S-1000) (manufactured by OMRON) can be used. This device reads a fingerprint with an optical sensor, sends the read information to a computer equipped with fingerprint collation application software, and performs personal recognition by collating it with data previously stored in the computer. A USB interface is used as an interface with the computer. At present, fingerprint sensors are being miniaturized, and are disclosed in JP-A-6-149983 and JP-A-6-149983.
223163, JP-A-8-334636, JP-A-1
It is considered that a smaller sensor can be obtained by using the technology disclosed in Japanese Patent Application No. 0-171968.

The fingerprint recognition device 1 is provided integrally with the buckle 3 of the seat belt. This buckle 3 is supported by the left hand when the seat belt 5 is worn, and the tongue 7 of the seat belt held by the right hand is fitted. A groove 9 is formed on the side surface of the buckle 3 for easy gripping. The upper surface is formed with a shallow depression 11 on which a thumb can be placed, where a fingerprint of the thumb is detected. When the buckle 3 is supported by the left hand, four fingers other than the thumb are put into the grooves 9, and the thumb is naturally placed on the recess 11. Therefore, the fingerprint can be detected simultaneously with the operation of wearing the seat belt. The fingerprint detection unit is provided in the groove 9, and can detect fingerprints of four fingers other than the thumb. When the groove 9 has an L-shaped cross section and a fingerprint detection unit is provided outside the groove cut upward, four fingers other than the thumb are inserted into the groove 9 and the buckle is grasped. In this case, fingerprints of four fingers can be detected in a more natural state. Furthermore, the groove 9
The other side of the buckle 3 is used as a fingerprint detection unit. When a large occupant squeezes the buckle 3, even if four fingers other than the thumb turn to the opposite side of the buckle 3, a fingerprint is detected. Detection can also be enabled.

Such a fingerprint recognition device is provided on a buckle portion of a seat belt of all seats in a vehicle.

Next, the example of FIG. 1B will be described. The fingerprint recognition device of the present invention includes a fingerprint sensor 1 'for reading a fingerprint with an optical sensor. The information read by the fingerprint sensor 1 'is sent to a computer equipped with fingerprint collation application software. Here, personal recognition is performed by collating with data stored in the computer in advance.

The fingerprint sensor 1 ′ is provided integrally with the tongue 7 of the seat belt 5. The tongue is supported by the right hand when the seat belt is worn, and is fitted to the buckle 3 of the seat belt held by the left hand. The surface of the tongue 7 is formed with a shallow depression 13 on which the index finger can be placed, where the fingerprint of the index finger is detected. Therefore, the fingerprint can be detected simultaneously with the operation of wearing the seat belt.

As described above, by using a device that recognizes a fingerprint unique to an individual, individual recognition can be reliably performed. Further, by attaching this fingerprint recognition device to a buckle, tongue, or the like that is inevitably touched by a finger when wearing a seat belt, it is not necessary to force the occupant to perform an independent operation. Further, there is no need to force the occupant to perform an independent operation. Furthermore, there is no need to carry an ID card at all times, and it is not necessary to insert an ID card while driving or to input an ID number from a keyboard to reduce the driver's attention.

FIG. 2 is a block diagram of a computer for controlling the operation of the fingerprint recognition device and the occupant protection device according to the first embodiment of the present invention. The computer is a central processing unit 5
0, a fingerprint input unit 60, an information input unit 70, a storage unit 80, and the like, and are mounted on a vehicle.

The information input unit 70 is an input device 71 such as a keyboard, and has physical characteristics such as weight, height, age, gender, presence or absence of osteoporosis, presence or absence of pregnancy, etc. of the occupant who has been authorized by the owner or family of the vehicle. Is entered for each occupant. All the input information is stored in the personal information data storage unit 82. Since such personal information needs to be updated or changed, a rewritable RAM is used as a recording medium.
The database of the personal information storage unit 82 stores not only physical characteristics such as height and weight, but also detailed personal information such as osteoporosis, decrease in skeletal strength due to old age, characteristics and health status of each individual such as during pregnancy. The occupant protection device can be adjusted according to the information to provide more optimal and safe occupant protection. Further, the information input unit 70 includes a fingerprint sensor, and the fingerprint data of the occupant who has obtained the above-mentioned permission is read and stored in the fingerprint data storage unit 81. Since the fingerprint data may be updated or changed, a RAM is used as a storage medium. This fingerprint data corresponds to the above-described personal information data, and personal information and fingerprint data for the occupant who has obtained permission are input and stored in the storage unit 80.

The input device 71 may be a separate computer which can be connected to the vehicle computer by communication means such as a cable. The occupant's personal information and fingerprint data are input to the input computer in advance, sent to the vehicle computer by communication means, and each data is stored in the storage unit 80. Thus, it is not necessary to provide an information input unit in the vehicle computer, and the computer of the vehicle can be downsized.

The information input unit 70 may be configured to read an ID card into which personal information data or fingerprint data of a specific occupant has been input by a computer of the vehicle. In this case, the personal information and fingerprint data of the occupant are read by a separate input device in advance and stored in the ID card. Then, the card of each occupant is read by the computer of the vehicle, and each data is stored in the storage unit 80. If this operation is performed once, there is no need to carry an ID card for each drive or ride.

The fingerprint sensor 61 of the fingerprint input unit 60 is provided on a seat belt of each seat of the vehicle. The fingerprint sensor 61 is of the same type as the fingerprint sensor of the information input unit 70. The fingerprint of each occupant is read from this sensor and collated with the fingerprint data stored in the fingerprint data storage unit 81. Data collation is performed by the fingerprint collation application software 62.

The occupant protection device optimization program 83 is installed in the ROM of the storage unit. The program 83 shows a method for optimizing the occupant protection device in accordance with data relating to physical characteristics stored in the personal information data storage unit 82, which is input from the information input unit 70. The occupant protection device 90 is an airbag, a seat belt pretensioner, an EA, an air belt, or the like, and the parameters of each device are optimized according to physical characteristics. For example, in the parameter of the deployment power of the airbag, the deployment power is O with respect to the weight which is one of the physical characteristics.
An instruction is given to be in one of the three stages of FF, 1st, and Full (a specific example will be described later). Further, the program 83 shows a method for optimizing the occupant protection device according to the information of the seat position, the occupant posture, and the collision severity sent from the seat sensor, the occupant sensor, and the collision sensor. . These instructions are sent from the central processing unit 50 to each occupant protection device 90.

The central processing unit 50 is constituted by a microprocessor and has a control program 51 stored in a ROM.
Along with the process of retrieving the personal information data of the occupant corresponding to the fingerprint from the fingerprint data for a certain occupant, and the process of transmitting the optimized set value of the occupant protection device to each occupant protection device, and performing the above-described setting and command. .

FIG. 3 is a flowchart showing the operation of the central processing unit of the occupant recognition device and the occupant protection device according to the first embodiment of the present invention. In this example, a flow of processing for obtaining an access right to the optimization of the occupant protection device by fingerprint recognition will be described.

In this device, the fingerprint data of the owner of the car or the occupant who has obtained permission in advance is input by the fingerprint sensor of the information input unit and stored in the fingerprint data storage unit. Further, the physical characteristics of each occupant are input from the input device and stored in the personal information data storage unit. When the program is started, first in S1, a fingerprint is detected by a fingerprint sensor. Next, in S2, the detected data is compared with the fingerprint information stored in the fingerprint data storage unit, and if there is matching data, it is determined that the vehicle is an authorized occupant, and the process proceeds to S3, where the occupant protection device is provided. Run the optimization program. If the data detected at this time is not stored in the storage unit, the optimization of the occupant protection device is not performed, and the program ends. When the occupant protection device optimization program operates, in S4, the personal information of the occupant corresponding to the fingerprint data is called from the personal information data storage unit based on the fingerprint data detected in S1. Next, in S5,
Determine the optimized parameters of the occupant protection device for each personal information. This parameter is sent to each occupant protection device in S6, and each device is adjusted and controlled.

According to this example, if the fingerprint detected by the fingerprint sensor is not the one that has been approved in advance, the occupant protection device is not optimized, and the safety performance is reduced. Further, in this case, a security function is added by giving an instruction for restricting the driving function, including starting and stopping the engine.
In the case where an occupant who has obtained permission and who has not registered fingerprint data and personal information data gets on the board, the personal information data including at least one of height, weight, age, gender, and pre-existing illness is input from the information input unit 70 at the time of boarding. Is stored in the personal information data storage section 82 of the storage section.
And the fingerprint data can be stored in the fingerprint data storage unit 81.

Next, an example of the flow of processing for determining the operation of the airbag, the pretensioner, and the EA, which are occupant protection devices, in the occupant protection device optimization program will be specifically described. The operation parameters of each device, ie, the airbag deployment force, the pretensioner retraction force, and the EA load, are adjusted stepwise according to the occupant's physique and skeletal strength. In this example, it is assumed that physique is mainly dependent on weight and skeletal strength is mainly dependent on age.

The body weight is divided into four stages: 22 kg or less, 50 kg or less, 75 kg or less, and 75 kg or more. Further, C
A section called RS is also provided. The higher the weight, the better the physique. In addition, the skeletal strength is 6 years or younger and 60 years or older for men, 6 years or younger and 50 years or older for women,
It is divided into two stages: 6-50 years old for men and 6-60 years old for women. In the former case, the skeletal strength is determined to be weak, and in the latter case, it is determined to be strong. Here, for example, even if it is determined that the weight is heavy and the physique is good, if the age is male, 60%
If the age is 50 or older, it is determined that the skeletal strength is weak, and the operating parameters of each occupant protection device are adjusted based on these two results.

FIG. 4 shows the airbag deployment force, the pretensioner retraction force, and the skeletal strength and physique classification.
It is a figure showing the example of setting of EA load. The skeletal strength was strong, and the setting was based on weight.

In general, when the physique is good, it is appropriate that the airbag deployment force is appropriate (Full), the pretensioner retraction force is high (High), and the EA load is strong (High). The stronger the skeletal strength, the stronger the airbag deployment force (Full), and the stronger the pretensioner retraction force (H
i), the EA load becomes strong (Full). However,
Women weighing 75 kg or more and ages 50 or older or 60
When the skeletal strength is weak even if the physique is good, such as in the case of a man over the age of, the pretensioner is set to expand to a low level (Low) to reduce the burden on the skeleton, and the EA is set to a high level (High). The upper body is set to fall slowly and fall into the inflated airbag in a timely manner.

Therefore, in the occupant protection device optimization program, the weight and age are called from the personal information data, and the combination thereof is made to correspond to the setting in Table 1, and
Airbag deployment force, pretensioner pull-in force, EA
Set the weight.

Further, depending on a special situation such as pregnancy or osteoporosis, such information is called out prior to the physique and age, and an appropriate treatment is performed. That is, in the case of pregnancy, the airbag deployment force is usually normal, the pretensioner retraction force is usually normal, and the EA load is weak. In the case of osteoporosis, the airbag deployment force is usually low, the pretensioner retraction force is weak, and the EA load is normal.

FIG. 5 is a schematic diagram showing a state in which a fingerprint recognition device according to another embodiment of the present invention is attached to a window opening / closing button of a door. This fingerprint sensor 1 ″ has a window opening / closing button 15.
And are provided integrally. A shallow depression 17 is formed on the surface of the button 15, and the fingerprint is detected here.

In this case, whether or not a seat belt is worn is also involved in setting other occupant protection devices. FIG. 6 is a diagram showing an example of setting an airbag deployment force in each case of whether or not a seatbelt is worn. In this case, there is no need to adjust the airbag deployment force according to the skeletal strength.

Accordingly, in the occupant protection device optimization program, the weight and age are called from the personal information data, and the combination of the weight and the presence or absence of the seat belt is set in accordance with the settings in Table 2, and the airbag deployment force is set. .

Further, the sheet position,
If the parameters of each occupant protection device are selected by adding the information of the occupant's posture and the collision severity, more appropriate protection can be provided.

The above-described occupant recognition device and occupant protection device can also be applied to an airplane seat. For example, if you register height, weight, age, gender, medical history, etc. when you book an airplane, a seat belt pretensioner or EA overweight corresponding to your physical characteristics will be set according to your seat number. You.
