<p><P>PROBLEM TO BE SOLVED: To provide a vehicle theft tracing system, a vehicle theft monitoring device, and a vehicle theft tracing method capable of securing a high security against vehicle theft. <P>SOLUTION: Each vehicle 2 is furnished with an alarm function device 5 and a radio communication device 10. The alarm function device 5 judges whether a deed for vehicle theft is being conducted on the basis of the sensing signals given by a group 8 of sensors, and if yes in judgement, the device 5 emits an alarm through a horn 9 and transmits a theft notification signal Sa. The radio communication 10 can exchange radio LAN communications with the alarm function device 5, and when receiving the theft notification signal Sa from the device 5, transmits a theft notification signal Sb in response to Sa. Even if the burglar has removed the alarm function device 5, the radio communication device 10 left in the vehicle 2 puts the vehicle 2 in the condition that the signal Sb is transmitted from the vehicle 2. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
