A method includes operating a transceiver of a tire pressure monitoring system in an active operation mode, where the transceiver includes a battery and a data storage device. The method includes determining whether the transceiver is coupled to an external power source, and determining whether the data storage device of the transceiver includes sensor identifier data stored thereon when the transceiver is not coupled to the external power source. The method further includes transitioning the transceiver from the active operation mode to a battery storage mode when the data storage device does not include sensor identifier data stored thereon and the transceiver is not coupled to the external power source.

The present application provides a programming method and a programming device based on tire pressure sensing, which is related to the technical field of pressure sensing. The programming method includes: transmitting a region identification including at least one of a country, a region and a customer to an intelligent terminal through near-field communication for requesting the intelligent terminal to automatically match a database with the region identification and return a manufacturer code corresponding to a preset vehicle model identification from the database; receiving the manufacturer code sent by the intelligent terminal through near-field communication; and programming the tire pressure sensing device based on the manufacturer code. The programming method avoids an operator frequently manually switching countries, regions and customers on the intelligent terminal to match with the database, and also avoids a situation that the tire pressure sensing device cannot work normally due to error of manual switching.

A method of configuring a tire monitoring device including, at the tire monitoring device: entering a configuration mode; responsive to entering the configuration mode, transmitting a first message to a second device, the message indicating that the second device should transmit configuration data to the tire monitoring device; receiving configuration data from the second device in response to the first message; and configuring the tire monitoring device based on the configuration data.

Method and apparatus are disclosed for controlling a TPMS sensor of a vehicle tire. An example vehicle includes a communication module, a tire, and a TPMS sensor corresponding to the tire. The TPMS sensor is configured to receive a target pressure from the communication module, determine a modified target pressure based on vehicle data determined by a vehicle sensor, and, responsive to determining that a measured pressure differs from the modified target pressure by a threshold amount, transmit an alert to the communication module.

A data transmission control method and apparatus, and a terminal are disclosed. The method includes: performing, by a master terminal, a timing negotiation with respective slave terminals to obtain timings allocated to the respective slave terminals; sending, upon completion of timing allocation, interactive data by means of broadcasting, the interactive data being sent to the slave terminals; receiving responses of the respective slave terminals to the received interactive data according to the allocated corresponding timings; and acknowledging, using the received responses, completion of transmission of the interactive data to the slave terminals. The data transmission control method and apparatus and the terminal can be used to improve data transmission efficiency and channel utilization.

A near-field communication-based tire pressure monitoring system, a sensor, a tire, and a vehicle. The tire pressure monitoring system comprises a server (101), a terminal (102) supporting near-field communication, and a tire pressure monitoring sensor (103) supporting near-field communication. The terminal (102) obtains from the server (101) update information for updating the tire pressure monitoring sensor (103), and then the update information is transmitted to the tire pressure monitoring sensor (103) by establishing a near-field communication connection between the terminal (102) and the server (101), so that the tire pressure monitoring sensor (103) realizes information reconfiguration or programming process. The terminal (102) is connected to the tire pressure monitoring sensor (103) by means of near-field communication, and compared with wireless communication, the near-field communication avoids the interference of irrelevant signals, guaranteeing the normal communication process. Since the interference of irrelevant signals is avoided, hang-up prevention is encrypted in the near-field communication process without additionally increasing a processing packet, and the cost is reduced.

A transmitter is coupled to each of a plurality of wheel assemblies included in a vehicle. The transmitter is configured to function in one of a plurality of formats that are selectable by a command from a trigger device. The transmitter includes a pressure sensor configured to detect the tire pressure, a memory that stores an ID code, a transmission unit configured to transmit a signal, a controller configured to control the transmitter, and a trigger reception unit configured to receive a trigger signal including the command from the trigger device. The controller is configured so that when the trigger reception unit receives a trigger signal including a command designating a format of the transmitter, the controller has the transmitter function in the designated format and has the transmission unit transmit the signal including the ID code to register the ID code to an in-vehicle receiver.

An electronic wheel unit for a wheel-monitoring system of a vehicle is disposed on one of the wheels and is configured to detect at least one wheel operating parameter of the wheel and to transmit wheel operating data telegrams according to a data transmission protocol wirelessly to a control device, configured to receive and evaluate the wheel operating data telegrams. The electronic control unit defines the data transmission protocol, which is to be used to transmit the wheel operating data telegrams, by using specification data which have previously been transmitted from the control device to the electronic wheel unit. Therefore, automatic adaptation of the data transmission protocol to the respective control device or the respective vehicle can advantageously take place. A control device for such a wheel monitoring system and a system and a method for monitoring wheels are also provided.

A method of determining an orientation of a tire mounted device with respect to a wheel rim using an acceleration sensor, With the wheel in a designated orientation and not rotating, a polarity of acceleration along a vertical axis is determined. Then it is determined which of a first absolute orientation or a second absolute orientation the tire mounted device is in depending on the determined polarity. The determined absolute orientation is correlated with the designated orientation to determine which of a first or second orientation with respect to the wheel rim the tire mounted device is in.

A method for the configuration of a tire pressure sensor for a vehicle, including the following steps: production of a data communication connection between a mobile radio device and a tire pressure sensor, selection of at least one specific sensor parameter for the vehicle via a mobile radio device, and activation of the at least one selected sensor parameter and the tire pressure sensor.
