(Configuration of start switch 5)
The start switch 5 is disposed, for example, in front of an operator seated in a driver's seat, or on a floor console located between the driver's seat and a passenger seat. The start switch 5 instructs the vehicle to start or prepare to start the drive of the vehicle by a push operation (on operation) performed on the operation surface 50, and then the drive by a push operation (off operation) performed thereafter. To stop the

  Specifically, when the drive device is an internal combustion engine (engine), the engine is started by a push operation performed in a state where the operation conditions of the shift device and the brake device are satisfied. In addition, when the drive device is a motor, preparation for starting operation for supplying current to the motor is performed by the push operation performed in the state where the above operation conditions are satisfied. Furthermore, when the drive is a hybrid of an engine and a motor, the push operation performed in the state where the above-described operation conditions are satisfied makes a start or start preparation corresponding to the drive to be prioritized at the time of start. The off operation performed after the on operation instructs a stop of the drive device. The start switch 5, the shift device, the brake device, and the drive device are connected to, for example, a vehicle control unit 22 shown in FIG.

(Configuration of biometric information reading unit 10)
The biometric information reading unit 10 is disposed below the operation surface 50 of the start switch 5 and configured to read the biometric information 100 of the operating finger in contact with the operation surface 50. The biometric information 100 includes, as an example, information on at least one of a fingerprint pattern of an operating finger and a vein pattern.

  For example, when reading a fingerprint pattern, the biological information reading unit 10 uses a sensor configured to read a fingerprint pattern such as an optical type, a capacitance type, an electric field strength measurement type, a pressure-sensitive type, or a thermal type.

  When reading a vein pattern, the biological information reading unit 10 uses, for example, a sensor configured to read the vein pattern based on the reflection of the irradiated near-infrared light.

  Furthermore, when reading both the fingerprint pattern and the vein pattern, for example, the biological information reading unit 10 is a sensor configured to perform image processing on an image captured by emitting visible light and extract the fingerprint pattern and the vein pattern. Used.

  The biometric information reading unit 10 according to the present embodiment is, for example, a capacitive sensor that reads a fingerprint pattern. The biometric information reading unit 10 outputs, to the control unit 18, biometric information 100 which is information of the read fingerprint pattern.

(Configuration of registration reading unit 12)
As an example, as shown in FIG. 1B, the registration reading unit 12 is schematically configured to include a set button 120 and registration buttons 121 to 123 arranged in the vicinity of the start switch 5. The set button 120 and the registration button 121 to the registration button 123 are, for example, configured as push buttons, but are not limited to these and may be touch switches.

  The set button 120 and the registration button 121 to the registration button 123 are a group of buttons to be pressed when registering the setting of each in-vehicle apparatus adjusted by the operator to his preference, that is, when registering the vehicle setting and calling the registered vehicle setting. .

  As an example, as shown in FIG. 3, the on-vehicle device includes a steering adjustment device 24, a seat adjustment device 26, a mirror adjustment device 28, a vehicle periphery imaging device 30, a collision warning device 32, a touch panel 34, a display device 36, and a touch pad 38.

Further, for example, when the vehicle control unit 22 can set settings such as the number of items and types of menus displayed on the display device 36, the vehicle setting device 1 registers the settings in the vehicle setting table 160 as the vehicle settings.

  On the set button 120, as one example, the characters "SET" are printed. The letters “A” to “C” are printed on the registration button 121 to the registration button 123 as an example. The “A” to “C” indicate registrants A to C. The number of registration buttons and the number of registrants that can be registered are arbitrary.

  Here, when the operator registers the current vehicle setting, as an example, after the set button 120 is pressed, the registration is performed by pressing the registration button for which the vehicle setting is to be registered. In this registration operation, the biometric information 100 when the start switch 5 is turned on is stored as the registered biometric information 140. After the registration, when the operator gets into the vehicle and turns on the start switch 5, the biometric information 100 of the operator and the registered biometric information 140 are collated. For example, when the operator is the registrant A, registration is performed The vehicle settings set by person A are read out.

  When it is desired to read out the vehicle settings previously registered by the operation of the registration reading unit 12, as an example, after pressing the registration button in which the vehicle settings are registered, registration related to the registration button pressed by pressing the set button 120 The vehicle setting of the person is read.

  The set button 120 and the registration button 121 to the registration button 123 are configured to light up or blink, for example. For example, when the operator is an unregistered person, the control unit 18 lights or blinks a registration button in which the vehicle setting is not registered in order to notify the registration operation. In addition, for example, when the registered vehicle setting is read, the control unit 18 lights or blinks the registration button that has already been registered. This notification may be performed by, for example, a voice message output from a speaker of the vehicle, may be performed by displaying a message image on a display device, or may be performed in combination with lighting or lighting.

Registering reading unit 12 is, for example, generates registration read information S ₁ corresponding to the combination of the pressed button, and outputs it to the control unit 18. Control unit 18, whether the registration operation of the vehicle setting has been made, it is determined whether the read operation is performed and take appropriate action based on the registration read information S _1.

Note registering reading unit 12 is, for example, when the registration button 121 is pressed, generates a registration read information S ₁ of the operator pressing the registration button 121 as a registered person A. Similarly, registration readout unit 12, for example, when the registration button 122 is pressed, if generates registration read information S ₁ of the operator pressing the registration button 122 as a registered person B, the registration button 123 is pressed , generates the registration read information S ₁ of the operator pressing the registration button 123 as registrant C.

  As a modified example, the vehicle setting device 1 may perform registration and readout of vehicle settings of more than three registrants, for example, by operating a plurality of registration buttons, in accordance with the combination of pressed registration buttons. It may be configured to be able to.

(Configuration of storage unit 14)
The storage unit 14 is a semiconductor memory as an example. The storage unit 14 stores registered biometric information 140 for each registrant. The storage unit 14 may be, for example, a random access memory (RAM) included in the control unit 18.

  The registered biometric information 140 is biometric information 100 read at the time of the on operation performed immediately before the registration operation. More specifically, the registered biometric information 140 is, for example, information in which the read biometric information 100 is associated with the registrant indicated by the registration button pressed in the registration operation.

  When the biometric information reading unit 10 reads a vein pattern, the registered biometric information 140 becomes information of the vein pattern instructed to be registered, and when reading a fingerprint pattern and a vein pattern, the fingerprint pattern and vein pattern instructed to be registered. Information.

(Configuration of control unit 18)
The control unit 18 is a microcomputer including, for example, a central processing unit (CPU) that performs computations, processing, and the like on acquired data according to a stored program, a RAM that is a semiconductor memory, and a read only memory (ROM). is there. In the ROM, for example, a program for operating the control unit 18, an identification threshold 180, and an update threshold 181 are stored. The RAM is used, for example, as a storage area for temporarily storing operation results and the like.

  The control unit 18 collates the biometric information 100 acquired from the biometric information reading unit 10 with the registered biometric information 140 acquired from the storage unit 14 and determines which registrant the vehicle operator is or an unregistered person. It is configured to identify if there is any.

  As an example, control unit 18 determines in advance the similarity between the feature point of the fingerprint pattern of the operator based on biometric information 100 and the feature point of the fingerprint pattern of the registrant registered in registered biometric information 140. If the threshold value is 180 or more as the threshold value, it is determined that the operator is a registrant.

  The feature points are, for example, four points called a center point 110, a branch point 111, an end point 112, and a triangular state 113, as shown in FIG. 2A. The center point 110 is a point that is the center of the fingerprint pattern 90 shown in FIG. The branch point 111 is a point at which the ridge of the fingerprint branches. The end point 112 is a point at which a ridge is broken. The triangle 113 is a point where ridges gather from three directions. The control unit 18 collates based on the position of the feature point, the distance between the feature points, and the like to calculate the similarity.

  The control unit 18 collates the feature points of the fingerprint pattern of the biometric information 100 and the registered biometric information 140, determines the similarity according to the number of matching feature points, and determines whether the operator is a registrant or not yet Identify if you are a registrant.

  Specifically, as an example, the control unit 18 has 50 feature points of the fingerprint patterns of the registrant A to the regist C based on the registered biometric information 140, and corresponds to the feature points of the fingerprint pattern of the operator If there are 40 registrants A, 20 registrants B and 33 registrants C, the similarity to registrant A is 80 (%) and the similarity to registrant B is 40 (% And the similarity to registrant C is calculated to be 66 (%). As an example, when the identification threshold 180 is 70 (%), the control unit 18 determines that the operator is the registrant A.

  The control unit 18 registers the operator having the newly read biometric information, when the collation is established based on the common part of the newly read biometric information 100 and the registered biometric information 140 as described above. It is assumed that the registrant has registered the biometric information 140.

  Specifically, as an example, as shown in FIG. 2B, the control unit 18 has a registration area 141 which is an area of the fingerprint pattern of the registered biometric information 140 registered, and the biometric information newly read. Whether the operator is a registrant if the similarity of the feature points in the matching area 185 where the reading area 101, which is the area of the 100 fingerprint patterns, intersects the identification threshold 180 or more judge.

  If the positional deviation between the registration area 141 and the reading area 101 is large or the area of the registration area 141 is small, the number of feature points included in the collation area 185 may be small and the determination accuracy may be degraded.

  Therefore, the control unit 18 expands the registration area 141 when the similarity in the collation area 185 is equal to or more than the update threshold value 181. The reading area 101 shown in FIG. 2B has a non-matching area 102 which is an area other than the matching area 185 intersecting with the registration area 141.

  The non-matching area 102 is an area that is not used for the present matching. The control unit 18 combines the registration area 141 and the non-matching area 102 to generate the extended registration area 142 shown in FIG. In other words, the image based on the registered biometric information 140 and the image of the newly read biometric information 100 are combined to newly generate registered biometric information 140. The control unit 18 stores the extended registration area 142 as new registered biometric information 140 in the storage unit 14 and uses it for the next matching.

  The extended registration area 142 is expanded every time the contact area between the operation surface 50 and the operating finger changes each time the operation of the registrant varies. Further, as shown in FIGS. 2B and 2C, the extended registration area 142 has a wider area than the registration area 141 before the expansion, and includes many feature points. Therefore, the determination accuracy is improved if the control unit 18 performs determination using the extended registration area 142, rather than using the registration area 141 before extension.

  The control unit 18 is also electromagnetically connected to a vehicle LAN (Local Area Network) 20, for example, as shown in FIG. The control unit 18 is connected to, for example, the vehicle control unit 22 via the vehicle LAN 20, and mutually exchanges information and the like. The vehicle LAN 20 configures a vehicle setting system 2 together with a vehicle setting device 1 and an in-vehicle device as an example. Below, this vehicle setting system 2 is explained.

(Configuration of vehicle setting system 2)
Vehicle configuration system 2, as an example, as shown in FIG. 3, control the vehicle setting device 1, a plurality of in-vehicle devices, a plurality of in-vehicle devices based on the vehicle setting information S ₄ that is output from the vehicle setting device 1 And a vehicle control unit 22 as a control device.

  The vehicle control unit 22 is a microcomputer configured of, for example, a CPU that performs calculation, processing, and the like on acquired data according to a stored program, a RAM that is a semiconductor memory, a ROM, and the like.

As shown in FIG. 3, the vehicle control unit 22 transmits current setting information S ₁₀ to current setting information S ₂₁ , which are information of settings of the steering adjustment device 24 to the video reproduction device 46, to the vehicle at the request of the control unit 18. Acquire via LAN20. The vehicle control unit 22, the acquired current based on the setting information _{S 10} ~ current setting information _{S 21} generates setting information _{S 3,} and outputs to the vehicle setting device 1 via the vehicle LAN 20.

The vehicle control unit 22 acquires the vehicle configuration information _{S 4} from the vehicle-setting device 1 via the vehicle LAN 20. The vehicle control unit 22 generates personalization information S _{30 ~} individual setting information S ₄₁ is information set for each vehicle device based on the vehicle setting information S ₄ obtained, to the corresponding vehicle device via the vehicle LAN20 Output. The in-vehicle apparatus changes the setting registered by the registrant based on the individual setting information corresponding to itself.

  An example of the operation of the vehicle setting device 1 will be described below with reference to the flowchart of FIG.

(Operation)
In the vehicle setting device 1, when the operator carrying the electronic key unlocks the door of the vehicle, the drive voltage is supplied from the vehicle, and the biometric information reading unit 10 is in a state where the fingerprint pattern can be read.

  When the operator operates the start switch 5, the control unit 18 acquires the biological information 100 from the biological information reading unit 10 (Step 1).

  The control unit 18 calculates the similarity between the registered biometric information 140 read from the storage unit 14 and the matching area 185 of the biometric information 100 acquired from the biometric information reading unit 10, and matches the biometric information 100 with the registered biometric information 140.

Control unit 18, the similarity is present identification threshold 180 or more registered biometric information 140, that is, if the operator is a registrant (Step2: Yes), the vehicle identifying identification information _{S 2} the registrant Output to setting table generation unit 16.

Vehicle setting table generation unit 16 generates a vehicle setting information S ₄ the vehicle configuration the registrant has set is read from the vehicle setting table 160, and outputs (Step3). Control unit 18, a vehicle setting information _{S 4} obtained from the vehicle setting table generation unit 16, via the vehicle LAN20 output to the vehicle control unit 22 (Step4). The vehicle control unit 22 generates the individual setting information S ₃₀ to the individual setting information S ₄₁ based on the acquired vehicle setting information S ₄ , and outputs the individual setting information S ₃₀ to the corresponding in-vehicle device to set the in-vehicle device.

  Further, the control unit 18 confirms whether the similarity in the collation area 185 is equal to or more than the update threshold value 181. If the degree of similarity is equal to or higher than the update threshold value 181 (Step 5: Yes), the control unit 18 generates the extended registration area 142 using the non-matching area 102 of the biometric information 100 and expands the extended registration area 142. The registered biometric information 140 is generated (Step 6). The expanded registered biometric information 140 is stored in the storage unit 14.

  Here, in step 2, when the operator is an unregistered person (Step 2: No), the control unit 18 blinks the registration button related to the unregistered registrant and notifies execution of the registration operation ( Step 7).

The control unit 18 stores the biometric information 100 read from the operator, that is, the registrant, as the registered biometric information 140 when the registration operation is performed using the registration readout unit 12 within the set time (Step 8: Yes) While registering in the unit 14, the setting information S ₃ which is information of the current vehicle setting and the identification information S ₂ of the registrant are output to the vehicle setting table generating unit 16. Vehicle setting table generation unit 16 associates the registrant and the vehicle set based on the setting information S ₃ and the identification information S ₂ is stored in the vehicle setting table 160 (Step9), registration operation is completed.

  In step 5, when the degree of similarity is less than the update threshold value 181 (step 5: No), the control unit 18 ends the operation without expanding the registered biometric information 140.

  In addition, in step 8, when the registration operation is not performed within the set time (step 8: No), the control unit 18 ends the operation.

(Effect of the embodiment)
The vehicle setting device 1 according to the present embodiment can generate registered biometric information 140 suitable for collation. Specifically, when the similarity in the collation area 185 is the update threshold value 181 or more, the vehicle setting device 1 does not include the non-collation area 102 which is a portion not included in the registered biometric information 140 of the biometric information 100 to be collated. Since the registered biometric information 140 is expanded in addition to the registered biometric information 140, compared with the case where the registered biometric information used for collation is generated from one biometric information, each time the start switch 5 is operated, As the amount of information increases, registered biometric information 140 suitable for collation can be generated.

  When the similarity in the collation area 185 is the update threshold value 181 or more, the vehicle setting device 1 does not expand the registered biometric information 140 by operating the start switch 5 without the operator being aware of it. As compared with the case, the collation area 185 between the read biometric information 100 and the registered biometric information 140 is enlarged, and the feature points used for collation are increased, and the collation can be performed with higher accuracy.

  In the vehicle setting device 1, since the update threshold 181 is set higher than the identification threshold 180, the possibility that other persons' biological information may be mixed when the registered biological information 140 is expanded is suppressed. Therefore, the vehicle setting device 1 can suppress the extension based on the erroneous biometric information while maintaining the accuracy of the identification of the individual.

  Since the vehicle setting device 1 can perform highly accurate matching, the determination accuracy of the registrant, that is, the recognition rate can be improved, and the vehicle setting suitable for the operator can be provided.

  The vehicle setting device 1 according to the above-described embodiment and modification includes, for example, a part of the program executed by the computer, an application specific integrated circuit (ASIC), a field programmable gate array (FPGA), etc. It may be realized by
