Method and system for alarming against theft and/or towing of a vehicle that utilizes a TPMS (tire pressure monitoring system)
First Claim
1. A method for alarming against theft and/or towing of a vehicle, comprising;
- detecting internal pressures of tires mounted on the vehicle;
comparing the detected pressures with a predetermined pressure value;
operating a timer if at least one of differences between the detected pressures and the predetermined pressure value is within a scope of a predetermined allowable error; and
generating an alarm message in the case that a state that at least one of the differences between the detected pressures and the predetermined pressure value is within the scope of the predetermined allowable error and is maintained for a predetermined period.

Abstract
A method and system for alarming against theft and/or towing of a vehicle that utilizes a TPMS (Tire Pressure Monitoring System) for detecting internal air pressures of tires in a real time and a vehicle theft. In addition, the theft and/or towing alarms are determined by detecting change (drop) of the air pressures of the tires and the alarm system is turned on by a determination thereof, and simultaneously informed the determination through a wireless terminal of an owner or a manager of the vehicle. Therefore, with preventing of the vehicle theft by an operation of the alarm system, the present invention is for dealing with the vehicle theft and towing by the owner or the manager of the vehicle positively and for improving a confidence to the vehicle.
