Title:
A METHOD FOR INSTANT MONITORING THE TIRE PRESSURE USING A TIRE PRESSURE MONITORING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2009/094901
Kind Code:
A1
Abstract:
A method for instant monitoring the tire pressure using a tire pressure monitoring system. The tire pressure monitoring system comprises a sensing emitter and a central monitor. An acceleration sensor is disposed in the sensing emitter, which can sense and measure the rotate speed of the wheels to determine the current running state of the vehicle. If the acceleration sensor determines the vehicle is stationary, the system applies a tire pressure DEPT detecting algorithm to monitor the pressure. The tire pressure DEPT detecting algorithm means that, the sensing emitter collects the tire pressure information P once at regular intervals S; thecentral monitor stores the last tire pressure information P0 which is transmitted to the central monitor from the sensing emitter; the current tire pressure information which is actually collected by the sensing emitter is P2, while a tire pressure update fixed value M is set. If |P2-P0|>M, the sensing emitter will transmit P2 to the central monitor which then will store P2 and display it as the current tire pressure value.
