Abstract

A system for setting the communication protocol of a TPMS sensor comprises an electronic device and a handheld device. The electronic device is connected to a first database and displays a link graphic upon input of vehicle information. The handheld device is connected to a second database and, upon scanning the link graphic, receives a communication protocol from the first database or the second database. The communication protocol is used to fire the TPMS sensor. This eliminates the need to enter the vehicle information on the handheld device, thus overcoming the difficulties in operating and inputting the handheld device caused by small screens or input errors, thus facilitating the selection of different communication protocols for different vehicle models.

Description

Field of the invention

[0001] The present invention relates to a system and operating steps for setting the communication protocol or the identification code of a TPMS sensor based on scanning a link graphic by a handheld device. State of the art

[0002] Before the vehicle leaves the factory, the car manufacturer (also known as the original equipment manufacturer) installs TPMS sensors. After a certain period of time, the battery power of an (old) TPMS sensor is exhausted or almost exhausted, so it must then be replaced. Therefore, in the aftermarket (also known as AM), the TPMS manufacturer produces (new) TPMS sensors to replace the old TPMS sensors. The TPMS manufacturer conducts market research and knows in advance which tire sensor part number will be used in a specific vehicle from a specific original equipment manufacturer. Therefore, the TPMS manufacturer can enter and store the part number in its database. The TPMS manufacturer also knows which (new) TPMS sensor model and which communication protocol are more suitable for a specific original equipment manufacturer vehicle.Therefore, the appropriate TPMS sensor model and protocol name can also be entered and saved in the manufacturer's database.

[0003] Since there are many vehicle brands on the market and each brand launches different vehicle types every year, many types of vehicle information can be generated by combining make, year, and model, so the database usually stores a variety of vehicle information. In addition, vehicle information usually corresponds to a communication protocol. When replacing a new TPMS sensor, a suitable communication protocol must be selected and burned into the new TPMS sensor so that the new TPMS sensor can communicate with the control unit or tire pressure receiver via this communication protocol. Therefore, different communication protocols corresponding to different vehicle information are also stored in the database. For example, when replacing a new TPMS sensor, a handheld device must be held and operated.The vehicle's make, year, and model are then selected on the handheld, or the vehicle's manufacturer's key number (HSN) and type key number (TSN) are entered (HSN and TSN are used only in Germany). A suitable communication protocol can then be selected from the many communication protocols stored on the handheld. The communication protocol is then burned and written to the new TPMS sensor.Then, the handheld device is operated again and the same make, year and model are selected or the HSN and TSN are entered, so that a method suitable for the current vehicle to put the control unit into the learning state can be selected from the many methods stored in the handheld device. The text-based method is displayed on the small screen of the handheld device, and then the operator operates various parts of the vehicle according to the method, which can put the control unit into the code learning state (the state in which it learns to receive the identification code of a TPMS sensor).This allows the control unit to receive and store the identification code of the new TPMS sensor. The new TPMS sensor sends a tire pressure signal (including the TPMS sensor identification code) to the control unit via an appropriate communication protocol so that the control unit can recognize the tire pressure signal. Therefore, the process must be performed twice: selecting the make, year, and model, or entering the HSN and TSN of a vehicle, which is time-consuming. The small screen of this handheld device also makes it difficult to display and operate. This can easily lead to the operator accidentally selecting the wrong communication protocol, making the entire installation and burning process time-consuming.If the vehicle owner repeatedly goes to the factory for repairs due to installation errors, this also reduces the vehicle owner's confidence in the professionalism of the operator.

[0004] In addition, information such as the make, year, and model entered on the handheld device is not saved. The next time the same vehicle comes to the factory for a TPMS sensor replacement, information such as the make, year, and model must be entered again. Or, after entering information such as the make, year, and model, maintenance personnel may not immediately exit the communication protocol and, for example, exit the page to view more installation information. Therefore, the information entered on a handheld device may be deleted when using other functions. Therefore, after entering information such as the make, year, and model on a handheld device, it is necessary to save the results. This is also one of the problems that the present invention aims to solve.DE102023126342 A1 discloses a system for setting the identification code of a TPMS sensor, comprising a TPMS sensor, a database, and a handheld device.

[0023] For a better understanding of the objects, features and advantageous effects of the present invention, the preferred embodiments will be described in detail below with reference to the accompanying drawings.

[0024] It is based on the Fig. 1, Fig. 2 and Fig. 3. A system for setting the communication protocol or the identification code of a TPMS sensor comprises an electronic device 10 and a handheld device 20, wherein the electronic device 10 is connected to a first database 11, and the first database 11 is the internal storage space of the electronic device 10. Or, the electronic device 10 is connected to a web server 12, wherein the first database 11 is a cloud database installed on the web server 12, and the electronic device 10 is a desktop computer, a notebook, a tablet computer, or a smartphone, i.e., the electronic device 10 should have electronic input and display functions. Accordingly, after vehicle information 101 is entered into the electronic device 10, a link graphic 102 is displayed. The input methods include, among others, keyboard input, input via touch interfaces, mouse input, voice input, and image input.The link graphic 102 may be a graphic such as a barcode or a QR (Quick Response) code, but is not limited to these. The link graphic 102 can be obtained by searching the first database 11. Furthermore, the link graphic 102 includes a communication protocol command 103 and a communication protocol path 104. The vehicle information 101 includes one of vehicle brand information, a manufacturer's key number (HSN), and a type key number (TSN), where HSN corresponds to the brand, TSN corresponds to the year and model, and the vehicle brand information includes information such as the make, year, and model (the three are referred to as MMY).The handheld 20 is connected to an operating module 21, wherein the operating module 21 is connected to a lens module 22 or an infrared module 22A. The lens module 22 or the infrared module 22A serves to capture the link graphic 102, the operating module 21 serves to select an appropriate communication protocol 201, and the lens module 22 or the infrared module 22A serves to scan or record a one-dimensional barcode, a two-dimensional QR code, or the numbers on a tire surface. The numbers on the tire surface can be, for example, a tire ID. Using image processing software, a photo can be recognized to obtain the tire ID. Furthermore, the handheld 20 is connected to a second database 23.After the link graphic 102 is scanned by the lens module 22 or the infrared module 22A, a search is performed for the specified communication protocol 201 in the second database 23 on the handheld device 20 according to the communication protocol command 103. If the specified communication protocol 201 is not found, the communication protocol path 104 is used to download it from the first database 11. In this way, the communication protocol 201 can be automatically obtained from the first database 11 or the second database 23. In this way, it is not necessary to input the vehicle information 101 on the handheld device 20, thereby overcoming the difficulties in operating and inputting the handheld device 20 caused by small screens or input errors, and thus facilitating the selection of different communication protocols 201 for different vehicle models.The handheld 20 can be a smartphone or an adjustment device provided by a TPMS sensor manufacturer.

[0025] The advantageous effects are described below. The electronic device 10 is connected to the first database 11, and the handheld device 20 is connected to the second database 23. The vehicle information 101 (such as the make, year, and model—the three are referred to as MMY) is input into the electronic device 10. The handheld device 20 automatically obtains the communication protocol 201 from the first database 11 or the second database 23. That is, the first database 11 or the second database 23 can be automatically updated via the network according to the continuous increase in models, so that the new communication protocol 201 can generate a new link graph 102 accordingly, preventing the appropriate or latest link graph 102 from being missed.

[0026] It is based on the Fig. 4 and Fig. 5. The communication protocol 201 of the handheld device 20 is used for communication and for burning the TPMS sensor 30. The method can be a low-frequency connection or a Bluetooth connection: 1. The handheld device 20 comprises a low-frequency transceiver 24 that can transmit low-frequency (LF) signals. The low frequency is 125 kHz. The handheld device 20 uses the low-frequency transceiver 24 to burn the communication protocol 201 into the TPMS sensor 30; 2. The handheld device 20 comprises a first Bluetooth module 25, and the TPMS sensor 30 comprises a memory module 31 and a second Bluetooth module 32, wherein the handheld device 20 communicates with the second Bluetooth module 32 via the first Bluetooth module 25 to store the communication protocol 201 in the memory module 31 of the TPMS sensor 30.In this case, the handheld 20 can be a handheld device, which is an adjustment tool manufactured or sold independently of a vehicle and by a TPMS sensor manufacturer. The handheld 20 can be carried by the user and used in any desired position.

[0027] It will be Fig. 6. The TPMS sensor 30 comprises a control module 33, a detection module 34, a transmission module 35, and a power module 36, the last three of which are each electrically connected to the control module 33. The power module 36 supplies power to the TPMS sensor 30, the detection module 34 is controlled by the control module 33 to detect tire information 301, and the transmission module 35 transmits the tire information 301 to the outside and receives external signals. The detection module 34 comprises an air pressure sensor 341, at least one acceleration sensor 342, a temperature sensor 343, and a magnetic field sensor 344. A connection is established between the handheld device 20 and the TPMS sensor 30 via the communication protocol 201.The handheld receives tire information 301, including tire pressure, acceleration, temperature, and magnetic field signals, from the transmission module 35. The tire information 301 is sent back to the electronic device 10 via the handheld 20. The first database 11 stores and analyzes the usage of the TPMS sensor 30, thereby predicting the need for tire adjustment and replacement. Furthermore, the tire information 301 can be stored for big data analysis, based on which the TPMS sensor 30 can be improved.

[0028] It will be Fig. 7. After the vehicle information 101 has been entered into the electronic device 10, the electronic device 10 additionally displays an illustrative code learning process graphic 105. The illustrative code learning process graphic 105 includes either an OBD (On-Board Diagnostic) code learning, an automatic code learning, a TOOL trigger code learning, or a pressure relief-based code learning. As in Fig. 8, OBD code learning means that the handheld 20 is wired into the OBD system of a vehicle to send the identification code 302 to the control unit 40. As shown in Fig. 9, automatic code learning means that after a certain time after starting a vehicle, the control unit 40 without the handheld 20 automatically receives the identification code 302 of a TPMS sensor 30 sent by the TPMS sensor 30. Since an acceleration sensor 342 is arranged in a TPMS sensor 30, the acceleration sensor 342 detects accelerations in different directions due to the rotation of the tire, so that a TPMS sensor 30 is triggered and sends an identification code 302 to the control unit 40. As shown in Fig. As shown in Figure 10, tool-triggered code learning means that a handheld device 20 wirelessly sends a signal to trigger a TPMS sensor 30, which then sends an identification code 302 to the control unit 40. Pressure-relief-based code learning means that a TPMS sensor 30 detects that the tire pressure has dropped due to pressure relief, is triggered, and sends the identification code 302 to the control unit 40. Specifically, in the present invention, graphics and search information of various code learning processes are pre-stored in the first database 11. Simply inputting the make, year, and model and / or HSN / TSN of a vehicle into the electronic device 10 can obtain a link graphic 102 and a suitable illustrative code learning process graphic 105.The code learning process (process of learning the identification code of a TPMS sensor) is a process in which a control unit 40 is placed in learning mode to learn the identification code of a TPMS sensor 30. When the control unit 40 is in learning mode, it can receive the identification code 302 from this TPMS sensor 30, from a handheld device 20, or from other devices. Accordingly, the operator can quickly place the control unit 40 in the state in which it can receive the identification code 302 of a TPMS sensor 30 according to the illustrative code learning process graphic 105. In order to find out how to enter the code learning mode for the control unit 40 of a specific vehicle type, it is no longer necessary to perform complicated operations on a handheld device 20 or a mobile phone. This is the process shown in . Fig. 11, the illustrative code learning process graphic 105 is an OBD code learning process and in the Fig. 12 is a TOOL trigger code learning process. Furthermore, a connection exists between the electronic device 10 and a printer 13. After the handheld device 20 scans the link graphic 102, the printer 13 automatically prints the illustrative code learning process graphic 105, allowing the operator to take and view the illustrative code learning process graphic 105 and establish a connection with the control device 40 according to the illustrative code learning process graphic 105.

[0029] It will be Fig. 13, which illustrates the OBD code learning process. A control unit 40 or a tire pressure receiver 30A has an identification code 302, and the identification code 302 is used for the control unit 40 or the tire pressure receiver 30A to determine which TPMS sensor is connected to it. The tire pressure receiver 30A serves as a receiving device when the control unit 40 cannot establish a direct connection to the TPMS sensor. An electronic device 10 is connected to a first database 11. Upon input of vehicle information 101, a link graphic 102 is displayed. A handheld device 20 includes a second database 23 and an OBD interface 26. After the OBD interface 26 has been connected to the control unit 40 or the tire pressure receiver 30A and the handheld device 20 has scanned the link graphic 102, a communication protocol 201 is obtained from the first database 11 or the second database 23.The control unit 40 or the tire pressure receiver 30A communicates with the OBD interface 26 via the communication protocol 201 to receive the identification code 302. When the handheld device 20 is connected to a TPMS sensor 30 (a new product to be replaced) via the communication protocol 201 for burning, the identification code 302 is synchronously transmitted to the TPMS sensor 30.

[0030] Here, the identification code 302 (identification code, ID) is the identification code 302 of a TPMS sensor 30. Each TPMS sensor 30 has a unique identification code 302. The control unit 40 identifies a TPMS sensor 30 by receiving a tire pressure signal containing an identification code 302. An identification code 302 can consist of any permutation and combination of numbers, codes, encodings, or symbols and is used to identify a TPMS sensor 30.

[0031] It will be Fig. 14, which shows another specific embodiment. A system for setting the communication protocol or the identification code of a TPMS sensor comprises the following: a first TPMS sensor 30B having an identification code 302; a second TPMS sensor 30C comprising a storage device 37; an electronic device 10 connected to a first database 11 and displaying a link graphic 102 upon input of vehicle information 101; a handheld device 20 connected to a second database 23, wherein, upon scanning the link graphic 102, a communication protocol 201 is obtained from the first database 11 or the second database 23, and the communication protocol 201 is used to establish a connection with the first TPMS sensor 30B and the second TPMS sensor 30C, wherein the handheld device 20 further comprises a wireless trigger module 27 or a human-machine interface 28.The handheld device 20 transmits the identification code 302 by one of the following two methods: (1) To obtain the identification code 302, the first TPMS sensor 30B is wirelessly triggered by the wireless trigger module 27, and the handheld device 20 is connected to the second TPMS sensor 30C and transmits the identification code 302; (2) The human-machine interface 28 is manually triggered or adjustable, wherein an identification code 302 input into the first TPMS sensor 30B is read by the handheld device 20 and then transmitted to the second TPMS sensor 30C. In summary, the present invention provides a method for retrieving a communication protocol, and completing the setting along with performing ID copying. The term ID copying means obtaining the same ID from the old first TPMS sensor 30B and copying it to the new second TPMS sensor 30C.

[0032] It will be Fig. 15, which shows yet another specific embodiment. A system for setting the communication protocol of a TPMS sensor comprises an electronic device 10, a handheld device 20, and a TPMS sensor 30. The TPMS sensor 30 comprises at least one acquisition module 34 and a first transmission module 38, and the acquisition module 34 acquires tire information 301. The electronic device 10 is connected to a first database 11 and a receiving module 14 and, after inputting vehicle information 101, performs a search in the first database 11 and then generates and displays a link graphic 102. The handheld device 20 is connected to a second database 23 and a second transmission module 29 and, after scanning the link graphic 102, receives a communication protocol 201 from the first database 11 or the second database 23.wherein a connection is established with the communication protocol 201 between the handheld device and the corresponding TPMS sensor 30, and the tire information 301 is transmitted by means of the first transmission module 38 and the second transmission module 29. The tire information 301 includes at least tire pressure data or also acceleration, temperature, or magnetic field signals, etc., wherein, for transmitting the tire information 301 to the electronic device 10, a connection is established between the second transmission module 29 and the reception module 14 in order to effectively collect the tire information 301 for analysis and storage. The electronic device 10 has a first input interface 15, and the handheld device 20 has a second input interface 281.The vehicle information is input via the first input interface 15 or the second input interface 281. The vehicle information is the license plate number or the VIN (Vehicle Identification Number). By creating service history information using the tire information 301 in the electronic device 10, vehicle maintenance, consumable replacement, and vehicle usage can be recognized. Furthermore, the first input interface 15 and the second input interface 281 are touchscreens, external keyboards, or external mice.

[0033] It will be Fig. 16, which shows yet another specific embodiment. A system for setting the communication protocol of a TPMS sensor comprises the following: the TPMS sensor 30, which includes a storage device 37, wherein a plurality of communication protocols 201 are stored in the storage device 37; an electronic device 10 connected to a first database 11, wherein, after input of vehicle information 101, a search operation is performed in the first database 11, whereby a link graphic 102 is displayed on the electronic device 10, and the link graphic 102 contains a communication protocol command 103; a handheld device 20, wherein, after scanning the link graphic 102 by the handheld device 20, it receives the communication protocol command 103, and the handheld device 20 subsequently sends the communication protocol command 103 to the TPMS sensor 30.whereby the TPMS sensor 30 selects a corresponding communication protocol 201 in the storage device 37 according to the communication protocol command 103, thereby establishing or performing a connection and adjustment of the TPMS sensor 30. This provides another method for adjusting a TPMS sensor 30. Here, the link graphic 102 is unique, meaning that the electronic device 10 generates and displays only a single link graphic 102. If the same vehicle information 101 is entered at any time, only the same link graphic 102 is displayed. Furthermore, multiple link graphics 102 are not displayed, so the operator does not have to identify which link graphic 102 is being used, and the incorrect link graphic 102 is not scanned or photographed, thus achieving the beneficial effect of intuitive burning.

[0034] It will be Fig. 17, which shows yet another specific embodiment. A system for setting the communication protocol of a TPMS sensor comprises the following: an electronic device 10 connected to a first database 11, wherein, after input of vehicle information 101, a search is performed in the first database 11 and a link graphic 102 is then generated and displayed; a handheld device 20 connected to a second database 23 and a human-machine interface 28, wherein the human-machine interface 28 can be manually triggered or set to create vehicle information 202. The vehicle information 202 includes the vehicle license plate number or the VIN.After scanning the link graphic 102, a communication protocol 201 is obtained from the first database 11 or the second database 23. A connection to the communication protocol 201 is established between the handheld device 20 and the TPMS sensor 30 for burning. After confirmation of a successful burning process, the link graphic 102 is linked to the vehicle information 202. Accordingly, the next time the TPMS sensor 30 is replaced and a burning process is performed for it, the link graphic 102 can be generated directly using simple input conditions. In this way, the communication protocol 201 can be directly specified and used.

[0035] It will be Fig. 17. Furthermore, the link graphic 102 is uploaded and, after the link graphic is linked to the vehicle information 202, stored in the first database 11 or the second database 23. When the TPMS sensor 30 is replaced again on the same vehicle, vehicle information 202—either the license plate number or the VIN—is selected for input into the electronic device 10, and the link graphic 102 is generated by the electronic device 10. Or, the vehicle information 202—either the license plate number or the VIN—is selected for input into the handheld device 20, and the communication protocol 201 is directly specified by the handheld device 20, eliminating the need to re-enter the MMY or HSN / TSN into the electronic device 10 or the handheld device 20, thus facilitating installation.Here, the vehicle information 202 further comprises an identification code 302, wherein the human-machine interface 28 can be manually triggered or set, whereby the handheld 20 reads the entered identification code 302 and then transmits it to the TPMS sensor 30 to be replaced.

[0036] It is based on the Fig. 18 and Fig. 19, which shows the operating steps for setting the communication protocol of a TPMS sensor. The operating steps are described below: Step 1: Inputting vehicle information 101 using a first device 10A, searching an internal or external database, and specifying a corresponding communication protocol command 103, wherein the internal database is the memory of the first device 10A and the external database is the connected external cloud database; Step 2: Creating a link graphic 102 using the communication protocol command 103 and displaying this link graphic 102 on the first device 10A, wherein the first device 10A searches the internal or external database according to the vehicle information 101 and obtains and displays an illustrative code learning process graphic 105, wherein the illustrative code learning process graphic 105 serves to support the operation of a control unit 40 and to evaluate the TPMS sensor 30; Step 3: Scanning the link graphic 102 by means of a second device 20A and executing the communication protocol command 103, wherein the link graphic 102 may be a two-dimensional barcode (e.g., a QR code) and the communication protocol command 103 may be a URL string or a string of program codes; Step 4: Searching an internal or external database by means of the second device 20A according to the communication protocol command 103 to obtain a communication protocol 201, wherein the link graph 102 comprises a communication protocol path 104, wherein, if the second device 20A searches the internal database for the specified communication protocol 201 according to the communication protocol command 103 and the specified communication protocol 201 is not found, the communication protocol path 104 is used to download from the external database, wherein the external database is a cloud database installed on a web server 12; and Step 5: Burning the TPMS sensor 30 using the communication protocol 201 by means of the second device 20A, wherein after burning, the TPMS sensor 30 sends a signal of successful burning to the second device 20A, thus completing the operations for setting the communication protocol 201 and burning the TPMS sensor 30.

[0037] The following describes the operating steps for setting the identification code of a TPMS sensor: Method 1: The second device 20A has an OBD interface 26, wherein, after the OBD interface 26 has been connected to a control unit 40 and the second device 20A has scanned the link graphic 102, a communication protocol 201 is obtained from an internal or external database, wherein to receive an identification code 302, the communication protocol 201 and the OBD interface 26 establish a connection to the control unit 40, wherein, when the second device 20A establishes a connection to the TPMS sensor 30 via the communication protocol 201 for firing, the second device synchronously transmits the identification code 302 to the TPMS sensor 30. Method 2: The second device 20A comprises a wireless trigger module 27, wherein to obtain an identification code 302, the second device 20A triggers an old TPMS sensor 30 by means of the wireless trigger module 27, wherein when the second device 20A establishes a connection to a new TPMS sensor 30 via the communication protocol 201 for firing, the second device synchronously transmits the identification code 302 to the new TPMS sensor 30. Method 3: The second device 20A has a human-machine interface 28, wherein the human-machine interface 28 is manually triggerable or adjustable, wherein the second device 20A reads an input identification code 302 and then transmits this identification code 302 to the TPMS sensor 30.

[0038] The present invention further includes a burn confirmation mechanism. The burn confirmation mechanism consists in that, after the second device 20A (handheld) burns the TPMS sensor 30, the TPMS sensor 30 sends back the communication protocol 201 and an identification code 302 to the second device 20A. At this time, the second device 20A compares the returned identification code 302 with the identification code 302 originally burned into the TPMS sensor 30 to determine if the two are the same. If the two are the same, it means that the burn was successful, and if the two are not the same, it means that the burn failed. This allows the operator to be immediately informed of the burn result and, if the burn failed, to repeat the burn or change the operating method.
