Is transmitted to the navigation unit 101, and the navigation operation is performed in the same manner as described above.

  Next, the operation after the driving is stopped, the car is parked in a parking lot at home, for example, and the driver or passenger leaves the car will be described with reference to the flowchart of FIG.

  First, by turning off the engine key, the power of the device body 1 of the car navigation device is turned off (S201), the driver carries the operation unit 2 and gets off, and brings the operation unit 2 into the house such as home. Thereafter, when the user goes out without using a car, the telephone connection part 125 of the operation unit 2 is connected to a telephone line or the like by a modular jack or the like. In this case, the dial destination of the dialer unit 124 is set to the driver's mobile phone number or the like.

  Note that the telephone connection portion 125 of the operation unit 2 can be connected to a telephone line or the like by a modular jack or the like without going out.

  When the power is turned off, the power supply unit 110 is switched to a backup power supply charged during traveling, and the main body control unit 109 detects the power off of the power supply unit 110 and determines the time until the alarm function is activated by the timer unit 107. Counting is started (S202). The time counted by the timer unit 107 is, for example, about 5 to 10 minutes, and is sufficient for the driver or passenger to get off and leave the vehicle during this time.

  When the timer unit 107 finishes counting, the body control unit 109 detects the end of counting and supplies power to the vibration detection unit 106 to start vibration detection operation (S203). The vibration detection unit 106 is parked. The presence or absence of vibration of the apparatus main body 1 is determined (S204).

  If a car is parked and the driver is away from the car, and the thief tries to break the window glass of the parked car or forcibly destroy the car lock, The vibration detection unit 106 detects the vibration of the apparatus main body 1 as theft information (Y in S204). When the vibration detection unit 106 detects vibration, the main body control unit 109 of the apparatus main body 1 sends an alarm signal to the operation unit 2 via the main body communication unit 103 and the antenna 112 by radio waves or infrared rays based on the detection result. Transmit (S205).

  On the operation unit 2 side carried by the driver or placed in the house, the control unit 128 receives the alarm signal transmitted from the apparatus main body 1 via the antenna 129 and the communication unit 121 (S206). .

  In the operation unit 2, an alarm is generated by a sound from the alarm unit 122 in response to the received alarm signal (S 207) to notify the driver, the owner of the car, or the like that there is an abnormality in the parked car.

  In the case of transmission / reception by radio waves, it is also affected by the presence or absence of a shielding object. Or, transmission / reception is possible between the apartment room and the outdoor parking lot of the apartment.

  Now, when the driver or the owner of the car notices an alarm from the operation unit 2, the driver or the like releases the alarm by pressing the alarm release key on the operation unit 120 of the operation unit 2 (Y in S208). After that, the car navigation device theft abnormality is solved by rushing to the parked car.

  Even if an alarm is issued from the operation unit 2, the driver or the owner of the car is away from the operation unit 2 and is not aware of the alarm, or has gone out without using a car and the alarm has not been released ( N) of S208, based on the control by the control unit 128 of the operation unit 2, the dialer unit 124 is driven after a predetermined time has elapsed and connected to the telephone line via the telephone connection unit 125. A call is made with the mobile phone 123 of the owner or the like to inform that there is an abnormality in the parked car.

  The driver who received the call, the owner of the car, and the like solve the theft abnormality of the car navigation device by rushing to the parked car. At that time, an alarm release key (not shown) provided in the apparatus main body 1 is turned on, for example, the power supply to the vibration detection unit 106 is cut off to release the alarm (S209).

By the way, when the vibration detection unit 106 of the apparatus main body 1 does not detect vibration in S204 (N in S204), that is, there is no abnormality in the parked vehicle until the next driving of the vehicle. Therefore, when the door of the car is legally opened by a door key or keyless entry, the door open / close detection unit 113 detects the opening of the door, and the control of the main body control unit 109 of the apparatus main body 1 controls the vibration detection unit 106. The power supply is stopped and the vibration detection operation is stopped (S210).

  Thereafter, by turning on the engine key, the power of the apparatus main body 1 is turned on (S211).

  When the power of the apparatus main body 1 is turned on and an operation is started by the operation unit 2, the authentication unit 108 operates to check whether the operation unit 2 to be operated is compatible with the apparatus main body 1 ( If it is suitable, the navigation unit 2 operates the navigation operation (S213). If it does not match, the navigation unit 2 cannot operate the navigation operation.

  As described above, in the present embodiment, the navigation operation is normally performed, and when the driver leaves the car, the operation unit 2 is removed from the device main body 1 and the driver or the like carries the device to steal the navigation device. When this occurs, an alarm is issued by the operation unit 2 that is carried, and the countermeasures against theft can be immediately taken.

  Moreover, since the act of breaking the window of the parked car, forcibly destroying the car lock, or illegally unlocking the car is the same as the case of stealing the car, the device body 1 of the car navigation device is stolen. Prevention also serves to prevent car theft.

  Furthermore, if the telephone connection part 125 of the operation unit 2 is connected to the telephone line, the driver does not respond even if an alarm is issued, or the vehicle is not used while the operation unit is left in the house. When the user goes out, he / she can be notified automatically to the driver's mobile phone, for example, to tell the theft.

  If the operation unit 2 is stolen when it is left in the car, the operation unit 2 in front of the thief will issue an alarm at the same time as the window glass of the car is destroyed. Even if it is stolen when it is not known that the device main body 1 that has been operated does not operate, an alarm is issued to the operation unit 2 that is close to it, and in any case, a high anti-theft effect can be obtained. .

  The vibration detection by the vibration detection unit 106 in the above embodiment may be performed at all times while the car is parked, but in order to reduce power consumption, for example, it may be performed intermittently every few seconds. May be.

  Further, the alarm in the alarm unit 122 in the above embodiment may be a sound as in the present embodiment, or may be performed by various methods such as light and vibration.

  In the above embodiment, the timer unit 107 counts the time so that vibration detection is started after a predetermined time has elapsed since the driver turned off the engine key and the apparatus main body 1 was turned off. In addition to this, it is also possible to count the predetermined time after detecting the closing of the door of the car or the turning off of the room light, and the extent to which the driver has completely left the car after getting off It is sufficient to set so as to count the time.

  Also, in the above embodiment, if there is no response from the driver even if an alarm is issued, the driver's mobile phone is reported, but this is not a mobile phone, but this is a home fixed phone or driver You may make it call the telephone of the place where there is a family.

  In particular, when the user is indoors and is away from the operation unit 2, a telephone set in a place where a driver or a family is present may be called.

  When a call is made to a mobile phone, a fixed phone, or the like, even if there is no message just by making a call, the party may know that it is an emergency situation. It is possible to add a message or notify the nearest police station, but it is highly functional and expensive.

  Furthermore, although the case where the in-vehicle device is a car navigation device has been described in the present embodiment, it goes without saying that the present invention is applied to various in-vehicle devices such as a television and a DVD.

  Furthermore, in the above embodiment, the alarm unit 122 is provided only in the operation unit 2, but even if alarm means other than the alarm unit 122 is provided in the apparatus main body 1, an alarm is issued even before the thief as described above. The effect of the present invention is further enhanced.
