Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a vehicle antitheft system that enables engine start when acquiring fingerprint data of a person who has entered a vehicle, and transfers the fingerprint data to a reception storage processing device through a communication network for storage.
[0002]
[Prior art]
2. Description of the Related Art Conventionally, various keyless entry systems are known in which a portable transmitter is approached and operated to transmit a personal identification code, and a vehicle door is locked and unlocked without using a door key. As this keyless entry system, a technique for unlocking a vehicle door lock by fingerprint identification has been proposed (for example, Japanese Patent Application Laid-Open No. 61-53972 “A method for unlocking an automobile door by fingerprint identification”) Sho 61-64977 “Solid identification automobile door opening / closing device” publication example, Japanese Patent Laid-Open No. 62-101777 “Electronic key device” publication example).
[0003]
In the door lock unlocking by this kind of fingerprint identification, the fingerprint identification ability becomes a problem. For example, since it is provided on the door of the fingerprint recognition apparatus outside the vehicle, the fingerprint identification ability is reduced due to dirt on the reading optical system, adhesion of water, etc., and damage or dirt on the finger of a person who performs fingerprint recognition. Further, since complicated pattern recognition processing is performed, it takes a long time for fingerprint identification, and it is known that the probability of erroneous recognition increases when the identification time is shortened.
[0004]
As a vehicle theft countermeasure, a vehicle theft countermeasure system based on a communication network combining a mobile phone, a global positioning system (GPS), a security service, and a radio selective call receiver (pager) has been proposed ( (See Automotive Engineering International / October 1998). This vehicle theft countermeasure system requires a dedicated device together with the keyless entry system, which increases the cost and may cause a malfunction.
[0005]
[Problems to be solved by the invention]
As described above, a more reliable system construction is a problem in a vehicle theft countermeasure system based on communication networking, and further improvement in safety against vandalism and vehicle theft (which will be described only by vehicle theft as appropriate) is desired. .
[0006]
The present invention solves such a problem in the prior art, and enables the engine to be started when fingerprint data of a person who has entered the vehicle is acquired, and the fingerprint data is separated from the vehicle through a communication network. Transfer and store to the reception storage processing device provided at the place, it is possible to easily confirm the person who got into the vehicle at the position away from the vehicle from the transferred fingerprint data, security performance against vehicle theft etc. An object of the present invention is to provide a vehicle antitheft system that can be improved.
[0007]
[Problems to be solved by the invention]
To achieve the above object, the vehicle anti-theft system of the present invention controls fingerprint capture means for acquiring human fingerprint data and automatic transmission of fingerprint data obtained by the fingerprint capture means to a communication network. A transmission control unit that performs wireless transmission of fingerprint data obtained by the fingerprint capture unit to the communication network in response to control performed by the transmission control unit, and the communication from the wireless communication unit to the communication and an information storage means for storing received fingerprint data transmitted over the network, starting the engine of the vehicle, the fingerprint capturing means is in the authorized Ru configured when acquired fingerprint data.
[0008]
The fingerprint capturing means includes an optical reading device that optically reads a human fingerprint, and a detection unit of the optical reading device is arranged in the vehicle.
[0009]
Further, the engine start of the vehicle is permitted when the fingerprint capturing means acquires fingerprint data.
[0010]
In such a vehicle antitheft system of the present invention, after fingerprint data of a person who has entered the vehicle is acquired by a fingerprint capture means in the vehicle, the fingerprint data is automatically transmitted to a communication network and transmitted via the communication network. The fingerprint data thus held is held in an information storage means such as a server. Also, the engine start of the vehicle is permitted when the fingerprint capture means acquires fingerprint data.
[0011]
For this reason, it is necessary for a passenger in the vehicle to supply fingerprint data every time permission to start the engine is obtained. Since the obtained fingerprint data is transmitted to the information storage means through the communication network every time, the vehicle is stolen. Even in this case, since the fingerprint data held in the information storage means can be referred to and confirmed, it is possible to quickly and easily identify the criminal and solve the case. Moreover, the anti-theft effect of the vehicle can be obtained by publicly publishing that the fingerprint data obtained by the fingerprint capturing means is stored.

[0027]
Next, the operation of this embodiment will be described.
First, in the keyless entry system, when a person having the portable transceiver 4 approaches the vehicle 1, the vehicle-side transceiver 2 is activated by a signal transmitted from the portable transceiver 4 by an unillustrated proximity sensor, and the vehicle-side transceiver The machine 2 transmits a response signal to the portable transceiver 4. When the portable transmitter / receiver 4 receives the response signal, the portable transmitter / receiver 4 transmits a remote operation signal including a password to the vehicle-side transmitter / receiver 2. Next, authentication of the code is performed in the vehicle-side transceiver 2 and when the code is correctly authenticated, the in-vehicle computer 5 controls the drive mechanism 3 to release the door lock.
[0028]
Next, when a person who gets into the vehicle 1 places a finger on the transparent base 11a of the fingerprint capturing device 11 provided in the driver's seat or the like, the switch 11b is mechanically Optical detection is performed, and this detection signal is sent to the in-vehicle computer 5. The in-vehicle computer 5 that has captured the detection signal drives the image sensor 11c, optically reads the fingerprint of the passenger on the transparent base 11a, and the in-vehicle computer 5 captures the photoelectrically converted fingerprint data.
[0029]
Next, the in-vehicle computer 5 obtains date / time data from a calendar (timer) circuit (not shown), adds the date / time data to the captured fingerprint data, and transfers the fingerprint data with the date / time data to the server device 36 registered in advance. At this time, the in-vehicle computer 5 transmits these data using the mobile phone 8 after a link is established between the mobile phone 8 and the server device 36 by a communication protocol.
[0030]
Next, the server device 36 stores these data in the hard disk device 36a and displays these data on the image display device 36b immediately or when there is a display command by the input device 36c.
[0031]
As described above, according to the vehicle antitheft system of this embodiment, every time a fingerprint of a person who has entered the vehicle 1 is captured by the fingerprint capture device 11, the fingerprint data is transferred from the mobile phone 8 to the server device 36. Since it is stored, even when the vehicle 1 is stolen, the fingerprint data held in the server device 36 can be referred to and confirmed, and the criminal identification and the case resolution can be performed quickly and easily. . Moreover, the anti-theft effect of the vehicle 1 can also be obtained by publicly publishing that the fingerprint data captured by the fingerprint capture device 11 is stored.
[0032]
In addition, individual vehicle information (for example, vehicle number / number plate number, vehicle name) and information on the parking location are input from the mobile phone 8 or the mobile computer 6 and added to the fingerprint data and transferred to the server system. You may do it. In this case, since the server system can individually take countermeasures against theft of a plurality of vehicles, it becomes easier to solve the vehicle theft.
[0033]
In this embodiment, the case where fingerprint data is transferred from the vehicle 1 has been described. However, image data taken in the vehicle (particularly around the driver's seat) taken by the CCD camera 7 is transferred to the server system in the same manner as the fingerprint data. Also good.
[0034]
Further, information such as characters and voices indicating that the door lock of the vehicle 1 has been released is transmitted to the mobile phone 33, the radio selective call receiver 34, the vehicle manager's home or office computer, and the server system. May notify the vehicle manager that the door lock has been released. In response to this notification, it is also possible to operate the CCD camera 7 by remote control to capture image data in the vehicle.
[0035]
In addition, since the fingerprint capture device 11 used in the present embodiment does not perform fingerprint recognition itself, it is not necessary to perform complicated data processing necessary for unlocking a conventional vehicle door lock. Therefore, in the present embodiment, regardless of factors relating to fingerprint recognition such as the time required for fingerprint pattern recognition, the fingerprint identification processing speed, and the recognition rate, a person who has entered the vehicle 1 as in the past (for example, No need to pre-register fingerprints as drivers). Furthermore, since the fingerprint capture device 11 is disposed in the vicinity of the driver's seat and is not disposed outside the vehicle 1 unlike the conventional fingerprint recognition device, the fingerprint capture device 11 receives light from the transparent base 11a and the image sensor 11c of the fingerprint recognition device. A margin can be made larger than that in the past with respect to deterioration of fingerprint identification capability due to surface contamination or water adhesion.
[0036]
【The invention's effect】
As is apparent from the above description, according to the vehicle antitheft system of the present invention, after the fingerprint data of the person who has entered the vehicle is acquired by the fingerprint capturing means in the vehicle, the fingerprint data is automatically transmitted to the communication network. The fingerprint data transmitted via the communication network is held in an information storage means such as a server. For this reason, even when the vehicle is stolen, the fingerprint data held in the information storage means can be referred to and confirmed, so that the criminal can be identified quickly and easily resolved. Moreover, the anti-theft effect of the vehicle can be obtained by publicly publishing that the fingerprint data obtained by the fingerprint capturing means is stored.
