Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial application field) The present invention relates to a device for automatically transmitting information for prompt recovery of a vehicle when the vehicle is stolen, The present invention relates to a vehicle information transmitting apparatus for automatically photographing and transmitting a scene inside or outside a vehicle when the vehicle is stolen.

(Prior Art) Conventionally, in order to prevent a vehicle from being stolen, firstly, door locks, power windows and the like have been improved in order to prevent a stealer from entering a vehicle. Recently, an anti-theft device that emits an alarm sound on a vehicle or wirelessly issues an alarm when a door or window is opened or an abnormal vibration of a window is detected without input of a code has been proposed. 2. Even if the person who wants to steal enters the vehicle, if the appropriate key (key) is not attached to the engine key switch unit (key cylinder) and the key is rotated, or a predetermined code is electrically connected. If you do not send or input, you can not start the engine,
In addition, mechanisms or electric lock systems have been proposed that also lock the handle so that the handle does not rotate.

(Problems to be solved by the invention) However, there are cases where a vehicle is invaded by destroying a door lock or a window.
Also, destroying the engine key switch unit,
Alternatively, the vehicle may be stolen due to the direct connection of the ignition system power supply line to the battery among the electric wires drawn into the unit. Since the ignition system power supply line is connected to vehicle elements related to vehicle traveling, when the ignition system power supply line is connected to the battery, the vehicle can be driven in the same manner as when the owner is operating. it can. Once a thief starts driving the vehicle, locating the vehicle and the criminal is:
It is very difficult, and searching and retrieving stolen vehicles requires a great deal of effort, which can be wasted.

An object of the present invention is to facilitate identification of a criminal and / or location of a vehicle when the vehicle is stolen.

[Configuration of the invention]

(Means for Solving the Problems) In order to achieve the above object, a vehicle information transmitting apparatus according to the present invention comprises: first detecting means for detecting rotation of a wheel; and electrically connecting an ignition system power line to a battery on the vehicle. Second detecting means for detecting connection; third detecting means for detecting whether or not the electrical connection is a regular connection set in advance in the vehicle; generating an image signal by photographing at least one of the inside and the outside of the vehicle. Imaging means; transmission means for wirelessly transmitting an image signal; and when the first detection means detects rotation of the wheel while the second detection means detects an electrical connection and the third detection means detects no. Image signal transmission control means for transmitting the image signal by energizing the imaging means and the transmission means.

(Operation) When connecting the ignition system power supply line to the on-vehicle battery, for example, if an owner driver is described as an example, an engine key (key) is inserted into a vehicle engine key switch unit (key cylinder) and turned. Perform an operation. Alternatively, a card is inserted into a predetermined slot, or an encryption code is input to the vehicle using a code transmitter. That is, the owner driver operates some kind of hardware on the vehicle, or inputs a code to an input board, a card reader, or a wireless receiver on the vehicle.

The third detecting means detects the presence or absence of such an operation or input. Therefore, in the case of normal operation, the second detecting means electrically connects the ignition system power line to the battery on the vehicle,
In other words, when ignition on is detected,
The third detecting means has already detected the operation or the input “present”.

However, when the second detecting means detects the ignition on, the third detecting means detects "absence" (abnormal ignition on; connect the ignition system power supply line to the battery without performing the above operation or input. If there is an abnormality in the connection means for turning on / off the line and the on-vehicle battery and an abnormality in the third detection means), and the first detection means detects the rotation of the wheel,
An image signal transmission control unit energizes the imaging unit and the transmission unit to transmit an image signal. As a result, at least one of the video information inside and outside the vehicle is wirelessly transmitted. On the receiving side, the video information can thus be displayed on a CRT display and / or printed out and recorded on a video recorder as required.

Therefore, when the thief connects the ignition power supply line to the on-vehicle battery and rotates the wheels (towing even when the vehicle is driven by the power of the engine or when the engine is stopped) without performing the operation or input to be performed by the owner driver, the video information Is automatically transmitted, and a thief image is sent to the receiving side in a mode in which the inside of the vehicle is imaged by the imaging means, and a scene outside the vehicle (near the road) in the mode in which the outside of the vehicle is imaged. This facilitates the identification of a thief or the location of a vehicle.

Other objects and features of the present invention will become apparent from the following description of embodiments with reference to the drawings.

Force control device
13 includes an eye mode (low level L) instruction line for detecting the eye mode (detecting the driver's eyes, detecting its position and opening / closing pattern, and turning on / off an on-vehicle accessory electric device corresponding to the detection). the front monitoring instruction (low level L) line in front monitoring device 12 provides a signal (low level L) to instruct them from the output port a ₀ of the microprocessor 2, and, energization control apparatus for an electric device 13 From
The switching gate 16 receives image data obtained by binarizing the video signal captured by the camera 21 and image data obtained by binarizing the video signal captured by the camera 12 from the forward monitoring device 12. I have.

The rotor ROR of the engine key switch unit (key cylinder) KSU is connected to the on-vehicle battery BAT. The key cylinder KSU is a key detection contact KD for detecting the mounting of a key (key held by the driver), an accessory contact AC for connecting a power supply circuit equipped with accessories such as a radio to the battery BAT, an engine ignition circuit and other vehicle driving. It has an ignition contact IG for connecting a power supply circuit of an associated electric device or electric circuit to the battery BAT, and a starter contact ST for connecting a starter motor to the battery BAT.

When the key held by the driver is not mounted on the key cylinder KSU, the rotor ROR is pushed back up by the return spring, and the rotor ROR connected to the battery BAT has the key detection contact KD, the accessory contact AC, and the ignition contact IG.
And none of the starter contacts ST.

When the key is inserted into the key cylinder KSU to the rotatable position, the rotor ROR is depressed and contacts the key detection contact KD, the battery voltage appears on the electric line connected to the key detection contact KD, and the output of the constant voltage circuit 37k Edk switches from low level L to high level H. When the key is rotated to the accessory position, the rotor ROR contacts the contact KD while keeping contact with the contact KD, the battery voltage appears on the electric line connected to the contact AC, and the output Eda of the constant voltage circuit 37a changes from L to H. Switch. When the key is rotated to the engine operating position, the rotor ROR contacts the ignition contact IG while contacting the contacts KD and AC, a battery voltage appears on the ignition system power line Igp connected to the contact IG, and the constant voltage circuit 37g The output Edg switches from L to H. When the key is turned to the engine start position, the rotor ROR is set to the contact KD
And IG, while away from the accessory contact AC, contacts the contact ST, and the starter is connected to the battery BAT. When the engine starts, the rotor ROR is returned to the engine operating position.

Therefore, when the engine is running, the rotor
By ROR, the key detection contact KD, accessory contact AC and ignition contact IG are connected to the battery BAT,
The outputs Edg, Edk and Eda of the constant voltage circuits 37g, 37k and 37a are all H. The above is the key cylinder KSU properly
This is the state when operated by a key possessed by an appropriate driver.

When the ignition system power supply line Igp is connected to the battery BAT due to the destruction of the key cylinder KSU or the short-circuit connection of the key cylinder retraction electric line, the contact KD and / or the contact AC are not connected to the battery BAT, and the output Edg of the constant voltage circuit 37g is Is high, there is a high probability that the output Edk and / or Eda of the constant voltage circuit 37k and / or the constant voltage circuit 37a will be low.

The wheel rotation sensor 5 generates one finger speed electric pulse per rotation of the wheel 4 at a predetermined small angle, and a wheel speed detection circuit 6
Performs an F / V conversion of the finger speed pulse, generates an analog voltage indicating the wheel rotation speed Vs (peripheral speed: vehicle speed), and supplies the analog voltage to the A / D conversion input port ADc of the microprocessor 2.

In this embodiment, as described later, Edg is H (the power supply line Igp is at the battery voltage level), at least one of Edk and Eda is L (not the battery voltage), and the wheels are rotating (wheel rotation). When speed Vs ≧ set value Vr), it is regarded as a first abnormality (theft, etc.), and Edg is set to L (power supply line Igp
Is not the battery voltage level) and the wheel is rotating (Vs ≧ Vr), it is regarded as a second abnormality (theft, etc.),
Or, in the case of the second abnormality, the microprocessor 2 activates the relay driver 9 to close the relay 10, and the forward monitoring device 12, the activation control device 13, the lamp controller 14, the irradiation angle controller 15, Turn on the power of the facsimile FAX and the mobile phone radio WSR (connect the ignition system power line Igp to the battery BAT),
The image of the driver's seat (the face of the person sitting in) and the image in front of the vehicle taken at 19 are transmitted by radio waves.

A battery voltage is applied to a power supply circuit 1 that supplies power to the microprocessor 2 via a power switch PSW. Therefore, as long as the power switch PSW is closed, the operating voltage is applied to the microprocessor 2 even if no key is mounted on the key cylinder KSU. In addition,
When the power switch PSW is closed, the power-on reset circuit 3 generates a reset pulse, and the microprocessor 2 performs an operation reset (starts control operation from initialization) in response thereto.

The vehicle is equipped with a facsimile FAX. The serial data transmission and reception ports Ss and Sr of the controller (microprocessor) 17 are connected to the serial data reception and transmission ports Sr and Ss of the microprocessor 2. I have.

In this embodiment, the facsimile facsimile includes an image receiving mode for receiving an image of a document of another station via a normal telephone line (voice communication line), an image transmitting mode for transmitting an image of a document on a car to another station, and an on-vehicle mode. In addition to a copy mode for duplicating an original image and a text receiving mode for receiving text (character code) data on the transmitting side via a data communication line and reproducing the text, , An external image writing mode, an external image reproducing mode, and a memory image transmitting mode.

In the image receiving mode, the facsimile fax is received by the mobile phone radio WSR, and the line controller 26 and the modem 25 are received.
(Telephone number) sent to controller 17 via
Is the own station, the controller 17 instructs the modem 25 to transmit a reception protocol, establishes a connection with the other party, and under the control of the controller 17, transmits the communication signal received by the wireless device WSR to the modem 25. At 25, the compressed data is restored to compressed image data (compressed data) and stored in the buffer memory 31. The stored data is reproduced as image data by the decoder 32 in synchronization with the operation of the decoder 32, and the buffer memory 29 And accumulate
The data is read out and printed out (image reproduction) in synchronization with the operation of the printer 33.

In the image transmission mode, the facsimile FAX uses the normal dial alcohol or the automatic dialing device to set the partner station specified on the operation / display board 27 (or whether or not the automatic dialing is specified).
24, dialing is performed by automatic dialing, a communication line is connected, an original image is read by a scanner 28, image data is generated, and the image data is stored in a buffer memory 29 and synchronized with the operation of the encoder 30. Read from the memory 29, compression-encode it, store it in the buffer memory 21,
25. Synchronize with the other party and send.

In the copy mode, the facsimile FAX reads the original image with the scanner 28 to generate image data, accumulates this in the buffer memory 29, reads it out in synchronization with the operation of the printer 33, and gives it to the printer 33. Print out a copy of the manuscript.

In the text reception mode, the facsimile FAX accumulates the received text data in the buffer memory 31 and supplies the text data to a character generator (ROM storing image data representing a character image) 34 in a predetermined sequence to give the generator 3
When the image data generated in step 4 is supplied to the frame memory device 36 via the input / output gate and the image data for one frame is written in the memory device 36, the image data is read out from the frame memory device 36 and stored in the buffer memory 29. The data is stored and synchronized with the operation of the printer 33, and the data in the memory 29 is given to the printer to print out a text image.

In the external image writing mode, the facsimile FAX designates the input / output gate 35 as a connection for writing the output image data of the switching gate 16 to the frame memory device 36, and gives the frame memory device 36 and the switching gate the image data. The control signal and the timing signal are exchanged with the source (forward monitoring device 12 or the activation control device 13 of the electric device), and the image data output from the switching gate 16 is written in the frame memory device 36.

In the external image reproduction mode, the facsimile FAX designates the input / output gate 35 as a connection for supplying the image data read from the memory device 36 to the buffer memory 29, and transfers the image data read from the frame memory device 36 to the buffer memory 29. The image data in the memory 29 is given to the printer and printed out in synchronization with the operation of the printer 33.

In the memory image transmission mode, the facsimile FAX designates the input / output gate 35 as a connection for supplying the image data read from the memory device 36 to the buffer memory 29, and transfers the image data read from the frame memory device 36 to the buffer memory 29. The operation is performed by the encoder 30 in synchronization with the operation of the encoder 30, and the compressed and encoded image data, that is, the encoded data, is accumulated in the buffer memory 31 and the operation of the transmission destination is performed. The encoded data in the memory 31 is transmitted to the destination in synchronization.

The "external image writing mode" and the "memory image transmission mode" can be instructed to the controller 17 by a key operation on the operation / display board 27. In addition, the microprocessor 2 also communicates with the serial transmission port Ss and the serial reception port Ss. The mode instruction data is serially transmitted to the controller 17 using the port Sr to give an instruction.

The control operation of the microprocessor 2 is shown in FIGS.
This will be described with reference to the drawings. First, refer to FIG.

When the power switch PSW is closed, the power circuit 1 applies a predetermined voltage to the microprocessor 2 and the power-on reset circuit 3.
To the microprocessor 2 (hereinafter referred to as “power on”).
The CPU 2 executes initialization (subroutine 1: hereinafter, the words "step" and "subroutine" are omitted in parentheses). In this initialization (1), the CPU 2 sets the internal counters, registers, flags, timers, and the like to the contents assigned during the standby state, and outputs the signal or data of the level assigned to the output port to the standby state. Set and clear the input port once. As a result of this initialization (1), the output port A ₀ is set to H (the forward monitoring device 12 is not energized).
However, L (relay 10 open) is output to the output port Ph.

When the initialization (1) is completed, the CPU 2 latches the input port, reads the input signal at that time, and instructs the stop of the abnormal (theft etc.) response image transmission (instructs by closing) to switch STS. Check if is closed. If this is open, abnormality detection (3) is performed.

Here, the content of the abnormality detection (3) will be described with reference to FIG. 3. First, the analog voltage Vs indicating the vehicle speed applied to the A / D conversion input port ADc is converted into digital data (wheel speed V
s) and read it (21). Then, it is checked whether the output Edg of the constant voltage circuit 37g is H (the ignition system power supply line Igp is connected to the battery BAT) (22),
If it is L, it is checked whether the wheel speed Vs is equal to or higher than a predetermined value Vr (the wheel is rotating) (23). If it is equal to or higher than Vr, the ignition is off (the engine is not rotating), but the wheels are rotating, so it is determined that the ignition is abnormal (the vehicle is being towed, etc.) and the contents of the register ABN are cleared ( (= Vehicle running) (24), and executes the abnormality processing of steps 4 to 17 in FIG. Wheel speed Vs is a predetermined value Vr
If it is less than the engine stop and wheel stop,
Since the state is considered to be normal, the process returns to step 2.

If the output Edg of the constant voltage circuit 37g is H at the check in step 22, the outputs Edk and E of the constant voltage circuits 37k and 37a are output.
Check if da is H (25, 26) and either is L (contact KD and / or AC is not connected to battery BAT while power line Igp is connected to battery BAT) The vehicle speed is at a predetermined value.
It is checked whether it is Vr or more (27). If it is more than Vr, the register ABN is cleared (= vehicle running) because the vehicle is running (the vehicle is running abnormally and the vehicle is running) (24), and FIG. The abnormality processing of steps 4 to 17 is executed. If the wheel speed Vs is less than the predetermined value Vr, the vehicle is not running although there is an abnormality in the vehicle, so information indicating this (abnormal In: the vehicle is not running, but the KSU is abnormal) is written to the register ABS. In (2
8) Execute the abnormal processing of steps 4 to 17 in FIG.

Summarizing here, according to the aforementioned “abnormality detection” (3), when the power supply line Igp is not at the battery voltage level (the engine is stopped) but the wheels are rotating,
The register ABN is cleared, and the process proceeds to the abnormal processing in steps 4 to 17 in FIG. 2, in which the power supply line Igp is at the battery voltage level and the contacts KD and / or AC are rotating without any battery voltage. Sometimes, the register ABN is cleared and the process proceeds to the abnormal processing in steps 4 to 17 in FIG. 2, where the power supply line Igp is at the battery voltage level and the contacts KD and / or AC have no battery voltage applied and the wheels stop. If so, "abnormality In" (the vehicle is stopped) is written into the register ABN, and the process proceeds to the abnormality processing of steps 4 to 17 in FIG.

When proceeding to the abnormal processing of steps 4 to 17, first output port
H is output to Ph (4). In response, the relay driver 9 brings the contact piece of the relay 10 into contact. Therefore, even if the power supply line Igp is not connected to the battery BAT, the former is connected to the latter via the contact piece of the relay 10. The power supply circuit of the aforementioned forward monitoring device 12, the electric device activation control device 13, the lamp controller 14, the irradiation angle controller 15, the facsimile FAX, and the car telephone radio WSR includes a power supply line Igp
Is powered on when is connected to battery BAT.

Then CPU2 switches the output of output port A ₀ from H to L (5). In response, the irradiation angle controller 15 urges the irradiation angle adjustment mechanism 22 to raise the headlamp 23,
The lamp controller 23 energizes the headlamp 23 (energizes the light), and while receiving this L, the lamp controller 23 performs automatic adjustment of the irradiation angle corresponding to the inclination angle of the vehicle body, and the energizing control device 13 of the electric device. Turns on the illumination lamp 20, outputs image data obtained by binarizing the video signal of the camera 21 and a control signal such as a reading synchronization signal to the switching gate 16, and the forward monitoring device 12 converts the video signal of the camera 19 into a binary signal. The converted image data and a control signal such as a read synchronization signal are output to the switching gate 16.

Next, the CPU 2 transmits the transmission destination data and the call instruction data to the controller 17. The transmission destination data is a telephone number registered in advance by the vehicle owner (for example, a home facsimile number, a facsimile number of a contracted security company, etc.).
It shows. In response, the controller 17 causes the automatic dialing device 24 to call (dialing) (6). The other party goes off-hook (equivalent to picking up the handset), the controller 17 exchanges the protocol with the other party, establishes a facsimile transmission and reception connection, and sets
CPU 2 outputs a gate control signal specifying "output of video information of camera 21" to switching gate 16, and transmits data indicating "external image writing mode" described above to controller 17 I do. In response, the controller 17 instructs the input / output gate 35 and the frame memory device 36 to write the output image data of the switching gate 16, and notifies the memory device of the end of the writing of the image data of one frame.
When notified by the controller 36, the controller 17 sends data indicating the end of writing to the CPU 2 (7).

Upon receiving the write end, the CPU 2 transmits data specifying the “memory image transmission mode” described above to the controller 17 in response to this. The controller 17 executes the “memory image transmission mode” here, and when the transmission of the image data of one frame of the frame memory device 36 to the destination is completed, the controller 17 outputs data indicating the end of the frame data transmission.
Send to CPU2 (8).

As described above, the image (one frame) of the driver's seat (the face of the seated person) captured by the camera 21 is transmitted to the other party.

When receiving the data indicating the end of the frame data transmission from the controller 17, the CPU 2 checks whether the switch STS is closed (9), and if the switch STS is open, the content of the register ABN is “abnormal In”. Check if there is (vehicle is not running) (10). If it is “abnormality In”, the process proceeds to the “abnormality detection” subroutine 14. The contents of the subroutine 14 are the same as the contents of the above-mentioned subroutine 3 of "abnormality detection". When an abnormality ("Abnormal In") is detected in the "abnormality detection" (14) in the same manner as in the previous detection (3), the "external image writing mode" (7) and the "memory image transmission mode" (8) are executed. .

By the above operation, while detecting "Abnormal In",
One frame of image data captured by the camera 21 at a predetermined cycle is repeatedly transmitted to the other party. When someone is sitting in the driver's seat, an image of the person's face is transmitted to the other party. If the destination is a facsimile, the face image is printed out online. If the other party is a monitoring station with a CRT display and video recorder, the CRT
And recorded on a video recorder.

By the way, when the content of the register ABN is checked in step 10 and it is not "abnormal In", the switching gate 16 is set to give the image data of the camera 19 to the memory device 36, and the same as in the subroutine 7 described above. Then, the data of one frame image captured by the camera 19 is written into the frame memory device 36 (11), and then the subroutine 8
Similarly, the image data in the memory device 36 is transmitted to the destination (12). Then, it is checked whether or not the switch STS is closed (13). If the switch STS is open, the process proceeds to a subroutine 14 of "abnormality detection". When an abnormality is detected in the "abnormality detection" (14) as in the previous detection (3) ("No abnormality In" is detected), "external image writing mode" (7), "memory image transmission mode" (8), " The external image writing mode ”(11) and the“ memory image transmission mode ”(12) are executed. By the above operation, one frame of image data captured by the camera 21 and one frame of image data captured by the camera 19 are alternately and repeatedly transmitted to the other party in a predetermined cycle. When someone is sitting in the driver's seat, the image of the person's face and the scene in front of the traveling vehicle are alternately transmitted to the other party. If the other party is a facsimile, the image of the face and the front of the vehicle are transmitted. Scenes are alternately printed out online. If the other party is a monitoring station having a CRT display and a video recorder, those images are displayed on the CRT display and recorded on the video recorder.

When the switch STS is closed during the transmission of the image data as described above, the CPU 2 detects this in step 9 or 13 and sends an “off-hook (return of the handset; disconnection of the communication circuit)” to the controller 17. Instruct. The controller 17 disconnects the communication line here (15). CPU2 is then switches the output port A ₀ to H (16). With this, the forward monitoring device 12
Stops the energization of the camera 19 and the energization control device 13 of the electric device.
Turns off the illumination lamp 20, stops the energization of the camera 21, the lamp controller 14 stops the energization of the headlamp 23, and the irradiation angle controller 15 energizes the irradiation angle adjustment mechanism 22 to retract (retract). However, by these electrical devices itself operation switch, when the biasing is indicated, even if the signal output port A ₀ becomes H, including operation (biasing in accordance with the instruction of the operation switch ) To continue. This causes the L output port A _0, the each apparatus for the internal wiring, because instruction of the operation switch of each device and (L) is to give the relation of logical OR .

CPU2, after a predetermined time the output of output port A ₀ from switching from L to H (time sufficient headlamp returns to the retracted position from the standing position) and returns the output port Ph from H to L. Thereby, the urging of the relay driver 9 is stopped, and the contact piece of the relay 10 is opened. At this time, if the power supply line Igp is not connected to the battery BAT by other means (for example, the rotor ROR), the power supply line Igp is disconnected from the battery BAT, and the mobile phone radio WSR, facsimile FAX, forward monitoring device 12
The power supply to the power supply circuits of the (and the camera 19), the power controller 13 (and the (camera 21), the lamp controller 14, and the irradiation angle controller 15) is cut off.

The CPU 2 also executes steps 15 to 17 when the normality is detected in the subroutine 14.

The wheel speed detection circuit 6 and the relay driver 9 are supplied with power from the power supply circuit 1, and when the operating voltage is supplied to the microprocessor 2, the required voltage is similarly supplied.

To stop the transmission of the image data in response to the above-described abnormality detection, the switch STS may be closed. When the switch STS is closed, as described above, the CPU 2 detects this in step 9 or 13, and stops the transmission in steps 15 to 17.

If the switch STS is closed when the initialization (1) is executed, the CPU 2 transmits text data indicating an automatic dial instruction and a warning to the controller 17. Upon receiving this, the controller 17 sends an ACK to the CPU 2,
The text data is converted into image data by the character generator, written into the buffer memory, the destination designated for automatic dialing is called by the automatic dialing device 24, the image data in the buffer memory 29 is transmitted to the destination, and the transmission is performed. When finished, the line is disconnected (18). When the CPU 2 receives the ACK signal (19), it checks whether the switch STS is open or closed (2).
0), if it is closed, it stands by. Switch STS
Is opened, the process proceeds to initialization 1, and the above-described abnormality is detected (3).
Do the following:

By the control operation of the CPU 2 described above, the switch PSW
Is closed and the switch STS is open, the voltage of the ignition system power supply line Igp is below a predetermined value (Edg is L; Igp is BAT
When the wheels 4 are rotated when the camera 4 is not connected to the communication destination, the image captured by the camera 21 and the image captured by the camera 19 are transmitted to the communication destination registered in advance in the CPU 2, the controller 17 or the automatic dial device 24. Sent by wireless phone.

Therefore, if a person trying to steal the vehicle pushes or pulls the vehicle without turning on the engine (does not insert a key into the key cylinder) and rotates the wheels, the person sitting in the driver's seat in the vehicle (that The image of the face (if any) and the scene in front of the vehicle are automatically transmitted to the communication destination.

When the switch PSW is closed and the switch STS is open, the voltage of the ignition system power supply line Igp exceeds a predetermined value (Edg
Is H; Igp is connected to BAT) and key cylinder KSU
When the voltage of the contact KD and / or the contact AC is less than a predetermined value (Edk or Eda is L) and the wheel is rotating,
As described above, the image captured by the camera 21 and the image captured by the camera 19 are transmitted to the communication destination by wireless telephone. When the wheels are not rotating, only images taken by the camera 21 are transmitted to the communication destination.

Therefore, if a person trying to steal the vehicle enters the vehicle by illegal means and connects the ignition system power supply line Igp to the battery BAT by illegal means, before the vehicle starts, the face of the person sitting in the driver's seat The image is transmitted to the destination by wireless telephone. When the vehicle is started, the image of the face of the person sitting in the driver's seat and the scene ahead of the vehicle are automatically transmitted to the communication destination.

In the communication destination, for example, in a mode of receiving and printing out online by facsimile, the face of the person sitting in the driver's seat is printed out every screen (one page) or the scene in front of the vehicle is printed out alternately every screen. Is done. At the communication destination, therefore, the face of the person sitting in the driver's seat can be used to identify the culprit if the vehicle is stolen. The scene ahead of the vehicle can be used to determine the position of the vehicle.

〔The invention's effect〕

As described above, according to the vehicle information transmitting apparatus of the present invention, the image data of the image of the driver of the stolen vehicle or the scene ahead of the vehicle can be automatically obtained at a position away from the vehicle. It is easy to specify or to determine the current vehicle position.
