Abstract:
A tire monitoring device may be used in conjunction with a tire monitoring system for a vehicle. The tire monitoring device includes a tire monitoring sensor unit having a state monitoring sensor monitoring a tire state, such as a tire pressure, and a first acceleration sensor and a second acceleration sensor respectively measuring accelerations in first and second directions on a plane perpendicular to a wheel axis, and a controller. The controller is configured to determine whether a wheel is on the left or right side of the vehicle on the basis of a relationship between alternating signals of the first acceleration sensor and the second acceleration sensor and determining whether or not a tire event has occurred with reference to a calculated value based on the accelerations measured by the first acceleration sensor and the second acceleration sensor. The tire monitoring device performs minimum operation required for automatic tire location recognition, thereby minimizing battery consumption and reducing the calculation load of the tire monitoring device itself and a central control unit.
Abstract:
Provided is a tire pressure sensor (TPS) of a tire pressure monitoring system (TPMS). The TPS includes a detachable and angle-adjustable tire valve coupled to the front side of a tire pressure sensor housing. A holder bracket having a tire valve insertion hole is at the front side, and an insertion head inserted into the valve insertion hole is at an end of the tire valve. Accordingly, the angle of the tire valve is freely controlled, allowing compatible use regardless of the shape or size of wheels of cars and commercial vehicles. Thus, manufacturing costs can be greatly reduced, thereby obtaining superior competitiveness over competitors' products. Furthermore, air leakage through a wheel valve hole can be effectively prevented against high speed rotation and inertia motion caused by the high speed rotation during the driving of a vehicle.

Abstract:
Provided is a tire pressure sensor valve that can be easily installed to a 2-piece or 3-piece inch-up wheel and protect a tire pressure sensor when removing a tire. The tire pressure sensor valve includes a sensor housing including a mounting space for receiving a PCB to which circuit parts including an air pressure sensor are mounted, and a coupling recess for coupling, a valve body including a head and an inner air inlet hole having an opening-closing member, the head being inserted into the coupling recess of the sensor housing and fixed to the sensor housing through a screw, and a valve adapter including a threaded end such that the end is covered with a valve cap.
