BACKGROUND OF THE INVENTION
The present invention relates to a theft monitoring system.
[0002]
[Prior art]
In recent years, on-vehicle electronic devices such as navigation devices and audio devices have been frequently stolen from parked cars. As a countermeasure against theft of such an in-vehicle electronic device, for example, a navigation device provided with a security function is known (see, for example, Patent Document 1). In this navigation device, the security mode (warning mode) can be set by inputting an ID code or the like that can be freely determined by the owner. After the security mode is set, if the connection between the navigation device and the in-vehicle battery is interrupted due to the removal of the navigation device, etc., the navigation device determines this as theft and restricts the operation after the theft. Yes. When the navigation apparatus is turned on, a message indicating that the security function is provided is displayed on the display. This gives a feeling of psychological oppression to unauthorized users and prevents theft.
[0003]
In recent years, not only in-vehicle electronic devices but also the vehicle itself may be stolen. As a vehicle theft countermeasure, for example, it is known to install a mobile terminal device that includes a position detection unit that detects the current position of a vehicle based on a signal from a GPS satellite, a wireless communication unit, and the like. (For example, refer to Patent Document 2). The owner can confirm the vehicle position via the mobile terminal device, and can monitor abnormalities such as theft of the vehicle. Even when an abnormality occurs, the vehicle can be tracked by detecting the current position of the vehicle.

[Problems to be solved by the invention]
However, in the conventional mobile terminal device (Patent Document 2), the security mode can be canceled without inputting an ID code or the like, so that the security mode is easily canceled by an unauthorized user. Further, if the mobile terminal device is broken or thrown out of the vehicle, the vehicle cannot be tracked. For this reason, the mobile terminal device must be installed in an inconspicuous place in the vehicle. However, if it is installed in an inconspicuous place in the vehicle, operations such as setting and releasing the security mode are cumbersome, making it inconvenient. In addition, if the owner forgets the presence of the mobile terminal device and drives without releasing the security mode, the mobile terminal device may judge this as theft and report it to a security company or the like. there were. On the other hand, since the conventional navigation device (Patent Document 1) uses an ID code for setting or canceling the security mode, it is difficult for an unauthorized user to cancel the security mode. Further, since the navigation device is installed in a place that can be seen well from the driver's seat, it is possible to notify an unauthorized user that the anti-theft function is installed. Therefore, a certain effect can be expected in terms of suppressing theft of the navigation device. However, there is a possibility that an unauthorized user may destroy a navigation device that performs an annoying display, and an unauthorized user who intends to steal a vehicle does not have an anti-theft effect.

[0017]
The input display unit 24 includes a display unit 24a and a touch panel 24b superimposed on the display screen.
The display unit 24a is configured by an LCD (Liquid Crystal Display) or the like, and displays a personal identification number input screen as shown in FIG. 2 based on various control signals input from the control unit 21 or the theft monitoring device 3. A warning message (see FIG. 4) and a navigation transition screen (see FIG. 3) are displayed according to the verification result based on the password verification process. In addition to the display information for navigation (map information, route information, etc.), the password verification process will be described later.
[0018]
The touch panel 24b is formed in a transparent film shape, and functions as an input unit for inputting a password. The position information touched on the touch panel 24b by the owner is detected by the coordinate reading principle such as the resistive film type, the ultrasonic type, the optical type, the electrostatic capacitance type, the infrared scanning type, the retroreflective type, etc. An input signal is output to the control unit 21.
[0019]
For example, when the password input screen shown in FIG. 2 is displayed on the display unit 24a, when the owner touches the number input key 51 on the touch panel 24b and touches the OK button 53 after the completion, the touched number input key is displayed. An input signal corresponding to 51 is output to the control unit 21.

[0023]
The autonomous navigation unit 26b includes an angular velocity sensor (gyro), a distance sensor, and the like. The angular velocity sensor detects the angular velocity of the vehicle (the rotation angle in the horizontal direction per unit time) and calculates the amount of change in the moving direction. A distance sensor detects the pulse signal output according to rotation of a wheel, and calculates the moving amount | distance of a vehicle. The autonomous navigation unit calculates a relative position change of the vehicle based on these angular velocity signal and vehicle speed pulse signal, and outputs it to the control unit 21.
[0024]
The power detection unit 27 detects whether or not the power of the navigation device 1 is turned on, and outputs a detection signal to the control unit 21. Note that turning on and off the power of the navigation device 2 is interlocked with the switching of the ignition switch of the vehicle. That is, when the ignition switch is set from the initial position to a predetermined position (ACC position), power supply from the ACC power supply system to the navigation device 2 is started. When the control unit 21 detects that power supply to the navigation device 2 is started by the power supply detection unit 27, the control unit 21 starts the security mode release process.
[0025]
The I / F unit 28 is an interface for inputting and outputting various signals between the navigation device 2 and the theft monitoring device 3.
[0026]
Next, the theft monitoring device 3 will be described.
The theft monitoring device 3 performs a theft monitoring operation as described in the above-described outline description, and is installed in a place where it cannot be seen such as in a trunk or under a seat. When set to perform the theft monitoring operation, the theft monitoring device 3 detects theft detection processing for detecting unauthorized movement of the vehicle, removal of the vehicle-mounted device, etc., and if the theft is detected, the owner's home or mobile phone, Theft notification processing for notifying a predetermined contact information such as a security company is performed.
[0027]
Further, when the security code is input together with the theft monitoring operation release command signal from the navigation device 2, the theft monitoring device 3 performs a security code verification process for verifying a match between both security codes in advance by comparing the security code with the security code. If the two match, the theft monitoring operation is stopped.
[0028]
Next, the configuration of the theft monitoring device 3 will be described.
As shown in FIG. 1, the theft monitoring device 3 exchanges various signals with the control unit 31, the storage unit 32, the vibration detection unit 33, the position detection unit 34, the communication control unit 35, and the navigation device 2.

Specifically, various control programs stored in the storage unit 32 are read, and various processes such as a password verification process and a theft notification process are executed in cooperation with the control program.
[0030]
In the personal identification number verification process, when the personal identification number is input together with the theft monitoring operation release command signal from the navigation device 2, the control unit 31 and the personal identification number stored in the personal identification number storage area 32 a of the storage unit 32. Match. Then, it verifies the coincidence of both password numbers, and transmits the verification result information to the navigation device 2. Further, when the two passwords match, the control unit 21 stops the vibration detection operation of the vibration detection unit 33 and cancels the security mode.
[0031]
In the theft notification process, the control unit 31 detects the current position from the position detection unit 34 and acquires the position information when the correct password is not input within a predetermined time. Then, the communication control unit 35 controls to notify a predetermined contact (for example, the owner's home, mobile phone, security company, etc.) via the wireless communication line together with the acquired position information. .
[0032]
The storage unit 32 is composed of a ROM or the like, and has a personal identification number storage area 32a in which a personal identification number is stored in advance. The personal identification number is distributed from the security company or the like, for example, by a contract with the security company, and is used for authenticating the owner. In addition, the storage unit 32 stores various programs necessary for the control unit 31 to execute the above processes.
[0033]
The vibration detection unit 33 monitors the unauthorized movement of the vehicle and theft of the in-vehicle electronic device by detecting the vibration of the vehicle. Such a vibration detection unit 33 can be constituted by, for example, a vibration detection sensor in which a conductive ball contact made of a metal sphere is accommodated between two plate-like terminals. In the vibration detection sensor configured as described above, the conductive ball contacts come into contact with both terminals when stationary, and the terminals are turned on.When the vibration is detected, the conductive ball contacts roll in the housing and move away from the terminals for a moment. Chattering occurs. By using this, vibration is detected, and a detection signal indicating no vibration is output to the control unit 31 when chattering is occurring when the terminal is ON. .
[0034]
The position detector 34 includes a GPS antenna 34a, receives a GPS signal transmitted from a GPS satellite via the GPS antenna 34a, and detects the current position of the theft monitoring device 3 based on the received GPS signal. The position information is output to the control unit 31.
[0035]
The communication control unit 35 includes an antenna 35a, establishes a wireless communication line with the wireless base station, and transmits and receives wireless signals. Thereby, based on the control signal input from the control unit 31, a theft occurrence signal and vehicle position information are notified to a predetermined contact via the base station.
[0036]
The I / F unit 36 is an interface for inputting and outputting various signals between the theft monitoring device 3 and the navigation device 2.
[0037]
The power supply unit 38 is configured by a chargeable / dischargeable secondary battery or the like, and supplies predetermined drive power to each unit of the theft monitoring device 3. The power supply unit 38 is charged by receiving power from a car battery.
[0038]
Next, the operation of the theft monitoring system 1 will be described with reference to FIG.
FIG. 5 is a flowchart showing security mode release processing executed by the control unit 21. When the power is turned on, the control unit 21 starts the security mode release process based on the detection signal output from the power supply detection unit 27.
[0039]
First, the control unit 21 determines whether or not the theft monitoring device 3 is set to the security mode (step S1). When it is determined that the theft monitoring device 3 is set to the security mode (step S1: Y), the control unit 21 displays a personal identification number input screen together with a message indicating that the theft monitoring operation is being performed on the display unit 24a. (See FIG. 2) is displayed (step S2).
[0040]
Next, the control unit 21 monitors whether or not a password is input within a time limit (for example, 3 minutes) (step S3). When the password is input within the time limit by the owner (step S3: Y), the control unit 21 transmits the password that is input together with the theft monitoring operation release command signal to the theft monitoring device 3 (step S4). If the security code is not entered within the time limit (step S3: N), a warning screen that displays a message such as “Please enter the security code” is displayed, and functions other than the warning screen display are stopped (step S3). S9). Further, the theft monitoring device 3 executes a theft notification process in step S9 to notify the occurrence of the theft to a predetermined contact such as the owner's home or a security company.
[0041]
In step S4, when a password is transmitted from the navigation device 2, the control unit 31 of the theft monitoring device 3 performs a password verification process. Then, the personal identification number stored in the personal identification number storage area 32a is verified by collating the input personal identification number. If both personal identification numbers match, the security mode is canceled and the security mode is canceled. A signal indicating this is returned to the control unit 21. Further, as a result of the verification, if the two passwords do not match, the theft monitoring device 3 does not return a signal indicating that the security mode has been released to the control unit 21.
[0042]
The control unit 21 determines whether or not the security mode has been canceled based on the signal indicating the verification result information returned from the theft monitoring device 3 (step S6). If it is determined that the security mode has been canceled by receiving a signal indicating that the security mode has been canceled, the process proceeds to step S7, the navigation mode transition screen shown in FIG. 3 is displayed, and the security mode cancellation process is terminated.
[0043]
On the other hand, when it is determined in step S6 that a signal indicating that the security mode has been released cannot be received and the security mode has not been released (step S6: N), that is, the password entered via the touch panel 24b is If there is an error, the control unit 21 determines whether the number of times that the wrong password has been input has reached a predetermined number (for example, 5 times) or the security mode within a predetermined time after displaying the password input screen. It is determined whether or not a signal indicating that has been released is received (step S8).
[0044]
If it is determined in step S8 that the predetermined number of times has not been reached or the predetermined time has not elapsed (step S8: N), the control unit 21 displays a caution screen on the display unit 24a (step S5), and the password is input again. A screen is displayed (step S2). At this time, an alarm or the like may be output from the audio output unit 25.
[0045]
If it is determined in step S8 that the predetermined number of times has been reached or a predetermined time has elapsed (step S8: Y), the control unit 21 displays a warning screen on the display unit 24a and the navigation device 2 displays the warning screen. Functions other than the display of are stopped (step S9). In step S9, the theft monitoring device 3 executes a theft notification process and notifies the occurrence of the theft to a predetermined contact such as the owner's home or a security company.
[0046]
As described above, according to the present embodiment, the security mode can be canceled from the navigation device 2 even if the theft monitoring device 3 is installed in a place where it cannot be easily removed such as in the trunk or under the seat. So it is easy to operate and easy to use. In the present embodiment, when the navigation device 2 is turned on, the security mode release processing is performed. Therefore, the owner forgets to release the security mode and travels, and the theft monitoring device 3 reports the theft. There is nothing. Furthermore, since the owner is authenticated by the password, an unauthorized user cannot cancel the security mode.
[0047]
In addition, since it is displayed on the display unit 24a of the navigation device 2 that a theft monitoring operation is being performed, such as a password input screen, a caution screen, and a warning screen, an unauthorized user who is attempting to steal the vehicle It can give a feeling of psychological pressure. Thereby, the anti-theft effect can be obtained.
[0048]
Furthermore, when the same password as the password stored in the theft monitoring device 3 is not input from the navigation device 2 within a predetermined time, the control unit 21 stops the functions other than the display of the warning screen of the navigation device 2. Unauthorized use of the navigation device 2 can be prevented. Furthermore, even if an unauthorized user thinks that the navigation device 2 has a theft monitoring function and destroys the navigation device 2 in order to stop the theft monitoring operation, the unauthorized user actually performs the theft monitoring operation. Since it is the theft monitoring device 3 installed under the trunk or under the seat, the theft notification processing or the like can be performed.
[0049]
Further, if a password that matches the password stored in the theft monitoring device 3 is not input, or if a password is not input within the time limit, the theft monitoring device 3 notifies the theft when a predetermined time has elapsed. Since the processing is performed, the owner, the security company, etc. can receive the theft notification and rush to the scene quickly. Moreover, since the current position of the vehicle can be detected by the position detection unit 34 of the theft monitoring device 3, the vehicle can be tracked.
[0050]
In addition, this invention is not limited to the said embodiment, Of course, it can change suitably in the range which does not deviate from the main point of this invention.
For example, in the above-described embodiment, the navigation apparatus 2 is described as an example of the vehicle-mounted electronic device. However, the vehicle-mounted electronic device of the present invention is not limited to this, and may be a car audio device, a television receiver, or the like. There may be. In the above embodiment, the touch panel 24b is described as an example of the input unit. However, the input unit is not limited to this. In the vicinity of the display unit 24a, there may be an operation panel provided with various keys associated with various functions such as use of navigation in addition to character keys, numeric keys, and search keys, or an input device such as a remote controller. Also good.
[0051]
【The invention's effect】
