VEHICULAR ANTI-THEFT SYSTEM HAVING GLOBAL POSITIONING SYSTEM RECOGNITION FUNCTION

摘要

PROBLEM TO BE SOLVED: To provide a vehicular anti-theft system having a global positioning system device recognition function.

SOLUTION: This vehicular anti-theft device includes the global positioning system (GPS) and an on-vehicle anti-theft machine. The GPS device, mounted on a vehicle, receives a radio signal and is electrically connected to the on-vehicle anti-theft machine. The on-vehicle anti-theft machine includes a first flag. The first flag includes two types of states of presence and absence of a satellite signal, and commands the presence/absence of the satellite signal. When the on-vehicle anti-theft machine is set to an anti-theft mode and the first flag changes the absence state of the satellite signal to the presence state of the satellite signal, the on-vehicle anti-theft machine transmits a relocation signal.
