-199155). That is,
When theft of a vehicle is detected based on the output of a door switch, a glass break sensor, or the like, the current location information obtained by the navigation system for the vehicle is automatically dialed and transmitted to a predetermined telephone by the vehicle-mounted telephone and transmitted. That is. Therefore, the receiving side can take an appropriate measure such as immediately reporting to the police. It has also been proposed to redial while the other party is busy.

[0003]

However, even if an attempt is made to transmit the current location information of the vehicle to the owner of the vehicle by using the vehicle-mounted telephone, such transmission is not possible if the vehicle-mounted telephone is used by a criminal. Can not. In addition, if the criminal knows that the vehicle-mounted telephone is being used to report the current location information of the vehicle, such a report will be prevented halfway, and if the owner is absent, the vehicle theft report will be delayed, When the system is operated by a criminal, there is a problem that transmission of the current location information is hindered.

[0004]

Therefore, according to the present invention, when a vehicle is stolen, information about the stolen vehicle can be promptly transmitted by making it impossible to use the vehicle-mounted telephone for telephone calls. Is to ensure that a predetermined person can be notified.

That is, the invention of this application is based on a theft detection means for detecting theft of a vehicle based on a predetermined illegal operation performed on the vehicle, and a current location provided on the vehicle and outputting information on the current location of the vehicle. Information output means, and an on-vehicle telephone, wherein when the vehicle theft detection means detects theft of the vehicle, the current location information of the vehicle obtained by the current location information output means is transmitted to a predetermined location using the on-vehicle telephone. In the vehicle antitheft device configured to transmit the information to a person, when the vehicle theft is detected, the mode is changed to a current location information output-only mode in which the in-vehicle telephone cannot be used for a telephone call.

Therefore, even if a person who has stolen the vehicle tries to talk with the outside using the vehicle's vehicle-mounted telephone, the vehicle-mounted telephone and the external telephone are not connected, and the output of the current location information of the vehicle is hindered. I can't.

In the present invention, the transmission of the current location information is performed by
In addition to transmitting information as voice, it includes facsimile transmission of information as characters or graphics.

In the above vehicle antitheft device, when a theft of the vehicle is detected and a telephone number of the other party is inputted to use the vehicle telephone, a telephone line connection signal is not output from the vehicle telephone. Preferably, after the other party's telephone number is input, a notification that the other party's phone is busy is issued from the vehicle-mounted phone, and the number of the other party's phone is stored.

In other words, even if a person who has stolen the vehicle attempts to use the vehicle-mounted telephone, it only informs that the other party's telephone is busy, so it is sensed that the vehicle-mounted telephone is in the current location information output-only mode. Hateful. In addition, by outputting the stored telephone number of the other party separately, it becomes a clue for searching for a person who has stolen the vehicle.

When the receiver of the car phone is picked up,
Alternatively, when the operation switch of the vehicle-mounted telephone is turned on, a signal sound of a predetermined wavelength (sound "two") or the like indicating that communication is possible is output. When a telephone is about to be used, it is preferable to emit such a signal tone or the like. The above-mentioned notification during talking may be a signal sound, a sound, or a lamp display.

In the case where the other party's telephone number is stored as described above, it is preferable that this telephone number be output together with the current location information of the vehicle and transmitted, whereby the speed of the stolen person of the vehicle can be increased. It is advantageous for a search.

When the vehicle-mounted telephone is changed to the current position information output-only mode as described above, the transmission of the current position information of the vehicle is tried every predetermined time, and the output from the external telephone is made at the time of non-transmission or non-trial. Wait for command,
It is preferable that when there is an output command, the current location information is transmitted based on the command.

That is, in this case, since the current location information of the vehicle is transmitted intermittently to a predetermined person, the telephone of the predetermined person is not exclusively used for reception, and the predetermined person cannot receive the telephone. It becomes easy to report the theft of the vehicle to the police using a telephone, and by issuing an information output command to the vehicle-mounted telephone, necessary current location information can be appropriately obtained.

As the above-mentioned information output command, the transmission destination of the current location information of the vehicle is separately designated, and the transmission of the current location information to the designated transmission destination, for example, the nearest police station ahead in the traveling direction of the vehicle. Doing so is advantageous for searching for stolen vehicles.

Further, when the vehicle-mounted telephone is changed to the current position information output-only mode as described above, the transmission of the current position information of the vehicle may be attempted to a plurality of persons in a predetermined order. It is suitable.

That is, if the transmission is made to only one specific person, the report of the theft of the vehicle will be delayed when that person is absent. This will reduce the delay in reporting. In this case, for example, the transmission may be attempted in the order of the mobile phone of the owner of the vehicle, the phone of the person's house, a predetermined police station, and the like.

Further, when the vehicle-mounted telephone is changed to the current position information output only mode as described above, the vehicle is provided with an in-vehicle speaker, and when the current position information of the vehicle is transmitted, the transmission is performed. If the in-vehicle speaker informs the stolen person of the vehicle by using the in-vehicle speaker, it is effective in giving up the person to keep stealing the vehicle or in prompting his own head.

Further, when the vehicle-mounted telephone is changed to the current location information output-only mode as described above, a power supply circuit capable of manually turning on / off the connection to a power source for the current location information output means and the vehicle-mounted telephone is provided. It is preferable that a power circuit dedicated to the theft to connect the current position information output means and the vehicle-mounted telephone to a power supply when the vehicle is stolen is detected besides the power circuit.

That is, even if the person who stolen the vehicle notices the transmission of the current position information by the current position information output means and the vehicle-mounted telephone and temporarily turns off the power, a dedicated power supply circuit is provided. Will not be disturbed.

Further, when the vehicle-mounted telephone is changed to the current position information output-only mode as described above, two methods of transmitting the current position information using the vehicle-mounted telephone are provided: voice transmission and facsimile transmission, and the vehicle speed detection means is provided. If the vehicle is traveling, voice transmission is performed, and if the vehicle is parked, facsimile transmission including graphic information represented by a map of the current location of the vehicle is performed. This is an advantage in assuring reliable communication.

Further, when the vehicle-mounted telephone is changed to the current location information output-only mode as described above,
When a vehicle enters a forked road from a traveling road previously transmitted as current position information, accurate information can be transmitted to a predetermined person by further transmitting current position information of the vehicle.

Further, when the vehicle-mounted telephone is changed to the current position information output only mode as described above, if the vehicle has a display for displaying the output of the current position information output means, the display interface is set to the off mode. By doing so, it is possible to prevent a person who has stolen the vehicle from detecting the operation of the current location information output means,
This is advantageous in avoiding manipulation of the means.

Further, when the vehicle-mounted telephone is changed to the current position information output-only mode as described above, the information on the nearest police station ahead of the vehicle in the traveling direction is transmitted together with the current position information of the vehicle. The predetermined person who has received the transmission is convenient in reporting the theft to the nearest police station, and the report can promptly prevent the vehicle from being stolen.

[0024]

Therefore, according to the invention of this application, when a vehicle is stolen, use of the on-board telephone by a burglar is prohibited, and the current location information of the stolen vehicle is given to a predetermined person by the on-board telephone. The notification can be made promptly, which is advantageous for searching for the stolen vehicle or the stolen person.

After the owner of the vehicle has left the vehicle, the control unit 1 determines whether the door of the vehicle is locked or stolen based on the output of the various sensors 2. A self-diagnosis of the condition of the vehicle is carried out, and when there is an abnormality based on the result of the diagnosis, the vehicle-mounted telephone 5 informs a registered person such as the owner of the vehicle in advance, and based on a command from the owner, The processing necessary for eliminating the abnormality is performed.

The sensor 2 for self-diagnosis of the vehicle includes an engine rotation sensor for detecting operation of the engine, a sensor for detecting insertion of an ignition key or a door key, a sensor for detecting opening and closing of a door, and a sensor for detecting door lock. , A sensor for detecting opening and closing of a window glass, a sensor for detecting breakage of a window glass, a sensor for detecting lighting of a lighting system, a vehicle speed sensor, and the like.

The navigation device 3 detects the position of the vehicle using GPS measurement and dead reckoning navigation using a vibration gyro, a vehicle speed sensor, and the like, and compares the detected position with the map data in the CD-ROM. To determine the position,
The display 4 displays characters of the current position and graphic display of the position on the map. The vehicle-mounted telephone 5 is used to transmit information about the current location of the vehicle when the vehicle is detected to be stolen by the control unit 1 when the vehicle is stolen, and has a facsimile function. ing. Dedicated power supply 7
Is operated when a vehicle theft is detected, and enables the use of the navigation device 3 and the vehicle-mounted telephone 5 even when the power is turned off by the operation switch 6.

The travel control device 10 includes an engine output control means and a brake control means used for an anti-skid brake device and a traction device.

<Self Diagnosis of Vehicle State> Diagnosis of the vehicle state based on the various sensors will be described with reference to the flow chart shown in FIG.

First, when the engine is operating without a key, the vehicle is stolen and the "theft mode" is set (steps S1 to S3).
If the door is not locked, the lock “Forget Mode” is set.If the window is opened beyond a certain opening, the window close “Forget Mode” is set, and the lighting system lights up unnecessarily. If any of them are turned off, the "Forget mode" is set.If the door is locked with the key inserted, the "Forget mode" without the key is set and the door is locked with the key inserted. If not, the key "forget mode" is set (steps S4 to S1).
3). In addition, when the current location of the vehicle changes, the theft mode is set, and when the theft prevention is activated, the theft mode is set (steps S14 and S15). The anti-theft operation is when the door is unlocked without a key or the window glass is broken, and an alarm is issued.

<Status Information Reporting Process> When each of the above modes is set, the vehicle-mounted telephone 5 is turned on to try to connect to the telephone of the vehicle owner or the like. Is notified (transmitted) of the content of the error, and if connection is not possible, it is redialed at predetermined time intervals. In the case of the "forgotten mode", the forgotten items are transmitted by voice or text. The recipient may, if necessary,
A door lock command or the like is given to the control unit 1 through the vehicle-mounted telephone 5. When the “stolen mode” is set, the following processing is performed.

-Notification processing in the theft mode-If a predetermined notification has not been made yet (F = 0), first secure power supply by a dedicated circuit, turn off the navigation screen, NAVI line mode for the vehicle-mounted telephone 5 Setting, storage of the theft time, and tracking of the current location of the vehicle by the navigation device 3 are performed (step S2).
1, S22).

The power supply is secured by connecting a dedicated power supply circuit bypassing the operation switch 6 to the navigation device 3 and the vehicle telephone 5 by the dedicated power supply device 7. As a result, even if the stolen user turns off the operation switch 6, the navigation device 3 and the vehicle-mounted telephone 5 operate based on the command of the control unit 1. The navigation screen is turned off by turning off the display interface.
Thus, the stolen person cannot detect the operation of the navigation device 3.

The setting of the NAVI line mode for the vehicle-mounted telephone 5 prohibits the vehicle-mounted telephone 5 from talking with an external telephone and makes the vehicle-mounted telephone 5 dedicated to the output of the current location information by the navigation device 3. In such a case, the other party's telephone number input to the vehicle-mounted telephone 5 is stored while presuming that the vehicle-mounted telephone 5 can be used by a stolen person.

That is, when the operation switch of the telephone 5 is turned on (or when the receiver is picked up) so that the vehicle-mounted telephone 5 can be used, a signal of a predetermined wavelength indicating that communication is possible from the receiver is performed. It emits a sound (sound "two"). When the telephone number of the other party is input by the push button (dial) of the vehicle-mounted telephone 5, the telephone signal is prevented from being output from the vehicle-mounted telephone 5, thereby preventing the connection / call with the other party's telephone. After the input of the other party's telephone number, a signal tone indicating that the other party's phone is busy (an intermittent signal tone of a predetermined wavelength “two, two,...”) Is output from the vehicle-mounted phone 5. The number of the other party's telephone is stored for later output.

Subsequently, predetermined items such as the fact that the vehicle has been stolen are reported from the vehicle-mounted telephone 5 to a predetermined person registered in advance. That is, in the case of the present embodiment, the telephone numbers of the two persons are given a priority, for example, the mobile phone of the owner of the vehicle is set as the first place, and the telephone of the owner's house or a predetermined police The telephone of the office is registered as the second place. Therefore, first, a call is made to the first priority telephone, and if the line cannot be connected, a call is made to the second priority telephone. If the connection cannot be made, the telephone is redialed in the same order after a predetermined time (step). S23 to S27). Further, the control unit 1 is configured to receive an output command of the current location information from the owner of the vehicle via the on-vehicle telephone 5 (step S28). The information output command will be described later.

When the telephone is connected to a predetermined person or when an information output command is issued, predetermined information is transmitted from the vehicle-mounted telephone 5 by a voice signal (step S29).
The information to be reported includes, for example, the fact that the vehicle has been stolen, the current position of the vehicle, the traveling direction and the average vehicle speed, the number of offenders, and the location of the nearest police station ahead in the traveling direction. The message of the theft occurrence is registered in the control unit 1 in advance, and the current position, the traveling direction, and the nearest police station of the vehicle are obtained by the navigation device 3 and converted into audio signals, and the average vehicle speed is the vehicle speed. Obtained by the sensor, the number of offenders is estimated based on the number of times the door of the vehicle is opened and closed.

After the notification, the transmission by the vehicle-mounted telephone 5 is turned off and a flag is set (F = 1), and the fact of the notification flows from the in-vehicle speaker 9 into the vehicle through a message registered in advance ( Steps S30 to S3
2). When a predetermined time (5 minutes) has elapsed after the notification, the notification process is performed again (step S2).
1 → S33 → S23). The reason for waiting for the elapse of the predetermined time is to allow the owner of the vehicle to report a stolen fact to the police station by his / her telephone during that time.

If the navigation device 3 detects that the vehicle has deviated from the previously reported traveling direction due to the vehicle turning a forked road before the predetermined time has elapsed, the vehicle with respect to the vehicle at that time is detected. The information is reported again (steps SS33 → S34 → S23). When an information output command is issued from the owner of the vehicle, a notification is made based on the command (step S3).
5 → S29).

When the vehicle has been parked for a predetermined time, a report of the theft is sent to a predetermined place by facsimile transmission (steps S36 and S3).
7). The predetermined place in this case is the home of the owner of the vehicle, a police station, or the like. The contents of the facsimile transmission include, for example, the vehicle theft facts shown in FIG. 4, the characteristics of the stolen vehicle, items related to the owner, the presence or absence of the culprit, the character information of the other party's telephone number, etc. FIG. 6 is graphic information (map information) on a traveling route to a parking place, and is an image diagram (three-dimensional view) of the parking place of the vehicle shown in FIG. 5. The characteristics of the stolen vehicle and matters relating to the owner are registered in advance, the presence or absence of a culprit is estimated from the opening and closing of the door, and the graphic information is obtained by the navigation device 3.

When the theft mode is released, the flag is set to F = 0, and the state information reporting process is terminated (steps S38 and S39).

-Information output command- When the owner of the vehicle gives an information output command to the control unit 1 by telephone, the vehicle telephone 5 is called, and a predetermined signal is transmitted using "#" and a numeric keypad. This is performed by inputting to the control unit 1 via the vehicle-mounted telephone 5. When the vehicle-mounted telephone 5 is in the theft mode (information output only mode), a bell sound indicating an incoming call is not sounded. The types of information output commands are, for example, as follows.

# 1: Voice output of stolen information # 11: Facsimile output of stolen information # 12: Input of destination of stolen information # 1333; Vehicle stop command # 1444; In-vehicle speaker ON

The above is for instructing the output of the information in step 29 of FIG. The above commands the output of the information of FIGS. The above specifies a location other than a pre-registered location (for example, the nearest police station ahead of the vehicle in the traveling direction) as the transmission destination of the theft information. Of the stolen information by voice or facsimile. The above is for instructing the control unit 1 to operate the traveling control device 10 and preventing the stolen vehicle from escaping by reducing the engine output or the like.
