Self-powered sensing module and tire pressure monitoring system using the same
First Claim
1. A tire pressure monitoring system (TPMS) for a vehicle comprising a plurality of tires, the TPMS comprising:
- a self-powered sensing module disposed in each tire to be deformed according to the rotation of the tire, comprising a sensor unit having at least one sensor for measuring at least one of a temperature, a pressure, and acceleration of the tires, a power unit generating a power by deforming mechanically according to the rotation of the tires and supplying the sensor with a power for actuation, and a transmitter unit transmitting data detected by the sensor; and
a main unit disposed in the vehicle and comprising a receiver unit receiving the data transmitted from the transmitter unit and a monitoring unit displaying the received data to a vehicle operator.

Abstract
A tire pressure monitoring system (TPMS) having a self-powered sensing module having a sensor unit with at least one sensor for measuring at least one of a temperature, a pressure, and an acceleration in the tire, and a power unit generating a power by being deformed mechanically according to a rotation of the tire and supplying the sensor with a power required for actuating the sensor. The self-powered sensing module and the TPMS using the same are powered by the power unit generating the power owing to the mechanical deformation, without using a separate power supply. Hence, there is no need to replace a battery of the sensing module and maintenance costs are reduced.
