A triple-band trigger tool for a tire-pressure monitoring system is disclosed. The tool body includes a 315 MHz transceiver circuit and a 315 MHz antenna electrically connected to each other, and the 315 MHz transceiver circuit is electrically connected to a control unit; the tool body also includes a 433 MHz transceiver circuit and a 433 MHz antenna electrically connected to each other, and the 433 MHz transceiver circuit is electrically connected to the control unit; the tool body also includes a Bluetooth transceiver circuit and a Bluetooth antenna electrically connected to each other, and the Bluetooth transceiver circuit is electrically connected to the control unit. Therefore, the triple-band trigger is able to perform a firmware programming operation on a TPMS sensor at 315 MHz, 434 MHz or Bluetooth frequency band.

A valve with elastic deformation and having a tubular core adapted to form an internal air passage from an external longitudinal end of the valve to an internal longitudinal end, the tubular core being at least partially surrounded by a sleeve of elastically deformable material and having a bulb shape widening in proximity to the internal longitudinal end of the valve and ending in an internal longitudinal bulb end. A cup made of rigid material includes a first portion facing an internal longitudinal bulb end face and at least one second portion curved away from the internal longitudinal end of the valve, the cup serving as a way of limiting deformation of the bulb.

A tire pressure monitoring system used for a vehicle includes a sensor unit, a receiving device, and a control device. The sensor unit is provided at each wheel of the vehicle, detects tire pressure of the each wheel with a tire pressure sensor and transmits data of the detected tire pressure by radio waves. The receiving device includes a receiving antenna that is provided at an outside of the vehicle to receive the data of the tire pressure transmitted from the sensor unit. The control device includes a data acquisition unit that acquires the data of the tire pressure received by the receiving device.

The present invention provides a fixing device for installing a pressure-type airbag sensor. The fixing device for installing a pressure-type airbag sensor includes a holder having a disk shape, a cover coupled to the holder and having a sensor unit disposed at an upper end thereof, and a connector housing disposed at a lower end of the cover. The cover may include a cover body having a disc shape. Reverse rotation prevention protrusions protruding outward may be formed at intervals at a plurality of positions on an outer circumference of the cover body. Rotation guide protrusions may protrude from the plurality of positions of the cover body, and corners thereof may be formed in a predetermined curvature. The rotation guide protrusions may be formed to correspond to the number of rotation locking parts formed on an outer wall of the holder.

This application relates to a tire monitoring system. In one aspect, the system includes a sensor module installed in a tire provided in a vehicle to obtain tire data and a communication module. The communication module may include a transceiver configured to transmit and receive the tire data, and an output unit configured to output one of a caution signal and a warning signal. The communication module may also include a controller configured to determine whether a state of the tire is abnormal based on the tire data and control the output unit to output one of the caution signal and the warning signal based on the determination result.
