Description

Tire pressure sensor activation method, device and system Technical Field

[0001] The present application relates to the field of vehicles, and in particular to a tire pressure sensor activation method, device, and system. Background Art

[0002] TPMS (Tire Pressure Monitor System) stands for Tire Pressure Monitoring System. It automatically monitors tire pressure in real time while the vehicle is driving and issues alerts for leaks and low tire pressure to ensure driving safety. TPMS primarily consists of a tire pressure sensor (also known as a tire pressure sensor or TPMS sensor), an MCU (Microcontroller Unit), a radio frequency module, and an antenna.

[0003] At this stage, tire pressure sensors are usually wireless sensors. That is, after the tire pressure sensor collects relevant signals of parameters such as tire pressure, it will encode and modulate them into radio frequency signals and transmit them through the antenna so that the receiving device of the vehicle system can receive the radio frequency signal and decode it to obtain the parameter values ​​collected by the tire pressure sensor.

[0004] To ensure that the radio frequency signals emitted by tire pressure sensors installed on vehicle tires can be accurately received and identified by the vehicle, they must be activated when they are installed (e.g., factory-installed or repaired) so that the sensor and vehicle can recognize each other and communicate normally.

[0005] In related technologies, activation usually requires a dedicated activation tool. For example, the dedicated activation tool is connected to the vehicle via a special cable, or a VCI (Vehicle Communication Interface) device is connected to the vehicle via the OBD interface, and the dedicated activation tool and VCI device are connected via Bluetooth. The device is then operated through the VCI device's operating interface to achieve learning and matching.

[0006] However, the above-mentioned matching methods of related technologies often require special tools (special learning tools and VCI devices, etc.) and special connecting cables and other equipment. These devices are not only large in size and inconvenient to carry, but also expensive, relatively complex to operate and have a high threshold for use. As a result, the hardware cost and usage cost of the above-mentioned matching methods are generally high, and improvement is urgently needed.

[0038] The technical solutions provided by the embodiments of this application bring at least the following beneficial effects:

After the tire pressure sensor installed in the target tire collects the tire status data of the tire, it can send tire status data containing the target sensor identification and the tire status data to the target vehicle, so that the target vehicle can identify the tire status data from the tire pressure sensor (rather than the tire pressure sensors installed on other tires) based on the target sensor identification and perform subsequent processing such as displaying or judging the data. It can be seen that the activation system described in this solution can implement a complete activation process for the tire pressure sensor, including programming and learning, to ensure that the tire pressure sensor can work normally with the target vehicle after installation.

[0040] In addition, the aforementioned activation system consists of a tire pressure sensor, a target vehicle, an activation terminal, and an electronic device. Compared to the related art solutions, only conventional electronic devices are introduced. Specifically, compared to the special tools used in the related art, the activation terminal in the activation system can connect to the target vehicle through its own OBD interface and achieve wireless connection with the electronic device and tire pressure sensor through a built-in antenna module. Therefore, expensive equipment (such as dedicated learning tools, VCI equipment, or special connection cables) is not required, significantly reducing the hardware cost of the activation system. In addition, because the newly introduced electronic device can be a conventional electronic device such as a mobile phone or tablet computer, and such devices already have display functions and rich human-computer interfaces, based on the electronic device and wireless connection, the user only needs to perform simple operations in the operation interface of the electronic device to control the activation terminal. This not only reduces the user's operation and usage threshold, but also effectively simplifies the hardware structure and software logic of the activation terminal, helping to achieve miniaturization, portability, and minimalist operation of the activation terminal. As can be seen, the activation system described in this application achieves lightweight and miniaturization of the activation terminal by controlling the activation terminal through the electronic device, thereby reducing the hardware cost and usage cost of the tire pressure sensor activation process, and significantly reducing costs and increasing efficiency.

[0048] In order to enable ordinary people in the art to better understand the technical solutions of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings.

[0049] It should be noted that the terms "first," "second," and the like in the specification and claims of this application and the accompanying drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or precedence. It should be understood that the terms used in this manner are interchangeable where appropriate so that the embodiments of the application described herein can be implemented in an order other than those illustrated or described herein. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present application. Instead, they are merely examples of apparatus and methods consistent with certain aspects of the present application, as detailed in the appended claims.

[0050] To solve the aforementioned technical problems in related technologies, this application proposes an activation terminal and its associated activation system, as well as a tire pressure sensor activation solution implemented based on the activation system. Detailed descriptions are provided below with reference to the accompanying drawings.

[0051] The present application proposes an activation terminal, which includes a control module and a first antenna module, a second antenna module, an OBD interface and a power module connected thereto, wherein:

[0052] The first antenna module is used to establish a first wireless connection with an electronic device running an activation client, and the activation terminal is used to receive instructions or data sent by the activation client through the first wireless connection;

[0053] The second antenna module is used to establish a second wireless connection with the tire pressure sensor, and the activation terminal is used to write the target communication parameters of the target vehicle into the tire pressure sensor through the second wireless connection under the instruction of the activation client;

[0054] The OBD interface is used to establish a connection with the target vehicle, and the activation terminal is used to send the target sensor identifier of the tire pressure sensor to the target vehicle through the connection under the instruction of the activation client; the tire pressure sensor after installation is used to submit the status-related data of the target tire to the target vehicle according to the written target communication parameters, and the status-related data includes the target sensor identifier and the tire status data collected by the tire pressure sensor.

[0055] Among them, corresponding to the OBD interface on the activation terminal (hereinafter referred to as the first OBD interface), the target vehicle can also be equipped with a corresponding OBD interface (hereinafter referred to as the second OBD interface), so that the connection between the activation terminal and the target vehicle can be achieved based on the above two OBD interfaces. For example, the two interfaces can be connected by plugging in, such as when the first OBD interface is a male connector and the second OBD interface is a female connector, the male connector can be directly inserted into the female connector to achieve connection. For another example, if the location of the second OBD interface (such as under the steering wheel or instrument panel, etc.) is small and inconvenient to operate, the first OBD interface and the second OBD interface can be connected using a connecting line that conforms to the OBD interface protocol. It can be understood that no matter what method is used to achieve the connection, the first OBD interface and the second OBD interface are connections established based on physical entities such as cables and / or pins. Therefore, the connection established between the activation terminal and the target vehicle through the OBD interface should be understood as a wired connection.

[0056] As can be seen, the activation terminal establishes a first wireless connection with the aforementioned electronic device via the first antenna module, establishes a second wireless connection with the tire pressure sensor via the second antenna module, and establishes a wired connection with the target vehicle via the OBD interface (i.e., the aforementioned first OBD interface). The activation terminal cooperates with the tire pressure sensor, the target vehicle, and the electronic device running the activation client to implement the tire pressure sensor activation method described in any of the following embodiments.

[0057] As shown in FIG1 , the activation terminal 10 includes a first antenna module 11, a second antenna module 12, a control module 13, an OBD interface 14, and a power module 15. Among them, each module except the control module 13 is connected to the control module 13 respectively.

[0058] In one embodiment, the control module 13 may include a computing submodule (such as a CPU, etc.), a storage submodule (such as a memory, a storage chip, etc.), and necessary peripheral circuits. Other modules connected to the control module 13 may operate normally under the control of the control module 13.

[0059] In one embodiment, the first antenna module 11 may include an antenna T1 and a first signal processing circuit. It should be noted that although the antenna T1 and the first antenna module 11 are depicted as two separate parts, the antenna T1 should still be understood as being part of the first antenna module 11, i.e., the antenna T1 and the first signal processing circuit (not shown in the figure) together constitute the first antenna module 11. Antennas T2 and T3 described below are similar and will not be described in detail. The first antenna module 11 can be used to transmit and receive wireless signals (i.e., receive and / or transmit, hereinafter the same) to establish a wireless connection (i.e., the aforementioned first wireless connection) with electronic devices in the activation system and to interact with the activation client running therein. For example, the first wireless connection established between the activation terminal 10 and the mobile phone 31 via the first antenna module 11 can be a Bluetooth connection or a Wi-Fi connection, for example (e.g., a user can operate the activation terminal 10 and the mobile phone 31 to pair and connect Bluetooth signals, or can operate the mobile phone 31 to open a Wi-Fi hotspot and operate the activation terminal 10 to connect to the hotspot to establish a Wi-Fi connection with the mobile phone 31). In addition, the activation terminal 10 can also establish an infrared connection with the electronic device based on the corresponding hardware, and this application does not limit the connection method between the two. Taking Bluetooth connection as an example, the antenna T1 can receive the Bluetooth signal sent by the electronic device (in this case, the antenna T1 is used as a receiving antenna), and then the first signal processing circuit demodulates (or decodes) the Bluetooth signal and sends the processing result to the control module 13; the antenna T1 can also send the Bluetooth signal modulated (or encoded) by the electronic device to the surrounding space (in this case, the antenna T1 is used as a transmitting antenna).

[0060] In one embodiment, the second antenna module 12 may include a low-frequency module 121 and a high-frequency module 122. The activation terminal 10 may establish a wireless connection (i.e., the aforementioned second wireless connection) with the tire pressure sensor 32 via the second antenna module 12. Exemplarily, the wireless connection may be an NFC (Near Field Communication) connection or a wireless radio frequency connection (e.g., RFID, Radio-Frequency Identification), although this application is not limited thereto. When the NFC or wireless radio frequency connection is established between the activation terminal 10 and the tire pressure sensor 32, the two devices can achieve a device connection (or pairing) in milliseconds via a wireless wake-up signal. The awakened device (e.g., the tire pressure sensor 32) is essentially a passive device. During this connection process, the user does not need to manually perform "pairing" and "connection confirmation" operations similar to Bluetooth or WiFi technologies, facilitating rapid connection and information exchange between the devices. It should be noted that while the NFC or wireless radio frequency connection establishment process is extremely fast and is typically completed simultaneously with the data transmission process, the connection should still be considered a wireless connection, i.e., a wireless connection is established between the activation terminal 10 and the tire pressure sensor 32.

[0061] The low-frequency module 121 and the high-frequency module 122 can be used to transmit and receive different types of wireless signals, such as the low-frequency module 121 for transmitting and receiving NFC signals and the high-frequency module 122 for transmitting and receiving RFID signals. Alternatively, the low-frequency module 121 and the high-frequency module 122 can cooperate with each other to transmit or receive the same type of wireless signal, such as the low-frequency module 121 for transmitting 125 kHz low-frequency radio frequency signals and the high-frequency module 122 for receiving 315 MHz or 433 MHz high-frequency radio frequency signals, which will not be further described.

[0062] Taking the case where the wireless connection is an NFC connection as an example, antenna T2 and antenna T3 can serve as the receiving antenna and transmitting antenna of the NFC signal respectively. Of course, the tire pressure sensor that needs to establish an NFC connection with the activation terminal 10 should also include corresponding NFC components and antenna components. Given that the activation terminal 10 needs to read data (such as sensor identification, etc.) and write data (such as target communication parameters of the target vehicle, etc.) from the tire pressure sensor, the activation terminal 10 and the tire pressure sensor can use a point-to-point mode (P2P mode) to establish the NFC connection so that both parties can achieve efficient two-way data exchange. At this time, the NFC connection is established much faster than the infrared connection and Bluetooth connection, which helps to improve the interaction efficiency between the data activation terminal 10 and the tire pressure sensor.

[0063] Of course, when the electronic device establishes a third wireless connection with the vehicle, when the activation terminal establishes the aforementioned wired connection with the target vehicle through the OBD interface, and when the tire pressure sensor sends status-related data to the target vehicle, the vehicle should be in a startup state (or power-on state), that is, the target vehicle's vehicle system (at least its communication system) should be turned on and running.

[0064] Figure 2 is a schematic diagram of the appearance of an activation terminal according to an embodiment of the present application. As shown in Figure 2, an NFC sensing area 22 is provided at the center of the front of the activation terminal 10. An NFC signal antenna (such as the aforementioned antenna T2 and / or antenna T3, not shown in the figure) is connected below the sensing area. During use, the tire pressure sensor (such as the sensing area of ​​the sensor) can be placed in the NFC sensing area 22, and the activation terminal 10 can be triggered to establish an NFC connection with the tire pressure sensor 32 through corresponding operations.

[0065] Similar to the first antenna module 11, the low-frequency module 121 may include an antenna T2 and a low-frequency signal processing circuit, and the high-frequency module 122 may include an antenna T3 and a high-frequency signal processing circuit. Taking the scenario where the low-frequency module 121 transmits a low-frequency RF signal and the high-frequency module 122 receives a high-frequency RF signal as an example, the low-frequency signal processing circuit is used to modulate the low-frequency RF signal and transmit it to the surrounding space via antenna T2 so that the antenna in the tire pressure sensor can receive it. Correspondingly, after antenna T3 receives the high-frequency RF signal transmitted by the tire pressure sensor, the high-frequency signal processing circuit can perform noise reduction, demodulation, and other processing on the signal and transmit the processing results to the control module 13.

[0066] In addition, depending on the type of wireless connection established or the software function to be implemented by activating the terminal 10, any of the first antenna module 11, the low-frequency module 121, and the high-frequency module 122 can be set to operate in simplex mode or duplex mode. Specifically, if any of the modules operates in simplex mode, at any given moment, the antenna of the module only receives wireless signals or only transmits wireless signals; if any of the modules operates in duplex mode, the antenna of the module can both receive and transmit wireless signals at the same time.

[0067] In one embodiment, the OBD interface 14 can support OBD-Ⅱ (or OBD2, i.e., the second generation of vehicle fault diagnostic system) or OBD-Ⅲ (or OBD3, i.e., the third generation of vehicle fault diagnostic system) protocol. The activation terminal 10 can establish a wired connection with the target vehicle's own OBD interface (i.e., the aforementioned second OBD interface) through the OBD interface 14, so as to exchange data with the target vehicle through the connection. As shown in Figure 3, the front end of the activation terminal 10 is provided with an OBD interface 21. The specific meaning of each pin in the interface (not shown in the figure) can be found in the records in the relevant technology. In view of the fact that the OBD interface usually has an anti-foolproof design, illustratively, when the target vehicle's own OBD interface is a female socket, the OBD interface 21 can be a male connector.

[0068] In one embodiment, the activation terminal may further include a data interface module, which is used to connect a data management device so that the activation terminal and the data management device can interact with each other. As shown in Figure 2, a data interface 24 is provided at the lower tail of the activation terminal 10. Exemplarily, the data interface may be an interface such as USB, Type-C, etc. Among them, the data management device can store, edit and / or analyze the data, and the data before processing can be obtained from the activation terminal, or the processed data can also be sent to the activation terminal, which will not be repeated. Exemplarily, the data management device can be a mobile phone, computer, tablet or other device, which can be an electronic device that needs to establish a wireless connection with the activation terminal (such as the electronic device where the aforementioned activation client is located), or it can also be other electronic devices. Alternatively, the data management device can also be a storage device such as a U disk, SD card, etc., so that the storage diagnosis can send the current data to the device for storage or read the stored data from the device, etc., which will not be repeated.

[0069] Similar to the wired connection between the activation terminal and the target vehicle via the OBD interface, the connection between the activation terminal and the data management device via the data interface module can also be a wired connection, such as a plug-in connection or a connection via a data transmission line. Among them, the physical transmission line used to connect the activation terminal 10 and the data management device, its physical interface structure and the communication protocol it supports should match the data interface 24. After establishing a wired connection with the activation terminal 10 via the physical transmission line, the data management device can write data to the activation terminal 10 (such as updating the system software of the activation terminal 10) or read data (such as reading the fault code read from the target vehicle and cached locally by the activation terminal 10, or the matching record stored locally by the activation terminal 10, etc.). Transmitting the above data in a wired form can avoid abnormalities such as data loss or read and write failures that may be caused by wireless transmission, thereby improving the success rate of data interaction between the two.

[0070] In one embodiment, the power module 15 is used to supply power to various modules (other than the power module 15). For example, the power module 15 is connected to the control module 13 and can therefore directly supply power to the control module 13. For another example, since the control module 13 is connected to the first antenna module 11 and the second antenna module 12, the power module 15 can also indirectly supply power to the first antenna module 11 and the second antenna module 12 through the control module 13. This application does not limit the specific power supply method.

[0071] The power module 15 includes a battery, which can be a disposable battery (such as a button cell or a cylindrical battery such as AA or AA), or a rechargeable battery that can be charged and discharged multiple times, thereby extending the battery life of the activation terminal 10 and reducing maintenance. Furthermore, if the battery is a disposable battery, it can be removable to facilitate user replacement. If the battery is a rechargeable battery, it can be removable for maintenance or non-removable to increase the compactness of the activation terminal 10, thereby facilitating miniaturization.

[0072] If the battery is a rechargeable battery, the OBD interface 14 may also be connected to the power module 15 so that the target vehicle can charge the battery via the power pin of the OBD interface. Alternatively, the data interface module 16 may also be connected to the power module 15 so that the data management device can charge the battery via the power pin of the data interface. The other end of the physical connection cable may also be directly connected to the power output interface to directly charge the rechargeable battery.

[0073] In one embodiment, the activation terminal may further include an operation sensing module that can be used to sense preset operations performed by the user on the activation terminal. For example, the operation sensing module can be a physical button, a physical lever, etc. For example, when the activation terminal detects a single press of the button by the user, it can respond to this operation by writing the target communication parameters of the target vehicle to the tire pressure sensor via NFC connection, thereby achieving "one-click writing" of the target communication parameters, which helps improve user operation convenience and overall matching efficiency.

[0074] In one embodiment, the activation terminal may further include a status output module, which may be used to output the operating status information of the activation terminal. Exemplarily, the status output module may be an LED, a buzzer, a vibration motor, etc. Taking the LED 23 shown in FIG2 as an example, during the process of the activation terminal 10 writing the target communication parameters of the target vehicle to the tire pressure sensor via the NFC connection, the LED 23 may flash rapidly; and may stop flashing after the writing is completed. For another example, during the process of the data interface 24 being connected to the power output interface and charging the rechargeable battery inside the activation terminal 10 via the connection, the LED may maintain a color (such as red) that is always on, and change color (such as to green) to be always on or directly off after being fully charged.

[0075] In one embodiment, the surface of the activation terminal 10 housing may also be provided with anti-slip grooves 25 to prevent the device from slipping and being damaged when the user holds the terminal. In addition, to improve the user's grip and user experience, the shape of the activation terminal 10 housing may also be configured to better suit the user's grip posture, which will not be further described.

[0076] It is worth noting that the appearance of the activation terminal shown in Figure 2 is only exemplary. In practical application, the relative positions of the various interfaces and sensing areas contained in the terminal can be reasonably set according to actual conditions, and this application does not impose any restrictions on this.

[0077] This concludes the introduction to the structure and functions of the activation terminal. Based on the activation terminal, this application also proposes a tire pressure sensor activation system, which includes an activation terminal, a tire pressure sensor, a target vehicle, and an electronic device running an activation client. The tire pressure sensor is used to be installed on a target tire of the target vehicle, wherein:

[0078] The activation client is configured to instruct the activation terminal to write the target communication parameters of the target vehicle into the tire pressure sensor;

[0079] The activation terminal is configured to send the target sensor identifier of the tire pressure sensor to the target vehicle under the instruction of the electronic device after establishing a connection with the target vehicle through the OBD interface;

[0080] The tire pressure sensor is used to submit the status-related data of the target tire to the target vehicle according to the written target communication parameters after installation is completed. The status-related data includes the target sensor identifier and the tire status data collected by the tire pressure sensor.

[0081] It should be noted that the activation process of the tire pressure sensor includes a programming phase and a learning phase. In the programming phase: the activation client instructs the activation terminal to write the target communication parameters into the tire pressure sensor (that is, the activation terminal writes the target communication parameters into the tire pressure sensor under the instruction of the activation client); in the learning phase: the activation terminal sends the target sensor identifier of the tire pressure sensor to the target vehicle under the instruction of the electronic device. After the above-mentioned programming and learning phases are completed, the activation process of the tire pressure sensor is completed. Thereafter, the tire pressure sensor can cooperate with the target vehicle to start normal operation, that is, for the tire status data collected by itself, the sensor can send status-related data including the target sensor identifier and the tire status data to the target vehicle according to the target communication parameters written locally, so that the target vehicle can receive and identify it.

[0082] As shown in Figure 3, the activation system 30 includes a mobile phone 31, an activation terminal 10, a tire pressure sensor 32 and a target vehicle 33. Among them, the mobile phone 31, an electronic device, runs an activation client (which can be in the form of an APP, a web application or a small program, etc.), and the electronic device can establish a wireless connection with the activation terminal 10 (that is, the first wireless connection of this application, such as a Bluetooth connection or a Wi-Fi connection); the activation terminal 10 can also establish a wireless connection with the tire pressure sensor 32 (that is, the second wireless connection of this application, such as an NFC connection or a wireless radio frequency connection), and the mobile phone 31 can also establish a wireless connection with the tire pressure sensor 32 (such as an NFC connection, etc., which is not shown in the figure). It can be seen that the electronic devices, tire pressure sensors and activation terminals in the system can interact with each other through wireless connections. In addition, the tire pressure sensor 32 and the target vehicle 33 can communicate through a wireless radio frequency connection. For example, the tire pressure sensor 32 can transmit radio frequency broadcast signals in the form of FSK (Frequency Shift Keying), ASK (Amplitude Shift Keying), PSK (Phase Shift Keying), etc. to the surrounding space. Of course, the target vehicle 33 itself should be equipped with a communication antenna to achieve this wireless connection with the tire pressure sensor. It should be noted that the wireless connection established between any two parties mentioned above is actually an end-to-end connection between the two parties. In fact, it is precisely because the various devices in the activation system can interact based on the above-mentioned wireless connection that the system can achieve the expected function of matching the tire pressure sensor without special connecting lines, thereby simplifying the system structure and helping to reduce costs. Of course, the activation terminal 10 can establish a wired connection with the target vehicle 33 through the OBD interface, which will not be repeated here.

[0083] For example, in the activation system, communication (i.e., data interaction) can be achieved between the target vehicle and the tire pressure sensor through the aforementioned wireless radio frequency connection; the first wireless connection between the electronic device and the activation terminal can be a Bluetooth connection or a WiFi connection; the second wireless connection between the activation terminal and the tire pressure sensor can be an NFC connection or a wireless radio frequency connection. In addition, a wireless connection such as an NFC connection or a wireless radio frequency connection can also be established between the electronic device and the tire pressure sensor for data interaction. Of course, the specific forms of the above-mentioned connections can also be reasonably set according to actual conditions, and this application does not limit this.

[0084] Among them, the mobile phone 31 is just one type of electronic device that the user can use. In fact, the user can use any electronic device with wireless connection function. Exemplarily, the electronic device can also be: a tablet device, a laptop computer, a PDA (Personal Digital Assistant), a wearable device (such as smart glasses, smart watches, etc.), a VR (Virtual Reality) device, an AR (Augmented Reality) device, etc., and one or more embodiments of this specification are not limited to this. The mobile phone 31 can run a client program that activates the client. Exemplarily, the client program can be an APP (Application), a web application (or web page) implemented based on a browser, or a mini program (Mini program) implemented based on other applications. Among them, the APP usually needs to be pre-installed and started; and the web application and mini program can be an online "client" built using HTML5 technology. The operation of this type of client program usually does not require a specific "installation" step, but is integrated into the browser or other application as an independent page or functional component (or plug-in) to run. This is hereby explained. The activation client can provide the user with an operable human-machine interface, based on which the user can perform corresponding operations in the human-machine interface to implement the activation method described below. In fact, because the electronic device can display the human-machine interface for user operation, the activation terminal itself does not need to be equipped with a display component such as a screen, thereby simplifying the terminal's hardware structure and software logic, and facilitating the miniaturization of the terminal.

[0085] In addition, the activation system 30 may also include a server 36 deployed in the cloud. Corresponding to the activation client running on the mobile phone 31, the server 36 may run a corresponding activation server. The mobile phone 31 may obtain the target communication parameters of the target vehicle 33 from the server 36 based on the vehicle model information of the target vehicle 33. After the tire pressure sensor 32 is activated, relevant data of the activation process (hereinafter referred to as activation-related data) may be uploaded to the server 36 for efficient storage and management of the activation-related data in the cloud. The server 36 may be a physical server containing an independent host, or a virtual server hosted by a host cluster, a cloud server, etc., and this application is not limited thereto.

[0086] As previously mentioned, the tire pressure sensor 32 described in the present application has the function of establishing a wireless connection. In addition to being able to send wireless radio frequency signals to the target vehicle 33, it can also establish a second wireless connection in the form of an NFC connection with the activation terminal 10. The embodiment of the present application does not limit the brand, size, installation location, specific communication method, etc. of the tire pressure sensor 32. Similarly, the target vehicle 33 described in the present application can receive the wireless radio frequency signal sent by the tire pressure sensor 32, and can establish a wired connection with the activation terminal 10 through the OBD interface installed on it. The embodiment of the present application does not limit the brand, model, number of tires, specific communication method, etc. of the target vehicle 33.

[0087] This concludes the introduction to the activation system. Based on the aforementioned activation system, this application also proposes a method for activating a tire pressure sensor used in the system. It is understood that this method requires the coordination of various devices in the system to implement.

[0088] Figure 4 is a flow chart illustrating a tire pressure sensor activation method according to an exemplary embodiment of this specification. As shown in Figure 4 , this method is applied to an activation system. As previously described, the system includes an electronic device, an activation terminal, a tire pressure sensor, and a target vehicle. The tire pressure sensor is mounted on a target tire of the target vehicle. The method may include the following steps 402-406.

[0089] Step 402: The activation client instructs the activation terminal to write the target communication parameters into the tire pressure sensor.

[0090] The tire pressure sensor described in this application is a sensor that needs to be installed on a target tire of a target vehicle. The target vehicle can be equipped with at least one tire, and the target tire can be any of the tires. The tire can be a brand new tire pressure sensor or a used tire that has been repaired (such as a tire patch). The tire pressure sensor can be a brand new tire pressure sensor that has never been used, or it can be a used tire pressure sensor removed from the target tire, the tire before the target tire (that is, the target tire is used to replace the previous tire), other tires of the target vehicle, or any tire of other vehicles (but its function is normal and can still be activated and used). This solution can be applied to the production stage or the maintenance stage of the target vehicle. For example, in the production stage, the tire pressure sensor to be installed can be a brand new sensor. Before installation, no tire pressure sensor has been installed in the target tire and the tire pressure sensor to be installed has not been used. In the maintenance stage, the tire pressure sensor to be installed can be a brand new sensor or a sensor that has been used but not damaged (still can be activated and used). The target tire can be a used tire that has been repaired or a brand new tire that has been installed (to replace a faulty old tire).

[0091] In addition, the user described in this application may be a production personnel who produces (or assembles) the target vehicle, the owner of the target vehicle, or the maintenance personnel of the target vehicle (such as employees of a 4S store or maintenance point, etc.). The user can run the aforementioned activation client in the electronic device he uses, such as installing the client APP and starting to run the APP, or opening a browser and logging in to the client page, etc. After logging in to the activation client, based on the human-computer interaction interface provided by the client, the user can start activating the tire pressure sensor.

[0092] To further reduce the user's operational threshold and learning cost, the activation client can display guidance information such as animations, text, or images illustrating the activation process to the user, so that the user can quickly master the operation. Of course, the above guidance information can also be displayed only during the user's first login or the first few logins to minimize the information display burden on the activation client and avoid interference with experienced users.

[0093] Since the wireless communication protocols used by vehicles of different brands, models, and even batches are often different, in order to ensure that the tire pressure sensor can communicate smoothly with the target vehicle, the target communication parameters of the target vehicle need to be written into the tire pressure sensor first. The parameters may include target connection parameters (including the protocol stack of the communication protocol, version number, field meaning of the data message, data encryption method, etc.). In addition, the target communication parameters may also include target submission configuration parameters, which are used to specify the submission method of tire status data (such as submission cycle, maximum interval duration, etc.) - this method can be recognized and approved by the target vehicle, so that the activated tire pressure sensor can submit its collected tire status data to the target vehicle normally in this way. It can be seen that the target communication parameters are used to indicate (or inform) the tire pressure sensor how to submit status-related data to the target vehicle - the tire pressure sensor submits the status-related data to the target vehicle in the manner indicated by the parameters, and the data can be successfully received and recognized by the target vehicle.

[0094] In one embodiment, the activation client can use a variety of methods to instruct the activation terminal to write the target communication parameters into the tire pressure sensor. For example, the activation client can first obtain the target communication parameters of the target vehicle, and send a parameter write instruction containing the parameter to the activation terminal to instruct the activation terminal (through the instruction) to write the target communication parameters into the tire pressure sensor. At this time, the activation client obtains the target communication parameters by itself and provides them to the activation terminal, which helps to make full use of the relatively strong data processing capabilities of the electronic device and simplifies the processing logic of the activation terminal. Alternatively, the activation client can also first determine the parameter indication information of the target communication parameters, and then send a determination and write instruction containing the information to the activation terminal to instruct the activation terminal (through the instruction) to determine the target communication parameters based on the information and write them into the tire pressure sensor. At this time, the activation client instructs the activation terminal to obtain and write the target communication parameters, which helps to simplify the user's operations at the activation client.

[0095] The activation client can obtain the target communication parameters of the target vehicle in a variety of ways. In one embodiment, when a third wireless connection (such as Bluetooth or Wi-Fi) is established between the electronic device and the target vehicle, the activation client can request and obtain the target communication parameters of the target vehicle through the wireless connection. The parameters can be pre-stored locally by the vehicle (such as written locally when the vehicle leaves the factory) or temporarily generated in response to the aforementioned request, etc., which will not be repeated here.

[0096] In another embodiment, when a fourth wireless connection (not shown in the figure, it can be an NFC or radio frequency connection, etc.) is established between the electronic device and an activated tire pressure sensor installed and activated on any tire of the target vehicle, the activation client can also read the communication parameters written into the activated tire pressure sensor through the wireless connection. Because the activated tire pressure sensor has been activated (that is, the sensor has uploaded its own collected status-related data to the target vehicle), it means that it can communicate smoothly with the target vehicle using the communication parameters written into it. Therefore, writing the communication parameters as target communication parameters into the tire pressure sensor that needs to be replaced this time can ensure that the sensor can also communicate smoothly with the target vehicle after activation. The activated tire pressure sensor can be a sensor that is working on a normal tire of the target vehicle, or it can be an old tire pressure sensor removed from the vehicle.

[0097] In another embodiment, given that different models of vehicles often have their own different communication parameters, when determining the target communication parameters, the activation client can respond to the vehicle model designation operation performed by the user and determine the target communication parameters that match the target vehicle model information of the designated target vehicle.

[0098] Among them, the target vehicle model information is one or a group of information that can characterize the vehicle model of the target vehicle. This information is used to determine the target communication parameters of the target vehicle, which may include but is not limited to brand, model, year, batch, etc. Among them, the activation client can determine the target vehicle model information in a variety of ways. For example, if the user of the activation client already knows the vehicle model of the target vehicle (such as checking the vehicle body appearance or consulting the vehicle information manual, etc.), then he or she can directly specify the corresponding target vehicle model information in the activation client. For example, the activation client can display an information input box, and the user enters his or her target vehicle model information in the information input box according to the actual situation of the target vehicle, so that the activation client can obtain the information. Alternatively, the activation client can also display multiple alternative vehicle model information to the user in the form of a list, and the user can browse the list, find (if necessary, enter a keyword search) and select the vehicle model information that meets the actual situation of the target vehicle, and the activation client can determine the information as the target vehicle model information. For example, the activated client can display multiple alternative brands to the user. After the user selects brand A, the various alternative models of the brand are displayed; after the user further selects model type B, the various years of the model and their corresponding target communication parameters are displayed; and after the user selects year C, the target communication parameters corresponding to the year are determined as the target model information of the target vehicle.

[0099] For another example, given that the electronic device where the activation client is located can exchange data with the target vehicle (i.e., the aforementioned third wireless connection can be established between the two), the activation client can also directly obtain its target vehicle model information from the target vehicle. For example, when the electronic device and the target vehicle have established a third wireless connection, the activation client can request and obtain its target vehicle model information from the target vehicle through the wireless connection. In this way, the target vehicle itself provides its target vehicle model information to the activation client. This process does not require the user to participate in information input or correction, which helps to avoid information errors that may be caused by human factors and improves the accuracy of the obtained target vehicle model information.

[0100] After determining the target vehicle model information, the activation client can further determine the target communication parameters that match the information in a variety of ways. For example, relevant personnel can pre-compute the vehicle model information and communication parameters of various vehicles, and create a vehicle model parameter table to record the correspondence between the vehicle model information and communication parameters of various vehicles. The communication parameters of any vehicle can include only its connection parameters, or can also include its connection parameters and submission configuration parameters. The vehicle model parameter table can be maintained locally by the electronic device (such as maintained as a configuration file of the activation client), or it can be maintained locally by the activation server associated with the activation client (which can run in the server 36 shown in Figure 1), or it can be pre-written to the activation terminal and maintained by it, etc.

[0101] If the electronic device has a vehicle model parameter table stored locally, the activation client can query the target communication parameters corresponding to the target vehicle model information (determined in the above embodiment) from the vehicle model parameter table stored locally in the electronic device. In this way, the target communication parameters can be determined as quickly as possible through local query without the need for data interaction with other devices, and the query speed is relatively fast. Of course, given that parameters such as protocol stacks usually have a large amount of data, in order to save local storage space of the data electronic device, the vehicle model parameter table it maintains can also only record the correspondence between the vehicle model information and the identifier of its target communication parameter (rather than the target communication parameter itself). Therefore, after the activation client queries the identifier of the target communication parameter from the table in the above manner, it can send the identifier to the activation server to obtain the target communication parameter (represented by the identifier) ​​returned by it. If the above server has a vehicle model parameter table stored locally, the activation client can initiate a parameter acquisition request containing the above target vehicle model information to the pre-associated activation server, so that the activation server can respond to the request by querying the target communication parameter corresponding to the target vehicle model information in the vehicle model parameter table maintained by itself, and return the queried parameter to the activation client; and the activation client can receive the parameter returned by the activation server. In this way, the electronic device does not need to save the vehicle model parameter table locally and perform query operations, which saves the local storage space of the electronic device and simplifies its local processing logic, helping to achieve lightweight activation client. In the case where the aforementioned vehicle model parameter table is maintained by the activation server, if the network performance of the electronic device is poor, the vehicle can be instructed to access the activation client to obtain the target communication parameters and return them to the activation client, thereby utilizing the vehicle's own powerful cloud access capabilities to ensure that the electronic device obtains the parameters. As mentioned above, after obtaining the aforementioned target communication parameters, the activation client can send a parameter write instruction containing the target communication parameters to the activation terminal to instruct the activation terminal to write the target communication parameters to the tire pressure sensor.

[0102] In addition, in an embodiment where the activation client instructs the activation terminal to obtain and write the target communication parameters, the activation terminal can query the target communication parameters corresponding to the target vehicle model information from the vehicle model parameter table locally stored in the activation terminal if it maintains the aforementioned vehicle model parameter table.

[0103] As previously mentioned, the activation client can send a parameter write instruction containing the target communication parameters to the activation terminal to instruct the latter to write the parameters to the tire pressure sensor. The activation client can implement this instruction in a variety of ways. For example, when the electronic device successfully establishes a first wireless connection (such as a Bluetooth connection) with the activation terminal, the activation client can respond to a first sending operation performed by the user (such as clicking the "Send Parameters" virtual control in the activation interface of the activation client) and send a write instruction containing the target communication parameters to the activation terminal via the first wireless connection to instruct the activation terminal to write the target communication parameters to the tire pressure sensor via the second wireless connection in response to the detected first write operation. Thereafter, the user can perform a first write operation on the activation terminal at an appropriate time (i.e., perform this operation on the operation perception module installed on the activation terminal, such as clicking the physical button of "Confirm Write") to trigger the activation terminal to write the target communication parameters to the tire pressure sensor via the second wireless connection (such as the NFC connection) in response to this operation.

[0104] For another example, when the electronic device successfully establishes a first wireless connection with the activation terminal, the activation client can, in response to a second sending operation performed by the user, send the target communication parameters to the activation terminal via the first wireless connection. After receiving the parameters, the activation terminal can cache them locally. Thereafter, the user can perform a second write operation on the activation client at an appropriate time (e.g., clicking a "Start Writing" virtual control). At this time, the activation client, in response to this operation, sends a write instruction for the aforementioned target communication parameters (which have already been sent) to the activation terminal, instructing the activation terminal to write the target communication parameters to the tire pressure sensor via the second wireless connection. In this manner, the sending process of the target communication parameters to be written (i.e., the activation client sends the parameters to the activation terminal) and the writing process (i.e., the activation terminal writes the parameters to the tire pressure sensor) are separated. This allows the user to instruct the target communication parameters to be sent to the activation terminal for caching first, and then, at an appropriate time, directly trigger the writing by operating the physical module of the activation terminal or by operating the virtual control in the interactive interface of the activation client to trigger the writing. This can meet the diverse operational needs or habits of users in tire pressure sensor matching scenarios (especially vehicle maintenance) and can smoothly write the target communication parameters regardless of whether the tire pressure sensor is installed or not.

[0105] For another example, if the electronic device successfully establishes a first wireless connection with the activation terminal and the activation terminal successfully establishes a second wireless connection with the tire pressure sensor, the activation client may also, in response to a user's third write operation for the target communication parameters, send a write instruction containing the target communication parameters to the activation terminal via the first wireless connection, instructing the activation terminal to write the parameters to the tire pressure sensor via the second wireless connection. In this case, the write instruction sent by the electronic device to the activation terminal has the dual functions of "sending the target communication parameters" and "instructing the writing of the target communication parameters." This approach is particularly suitable for writing the target communication parameters before installing the tire pressure sensor. Still using Figures 2 and 3 as an example, the user can establish a Bluetooth (or WiFi) connection (or connection) between the mobile phone 31 and the activation terminal 10, and then place the NFC sensing surface of the tire pressure sensor 32 within the NFC sensing area on the back of the mobile phone 31. Then, the user can click the "Start Writing" virtual control on the interface of the mobile phone 31. In response to this operation, the activation client on the mobile phone 31 sends a parameter write instruction containing the target communication parameters to the activation terminal 10, and the activation terminal 10, in response to this instruction, writes the target communication parameters to the tire pressure sensor 32.

[0106] In one embodiment, after obtaining the target communication parameters of the target vehicle, the activation client can instruct the activation terminal to write these parameters to the tire pressure sensor to be activated at various times. For example, before beginning installation of the tire pressure sensor, a parameter write instruction containing the target communication parameters can be sent to the activation terminal, instructing the activation terminal to write the target communication parameters to the tire pressure sensor. Accordingly, the activation terminal can attempt to write the target communication parameters to the tire pressure sensor in response to the instruction and provide feedback (successful or unsuccessful) on the write result to the activation client. If the target communication parameters are successfully written, the activation client can output a message to the user prompting the user to begin installation. Specifically, the installation prompt message can be displayed in any form, such as displaying text or images, playing a voice message, or flashing an indicator light. For example, text such as "Parameters written successfully, please begin tire pressure sensor installation" or "Written successfully, please install sensor" can be displayed in a pop-up message window on the client. For another example, the activation client can also instruct the activation terminal to write the target communication parameters to the tire pressure sensor after the tire pressure sensor is installed. For example, a write trigger instruction containing the target communication parameters can be sent to the activation terminal to trigger the writing of the parameters. Because the tire pressure sensor has been installed on the target vehicle at this time, even if the writing is confirmed to be successful, the activation client does not need to display the aforementioned installation start prompt message, but can only display the writing success notification message (such as "writing successful" and other text).

[0107] Among them, whether the activation client triggers the activation terminal to write the target communication parameters before starting to install the tire pressure sensor, or triggers the activation terminal to write the target communication parameters after the installation is completed, can be decided by the user; alternatively, the user can also perform corresponding operations in the activation client according to the actual installation situation, such as clicking on virtual controls such as "Not yet installed" or "Installed" to enter the write trigger page, and trigger the activation terminal to write the target communication parameters on this page. Of course, because the electronic device may not be able to know whether the tire pressure sensor has been successfully installed on the target tire, the activation client can directly output the aforementioned installation start prompt message when it determines that the write is successful (it has written successfully itself or received a write success message from the activation terminal), so that the user can decide whether to install the tire pressure sensor.

[0108] It should be noted that, depending on the working mode of the tire pressure sensor, the sensor can be installed in an internal manner (i.e., the tire pressure sensor is installed on the inner wall of the target tire) or an external manner (i.e., the tire pressure sensor is screwed to the outside of the valve stem of the target tire). This application does not limit the installation method of the sensor.

[0109] At this point, the target communication parameters of the target vehicle are successfully written to the tire pressure sensor (the tire pressure sensor can then use these parameters to establish a wireless connection with the target vehicle for submitting status-related data), and the programming phase of the activation process is completed.

[0110] Step 404 : After establishing a connection with the target vehicle through the on-board diagnostic system (OBD) interface, the activation terminal sends the target sensor identifier of the tire pressure sensor to the target vehicle under the instruction of the activation client.

[0111] The activation terminal needs to determine the target sensor identifier of the tire pressure sensor and send it to the target vehicle so that the target vehicle can subsequently determine, based on the identifier, which tire the status-related data it receives comes from.

[0112] In one embodiment, the activation terminal can obtain the target sensor identifier in a variety of ways. For example, the tire pressure sensor can be pre-written with its own original sensor identifier (e.g., during the sensor production stage, the manufacturer assigns a unique original sensor identifier to each sensor and writes it into the sensor's local storage space. This original sensor identifier can serve as the unique identifier of the sensor throughout its life cycle). In this regard, the tire pressure sensor can send its own original sensor identifier to the activation terminal, and the latter can determine the received identifier as the target sensor identifier. In this way, the activation terminal can easily and quickly obtain the target sensor identifier, and the acquisition logic is simple and efficient.

[0113] In another embodiment, since the tire pressure sensor installed during the maintenance phase of the target vehicle may not be an original accessory of the vehicle, in order to avoid multiple tire pressure sensors with the same original sensor identifier produced by different brands or different manufacturers being installed in the same vehicle, causing the vehicle to be unable to effectively distinguish between different sensors, the target sensor identifier can also be generated based on the basic information of the tire pressure sensor. For example, the activation terminal can receive the basic information of the tire pressure sensor sent by the tire pressure sensor. The basic information may include factory information such as the brand, model, batch, etc. of the sensor, software information such as firmware version, memory space, and / or hardware information such as chip model. This application is not limited to this. In addition, the user can specify the target location information corresponding to the expected installation location of the tire pressure sensor to be activated on the target vehicle (i.e., the location of the target tire on the target vehicle) in the activation client, so that the activation client can send this information to the activation terminal. Based on this, the activation terminal can generate the target sensor identifier based on the basic information and target location information when receiving the basic information sent by the tire pressure sensor and the target location information sent by the activation client. Among them, the target position information of the target tire can be specified by the user in the interactive interface of the activation client according to the actual position of the target tire, such as "left front", "right front", "left rear", "right rear", etc. In this way, even if the basic information of the tire pressure sensors installed on different tires of the target vehicle is the same, different sensor identifiers can still be generated for them based on different position information, thereby avoiding identifier conflicts. In fact, the activation terminal can also generate the target sensor identifier only based on the above-mentioned position information, and even assign different simple numbers (such as 1, 2, 3, etc.) to each tire pressure sensor installed on the target vehicle as their respective sensor identifiers. The embodiments of the present application are not limited to this.

[0114] In another embodiment, the target sensor identifier can also be sent by the activation client to the activation terminal, so that the activation terminal can receive the target sensor identifier sent by the activation client. In addition to being used to send the target sensor identifier to the vehicle through the OBD interface, the target sensor identifier also needs to be written to the tire pressure sensor. Among them, the client can obtain the target sensor identifier from other devices (such as the cloud), or it can also generate the target sensor identifier by itself. Exemplarily, after receiving the aforementioned basic information sent by the tire pressure sensor, the activation terminal can forward the information to the activation client, so that the activation client can generate the target sensor identifier based on the basic information and the target position information of the target tire, and return the identifier to the activation terminal.

[0115] The tire pressure sensor may send the original sensor identifier or the basic information to the activation terminal at different times. For example, the original sensor identifier or the basic information may be sent in response to receiving the target communication parameter (written by the electronic device or the activation terminal); or the original sensor identifier or the basic information may be returned to the activation terminal in response to an identifier acquisition instruction sent by the activation terminal.

[0116] In addition, when the activation terminal or the activation client generates the target sensor identifier based on the basic information and the target location information, the calculation can be performed in a variety of ways. For example, the hash value of the basic information and the target location information can be calculated, and the hash value can be used as the target sensor identifier. Alternatively, the target vehicle-related information of the target vehicle collected by the activation client can be obtained, and the target sensor identifier can be generated based on the basic information, the target location information and the target vehicle-related information. Among them, the target vehicle-related information can be the factory information or software and hardware information of the vehicle itself, or it can be the owner's authorization information (such as a verification code or password provided by other electronic devices used by the owner). By introducing the target vehicle-related information, it can be ensured that the generated target sensor has a one-to-one correspondence with the target vehicle, thereby binding the tire pressure sensor and the target vehicle to prevent the sensor from being maliciously replaced or the target vehicle from receiving tire status data uploaded by tire pressure sensors installed on other nearby vehicles.

[0117] It should be noted that no matter what method the activation terminal uses to determine the target sensor identifier, the format of the identifier must comply with the identifier encoding rules corresponding to the aforementioned target communication parameters to ensure that the identifier can be successfully recognized by the target vehicle. For example, in the case where the target sensor identifier is the aforementioned original sensor identifier, when the activation client determines the target communication parameters, it should determine them from the various communication parameters corresponding to the identifier encoding rules of the original sensor identifier. For another example, in the case where the target sensor identifier is generated by the activation client (or activation terminal), it can first determine the identifier encoding rules corresponding to the target communication parameters, and then generate the target sensor identifier according to an algorithm that complies with the rules. This will not be repeated here.

[0118] In one embodiment, a user can connect the terminal to a vehicle by activating the terminal's built-in OBD interface, i.e., by inserting the terminal into the vehicle's OBD interface to establish a wired connection between the two. After the connection is established, the activating terminal can, under the instruction of the electronic device, transmit the target sensor identifier obtained in the aforementioned manner to the target vehicle, so that the target vehicle can subsequently identify the specific tire pressure sensor from which the status-related data it receives comes based on the identifier.

[0119] In one embodiment, the activation terminal may send the correspondence between the target sensor identifier of the tire pressure sensor and the target position information of the target tire to the target vehicle under the instruction of the activation client. Particularly, after obtaining the target position information of the target tire specified by the user, the activation client may send the information to the activation terminal. If the activation terminal obtains the original sensor identifier or the activation terminal calculates the target sensor identifier, the activation client may send the target position information alone to the activation terminal; and in the case where the activation client calculates the target sensor identifier, it may send the target sensor identifier and the obtained target position information together to the activation terminal (such as included in the same message), so that the activation terminal can determine the correspondence between the two accordingly. The specific process of the activation terminal sending the correspondence between the target sensor identifier and the target position information through the connection established by the OBD interface can be found in the records of the relevant embodiments, and the embodiments of the present application are not limited to this.

[0120] After receiving the correspondence between the target sensor identifier and the target location information sent by the activation terminal, the target vehicle can locally maintain this correspondence so as to subsequently determine which tire's tire status data was received. It should be noted that at least one tire pressure sensor can be installed on any tire of the target vehicle, and the vehicle can maintain the correspondence between the location information of each tire and the sensor identifiers of all tire pressure sensors installed on it.

[0121] At this point, the target sensor identifier of the tire pressure sensor is successfully sent to the target vehicle, and the learning phase of the activation process is completed.

[0122] Step 406: The installed tire pressure sensor submits the target tire status data to the target vehicle according to the written target communication parameters. The status data includes the target sensor identifier and the tire status data collected by the tire pressure sensor.

[0123] After the activation client or activation terminal writes the target communication parameters of the target vehicle into the tire pressure sensor, the sensor can submit the status-related data of the target tire to the target vehicle according to the parameters after being installed.

[0124] In one embodiment, the tire pressure sensor may submit data related to the target tire's status in one of the following ways. For example, the target tire's status data may be submitted in response to the successful writing of the target connection parameters. If the tire pressure sensor is not yet installed when the target communication parameters are written, the parameters may be written via NFC or Bluetooth. If the tire pressure sensor is already installed when the target communication parameters are written, the parameters may be written via Bluetooth (due to the limited signal transmission range of NFC, which makes it difficult to establish an NFC connection with an installed tire pressure sensor). For another example, if the target connection parameters are successfully written, the target tire's status data may be submitted in response to a work trigger instruction sent by the activation terminal, i.e., the activation terminal triggers the tire pressure sensor to begin submitting data. For another example, if the target connection parameters are successfully written, the target tire's status data may be submitted in response to receiving a radio frequency wake-up signal sent by the target vehicle, i.e., the target vehicle actively wakes up the tire pressure sensor to submit data. For another example, given that the target tire is typically pressurized (i.e., inflated) after the tire pressure sensor is installed, the tire pressure sensor may also begin submitting current status data for the first time when it first detects that the pressure reaches the activation pressure threshold. For another example, given that the target vehicle usually starts driving after the tire pressure sensor is installed (the installed sensor will detect a large acceleration for the first time), the tire pressure sensor can also start submitting current status-related data for the first time when it first detects that the acceleration reaches the activation acceleration threshold, which will not be repeated here.

[0125] As can be seen from the above embodiments, this solution can, through the mutual cooperation of the various devices in the activation system, on the one hand, send the target sensor identification of the tire pressure sensor to the target vehicle so that the target vehicle can recognize the sensor (i.e., the learning process); on the other hand, it can write the target communication parameters of the target vehicle into the tire pressure sensor (i.e., the programming process) so that the tire pressure sensor can send status-related data according to the parameters and be successfully recognized by the target vehicle. After the tire pressure sensor installed in the target tire collects the tire status data of the tire, it can send tire status data containing the target sensor identification and the tire status data to the target vehicle, so that the target vehicle can identify the tire status data from the tire pressure sensor (rather than the tire pressure sensors installed on other tires) based on the target sensor identification and perform subsequent processing such as displaying or judging the data. It can be seen that the activation system described in this solution can implement a complete activation process for the tire pressure sensor, including programming and learning, to ensure that the tire pressure sensor can work normally with the target vehicle after installation.

[0126] In addition, the aforementioned activation system consists of a tire pressure sensor, a target vehicle, an activation terminal, and an electronic device, while only conventional electronic devices are introduced in comparison to the related art solutions. Specifically, compared to the special tools used in the related art, the activation terminal in the activation system can connect to the target vehicle via its own OBD interface and wirelessly connect to the electronic device and tire pressure sensor via a built-in antenna module. This eliminates the need for expensive equipment (such as dedicated learning tools, VCI devices, or special connection cables), significantly reducing the hardware cost of the activation system. Furthermore, because the newly introduced electronic device can be a conventional electronic device such as a mobile phone or tablet computer, and these devices already have display functions and a rich human-machine interface, based on the electronic device and wireless connection, the user only needs to perform simple operations in the electronic device's operating interface to control the activation terminal. This not only reduces the user's operation and usage threshold, but also effectively simplifies the activation terminal's hardware structure and software logic, contributing to the miniaturization, portability, and minimalist operation of the activation terminal. Thus, the activation system described in this application achieves lightweight and miniaturization of the activation terminal by controlling the activation terminal through the electronic device, thereby reducing the hardware cost and usage cost of the tire pressure sensor activation process, significantly reducing costs and increasing efficiency.

[0127] In one embodiment, the target communication parameters may also include target submission configuration parameters, such as the submission period and the maximum interval between submissions. Based on this, the installed tire pressure sensor can submit the target tire status data to the target vehicle using the submission method specified by the target submission configuration parameters. Because the target submission configuration parameters correspond to the aforementioned target vehicle model information, the submission method specified by these parameters can be considered the submission method specified by the target vehicle. Therefore, the target vehicle can successfully recognize the status data submitted using this recognition method, minimizing the possibility of vehicle failure.

[0128] It is understood that the target sensor identifier in the status-related data can be used to specify the sender of the status-related message to the vehicle. That is, the vehicle can determine which tire pressure sensor installed on its tire originated the data based on the target sensor identifier contained in the status-related data. For example, after receiving status-related data from a tire pressure sensor installed on a particular tire, the target sensor identifier contained in the data can be extracted and the location information corresponding to the target sensor identifier can be queried based on the locally maintained correspondence between the aforementioned sensor identifier and the tire's location information. This location information can then be used to characterize the tire's identity. In addition, the status-related data may also include the tire pressure sensor's own status data, such as the remaining battery level, which will not be further described.

[0129] The tire status data collected by the tire pressure sensor can be used to characterize the current status of the target vehicle. Exemplarily, the tire status data may include at least one of the following: tire pressure data, tire temperature data, tire acceleration data, etc. Which data the tire status data specifically includes is determined by the sensing element installed inside the tire pressure sensor, and the embodiments of the present application do not limit this. To facilitate the user's perception of the tire status, the vehicle can display the tire status data on the instrument panel or central control screen, such as displaying "the current tire pressure of the left front wheel is 2.3 Bar", "the current temperature of the right front wheel is 30°C", etc. in the form of text, pictures or animations. Of course, in order to further reduce the difficulty of user understanding and improve driving safety, the target vehicle can also determine whether the current status of the target tire is normal based on the above tire status data, and send a warning message to the user when it is in an abnormal state (such as too low tire pressure, too high temperature, etc.).

[0130] If the target vehicle's status data transmitted by the tire pressure sensor is correctly recognized by the target vehicle, the tire pressure sensor and the target vehicle are successfully matched, and the matching process for the tire pressure sensor is completed. For example, the maintenance operation on the target tire can be completed. Thereafter, while the target vehicle is in operation, the tire pressure sensor can automatically submit the target vehicle's status data to the target vehicle using the aforementioned submission method.

[0131] In one embodiment, the electronic device may upload the matching-related data involved in the above-mentioned matching process to the server for maintenance and management. The matching-related data may include the relevant data of the tire pressure sensor (such as the target sensor identification, brand, manufacturer, price, etc.), the relevant data of the vehicle (such as the vehicle brand, model, owner information, etc.), and the relevant data of the user (such as the user name logged in by the client program of the electronic device, the time and place of this matching, etc.). The server can provide services for electronic devices used by multiple users. After obtaining the relevant data uploaded by each electronic device, data management and mining can be performed based on these data from multiple dimensions such as brand (of the vehicle or tire pressure sensor), repair shop, and user, so as to achieve efficient management and data reuse of massive data.

[0132] In one embodiment, because the activation terminal can be connected to the target vehicle through the OBD interface, and the OBD interface has rich vehicle data interaction functions, the activation terminal can also integrate the function of collecting vehicle status data. For example, the activation terminal can collect the target vehicle status data (such as fault codes, operation logs) of the target vehicle and submit it to the activation client so that the user can view the data in the client. In addition, the target vehicle can also be triggered to process the target vehicle status data in response to the processing instructions sent by the activation client for the target vehicle status data. Taking the fault code as an example, if the fault code collected by the activation terminal indicates that the current temperature of the target vehicle is too high, the wiper is faulty and / or the sunroof opening function is abnormal, the user can determine whether the above fault exists: if it does exist, the fault can be removed; if it does not exist (indicating that the fault is a false alarm), the corresponding fault code can be deleted in the electronic device.

[0133] Furthermore, if the activation terminal also includes a data interface module, it can also be connected to a data management device via a physical transmission line, transmitting the collected vehicle status data to a processing device for processing. The processing device can be the aforementioned electronic device, or it can be a dedicated diagnostic tool with extensive vehicle diagnostic capabilities. If the processing device is a dedicated diagnostic tool, the activation terminal of this solution can be used in conjunction with the dedicated diagnostic tool to provide a wider range of maintenance and diagnostic services for the target vehicle, meeting a wider range of user needs.

As shown in Figure 5, this method is applied to an activation client running on an electronic device in an activation system. The activation system also includes an activation terminal, a tire pressure sensor, and a target vehicle. The tire pressure sensor is configured to be installed on a target tire of the target vehicle. The method includes the following steps 502-504.

[0135] Step 502: Instruct the activation terminal to write the target communication parameters of the target vehicle into the tire pressure sensor. The tire pressure sensor after installation is used to submit the status-related data of the target tire to the target vehicle.

[0136] Step 504, instructing the activation terminal connected to the target vehicle via the OBD interface to send the target sensor identifier of the tire pressure sensor to the target vehicle, wherein the status-related data includes the target sensor identifier and the tire status data collected by the tire pressure sensor.
