Description

Technical Field

[0001] The present invention relates to a tire positioning system for a wireless tire pressure detector and a method for implementing the same.

Background Art

[0002] With the progress of the times, in modern society, drivers always have to grasp the condition of the vehicle tires, avoid sudden tire punctures and insufficient air pressure, and drive safely. Therefore, at present, many domestic vehicles are equipped with a tire pressure detection system. A general tire pressure detection system is composed of tire pressure detectors respectively mounted on vehicle rims and a detector body inside the vehicle. Each tire pressure detector reads the air pressure inside the corresponding tire within a certain period of time, or other pre-set parameters such as tire temperature and tire humidity. Then the read result is transmitted to the detector body.

[0003] For the method by which market vendors make the detector body distinguish tire pressure detectors on different wheels in a tire pressure detection system, the usual recording method is adopted. It uses equipment to record the corresponding positions and serial numbers of each tire pressure detector on the detector body to provide identification and understanding. This kind of method has good stability.

[0004] However, although this kind of method is indeed stable, when the tire pressure detector is replaced or there is an error in the recorded information, generally it is necessary to send it back to the factory for re-recording, which is very troublesome and burdens the user. Therefore, vendors invented a wireless tire pressure detector with a wireless tire positioning system, and in the wireless tire positioning method, the detector body senses the tire position where each wireless tire pressure detector is located, enabling the user to replace each tire pressure detector, making it more convenient.

[0005] However, wireless tire pressure detectors with a wireless tire positioning function on the market have a problem of high power consumption, resulting in poor endurance. Since the detector body inside the vehicle needs to accurately position the wireless tire pressure detector, general wireless tire pressure detectors on the market adopt a method of continuously transmitting tire positioning information to the detector body for a long time. This kind of method is indeed accurate, but if the positioning information is continuously sent for a long time, the wireless tire pressure detector will consume high power, and the service life of the wireless tire pressure detector will also be shortened.

[0006] If the above situation can be improved, while having the tire positioning function, the power consumption problem of the wireless tire pressure detector can be effectively reduced, the endurance can also be improved, and the purchase intention of the wireless tire pressure detector with the tire positioning function can be effectively enhanced.

Summary of the Invention

Problems to be Solved by the Invention

[0007] It includes a plurality of wheel rotation detection devices, a detector body, and a plurality of wireless tire pressure detectors. By receiving, the detector body compares the corresponding gear ring rotation information transmitted by the plurality of wheel rotation detection devices and the corresponding tire rotation information transmitted by the plurality of wireless tire pressure detectors, and further confirms the tire positions where each wireless tire pressure detector is installed. At the same time, since the detector body and the wireless tire pressure detector have a two-way transmission function, the detector body responds quickly, and after the calculation is completed and at that time, it commands the wireless tire pressure detector to stop the sensor transmission operation, aiming to provide a tire positioning system for the wireless tire pressure detector and its implementation method to reduce the power consumption of the wireless tire pressure detector.

Means for Solving the Problems

[0008] To achieve the above object and effect, the present invention provides a tire positioning system for a wireless tire pressure detector. It includes a plurality of wheel rotation detection devices, a detector body, and a plurality of wireless tire pressure detectors. Among them, the detector body includes a wired transceiver module, a calculation processing module, and a wireless bidirectional transceiver module that are electrically connected to each other. The calculation processing module calculates and processes the information received by the wired transceiver module and the wireless bidirectional transceiver module.

[0009] Furthermore, the plurality of wheel rotation detection devices are installed on each tire and are wirelessly or electrically connected to the detector body. The plurality of wheel rotation detection devices include a gear ring and a sensor that are electrically connected to each other. Among them, the sensor continuously transmits the rotation information of the gear ring to the wired transceiver module. Each wheel rotation detection device installed at the tire position is registered in the detector body (prior art).

[0010] Finally, the plurality of wireless tire pressure detectors are installed on each tire and are wirelessly connected bidirectionally to the wireless bidirectional transceiver module of the detector body. Moreover, each wireless tire pressure detector and each wheel rotation detection device are installed at different positions of the same tire. The plurality of wireless tire pressure detectors include a sensing module, an information module, and a control module that are electrically connected to each other. The detector body issues a command to the control module via the wireless bidirectional transceiver module, and the control module controls the operation or stop of the sensing module.

[0011] When the sensing module operates, it transmits tire rotation information to the wireless bidirectional transceiver module of the detector body via the information module at the time set by the sensing module or at the set tire rotation angle.

[0012] To achieve the above object and effect, the present invention provides another implementation method thereof. It includes a wireless connection determination step, a tire positioning start step, a first information collection step, a second information collection step, a calculation step, and a tire positioning end step. Among them, the wireless connection determination step means that the detector body is respectively connected to a plurality of wheel rotation detection devices and a plurality of wireless tire pressure detectors, and the detector body establishes a wireless bidirectional connection with the plurality of wireless tire pressure detectors, and the plurality of wheel rotation detection devices continuously transmit the rotation information of the corresponding gear ring to the wired transceiver module of the detector body through the sensor.

[0013] The tire positioning start step means that after the completion of the wireless connection determination step, the wireless bidirectional transceiver module of the detector body transmits a command to activate the sensing module to the control module of the plurality of wireless tire pressure detectors.

[0014] Next, the first information collection step means that after the completion of the tire positioning start step, the control module activates the sensing module, and when the sensing module reaches the set first time or the first tire rotation angle, the first tire rotation information is transmitted to the wireless bidirectional transceiver module of the detector body through the information module. When the detector body receives the first tire rotation information, it reads and records the rotation information of the plurality of gear rings and sets the first tire rotation information.

[0015] Furthermore, the second information collection step means that after the completion of the first information collection step, when the sensing module reaches the set second time or the second tire rotation angle, the second tire rotation information is transmitted to the wireless bidirectional transceiver module of the detector body. When the detector body receives the second tire rotation information, it reads and records the rotation information of the plurality of gear rings and sets the second tire rotation information.

[0016] Furthermore, after the second information collection step is completed, when the detector main body receives the first tire rotation information and the second tire rotation information of the plurality of wireless tire pressure detectors, the calculation step is to perform a comparison calculation on the first tire rotation information and the second tire rotation information through the calculation processing module, calculate the position of each wheel rotation detection device corresponding to each wireless tire pressure detector by the detector main body, and locate the tire position where each wireless tire pressure detector is installed.

[0017] Finally, after the calculation step is completed, the tire positioning end step is that the detector main body locates and calculates the tire position where each wireless tire pressure detector is located, and the detector main body transmits a command to stop the sensing module to the control module of the wireless tire pressure detector through the wireless bidirectional transceiver module. When the control module receives the command, it means to stop the operation of the sensing module.

[0018] In actual use, when the detector main body has not yet located the tire position where each wireless tire pressure detector is located, the detector main body transmits information to activate the sensing module to each wireless tire pressure detector. Each wireless tire pressure detector transmits tire rotation information at two specific times or angles respectively (for example, the tire rotation angles at the first time and the second time, or the times of tire rotation at the first angle and the second angle). At the same time, when the detector main body receives the above information, it reads the rotation information (such as angle or time) of the gear ring of the wheel rotation detection device, compares the above information with each other to calculate which wheel rotation detection device each wireless tire pressure detector corresponds to, and since the tire position where each wheel rotation detection device is located has been pre-registered by the detector main body (prior art), the detector main body can calculate and position the tire position where each wireless tire pressure detector is installed.

[0022] As shown in FIGS. 1 to 4, the present invention is a tire positioning system for a wireless tire pressure detector 3, which includes a plurality of wheel rotation detection devices 2, a detector body 1, and a plurality of wireless tire pressure detectors 3.

[0027] Furthermore, the above-mentioned external control device 4 is a control panel of the detector main body 1, a wireless control tool, a software application, a wireless OTA (Over The Air) device, and a wireless remote control system.

[0028] The above are the technical features of the main embodiments of the present invention. It corresponds to the content of the first item of the claims of the present invention, and the purpose and embodiments of the present invention can be known. In addition, the features described in its dependent claims are those that detail or add to the content of the first item of the claims, and do not limit the scope of the first item of the claims. The first item of the claims of the present invention does not necessarily include the technical features described in its dependent claims.

[0029] As shown in FIGS. 1 to 5, the present invention provides a method for implementing a tire positioning system of the above-mentioned wireless tire pressure detector 3, which includes a wireless connection determination step S11, a tire positioning start step S12, a first information collection step S13, a second information collection step S14, a calculation step S15, and a tire positioning end step S16. Among them, the wireless connection determination step S11 means that the detector body 1 is respectively connected to a plurality of wheel rotation detection devices 2 and a plurality of wireless tire pressure detectors 3, and the detector body 1 establishes a wireless bidirectional connection with the plurality of wireless tire pressure detectors 3, and the plurality of wheel rotation detection devices 2 continuously transmit the rotation information of the corresponding gear ring 21 to the wired transceiver module 11 of the detector body 1 via the sensor 22.

[0030] The tire positioning start step S12 means that after the completion of the wireless connection determination step S11, the wireless bidirectional transceiver module of the detector body 1 transmits a command to activate the sensing module 31 to the control module 33 of the plurality of wireless tire pressure detectors 3.

[0031] Furthermore, the first information collection step S13 means that after the completion of the tire positioning start step S12, the control module 33 activates the sensing module 31, and when the sensing module 31 reaches the set first time or the first tire rotation angle, the first tire rotation information is transmitted to the wireless bidirectional transceiver module 13 of the detector body 1 via the information module 32. When the detector body 1 receives the first tire rotation information, it reads and records the rotation information of the plurality of gear rings 21 and sets the first tire rotation information.

[0032] Next, in the second information collection step S14, after the first information collection step S13 is completed, when the sensing module 31 reaches the set second time or the second tire rotation angle, the second tire rotation information is transmitted to the wireless bidirectional transceiver module 13 of the detector body 1. When the detector body 1 receives the second tire rotation information, it reads and records the rotation information of the plurality of gear rings 21, and sets the second tire rotation information.

[0033] Furthermore, next, in the calculation step S15, after the second information collection step S14 is completed, when the detector body 1 receives the first tire rotation information and the second tire rotation information of the plurality of wireless tire pressure detectors 3, a comparison calculation is performed on the first tire rotation information and the second tire rotation information via the calculation processing module 12. The detector body 1 calculates the position of each wheel rotation detection device 2 corresponding to each wireless tire pressure detector 3, and locates the tire position where each wireless tire pressure detector 3 is installed.

[0034] Finally, in the tire positioning end step S16, after the calculation step S15 is completed, the detector body 1 locates and calculates the tire position where each wireless tire pressure detector 3 is located. The detector body 1 transmits a command to stop the sensing module 31 to the control module 33 of the wireless tire pressure detector 3 via the wireless bidirectional transceiver module 13. When the control module 33 receives the command, it stops the operation of the sensing module 31.

The external control device 4 is connected to the detector body 1, and the external control device 4 controls the detector body 1 to issue an operation command to start or stop the plurality of wireless tire pressure detectors 3.

[0036] Furthermore, the above-described external control device 4 is a control panel of the detector body 1, a wireless control tool, a software application, a wireless OTA (Over The Air) device, and a wireless remote control system.

[0037] In actual use, as shown in FIGS. 1 to 5, when the detector main body 1 has not yet located the tire positions where each wireless tire pressure detector 3 is located, the detector main body 1 transmits information for operating the sensing module 31 to each wireless tire pressure detector 3. Each wireless tire pressure detector 3 transmits tire rotation information at two specific times or angles respectively (for example, the tire rotation angles at the first time and the second time, or the times of tire rotation at the first angle and the second angle). At the same time, when the detector main body 1 receives the above information, it reads the rotation information (such as angle or time) of the gear ring 21 of the wheel rotation detection device 2, compares the above information with each other to calculate which wheel rotation detection device 2 each wireless tire pressure detector 3 corresponds to, and since the tire positions where each wheel rotation detection device 2 is located are pre-registered by the detector main body 1 (conventional well-known technology), the detector main body 1 can calculate the tire positions where each wireless tire pressure detector 3 is installed and perform tire positioning.
