  In addition, the vehicle setting device 1 generates a vehicle setting table 160 that associates a setting of each of a plurality of in-vehicle devices mounted on the vehicle when receiving the registration operation with a registrant who has performed the registration operation. It has sixteen.

  In this vehicle setting device 1, as an example, after the door is unlocked by authentication based on wireless communication with an electronic key or the like, a drive voltage is supplied from the battery of the vehicle, and acquisition of the biological information 100 by the biological information reading unit 10 It can be done. The vehicle setting device 1 may be configured not to unlock the door by authentication based on wireless communication, but to supply the drive voltage when the door is unlocked by the physical key or when the door is opened.

(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.

  The start switch 5 is disposed, for example, on the front of an operator seated in the driver's seat or on a floor console located between the driver's seat and the front passenger seat, and is configured as a push switch. 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 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.

  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)
The registration reading unit 12 has a plurality of switches for receiving a registration operation, and priorities are assigned to the plurality of switches. Specifically, as an example, as shown in FIG. 1 (b), 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. ing. 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. .

Air conditioner 40, navigation device 42, music reproduction device 44, video reproduction device 46, and the like. 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.

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 the above lighting or blinking. good.

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.

  In the present embodiment, each registration button has a priority such that the priority is given in the order of registration button 123 (low priority) <registration button 122 (high priority) <registration button 121 (high priority). Assigned to The assignment of the priority is that the registration button located on the upper side is easier to register as the psychology of the operator on the sheet of FIG. 1B, and the registration button prints “A” to “C”. If it is, it is easy to register from the first letter of the alphabet, "A". If a number is printed on the registration button, the smaller the number, the easier it is to register, so the priority is assigned high.

  As a modification, for example, the registration button 121 to the registration button 123 may be configured to light up or blink so that the operator can recognize the priority.

  As another modification, for example, by operating a plurality of registration buttons, the vehicle setting device 1 registers and reads the vehicle settings of more than three registrants according to the combination of the pressed registration buttons. It may be configured to be able to

(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. The ROM stores, for example, a program for the control unit 18 to operate, an identification threshold 180, and range information 181. 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 greater than the threshold 180, it is determined that the operator is a registrant.

  The feature points are, for example, four points called center point, branch point, end point and triangle. The central point is a point that is the center of the fingerprint pattern. A branch point is a point at which ridges of a fingerprint branch. An end point is a point where a ridge is broken. A triangle 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.

  Here, when there is registered biometric information 140 having a degree of similarity within a predetermined range from the maximum value of the degree of similarity, control unit 18 according to the present embodiment further registers registered biometric information 140 having a high priority. It is determined that the registrant who registered the is an operator. The predetermined range is stored in the control unit 18 as range information 181, for example.

When the predetermined range is 20, for example, the control unit 18 confirms a registrant having a similarity of 60 or more because the maximum value of the similarity is 80. In the case of the above-mentioned example, the registrant whose similarity is 60 or more is registrant C. The control unit 18 confirms the priority between the registrant A having the highest similarity and the registrant C having the similarity within a predetermined range based on the vehicle setting table 160, and the priority of the registrant A because who is higher than the priority of the registrant C, and generates the identification information S ₂ to a registrant a the operator. The control unit 18 outputs, for example, the identification information S ₂ to the vehicle setting table generation unit 16, to output the vehicle settings registrant A as vehicle setting information S _4.

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 of the present embodiment will be described below according 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 turns on the start switch 5, the biometric information reading unit 10 reads a fingerprint pattern, generates biometric information 100, and outputs the biometric information 100 to the control unit 18 (Step 1).

  When acquiring the biological information 100, the control unit 18 reads out the registered biological information 140 from the storage unit 14 and calculates the degree of similarity (Step 2).

(Effect of the first embodiment)
The vehicle setting device 1 according to the present embodiment can improve the determination accuracy even if there are a plurality of candidates having high similarity.

  Specifically, the vehicle setting device 1 registers a high priority even if there are a plurality of registered biometric information 140 having a high degree of similarity with the biometric information 100 of the operator due to variations in the acquired biometric information 100 or the like. The registrant having the biometric information 140 is determined to be an operator. This high priority registrant is most likely to be a frequent registrant. In other words, this registrant is most likely to get on the vehicle compared to other operators. Therefore, the vehicle setting device 1 registers the registered biometric information 140 having the highest priority among the registered biometric information 140 even if there is a plurality of registered biometric information 140 having a high degree of similarity with the biometric information 100 of the operator. Since the registrant is determined to be the operator, it is possible to improve the overall recognition rate including the prior probability as compared with the case of determination based only on the similarity. The prior probability is the probability whether the registrant A gets on or the registrant B gets on.

Since the size of the registration button increases in the order of the registration button 123 (low priority), the registration button 122 (during priority), and the registration button 121 (high priority), the registrant selects the registration button 121 and the registration button. It is easy to press the registration button in the order of 122 and the registration button 123.

  Moreover, as a modification regarding the assignment of the priority, in the vehicle setting device 1, the registration button 121 to the registration button 123 are disposed on the instrument panel 90 of the vehicle 9, as shown in FIG. 5 (b). In the case of this modification, since the operator sitting on the driver's seat is disposed on the instrument panel 90 located in front, the registration button is disposed such that the registration button 121 to the registration button 123 are directed from the top to the bottom It is done. Accordingly, since the registrant can be easily pressed from top to bottom, the priority is set to be high in the order of the registration button 121 to the registration button 123, that is, in the order of the registrant A to the registrant C.

  As another modification, the vehicle setting device 1 may be configured to be able to register only in the order of the registration button 121 to the registration button 123. That is, the registrant can not register the vehicle setting by pressing the registrant C, that is, the registration button 123 although the registrant B is not set, for example. The priority is increased in the order of the registration button 123 (priority low), the registration button 122 (medium priority), and the registration button 121 (priority high) as in the above-described example.

  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
