressure detectors with tire positioning function would be effectively increased. Summary of the Invention [Problem to be solved by the invention]

[0007] It includes a detector body, a wheel rotation detection device and a wireless tire pressure detector. Through the wireless tire pressure detector, the gear rotation information transmitted by the wheel rotation detection device transmitted by the detector body is received and compared with the tire rotation information acquired by the wireless tire pressure detector itself, and each wireless tire pressure detector confirms and derives the corresponding wheel rotation detection device, and at the same time, it also determines and outputs the wheel position where each wireless tire pressure detector is located. Compared with the prior art, the present invention is the main objective of providing a tire automatic positioning system and its implementation method for a wireless tire pressure detector, which can determine the wheel position where each wireless tire pressure detector is located without separately modifying the detector body, and greatly reduce the trouble for users to replace the wireless tire pressure detector. [Means for solving the problem]

[0008] In order to achieve the above objectives and advantages, the present invention provides a tire automatic positioning system of a wireless tire pressure detector, which includes a detector body, a wheel rotation detection device and a wireless tire pressure detector, wherein the detector body includes a transceiver module and a memory module electrically connected to each other, and the memory module records information received by the transceiver module.

[0009] Then, the wheel rotation detection device is installed on each tire and electrically connected to the detector body, the wheel rotation detection device includes a gear ring and a sensor electrically connected to each other, the sensor continuously transmits the rotation data of the gear ring to the transceiver module, and the tire position of each wheel rotation detection device is recorded in the detector body.

[0010] Finally, the wireless tire pressure detector is installed in each tire and is bidirectionally wirelessly connected to the detector body, and the wireless tire pressure detector is installed at a position different from the wheel rotation detection device, and the wireless tire pressure detector includes a sensing module, a main control module and a calculation processing module which are electrically connected to each other, the sensing module senses and transmits tire rotation information to the main control module, and the calculation processing module calculates and processes the information obtained by the main control module.

[0011] When the wireless tire pressure detector operates in the positioning mode, the wireless tire pressure detector first collects tire rotation information at a set time or a set tire rotation angle, then requests and obtains all the gear rotation information and wheel rotation detection device position information from the memory module of the detector body through the main control module, and finally performs a comparison calculation with the information in the main control module through the calculation processing module, so that the wireless tire pressure detector finds its corresponding wheel rotation detection device and further determines its own tire position.

[0012] In order to further achieve the objectives and effects, the present invention provides another implementation method, which includes a connection and transmission step, a synchronous positioning step, a first information collecting step, a second information collecting step, a calculation step and a reporting step, in which the connection and transmission step refers to the detector body wirelessly or electrically connecting with the wheel rotation detecting device and the wireless tire pressure detector respectively, and the wheel rotation detecting device continuously transmitting the rotation information of the corresponding gear ring to the transceiver module of the detector body through the sensor.

[0013] The synchronous positioning step refers to, after the connection and transmission step is completed, the detector body notifies the wireless tire pressure detector through a wireless two-way request to activate the positioning mode, and activates the sensing module to prepare for collecting tire rotation information.

[0014] Next, the first information collecting step refers to, after completing the synchronous positioning step, the sensing module transmits first tire rotation information to the main control module at the set first time or first tire rotation angle, and when the main control module receives the first tire rotation information, it sends a first message request to the memory module of the detector body, and the memory module reads the rotation information of the first gear ring and the position information record of the wheel rotation detection device, and feeds it back to the main control module of the wireless tire pressure detector.

[0015] And the second information collecting step refers to, after completing the first information collecting step, the sensing module transmits second tire rotation information to the main control module at the set second time or second tire rotation angle, and when the main control module receives the second tire rotation information, it sends a second message request to the memory module of the detector body, and the memory module reads the record of the rotation information of the second gear ring, and feeds it back to the main control module of the wireless tire pressure detector.

[0016] Furthermore, the calculation step refers to, after completing the second information collecting step, when the main control module receives the rotation information of the first gear ring, the wheel rotation detection device position information and the rotation information of the second gear ring from the detector body, through a calculation processing module, comparing and calculating the first tire rotation information and the second tire rotation information, and the wireless tire pressure detector itself calculates the corresponding wheel rotation detection device, and determines the position of the tire installed by itself.

[0017] Finally, the reporting step refers to, after the calculation step is completed, the wireless tire pressure detector feeds back the positioning result to the detector body, and causes the detector body to display or perform an operation or the like.

[0018] In actual use, when the wireless tire pressure detector operates in the positioning mode, the wireless tire pressure detector records the tire rotation information at the time when the tire rotates to two specific times or angles (for example, the angle of the tire rotation at the first and second times, or the time of the tire rotation at the first and second angles), and then, after the wireless tire pressure detector receives the above-mentioned information, it requests the detector body to read the gear rotation information of the wheel rotation detection device (for example, the angle or time), and then compares the above-mentioned information with each other to calculate which wheel rotation detection device the wireless tire pressure detector corresponds to. Furthermore, since the tire position of each wheel rotation detection device is registered by the detector body in advance (the conventional known technology), each wireless tire pressure detector can automatically calculate and determine the tire position where it should be installed.
