<p>A state judgment unit ( 21 ) of an on-vehicle terminal ( 20 ) judges whether the vehicle is in operation by using outputs of the operation state of a mobile terminal ( 10 ), a key insert switch ( 32 ), an ignition switch ( 33 ), and a courtesy switch ( 34 ). A theft detection unit ( 22 ) includes a diagnosis processing unit ( 22 a) and a monitoring processing unit ( 22 b). When the vehicle is in operation, the diagnosis processing unit ( 22 a) executes diagnosis of a human body sensor ( 41 ), a vibration sensor ( 42 ), and a microphone ( 43 ). When the vehicle is not in operation state, the monitoring processing unit ( 22 b) monitors presence/absence of theft action by using the outputs of the human body sensor ( 41 ), the vibration sensor ( 42 ), and the microphone ( 43 ).</p> |
