[0037] definition

[0038] “Innerliner” means the layer or layers of elastomeric or other material that form the inner surface of a tubeless tire and contain the inflating gas within the tire.

[0039] “TPMS” stands for Tire Pressure Monitoring System, which is an electronic system that measures the pressure inside a tire and transmits that pressure to a processor mounted on the vehicle and / or in electronic communication with the vehicle's electronic system. DETAILED DESCRIPTION

[0040] The present disclosure relates to programming tire sensors according to various embodiments. A tire sensor may be programmed with tire identification data, which may be unique to the tire to which the tire sensor is attached. However, if the tire sensor fails during the useful life of the tire, the sensor may need to be replaced. Traditionally, tire sensors are externally programmed with unique tire identification data and / or other relevant data prior to being placed into service. External programming of replacement sensors is an inherently manual, error-prone process that may raise data integrity and security issues. Therefore, it would be beneficial to be able to automatically program sensors with tire identification data and / or other relevant data.

[0041] In various examples, an identification tag device (e.g., a radio frequency identification (RFID) tag) stores tire information data and / or other data specific to a given tire. In various examples, the identification tag device may be attached to or otherwise contained within a tire-integrated sensor mount configured to support a sensor. In various examples, the identification tag device is configured to transmit tire identification data and / or other data stored by the identification tag device to the sensor when the sensor is attached to or otherwise supported by the tire-integrated sensor mount. Thus, the sensor may obtain tire identification data associated with the tire on which the sensor is mounted, thereby allowing the sensor to associate the collected sensor data (e.g., pressure, temperature, etc.) with tire identification data specific to the tire. It should be noted that although the discussion of the present disclosure relates to pneumatic tires, the present disclosure is not limited to pneumatic tires and may be applied to all types of tires, including pneumatic tires and non-pneumatic tires.

[0042] refer to Figure 1, the vehicle 100 is shown having one or more tires 103 (e.g., 103a, 103b, 103c, 103d, 103e). Although shown and described as pneumatic tires, it should be noted that the tires 103 are not limited to pneumatic tires and can be applicable to all types of tires, including pneumatic tires and non-pneumatic tires. Each tire 103 includes a sensor 106 (e.g., 106a, 106b, 106c, 106d, 106e). In various examples, the sensor 106 is mounted on each tire 103 to detect certain real-time parameters of the tire 103, such as tire pressure and tire temperature. In various examples, the sensor 106 may include at least one of the following: a pressure sensor for sensing the inflation pressure in the tire cavity; a temperature sensor for measuring the temperature of the tire; an accelerometer for measuring the acceleration of the wheel on which the tire 103 is mounted; a tachometer for measuring the rotation time of the wheel; and / or other types of sensors.

[0043] In some embodiments, sensor 106 is a component of or includes a tire pressure monitoring system (TPMS) module or sensing unit. In some aspects, each tire 103 on vehicle 100 includes one or more sensors 106. Although vehicle 100 is depicted as a commercial truck, vehicle 100 may include any type of vehicle that uses tires, with commercial trucks being presented as an example. To this end, vehicle 100 may include other vehicles belonging to various categories, such as passenger cars, off-road vehicles, etc., where these vehicles include, for example, Figure 1 A greater or lesser number of tires 103 than those shown may be used.

[0044] Now turn to Figure 2 and Figure 3 , shows a cross-sectional view of a tire 103 with the sensor mounting assembly mounted inside the tire 103. In particular, Figure 2 A cross-sectional view of tire 103 on wheel 203 is shown with sensor mounting assembly 206 mounted inside tire 103 . Figure 3 A cross-sectional view of the tire 103 without the wheel 203 is shown, with the sensor mounting assembly 206 mounted inside the tire 103. The tires 103 are of conventional construction, and each tire is mounted on a corresponding wheel 203, as known to those skilled in the art. Each tire 103 includes a pair of sidewalls 209 (e.g., 209a, 209b) extending to a circumferential tread 212. An airtight layer 215 is disposed on the inner surface of the tire 103, and when the tire is mounted on the wheel 203, an internal cavity 218 is formed, which is filled with a pressurized medium, such as air.

[0045] In various examples, the sensor mounting assembly 206 includes a sensor holder 221, a tire identification (ID) tag 224, and a sensor 106. In some examples, the sensor 106 can be removably attached from the sensor holder 221. For example, if the sensor 106 fails during its useful life (e.g., the useful life of the tire 103), the sensor 106 may need to be replaced. Thus, the sensor 106 can be disassembled or otherwise removed from the sensor holder 221 to allow placement of a replacement sensor 106. Thus, in some examples, the sensor mounting assembly 206 can include the sensor holder 221 and the tire ID tag 224 without the sensor 106.

[0046] like Figure 2 As shown, the sensor mounting assembly 206 includes a tire ID tag 224 that is fixed to the sensor support 221 or otherwise integrated or contained within the sensor support 221. In various examples, the sensor 106 can be attached or mounted on the sensor support 221 so that the sensor 106 engages or abuts the inner surface of the sensor support 221. In some examples, the sensor 106 is mechanically mounted to the sensor support 221. In other examples, the sensor 106 is attached to the sensor support 221 by an adhesive or other suitable attachment form. It should be noted that the positioning of the tire ID tag 224 and the sensor 106 within the sensor mounting assembly 206 allows the sensor 106 to communicate with the tire ID tag 224 according to embodiments of the present disclosure.

[0047] The sensor support 221 is designed and configured to support the sensor 106, which detects certain real-time parameters of the tire 103, such as tire pressure and tire temperature. It should be noted that the size and shape of the sensor support 221 are not limited to Figure 2 The sensor holder 221 may be of any suitable size and shape such that the sensor 106 may be attached to and supported by the sensor holder 221. In various examples, the sensor holder 221 is attached to or integrated within the airtight layer 215 and / or other components of the tire 103. For example, the sensor holder 221 may be attached to the tire 103 by an adhesive or other suitable type of attachment device. In other examples, the sensor holder 221 is integrated within one or more components of the tire 109. In some examples, the sensor holder 221 may be molded into one or more components of the tire 109 during the manufacturing process of the tire 109. In some examples, the sensor holder 221 may be formed of a material similar to and / or the same as the material of the airtight layer 215 and / or other tire components. In other examples, the sensor holder may be formed of plastic and / or other suitable types of materials, as long as the sensor holder 221 can support the sensor 106 during operation of the tire 103.

[0048] In various examples, the tire ID tag 224 comprises a conventional radio frequency identification (RFID) tag device. In some examples, the tire ID tag 224 is a dipole configuration, although other tag configurations may be used if desired. The tire ID tag 224 is of a general type, including a substrate supporting an IC (integrated circuit) package and having a conductive coil antenna arm. Such a tag is shown and described in U.S. Patent No. 8,441,355, which is hereby incorporated by reference in its entirety.

[0049] In various examples, the tire ID tag 224 can store tire information that is specific to the tire 103 on which the tire ID tag 224 is installed. The tire information can include a tire identifier (ID), manufacturing information for the tire 103 (e.g., model, manufacturer name, etc.), size information (e.g., rim size, width, and outer diameter), manufacturing location, manufacturing date, crown code including or associated with compound identification, mold code including or associated with tread structure identification, and / or other information. The vehicle tire information can also include a maintenance history or other information to identify specific features and parameters of each tire 103. In various examples, the tire ID tag 224 is operable to wirelessly transmit tire identification data to the sensor 106 and / or other remote receiver.

[0050] In various examples, the sensor 106 is mounted on the tire 103 for the purpose of detecting certain real-time parameters (e.g., tire pressure and tire temperature) of the tire 103. In various examples, the sensor 106 may include at least one of the following sensors: a pressure sensor for sensing the inflation pressure in the tire cavity; a temperature sensor for measuring the temperature of the tire; an accelerometer for measuring the acceleration of the wheel on which the tire 103 is mounted; a tachometer for measuring the rotation time of the wheel; and / or other types of sensors.

[0051] In various examples, the sensor 106 includes a processor and a memory for storing vehicle tire information for each specific tire 103. For example, the vehicle tire information may include a tire identifier (ID), manufacturing information for the tire 103 (e.g., model, manufacturer name, etc.), size information (e.g., rim size, width, and outer diameter), manufacturing location, manufacturing date, a crown code including or associated with a compound identification, a mold code including or associated with a tread structure identification, and / or other information. The vehicle tire information may also include a maintenance history or other information to identify specific features and parameters of each tire 103. In various examples, the sensor 106 is configured to wirelessly communicate with the tire ID tag 224 to receive tire identification data from the tire ID tag 224.

[0052] Sensor 106 also includes an antenna for wirelessly transmitting measured parameters and tire information data to a remote processor for analysis, such as a processor integrated into a vehicle computing device, a controller area network (CAN) bus associated with vehicle 100, and / or a cloud computing device. According to various embodiments, each tire 103 on vehicle 100 may include one or more of sensors 106.

[0053] Now go to Figure 4 , shows a networked environment 400 according to various embodiments. The networked environment 400 includes the sensor 106 and the tire ID tag 224, which communicate data with each other through a network 403.

[0054] In various examples, network 309 may include a local area network (LAN) and may include wired or wireless components or a combination thereof. A wireless network may include an Institute of Electrical and Electronics Engineers (IEEE) 802.11 wireless network (i.e., ), Networks 403 may also include a combination of two or more networks 403.

[0055] In various examples, the tire ID tag 224 includes a conventional radio frequency identification (RFID) tag device. For example, the tire ID tag 224 can include a memory 406, a communication circuit 409 (e.g., a transmitter, a receiver, a transceiver, etc.), a power module 410, and a coupling element 412 (e.g., an antenna or a coil).

[0056] The memory 406 may include tire ID data 415, sensor data 418, and / or other data. The tire ID data 415 may include a tire identifier (ID), manufacturing information for the tire 103 (e.g., model, manufacturer name, etc.), size information (e.g., rim size, width, and outer diameter), manufacturing location, manufacturing date, crown code including or associated with compound identification, mold code including or associated with tread structure identification, and / or other information. The vehicle tire information may also include a maintenance history or other information to identify specific features and parameters of each tire 103.

[0057] Sensor data 418 may include information collected by sensor 106. For example, sensor 106 may collect real-time parameters of tire 103, such as tire pressure, tire temperature, acceleration, rotational speed, and / or other parameters related to the tire. In various examples, sensor 106 may include at least one of: a pressure sensor for sensing the inflation pressure within the tire cavity; a temperature sensor for measuring the temperature of the tire; an accelerometer for measuring the acceleration of the wheel on which tire 103 is mounted; a tachometer for measuring the rotation time of the wheel; and / or other types of sensors.

[0058] In various examples, the sensor data 418 may include data that has been collected by a sensor 106 that is no longer in communication with the tire ID tag 224. For example, if a sensor 106 fails during the useful life of a given tire 103, the sensor 106 may be replaced with a replacement sensor 106. In some examples, the sensor data 418 stored in the tire ID tag 224 may correspond to events or collected data associated with the previous sensor 106 before the failure thereof, and may be transmitted to the replacement sensor 106 or other remote receiver, as may be appreciated.

[0059] In the example of an RFID tag, the memory 406 and the communication circuit 409 can be implemented on an RFID chip. In various examples, a portion of the tire ID tag 224 (e.g., an RFID chip) that includes the communication circuit 409 and / or the memory 406 can be in contact with the coupling element 412, or it can have an on-chip coil that can be inductively coupled to another coil, to one or more antennas, or to the coupling element 412 that are tuned to the operating RF frequency or possible RF frequencies of the sensor 106. For example, the coupling element 412 can be tuned to the operating frequency of the sensor 106, for example, to one of the Industrial, Scientific, and Medical bands (ISM), such as 315 MHz, 434 MHz, etc.

[0060] In various examples, the communication interface of the communication circuit 409 includes an I2C or SPI that is commercially available for use in conjunction with and with an integrated circuit (IC). As used herein, "I2C" or "SPI" refers to an integrated circuit (I2C) developed by Philips (now NXP) Semiconductors of Eindhoven, the Netherlands, or a serial peripheral interface (SPI) developed by Motorola of Schaumburg, Illinois, respectively. In various examples, the communication circuit 409 of the tire ID tag 224 is coupled to a power module 410, which is further coupled to a tag coupling element 412 of the tire ID tag 224. The power module 410 is configured to receive energy from the sensor 106 through the sensor coupling element 421 to power the tire ID tag 224. That is, the tire ID tag 224 includes a contact with the coupling element 412, or it may include an on-chip coil inductively coupled to the coupling element 412.

[0061] In various examples, sensor 106 is configured to detect certain real-time parameters of tire 103, such as tire pressure and tire temperature. In various examples, sensor 106 may include at least one of the following sensors: a pressure sensor for sensing the inflation pressure within the tire cavity; a temperature sensor for measuring the temperature of the tire; an accelerometer for measuring the acceleration of the wheel on which tire 103 is mounted; a tachometer for measuring the rotation time of the wheel; and / or other types of sensors.

[0062] In various examples, the sensor 106 includes a processor, a sensor communication circuit 424, a memory 428, a sensor coupling element 421, and / or other components. The sensor communication circuit 424 may include a transmitter, a receiver, a transceiver, and / or other types of communication components that allow the sensor to communicate with the tire ID tag 224 and / or other devices. For example, the sensor communication circuit 424 may include an antenna for wirelessly transmitting measured parameters and tire information data to a remote processor for analysis, such as a processor integrated into a vehicle computing device, a controller area network (CAN) bus associated with the vehicle 100, and / or a cloud computing device. The sensor memory 428 stores tire ID data 415, sensor data 418, and / or other data specific to a given tire 103.

[0063] The sensor coupling element 421 (e.g., an antenna, a coil, etc.) is configured to provide power (e.g., RF power) to the tire ID tag 224 so that the tire ID data 415 can be provided. For example, the sensor 106 may include a dedicated output to provide power to the tire ID tag 224, wherein the sensor coupling element 421 may also be dedicated or used for multiple purposes, including providing power to the tire ID tag 224. In some examples, the communication circuit 424 of the sensor 106 may be coupled to the sensor coupling element 421 (e.g., the same or another antenna or coil), and it is configured to transmit information related to the tire pressure to a receiver device of the vehicle 100, the tire ID tag 224, and / or other devices.

[0064] Go to Figure 5 , shows an example sequence diagram 500, which provides an example of the operation of the various components of the network environment 400. It should be understood that Figure 5 The sequence diagram 500 provides only one example of many different types of functional arrangements that may be used to implement the operation of the depicted portion of the network environment 400. Figure 5 The sequence diagram 500 may be viewed as an example of depicting elements of a method implemented within the network environment 400. In particular, Figure 5 The sequence diagram 500 depicts functions associated with establishing and exchanging information between the sensor 106 and the tire identification tag 224. For example, the tire identification tag 224 includes tire ID data 415 stored in the memory 406. When the sensor 106 (e.g., original or replacement) is attached to the tire integrated support 221 of the tire 103, the sensor 106 can power the tire identification tag 224 contained within or coupled to the tire integrated support 221 and receive tire ID data 415, sensor data 418, and / or other data stored on the tire ID tag 224 from the tire ID tag 224.

[0065] Beginning at block 503, the sensor 106 provides power to the tire ID tag 224. For example, when the sensor 106 is supported by the tire integrated support 221 of the tire, the sensor coupling element 421 (e.g., antenna, coil, etc.) of the sensor 106 provides power (e.g., RF power) to the tire ID tag 224 so as to be able to provide the tire ID data 415. For example, the sensor 106 may include a dedicated output to provide power to the tire ID tag 224, wherein the sensor coupling element 421 may also be dedicated or used for multiple purposes, including providing power to the tire ID tag 224.

[0066] At block 506, the tire ID tag 224 detects communication with the sensor 106. For example, when the sensor 106 is placed in operational proximity to the tire ID tag 224, the coupling element 412 of the tire ID tag 224 may be coupled to the sensor coupling element 421. Thus, the tag coupling element 412 may receive energy (e.g., power) from the sensor coupling element 421. In this way, the power module 410 of the tire ID tag 224 coupled to the sensor coupling element 421 may power the tire ID tag 224 using the energy received from the sensor coupling element 421, thereby detecting the sensor 106.

[0067] At block 509, the tire ID tag 224 transmits the tire ID data 415, the sensor data 418, and / or other data stored in the tag memory 406 to the sensor memory 428. In various examples, the communication circuit 409 of the tire ID tag 224 is configured to transmit the data in the tag memory 406 to the communication circuit 424 of the sensor 106.

[0068] At block 512, the sensor 106 stores the received data in the sensor memory 428. In various examples, when the sensor 106 collects parameter data related to the tire and transmits the parameter data to the remote device, the sensor 106 can associate the collected data using the tire ID data 415 obtained from the tire ID tag 224. Thereafter, this portion of the process continues until completion.
