To notify a user of vehicle theft and its location with a simple system configuration.SOLUTION: A vehicle theft detection system includes: an on-vehicle machine 1 to be mounted on a vehicle 50; a portable unit 2 of a user for communicating with the on-vehicle machine 1; and a server 4 for communicating with the portable unit 2 of the user and a portable unit 3b of a third person. When the vehicle 50 stops at a P-point, the on-vehicle machine 1 acquires first position information indicating a position of the portable unit of the user 2 from the portable unit, so as to periodically transmit the first position information. In a case where the vehicle 50 is thieved and transported from the P-point to a Q-point and when the portable unit 3b of the third person at the Q-point receives the first position information from the on-vehicle machine 1, the portable unit of the third person compares the position itself with the position of the portable unit 2, so as to transmit second position information indicating the position of the portable unit 3b to the server 4 when the positions are separated over a predetermined distance. When the second position information is received, the server 4 transmits the position indicated by the second position information to the portable unit 2 of the user together with warning.SELECTED DRAWING: Figure 4

    【課題】簡単なシステム構成によって車両の盗難および所在地をユーザに報知できるようにする。【解決手段】車両盗難検出システムは、車両50に搭載される車載機1と、この車載機1と通信を行うユーザの携帯機2と、ユーザの携帯機2および第三者の携帯機3bと通信を行うサーバ4とから構成される。車載機1は、P地点で車両50が停止状態になると、ユーザの携帯機2から当該携帯機の位置を示す第1位置情報を取得し、この第1位置情報を周期的に送信する。車両50が盗難されてP地点からQ地点へ運ばれた場合、Q地点にいる第三者の携帯機3bは、車載機1から第1位置情報を受信すると、携帯機2の位置と自身の位置とを比較し、それらの位置が所定距離を越えて離れている場合は、携帯機3bの位置を示す第2位置情報をサーバ4へ送信する。サーバ4は、第2位置情報を受信すると、警報とともに第2位置情報が示す位置をユーザの携帯機2へ送信する。【選択図】図4
