The present invention relates to a method for establishing a communicable connection with a tire pressure monitoring system, an apparatus thereof and an electronic device. The method includes: determining several candidate protocol configurations; loading the candidate protocol configurations one by one until at least one usable configuration is determined, the usable configuration being a protocol configuration with which a communicable connection with the tire pressure monitoring system can be established; and establishing a communicable connection with the tire pressure monitoring system based on the usable configuration. By applying the method for establishing a communicable connection with a tire pressure monitoring system, a success rate of a diagnostic device entering a tire pressure monitoring system is improved without increasing hardware device costs. Connection errors do not occur frequently, thereby providing better user experience.

The present invention discloses a tire pressure sensor identification method, a related apparatus and system. A tire pressure sensor identification apparatus in the present invention includes a storage module configured to store identity information of a tire pressure sensor, a communications module configured to communicate with an electronic control unit (ECU) of a vehicle, a processing module and a radio frequency transmission module configured to output identity information. The tire pressure sensor identification apparatus may output the stored identity information to a corresponding vehicle, so that the vehicle can still identify the tire pressure sensor even if the tire pressure sensor is not in an activated state. It is convenient for a user to perform a uniform identification operation after uniformly collecting the identity information, thereby improving identification efficiency of the tire pressure sensor. A tire pressure sensor identification system and a corresponding tire pressure sensor identification method adopting the tire pressure sensor identification apparatus also have a same technical effect.

An electronic wheel unit for detecting a tire pressure of a tire of a vehicle wheel, for storing tire information of the tire and for sending tire pressure information and tire information. The wheel unit is configured to allow the alteration of stored tire information in a first mode of operation and to prevent the alteration of stored tire information in a second mode of operation. To improve the integrity and safety of the stored tire information in this case, the wheel unit is further configured to change from the first mode of operation to the second mode of operation when a first mode change criterion is satisfied. The satisfaction of the first mode change criterion is dependent at least on an operating parameter of the vehicle wheel that is representative of a rotational movement of the vehicle wheel.

The present invention provides a method and an apparatus for activating a tire pressure sensor, a storage medium and a front-end server. The method includes: obtaining a first identification number of the tire pressure sensor; determining a parameter of an activation signal according to the first identification number, the activation signal being used to activate the tire pressure sensor; and sending the activation signal to the tire pressure sensor according to the parameter. According to the method and the apparatus for activating a tire pressure sensor activation provided in the present invention, the first identification number in a one-to-one correspondence with a model of the tire pressure sensor is obtained, the parameter of the activation signal for activating the tire pressure sensor is determined using the first identification number, and the activation signal is sent according to the determined parameter to activate the tire pressure sensor, so that a plurality of automobile-related parameters do not need to be determined in advance during activation of the tire pressure sensor, thereby improving a success rate of activating the tire pressure sensor.

A system for programming a tire pressure sensor includes data processing hardware and memory hardware in communication with the data processing hardware. The memory hardware stores instructions that when executed on the data processing hardware cause the data processing hardware to (i) transmit at least one communication protocol to the tire pressure sensor, and (ii) determine a status of at least one of a power source of the tire pressure sensor or a memory of the tire pressure sensor based on the at least one communication protocol.

A tire pressure monitoring system testing tool includes a housing, an extender that protrudes from one end of the housing, and a signal emitter that disposed in a distal end of the extender. The signal emitter is configured to emit a low frequency radio frequency signal. The testing tool also includes a manually-operated activation switch that is supported on the housing and permits activation of the signal emitter. The extender is configured to provide a relatively large spacing between the switch and the signal emitter so as to permit a standing, upright user to hold the housing in one hand and to place the signal emitter at a ground-height location without requiring the user to bend at the waist or knee. In some embodiments, the length of the extender is in a range of two to twenty times the length of the housing.

The present disclosure relates to a computer-readable storage medium, and a fault detection method and apparatus. The method includes: obtaining first data of tire pressure sensors of a vehicle in a stopping state and a running state; and performing fault detection according to the first data of the tire pressure sensors in the stopping state and/or the running state, and outputting a fault detection result. According to the solutions provided in the present disclosure, a fault type and a fault source can be quickly and accurately positioned, so that maintenance personnel perform fault maintenance quickly and safely, thereby reducing the costs of maintenance and detection, and effectively improving the efficiency and accuracy of fault detection.

Localizing the TPMS sensor module includes measuring a reference phase of the TPMS signal received at the reference reception antenna, measuring a respective shifted phase of the TPMS signal received at each of the at least one additional reception antenna, determining a respective phase shift between the reference phase and each respective shifted phase, and determining a location of the TPMS sensor module based on each determined respective phase shift corresponding to the TPMS signal.

A system for determining a tire change status in a vehicle is provided. The system includes at least one processing device and a storage device. The at least one processing device may be arranged to: calculate a value of at least one reference parameter which may be used in indirect tire pressure monitoring; store the calculated value of said at least one reference parameter in the storage device; retrieve a previously stored value of said at least one reference parameter from the storage device; determine a similarity parameter based on a similarity between the calculated value and the previously stored value of said at least one reference parameter; and determine a tire change status, indicating whether or not the tires have been re-filled or replaced, by comparing said similarity parameter with a threshold.

An apparatus for monitoring a tire pressure includes a controller configured to determine whether vehicle state information and tire information satisfy a reference condition when a reset button of a tire pressure is operated, detect the tire pressure when the vehicle state information and the tire information satisfy the reference condition, and reset the tire pressure when the tire pressure is within a reference pressure range.
