Alternatively, when communication with the registered component is interrupted, the theft determination unit 4 determines that a part of the vehicle has been removed and the theft has occurred by the registered component detection unit 14 as the safety state change determination unit.
The operation after the determination is the same as the first theft determination method.

[Ninth Theft Determination Method]
In the first theft determination method, the lock device 30 is used. However, in the ninth theft determination method, when the authentication by the authentication unit 3 is successful in the base unit 1, for example, in the NAVI unit 38 equipped with GPS. If the position is detected periodically, and the position movement detection unit 15 as the safety state change determination unit detects a position exceeding the moving distance set by the user, the theft determination unit 4 has detected that the theft has occurred. judge. A user who usually uses and sets a region to be used, but can quickly recognize a theft by restricting the region of use to a small amount by the theft determination method changing unit 53 of the handset 50.
The operation after the determination is the same as the first theft determination method.

  When the theft determination unit 4 determines that the theft has occurred, the vehicle display device 29 can display the theft and give a warning to the theft. If the user does not want to inform the theft of the detection of the theft information, the theft determination method changing unit 53 of the handset 50 can prevent the display from being displayed on the display device 29. Can do.

  The vehicle main unit 1 is a vehicle power source, for example, connected to a battery. Normally, the first data center communication unit 22 does not operate when the battery is removed. Will not be able to transmit and will not be able to obtain theft information, and will not be able to track theft. Therefore, since the master unit 1 has a backup power source 23 and the battery is removed, the theft information can be transmitted to the data center 21 so that the theft can be tracked.

  In addition, since the backup power source 23 is always connected, there is a possibility that the backup power source 23 is cut off at the time of theft. Therefore, the backup power source can be charged from the vehicle battery so that the power can be reliably supplied. Since the charging unit 24 is provided, when the theft determination unit 4 makes a theft determination, it functions as the backup power source 23 reliably.

  The master unit 1 can also include an information sharing unit for sharing theft information publicly available to the data center 21 among a plurality of registered users.

  Furthermore, if the backup power supply 23 is easily removed even when the backup power supply is charged, the purpose of theft tracking cannot be achieved. Accordingly, the base unit 1 is mounted on the main part of the vehicle, and the base unit 1 cannot be accessed by the attachment / detachment prevention unit 25 so that the base unit 1 cannot be easily attached / detached unless it is a dedicated tool using a tool that cannot be generally purchased. It has become. Therefore, even if the battery is removed by the theft, it is possible to prevent the tracking of the theft from escaping.

In the first embodiment, a description has been given by taking a motorcycle as an example, but the present invention can also be applied to the theft determination of a relatively small vehicle such as a lawn mower, a snowmobile, or a jet ski. Since the information that can be used for the theft determination differs depending on the vehicle, the same effect can be obtained by determining based on the information input to the vehicle as necessary.
Moreover, although the ninth theft determination from the first theft determination method has been individually described, it is possible to improve the accuracy of the theft determination by combining these theft determination methods as necessary.

Other users who use the system can further prevent theft by giving a prior warning of the theft zone.

  For example, when it is determined that the base unit 1 mounted on the vehicle has stopped by the traveling speed detection unit 10, the first data center communication unit 22 inquires whether the data center 21 has theft information. As a result of this inquiry, if it is determined that there is a stolen vehicle near the stopped zone, the theft zone notification unit 17 issues a warning by, for example, an alarm device 39 that is an alarm buzzer. The user can recognize that the possibility of the theft is high by the alarm, and can enhance the theft prevention by increasing the accuracy of the theft determination by the theft determination method changing unit 53 of the child device 50.

  In addition, in recent years, there are some users who hate to create a database of location information as individual theft information due to privacy protection issues. Therefore, the user can select user information as unspecified theft information rather than individual theft information. The unit 18 can select whether or not to register information in the database. The user selection unit 18 can protect privacy.
