Received acceleration or motion information are analyzed and when the analysis of this information indicates that motion or acceleration is detected, received burst patterns from the other sensors are analyzed. Based upon analyzing the detected burst patterns from the other sensors, a first burst pattern is selectively altered to transmit according to a single communication format, the single format being for a single vehicle manufacturer.

The present invention provides a tire pressure sensor identification method, apparatus and device. The method includes: sending an activation signal to a to-be-detected tire pressure sensor, till receiving a feedback signal sent for the activation signal by the to-be-detected tire pressure sensor, where the feedback signal includes feature information of the to-be-detected tire pressure sensor; and identifying the to-be-detected tire pressure sensor according to the feature information. The present invention implements automatic scanning of the tire pressure sensor and can accurately identify the tire pressure sensor according to a scanning result, thereby improving activation efficiency of the tire pressure sensor.

A method, device and apparatus for dynamically monitoring the working state of a vehicle, and a storage medium are disclosed. The method includes: waking up a monitoring unit according to a vehicle starting signal, acquiring the load of the vehicle, the tire pressure of a wheel and the temperature of a wheel hub through the monitoring unit, and determining the working state of the vehicle according to the load of the vehicle, the tire pressure of the wheel and the temperature of the wheel hub.

A tool device for use with a motor vehicle tire pressure monitoring system (TPMS) operable to send and receive signals to a TPMS tire pressure sensor and a radio frequency identification (RFID) tag positioned in a vehicle tire. In one example, the tool is operable to communicate with the RFID tag to receive information from the RFID tag through an ultra-high frequency communication module and send that received RFID tag information to the tire pressure sensor for storage on the tire pressure sensor. The tool may then retrieve the tire pressure sensor information and associated RFID tag information from the sensor and transmit that information to the motor vehicle on-board computer.

Sensor assemblies and systems comprise a housing configured to accommodate an electrical sensor device therein, mechanically retain the same, and provide a protective surrounding thereto. The housing may include display indicia relating to some aspect of the sensor assembly. The electrical sensor device include electrical components useful for the purpose of monitoring and transmitting desired data relating to operating parameters/conditions of the dynamic article that the sensor assembly is attached with, e.g., a vehicle tire. The data is transmitted wirelessly from the electrical sensor device. The housing is removably attached with a retaining member that is also attached with the dynamic article. A receiver external from the dynamic article receives the data for the purpose of determine such operating parameter/or conditions, when the dynamic article is a vehicle tire, as tire tread depth, tire pressure, vehicle camber and toe alignment variations, and tire/vehicle location, which may be stored.

A system includes a computer having a processor and a memory storing instructions executable by the processor to acquire a first image of a tire of a vehicle upon shutdown of the vehicle. The instructions include instruction to then, upon startup of the vehicle, and in response to determining that the tire is unmoved since the shutdown and, in response, acquire a second image of the tire. The instructions include instruction to actuate a component of the vehicle in response to determining that the first image is different that the second image.

According to one embodiment, a method of improved communication between a wheel unit sensor and a master controller is disclosed. In this particular embodiment, the method includes determining, by the wheel unit sensor, whether a receive schedule of the wheel unit sensor indicates that a receive window has started. The method also includes in response to determining that the receive schedule indicates that the receive window has started, turning-on, by the wheel unit sensor, for the duration of the receive window, a wireless receiver of the wheel unit sensor. In this embodiment, the wireless receiver is configured to receive messages from the master controller.

A portable tire pressure monitoring system (TPMS) tool includes a tire sensor trigger device ensuring the TPMS tool is in close proximity to a TPMS tire sensor to trigger or awaken the sensor to emit measured tire data. In one example, a manually displaceable trigger signal contact device in the form of a push button is used. On manual displacement of the push button against the tire, the tool generates the tire sensor trigger signal. In another example, the tool includes a first power source in the form of a high density capacitor. In another example, a second power source in the form of a lithium button-type battery is used to selectively provide power or recharge the first power source between function cycles.
