  According to the vehicle function control device of the present invention, it is possible to flexibly cope with a change of a legitimate user of the vehicle, and it is possible to control various functions of the vehicle according to various combinations of passengers.

  The best mode for carrying out the present invention will be described below with reference to the drawings.

  FIG. 1 is a system configuration diagram showing an embodiment of a vehicle function control apparatus according to the present invention. The vehicle function control device 300 according to the present embodiment is configured as a microcomputer including a CPU, a ROM, a RAM, and the like that are connected to each other via a bus (not shown). Various programs executed by the CPU are stored in the ROM.

  Various electronic components in the vehicle are connected to the vehicle function control device 300 via a bus such as a CAN (controller area network). The electronic components are ordinary electronic components mounted on the vehicle, for example, an EFI / ECU 50 for controlling the engine, a brake ECU 52 for controlling the brake device, an air conditioner ECU 54 for controlling the air conditioner, a door lock actuator, a seat actuator, etc. Various electronic control units (ECUs) such as a body ECU 56 that controls the functional components and sensors are included.

  The vehicle function control device 300 includes two series of authentication devices 100 and 200. Specifically, the vehicle function control device 300 performs authentication based on biometric authentication device 100 that performs authentication based on biometric data obtained from a person, and given data that is given in advance to a specific tangible object such as a key. And a key authentication device 200 for performing.

  The biometric authentication device 100 is a biometric data such as a fingerprint or a vein pattern obtained from a human finger, a biometric data such as an iris pattern obtained from a human eyeball, or an image of a captured image of a specific part of a person (for example, a face). It may be based on any biological data such as biological data such as a feature point pattern obtained by processing.

  In the example shown in FIG. 1, a fingerprint sensor 12 for detecting a fingerprint pattern is provided near the door outer handle (not shown) of the vehicle, and the fingerprint sensor 12 is connected to the user when the user opens the door. Detect fingerprint pattern. Further, an in-vehicle camera 14 having an imaging area as a predetermined area in the vehicle interior (in this example, an area where the passengers of each seat are reflected) is disposed at a predetermined position in the vehicle interior. A plurality of in-vehicle cameras 14 may be set so that an occupant of each seat can be detected.

  The biometric authentication device 100 includes an electronic control unit (ECU) 18. The electronic control unit 18 may be a microcomputer including a CPU, various memories, and the like, and various programs executed by the CPU are stored in the memory.

  The electronic control device 18 includes a rewritable storage device 16 such as an EEPROM or a hard disk, and when the biometric data acquired by the biometric data acquisition means such as the above-described fingerprint sensor 12 is collated in the storage device 16. The registered biometric data to be referred to is stored.

  The biometric authentication device 100 performs authentication based on the comparison result between the biometric data acquired by the biometric data acquisition unit such as the fingerprint sensor 12 and the registered biometric data in the storage device 16 (with a specific user and other users). Identify).

  The vehicle function control device 300 switches the predetermined device of the vehicle from the inoperable state to the operable state in accordance with the authentication result (that is, whether or not authentication has been obtained) by the biometric authentication device 100.

  For example, when authentication based on the fingerprint pattern of the fingerprint sensor 12 is obtained by the biometric authentication device 100, the vehicle function control device 300 cooperates with the body ECU 56 when detecting the operation of the door switch (not shown) by the user. The door lock device (door lock actuator) is switched from the unlocked state to the locked state to form a state in which the door can be opened manually by the user.

  In addition, when the biometric authentication device 100 obtains authentication based on the captured image data of the in-vehicle camera 14, the vehicle function control device 300 switches the steering lock from the unlocked state to the locked state in cooperation with the body ECU 56. In this case, the vehicle function control device 300 switches the EFI / ECU 50 (immobilizer function) from the non-movable state to the movable state, and forms a state where engine control can be started, that is, a state where the vehicle can run.

  In the movable state, the EFI / ECU 50 controls engine start according to an operation mode of an engine switch (not shown) by a user (that is, according to an input ignition position signal), an accelerator pedal, etc. Various engine controls are executed according to the operation mode.

  The key authentication device 200 includes a portable device (key) 20 possessed by a user. The portable device 20 has a function of transmitting a predetermined response signal in response to the request signal when receiving the request signal transmitted from the transceiver 30 mounted on the vehicle. This response signal includes a first ID code assigned to the portable device 20 in advance. Hereinafter, bidirectional communication with the vehicle realized by the communication function of the portable device 20 is referred to as “smart communication”.

  The portable device 20 includes a switch 21 that can be operated by the user. The portable device 20 has a function of transmitting a predetermined command signal in response to the operation of the switch 21 by the user. This command signal includes a command for requesting locking or unlocking of the door lock, and similarly includes a second ID code assigned to the portable device 20 in advance. Hereinafter, the one-way communication with respect to the vehicle realized by the communication function of the portable device 20 is referred to as “wireless communication”.

  Key authentication device 200 includes a transceiver 30 mounted on the vehicle side. The transceiver 30 communicates with the portable device 20 outside the vehicle. For example, the transceiver 30a provided outside the vehicle door communicates with the portable device 20 inside the vehicle. And an in-vehicle communication transceiver 30b provided in the panel. A request signal is periodically transmitted from the transceiver 30 toward a predetermined area. The request signal may be transmitted using, for example, 125 to 134 kHz as a use band, and may be given a strength such that the communication distance with the transceiver 30 is about several meters.

  The key authentication device 200 includes an electronic control unit (ECU) 32 mounted on the vehicle. The electronic control device 32 has a function of controlling the various communications in the transceiver 30 and executing key authentication as will be described later. The electronic control device 32 may be a microcomputer including a CPU, various memories, and the like, and predetermined registration data is stored in the memory together with various programs executed by the CPU. The registration data stored in the memory includes registration ID codes corresponding to the first and second ID codes described above.

  The key authentication device 200 performs authentication based on the comparison result between the ID code included in the signal sent from the portable device 20 and the ID code included in the registration data (the specific portable device 20 and other portable devices are Identify).

  Similarly to the authentication result by the biometric authentication device 100, the vehicle function control device 300 can operate the predetermined device of the vehicle from the inoperable state according to the authentication result by the key authentication device 200 (that is, whether or not authentication has been obtained). Switch to state.

  For example, when the verification of the first or second ID code based on the above-described smart communication or wireless communication is obtained by the vehicle communication transmitter / receiver 30a, the vehicle function control device 300 cooperates with the body ECU 56 by the user. The door lock device (door lock actuator) is switched from the unlocked state to the locked state in accordance with the operation mode of the door switch (not shown).

  Further, the vehicle function control device 300 locks the steering lock from the unlocked state in cooperation with the body ECU 56 when the verification of the first ID code based on the above-described smart communication by the in-vehicle communication transceiver 30b is obtained. Switch to state. In this case, the vehicle function control device 300 switches the EFI / ECU 50 (immobilizer function) from the non-movable state to the movable state, and forms a state where engine control can be started, that is, a state where the vehicle can run.

  As described above, in this embodiment, the vehicle function control device 300 uses the complete vehicle function by the user (that is, a legitimate user when the authentication is obtained by one of the two authentication devices 100 and 200). Unconstrained use) for creating possible states. Therefore, for example, a user having registered biometric data in the storage device 16 can freely get into and drive the vehicle without having the portable device 20. That is, since the user having the registered biometric data in the storage device 16 can obtain authentication by the biometric authentication device 100, the user can freely enter and drive the vehicle without obtaining authentication by the key authentication device 200. .

  By the way, in this type of biometric authentication device 100, registration data as a reference source at the time of authentication, that is, registered biometric data in the storage device 16, is set and registered in advance based on data obtained from a legitimate user. It is. However, since this type of setting registration work can be performed only with a predetermined card dealer for security reasons, for example, when there are a plurality of legitimate users such as commercial vehicles and company-owned vehicles and they are likely to fluctuate, This may be inconvenient when a legitimate user changes due to resale of the vehicle.

  On the other hand, in the vehicle function control apparatus 300 according to the present embodiment, as will be described in detail with reference to FIG. 2, the registered biometric data in the storage device 16 is automatically added / registered and deleted appropriately, thereby achieving high security. It is possible to respond flexibly to changes in legitimate users while maintaining the above.

  FIG. 2 is a flowchart showing a main part of processing executed by the vehicle function control device 300 (biometric authentication device 100) of the present embodiment. In the following, it is assumed that the portable device 20 is a regular portable device 20, that is, a portable device 20 whose ID code can be verified by the key authentication device 200.

  First, as step 100, for example, assuming a situation where the user A gets into the vehicle, the biological data acquisition means such as the fingerprint sensor 12 or the in-vehicle camera 14 acquires the biological data related to the user A when getting into the vehicle or thereafter. By doing so, the user A is recognized. Note that the user A is a user who has the portable device 20 as described above or has registered biometric data in the storage device 16 because he / she can get into the vehicle.

  In step 110, the biometric authentication device 100 determines whether or not the number of times the user A has boarded exceeds a predetermined number N in order to evaluate the usage frequency of the user A. The number of times of boarding may be calculated as one time from when the ignition switch is turned on until it is turned off, and may be the number of times of boarding during a predetermined period such as two weeks or two months.

  The number of times of boarding is determined based on the history of biometric data acquired by the biometric data acquisition means for each boarding. For example, the biometric authentication device 100 stores biometric data (biological data other than registered biometric data) acquired by the biometric data acquisition unit for each boarding in the storage device 16 separately from the registered biometric data, and acquired in the past. When the biometric data corresponding to the biometric data is acquired this time, the user's counter value related to the biometric data is incremented by one. This counter is newly set from the counter value 1 when new biometric data is acquired. For a counter related to a user whose counter value does not change continuously for a predetermined period or the predetermined number of boarding times, the counter value may be returned to 1 or may be discarded together with the discarding of the user's biometric data.

  When the number of boarding times (counter value) of the user A is less than the predetermined number N, it is determined that the user A is not a user who uses the vehicle so frequently as to be additionally registered at this stage, and the process proceeds to step 130. In this case, when the user uses the vehicle next time, the user A must carry the portable device 20 or be accompanied by another user who has the registered biometric data in the storage device 16 as in this case.

  On the other hand, when the number of boarding times of the user A exceeds the predetermined number N, the process proceeds to step 120.

  In step 120, the biometric authentication device 100 stores the biometric data related to the user A whose number of boarding times exceeds the predetermined number N in the storage device 16 as registered biometric data. This eliminates the need for the user A to have the portable device 20 when using the vehicle from the next time (that is, registering as a valid user).

  As described above, according to the present embodiment, for a user who uses a vehicle beyond a certain frequency, the biometric data related to the user is stored in the storage device 16 as registered biometric data. The biometric data relating to an appropriate user can be automatically added and registered without going through a manual registration operation such as a dealer. For this reason, according to the present embodiment, even when there are a plurality of legitimate users such as commercial vehicles and company-owned vehicles, and when the legitimate users fluctuate due to resale of vehicles, etc. Since the registered biometric data automatically corresponds to the fluctuation, it is not necessary to force the user to perform registration work corresponding to the user fluctuation.

  Further, in this embodiment, since the counter value for automatic additional registration is increased only when proper use is confirmed, the security is not impaired. That is, the counter value for automatic additional registration is used only for the use of the user who possesses the portable device 20 or the use of a user who is accompanied by a valid user having registered biometric data in the storage device 16. Since it is configured to increase, there is no possibility that an unauthorized counter value is increased by an unauthorized user (an unauthorized automatic additional registration).

  Note that the list information of users including registered biometric data may be displayed on a display, for example, by a predetermined switch operation by a legitimate user. In addition, when it is desired to completely delete the registered user's biometric data by resale or the like, it may be easily deleted by a predetermined switch operation by a truly valid user. In this case, “a truly legitimate user” may be detected and confirmed by using the portable device 20 or detecting the presence of the portable device 20. The presence of the portable device 20 can be detected by collating the first ID code based on smart communication by the above-described in-vehicle communication transceiver 30b.

  When the additional registration process of registered biometric data is executed in step 120 as described above, the process proceeds to step 130.

  In step 130, it is determined whether or not a long-term absent user exists among the registered valid users. This determination is made based on the history of biometric data acquired by the biometric data acquisition means for each boarding, as in step 110 described above. Similarly, for example, when the biometric data acquired by the biometric data acquisition unit is included for each boarding, the biometric authentication device 100 increments the counter value of the user related to the registered biometric data by 1. This counter is newly set from the counter value 1 when new registered biometric data is generated as described above. In this case, the registered biometric data regarding the long-term absent user can be determined based on a counter in which the counter value does not vary for a predetermined period or a predetermined number of boarding times. Alternatively, a user who has passed a predetermined period from the latest boarding time or a user whose boarding is not detected within the latest predetermined number of times may be determined as a long-term absent user.

  In subsequent step 140, the registered biometric data relating to the user determined to be a long-term absent user is deleted from the storage device 16. In other words, the registration is canceled due to the long absence.

  As described above, according to the present embodiment, for registered users who do not use the vehicle beyond a certain frequency, the registered biometric data related to the registered user is deleted from the storage device 16, so that the card dealer The non-registered biometric data relating to the legitimate user whose use frequency has become low can be automatically unregistered without undergoing a manual registration operation. For this reason, according to the present embodiment, even when there are a plurality of legitimate users such as commercial vehicles and company-owned vehicles, and when the legitimate users fluctuate due to resale of vehicles, etc. Since the registered biometric data automatically corresponds to the fluctuation, it is not necessary to force the user to perform registration work corresponding to the user fluctuation.

  The process shown in FIG. 2 may be a process that is executed only once for one boarding (once until the ignition switch is turned on and turned off). However, if there is a change (especially addition of a new occupant) in the passenger compartment during the ride, the above-described processing may be activated and executed on the biometric data related to the user related to the change.

  FIG. 3 is a flowchart illustrating a main part of other processing executed by the vehicle function control device 300 (biometric authentication device 100) according to the present embodiment.

  First, as step 200, for example, assuming a situation where four passengers A, B, C, and D have entered the vehicle, the biological data acquisition means such as the in-vehicle camera 14 is installed on the passenger A, when entering the vehicle or thereafter. The occupants A, B, C, and D are recognized by acquiring the biological data related to B, C, and D. For such recognition, the biometric authentication apparatus 100 stores each biometric data (biometric data other than registered biometric data) acquired by the biometric data acquisition unit for each boarding in the storage device 16 separately from the registered biometric data. Keep it. For example, in the previous example, when the occupant C is the first occupant to board the vehicle this time and there is no biometric data related to the occupant C in the storage device 16, the biometric data related to the occupant C is the biometric data related to the new user. As stored in the storage device 16.

  In this example, since these occupants were able to get into the vehicle, at least one of the occupants A, B, C, D had the portable device 20 or the storage device 16. It is that it was a passenger | crew provided with the registration biometric data.

  In the following step 210, the vehicle function control device 300 changes the EFI • ECU 50 (immobilizer function) from the non-movable state to the movable state as long as any biological data of the occupant existing in the passenger compartment matches the registered biological data. Switch. As a result, even if the only occupant having the registered biometric data in the storage device 16 sits in the passenger seat, the engine can be started by the occupant sitting in another driver seat.

  In the subsequent step 220, the vehicle function control device 300 grasps the combination of the passengers who have entered the vehicle this time based on the recognition result in the step 200 by the biometric authentication device 100. In the previous example, the combination (A, B, C, D) is grasped.

  In subsequent step 230, the vehicle function control device 300 searches the predetermined database 35 (see FIG. 1) for past setting value information relating to the grasped combination. The set value information includes a set value of the first type functional device whose function can be adjusted and set by the operation of the passenger. The first type of functional device is representative of seats, air conditioners, side mirrors, audio devices, etc. that can adjust various settings such as seat position, air conditioning temperature, mirror angle, volume, and mode (DVD mode or CD mode). Take as an example.

  The set value information may further relate to a control parameter of the second type functional device that is automatically set in accordance with the driving mode (癖) of the driver and a favorite learning result. The control parameters of the second type functional device are the shift control of the transmission that automatically switches the shift pattern to suit the driver's intention, and the brake assist amount is automatically set according to the driver (stepping force, brake pedal operation speed) A representative example is a parameter (map) related to brake assist control that can be switched automatically.

  The set value information is acquired by various ECUs and stored in the database 35 for each occupant combination. For example, for the combination (A, B, D), for example, the set value of the air conditioner (setting temperature a1 = 26 degrees, air volume a2 = Medium, air mix door opening a3 = Medium ...), combination (A, D ) Are stored as set values of the air conditioner (set temperature a1 = 24 degrees, air volume a2 = Hi, air mix door opening a3 = MaxCool...). When the set value information relates to a set value that can be changed by a passenger during one boarding, the set value information may be information about a final set value, or information on an average set value. Alternatively, it may be information including the setting history.

  In the following step 240, the vehicle function control device 300 cooperates with various ECUs so as to reproduce the set state corresponding to the set value information corresponding to the current occupant combination. For example, the vehicle function controller 300 issues a command to the air conditioner ECU 54 so that the set value of the air conditioner according to the set value information is obtained, or causes the body ECU 56 to drive the electric motor so that the seat position is set according to the set value information. Give a command. Note that setting values that can vary depending on the season, weather, and time zone, such as air conditioner settings, may be realized by correcting and compensating for these fluctuation factors. Is stored together with environmental information such as season and weather when the information is acquired.

  At this time, if the set value information corresponding to the current occupant combination does not exist in the database 35, for example, in the previous example, the combination (A, B, C, D) is compared with the current occupant combination (A, B, C, D). If there is only set value information related to (B, D) and the combination (A, D), the vehicle function control device 300 does not perform the process of automatically realizing the set value as described above, and goes through step 250. This process may be terminated. Alternatively, in this case, the vehicle function control device 300 may issue various commands based on the set value information regarding the combination (A, B, D) that is partially but most consistent.

  In addition, when a specific user is included in the occupant combination, the vehicle function control device 300 gives priority to the specific user, and therefore, the vehicle function control device 300 performs various operations based on setting value information that best reflects the preference of the specific user. A command may be issued. For example, when the occupant B is a specific user in the previous example, various commands may be issued based on the set value information regarding the combination (A, B, D). The “specific user” may be set and registered in advance in association with the registered biometric data, or the vehicle function control device 300 may determine based on the identification result of the biometric authentication device 100. In the latter case, the vehicle function control device 300 may treat the occupant as a specific user when an elderly person or a baby is identified through image recognition or voice recognition.

  From the same viewpoint, when the occupant who rides for the first time this time is a specific user such as an elderly person or a baby, the vehicle function control device 300 prepares in advance for the specific user without considering any set value information regarding the occupant combination. Special setting values may be realized. For example, in the previous example, when the occupant C is a specific user and there is no set value information related to the combination including the occupant C in the database 35, the vehicle function control device 300 determines that the specific user regardless of the occupant combination. For this purpose, special setting values prepared in advance may be realized.

  Note that the processing of steps 220 to 240 shown in FIG. 3 may be executed only once when the combination of the passengers who have entered the vehicle after the door is opened is recognized. However, when there is a change (especially when a new occupant is added) in the passenger compartment while riding, a change in the setting value reflecting the change in the occupant combination may be executed. In addition, in the process of step 240 shown in FIG. 3, for the set value that is effective to be changed while the vehicle is running, continuously from the time when the ignition switch is turned on until the ignition switch is turned off. It may be changed automatically.

  In step 250, various set values newly acquired by the various ECUs during the one-board period until the ignition switch is turned off (for example, seat position information from the seat position sensor newly acquired by the body ECU 56). Is stored in the database 35 in association with the combination of the passengers who have boarded this time. As a result, when the same combination is used after the next time, various set values similar to those at the time of the previous ride are realized by the above step 240.

  The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the above-described embodiments, and various modifications and substitutions can be made to the above-described embodiments without departing from the scope of the present invention. Can be added.

  For example, in the embodiment shown in FIG. 1, the vehicle function control device 300, the biometric authentication device 100, and the key authentication device 200 are configured by separate hardware, but any two or all of them are the same. It may be embodied in the hardware.
