Description

  The present invention relates to a vehicle electronic key system that controls the locking / unlocking state of a locking device and the setting of a facility device by wireless communication between the vehicle and a portable device.

  2. Description of the Related Art Conventionally, techniques for controlling various locking devices of a vehicle via an authentication system using wireless communication have been developed. For example, wireless communication between a vehicle and a portable device owned by the user of the vehicle confirms a person around the vehicle, and automatically activates the door lock device when an authorized user is approaching the vehicle. An electronic key system that unlocks automatically is known. Such an authentication system is applied not only to locking and unlocking a door lock device, but also to controlling locking and unlocking of a start switch of an engine or a traveling motor.

  In this type of electronic key system, based on authentication information transmitted from the portable device to the vehicle side, it is determined whether or not the person who owns the portable device is an authorized user. To give a specific example, unique ID information preset for each portable device is transmitted to the vehicle side, and it is determined whether the ID information is correct on the vehicle side, and the user who owns the portable device Is authenticated.

  In recent years, a personal authentication system using personal user ID information instead of portable device ID information has also been proposed. That is, authentication is performed using the privacy information of the individual user carrying the portable device. For example, it has been proposed to perform personal authentication based on the user's driver's license number or credit card number, or to perform personal authentication using the user's fingerprint, palm print, voice print, iris, or the like.

  Furthermore, when an individual driver is identified, it is proposed to control not only the door lock device, engine, and driving motor, but also on-board equipment such as indoor and outdoor mirror devices, seat position adjustment devices, and handle position adjustment devices. Has been. By such control, it is considered that not only the lock management of the vehicle but also the driving environment according to the preference of each user can be provided (for example, see Patent Documents 1 and 2).

  However, in the vehicle electronic key system to which the personal authentication system as described above is applied, the personal information of the user is converted into electronic data and stored in a portable device or an electronic control device of the vehicle. Therefore, there is a risk that the personal information may be leaked, copied, or tampered by unauthorized access such as skimming the portable device or hacking the electronic control device. Therefore, in order to ensure the reliability of the personal authentication system, there is a problem that information security measures for the portable device and the electronic control device of the vehicle must be strengthened.

  Moreover, the personal authentication system as described above has a problem that it is difficult to deal with an unspecified number of users. For example, when multiple users are authenticated for a shared vehicle managed by a family, small company, condominium community, etc., privacy information corresponding to all users is prepared in advance on the personal authentication system side. I have to keep it. For this reason, the procedure for adding and changing users becomes complicated, and the convenience of car sharing may be impaired.

  A hatched area in FIG. 2 is a transmission / reception range of signals by the respective antennas 45 to 47. When wireless communication between the in-vehicle control device 4 and the KOS key 1 is established, the relative position of the KOS key 1 with respect to the vehicle 10 is grasped based on the positions of the antennas 45 to 48 that have received signals from the KOS key 1. The Alternatively, the relative position of the KOS key 1 with respect to the vehicle 10 is grasped based on the reception intensity of the signal from the KOS key 1 received by each antenna 45 to 48.

[1-2. KOS key]
The KOS key 1 has an FOB 2 (portable device, electronic key) and a mechanical key 3 inserted therein. The FOB 2 is a key case type wireless transmission / reception apparatus that accommodates wireless communication devices. The wireless communication device is enclosed in a resin housing formed in an oval shape, for example. Moreover, the mechanical key 3 is a mechanical key (emergency key) for switching the locking / unlocking states of the doors 17 to 19 by manual operation, and is accommodated in the FOB 2 so that it can be inserted and removed.

  As shown in FIG. 3, an insertion port 21 (insertion portion) into which the mechanical key 3 is inserted is formed at one end side of the FOB 2. On the surface of the FOB 2, a lock button 22, a lock release button 23, and a rear gate button 24 for remotely operating the lock states of the doors 17 to 19 are provided. Furthermore, a shape sensor 25 (detection unit) for detecting the shape of the mechanical key 3 inserted in the FOB 2 is built in the FOB 2, and a portable device control device 20 and an antenna 29 for wireless communication are built in the FOB 2. .

  The portable device control device 20 is an electronic control device that controls the wireless transmission / reception function of the FOB 2. The portable device control device 20 receives the operation input to the buttons 22 to 24, the detection result of the shape sensor 25, the signal received by the antenna 29, and the like, and the signal transmitted from the antenna 29 is output. The The portable device control device 20 operates by receiving power supply from a button battery (not shown) built in the FOB 2.

  As shown in FIGS. 4 (A) to (C), the mechanical key 3 has an engagement portion 3a formed with a key pattern for switching the locking and unlocking states of the doors 17 to 19 by manual operation. An uneven portion 3b formed in a shape corresponding to the user of the vehicle 10 is provided. A key pattern corresponding to the lock structure of the lock incorporated in the doors 17 to 19 is formed on the engaging portion 3a. The key pattern has a shape unique to each vehicle 10. When there are a plurality of users of one vehicle 10, the key patterns of the mechanical keys 3 provided to the respective users are the same. Hereinafter, the information regarding the shape of the key pattern of the mechanical key 3 is referred to as “key pattern information”.

  On the other hand, the concavo-convex portion 3b is a portion where a concavo-convex shape for determining the user of the vehicle 10 (the person holding the mechanical key 3) is formed. 4A to 4C illustrate the uneven portion 3b provided with a plurality of cuts in order to visually express that the shape of the part corresponds to specific information. In this example, the concavo-convex portion 3b is cut into a comb shape, and the shape of each part partitioned (segmented) by adjacent cuts is used as information for determining the user of the vehicle 10. .

For example, as shown in FIG. 4 (A), for each of the three leaf pieces 3c divided by four cuts, the non-absent part means a binary number "0". Think. Further, the missing part is considered to mean a binary number “1”. That is, one piece of information is given to one leaf piece 3c.
Then, the concavo-convex pattern of the concavo-convex portion 3b shown in FIG. 4A can be regarded as expressing a binary number “000”, that is, can be converted into 3-bit information. Similarly, the concavo-convex pattern of the concavo-convex portion 3b shown in FIG. 4B can be converted into a binary number “001”, and the concavo-convex pattern of the concavo-convex portion 3b shown in FIG. 4C is converted into a binary number “101”. Can be converted.

  If these binary information and the user of the vehicle 10 are associated with each other, the user of the vehicle 10 can be determined based on the uneven pattern of the uneven portion 3b. As described above, the uneven shape of the uneven portion 3b is the shape of the uneven pattern obtained by converting binary information for identifying the user of the vehicle 10 into an array of the missing portion and the not-missed portion. It is said. Hereinafter, binary information corresponding to the shape of the concavo-convex pattern of the concavo-convex portion 3b is referred to as “concave / convex pattern information”.

  The shape sensor 25 detects the shape of the engaging portion 3a (key pattern shape) of the mechanical key 3 and the shape of the concavo-convex portion 3b (shape of the concavo-convex pattern), and the above-mentioned “key pattern information” and “concave / convex pattern information”. Is a sensing device that acquires " These pieces of information are transmitted to the portable device control device 20.

  In the example shown in FIGS. 4A to 4C, whether the part means “1” or “0” depending on whether or not the leaf piece 3 c of the concavo-convex part 3 b is missing. ", That is, the shape of the leaf piece 3c is binarized. On the other hand, if the shape of the leaf piece portion 3c is lacking in multiple stages and different numerical values are assigned for each shape, the shape of the leaf piece portion 3c can be multi-valued. In this case, the recording density of the concavo-convex pattern information in the concavo-convex portion 3b increases as the degree of multi-leveling is increased (for example, the concavo-convex pattern is converted into ternary or quaternary). The degree of multi-leveling may be determined according to the resolution and detection accuracy of the shape sensor 25 that detects the uneven shape of the mechanical key 3.

Specific examples of the nonvolatile memory 54 include a flash memory, a phase change memory (Phase Change Memory), a resistance change memory (Resistive RAM), a ferroelectric memory (Ferroelectric RAM), and a magnetoresistive memory (Magnetoresistive RAM). The control contents in the FOB 2 are recorded in the ROM 52 or the nonvolatile memory 54 as an application program, for example. When the program is executed, the contents of the program are expanded in the memory space in the RAM 53 and the nonvolatile memory 54 and executed by the microprocessor 51.

[2-2. In-vehicle control device]
The vehicle-mounted control device 4 (control device) of the vehicle 10 is an electronic control device that comprehensively controls body-related electrical components. For example, as with the portable device control device 20, a microprocessor 55, a ROM 56, a RAM 57, and a nonvolatile memory. 58 is an electronic device in which 58 and the like are integrated. This in-vehicle control device 4 is connected to a communication line of an in-vehicle network provided in the vehicle 10. Various known electronic control devices such as an engine control device, a brake control device, a transmission control device, a vehicle stability control device, and an air conditioning control device are communicably connected to each other on the in-vehicle network.

  The in-vehicle control device 4 receives a radio signal received by the right antenna 45, the left antenna 46, the rear antenna 47, and the indoor antenna 48 and a touch operation signal output from the door switch 9. When the frequency of the wireless communication signal is different between transmission and reception, a plurality of antennas 45 to 48 (reception antenna and transmission antenna) corresponding to each frequency band may be provided.

When the program is executed, the contents of the program are expanded in the memory space in the RAM 57 and the nonvolatile memory 58 and executed by the microprocessor 55.

[2-3. System functions]
The main functions provided by the in-vehicle control device 4 are listed below.
Function 1. 1. Function function for permitting a regular passenger to lock and unlock the door lock device 5. 2. Immobilizer function function that allows a normal occupant to start the engine 16 Boarding environment customization function that automatically changes the setting of the equipment to the setting according to the preference of each occupant with locking and unlocking

Regarding the above function 1, locking and unlocking operations of the door lock device 5 are permitted in the following cases, for example.
-When the FOB2 buttons 22-24 are operated-When the KOS key 1 exists near the door and the door switch 9 is operated

  Regarding the above function 2, the starting operation of the engine 16 is permitted when the engine 16 is started and when the regular KOS key 1 is present in the passenger compartment. For example, when the start switch of the engine 16 (not shown) is operated and the wireless communication is established with the regular KOS key 1 via the indoor antenna 48, the start control of the engine 16 is started. Alternatively, the start control of the engine 16 may be started by operating the start switch of the engine 16 while holding the regular KOS key 1 over a predetermined position.

  Whether the KOS key 1 is genuine or not is confirmed by checking the identification number (key ID) unique to each KOS key 1 (for example, comparing the key ID of the KOS key 1 with the vehicle ID number of the vehicle 10). Can be determined. Thus, the function of permitting or prohibiting the start of the engine 16 by comparing the key ID (key identification number) of the KOS key 1 with the vehicle ID number of the vehicle 10 is referred to as an immobilizer function. Since the regular KOS key 1 is possessed only by a regular user, only the authorized user is allowed to start the engine 16 by the immobilizer function.

  Regarding the above function 3, when the driver's seat door 17 or the passenger seat door 18 is unlocked, the setting of the equipment is changed to a setting corresponding to the user who performed the unlocking operation. Further, when the driver's seat door 17 and the passenger seat door 18 are locked after all passengers get off, the settings corresponding to the previous user are returned to the standard settings before the change. Such a setting change is performed only for an authorized user. Hereinafter, a control configuration for mainly realizing the function 3 will be described in detail.

[2-4. Control on KOS key side]
As shown in FIG. 5, when the processing contents in the FOB 2 are functionally classified, the application program executed in the FOB 2 is provided with a data storage unit 26, a collation unit 27, and a transmission unit 28.

  The data storage unit 26 (storage unit) stores the correspondence between the key pattern information of the mechanical key 3 and the uneven pattern information detected by the shape sensor 25 and the vehicle ID number of the vehicle 10. Here, the vehicle ID number of the vehicle 10 is used to identify each vehicle 10 as in the case of a chassis number (frame number), a vehicle number (number plate number), and a vehicle identification number (VIN, Vehicle Identification Number). Which is unique to each vehicle 10. However, in order to prevent information leakage due to skimming, theft, or loss of the FOB 2, it is preferable to assign a unique number different from the chassis number or the vehicle number.

Whether the mechanical key 3 inserted into the KOS key 1 is authorized or not is determined in two steps based on both the key pattern information and the uneven pattern information. Here, two types of tables recorded in the data storage unit 26 are illustrated in FIGS. 6 (A) and 6 (B).
FIG. 6A is a key pattern table in which the correspondence between key pattern information and vehicle ID numbers is defined. Each key pattern information is information unique to each vehicle 10 and is set not to overlap with the vehicle 10 having another vehicle ID number. Since the key pattern for each vehicle 10 does not change unless the locking device of the vehicle 10 is replaced, the key pattern table is stored in the ROM 52 where information cannot be rewritten in consideration of data integrity. It is preferable to keep it.

  When the KOS key 1 is used only for one vehicle 10, at least the relationship between the vehicle ID number of the vehicle 10 and the corresponding key pattern information may be recorded in the data storage unit 26. As long as there is one vehicle 10 to be controlled, the correspondence between the vehicle ID number of the vehicle 10 and the key pattern information even if there are a plurality of regular occupants (drivers, users) of the vehicle 10 There should be only one relationship.

  On the other hand, the FOB 2 of the present embodiment can be used for general purposes such as inserting different mechanical keys 3 and using one FOB 2 for a plurality of vehicles 10. For example, in a home, community, company, car sharing system, or the like that owns a plurality of vehicles, a plurality of vehicles 10 and a driver are assumed, so the correspondence between the vehicle 10 and the driver is not uniquely determined. Therefore, in the FOB 2 of the present embodiment, as shown in FIG. 6A, the correspondence relationship between the vehicle ID numbers of a plurality of vehicles 10 and the respective key pattern information is stored.

  FIG. 6B is a concavo-convex pattern table in which the correspondence between the concavo-convex pattern information and the vehicle ID number is defined. The uneven pattern information is information corresponding to the shape of the uneven portion 3 b of the mechanical key 3 and is not necessarily unique to each vehicle 10. That is, there can be a plurality of uneven pattern information corresponding to one vehicle ID number. The number of concavo-convex pattern information corresponding to one vehicle ID number is made to match the number of regular occupants who drive the vehicle 10 having the vehicle ID number. For example, when one vehicle 10 is shared by three people, each driver is given a mechanical key 3 having a different concavo-convex pattern, and one vehicle is included in the concavo-convex pattern information of the mechanical key 3 possessed by each driver. What is necessary is just to make it respond | correspond to ID number.

  Further, there can be a plurality of vehicle ID numbers corresponding to one uneven pattern information. The number of vehicle ID numbers corresponding to one concavo-convex pattern information is matched with the number of vehicles 10 driven by a regular driver who possesses the mechanical key 3 of the concavo-convex pattern. For example, when driving three vehicles 10 alone, a total of three mechanical keys 3 corresponding to each vehicle 10 are given to the driver, and for each of the three vehicle ID numbers. One uneven pattern information may be associated. When the KOS key 1 is used only for one vehicle 10, the relationship between at least the vehicle ID number of the vehicle 10 and the uneven pattern information corresponding thereto is recorded in the data storage unit 26. Good.

  The concavo-convex pattern table may be recorded in the ROM 52 where information cannot be rewritten, or may be recorded in the nonvolatile memory 54 where information can be rewritten. If it is recorded in the nonvolatile memory 54, it becomes easy to add a new mechanical key 3 for the vehicle 10. On the other hand, when the number of drivers of the vehicle 10 does not change (for example, when it is known that only three drivers drive), it is recorded in the ROM 52 in consideration of data integrity. Just keep it.

  The collating unit 27 uses the data table stored in the data storage unit 26 and the “key pattern information” and “concave / convex pattern information” input from the shape sensor 25, and the mechanical key 3 inserted into the FOB 2 is authentic. It is what collates. First, the collation part 27 searches the vehicle ID number of the vehicle 10 corresponding to the key pattern information of the mechanical key 3 from a data table as shown, for example in FIG. 6 (A).

  Here, when the key pattern information is correct, at least the vehicle ID number of the vehicle 10 corresponding to the key pattern information exists in the data table in the data storage unit 26. Therefore, when the vehicle ID number of the vehicle 10 corresponding to the key pattern information is found, the collating unit 27 indicates that “the mechanical key 3 is authorized (the authorized mechanical key 3 is inserted in the FOB 2)”. judge. On the other hand, when the vehicle ID number of the vehicle 10 corresponding to the “key pattern information” is not found, the collation unit 27 indicates that “the mechanical key 3 is not authorized (the authorized mechanical key 3 is not inserted in the FOB 2)”. Is determined.

  Moreover, the collation part 27 searches the vehicle ID number of the vehicle 10 corresponding to the uneven | corrugated pattern information of the mechanical key 3 from a data table as shown, for example in FIG.6 (B). A plurality of vehicle ID numbers corresponding to the uneven pattern information may correspond. After that, the vehicle ID number corresponding to the key pattern information and the vehicle ID number corresponding to the uneven pattern information are collated, and when the former vehicle ID number is included in the latter vehicle ID number, It is determined that the information is “validated (information for changing the boarding environment of the vehicle 10 is given)”. On the other hand, when the latter vehicle ID number does not include the former vehicle ID number, or when the mechanical key 3 is not inserted into the FOB 2, the “boarding environment customization function is not activated (the boarding environment of the vehicle 10 is changed). No information for changing is given). The determination result here is transmitted to the transmission unit 28.

  The transmission unit 28 (output unit), when the predetermined locking / unlocking condition is satisfied under the condition that the collating unit 27 determines that “the mechanical key 3 is genuine”, the doors 17 to 19 A signal for switching the lock / unlock state (first signal, lock request, unlock request) is output. The predetermined locking / unlocking conditions include operation of the FOB 2 buttons 22 to 24, reception of a confirmation signal from the in-vehicle control device 4, and the like. This “confirmation signal” is a signal transmitted from the in-vehicle control device 4 to the KOS key 1 when the door switch 9 of the vehicle 10 is operated, and has the KOS key 1 in the vicinity of the vehicle 10. It is a signal for confirming that a person exists.

  For example, when the lock button 22 is operated in a state where the regular mechanical key 3 is inserted into the FOB 2, the transmission unit 28 transmits a lock request and key pattern information to the in-vehicle control device 4. When the unlock button 23 is operated in a state where the regular mechanical key 3 is inserted into the FOB 2, the transmitting unit 28 transmits an unlock request and key pattern information to the in-vehicle control device 4. On the vehicle 10 side, the locking / unlocking state of the door lock device 5 is controlled in response to these locking requests and unlocking requests. Note that when the lock release button 23 is operated, the unlock request and the key pattern information are not transmitted unless the regular mechanical key 3 is inserted into the FOB 2.

  In addition, when the unlocking request is transmitted from the transmitting unit 28, if it is determined by the collating unit 27 to “enable the boarding environment customization function”, the setting for changing the boarding environment of the vehicle 10 The change request and the uneven pattern information are transmitted from the transmission unit 28 together with the unlock request. In other words, the transmission unit 28 is configured to change the boarding environment of the vehicle 10 when the collating unit 27 determines that “information for changing the boarding environment of the vehicle 10 is given”. A signal (second signal, uneven pattern information) is output. On the other hand, when the collation unit 27 determines that “the boarding environment customization function is not validated”, such a setting change request and uneven pattern information are not transmitted.

[2-5. Vehicle side control]
As shown in FIG. 5, when the processing contents in the in-vehicle control device 4 are functionally classified, the application program executed in the in-vehicle control device 4 includes a data storage unit 41, a collation unit 42, a transmission unit 43, and a control. A portion 44 is provided.

  The data storage unit 41 (storage unit) stores two types of correspondences. The first correspondence is the correspondence between the key pattern information transmitted from the KOS key 1 side and the vehicle ID number of the host vehicle. That is, in the data storage unit 41, at least the correspondence relationship of the part related to the host vehicle is recorded in the key pattern table stored in the FOB2. Note that the same table as the key pattern table stored in the FOB 2 may be stored in the data storage unit 41. Hereinafter, the table in which the correspondence relationship between the key pattern information and the vehicle ID number of the host vehicle is defined is referred to as “own vehicle key pattern table”.

  The second correspondence relationship stores the correspondence relationship between the uneven pattern information transmitted from the KOS key 1 side and the setting of the equipment device. The setting of the equipment is set according to the preference of the user who possesses the mechanical key 3 on which the uneven pattern is formed. That is, the user who possesses the mechanical key 3 can change arbitrarily while boarding the vehicle 10.

  FIG. 6C shows an example of the equipment device setting table. In this setting table, the correspondence between the uneven pattern information and the setting of the equipment is defined. The number of concavo-convex pattern information recorded in this setting table is a number corresponding to the number of types of concavo-convex portions 3b formed on the mechanical key 3 (that is, the number of types of concavo-convex pattern information). For example, as shown in FIGS. 4A to 4C, when the concavo-convex portion 3b has 3-bit information, the maximum number of records (maximum value of the number of table rows) recorded here is also 3 bits (8 Type).

  Further, on the concave / convex pattern table recorded on the FOB 2 side, the number of concave / convex pattern information corresponding to the vehicle ID number of the vehicle 10 corresponds to the number of records (number of table rows) on the setting table. For example, on the concavo-convex pattern table shown in FIG. 6B, when the concavo-convex pattern information corresponding to “vehicle 1” is three from “0” to “2”, the number of records on the setting table is also three. Then, the setting of the equipment corresponding to each uneven pattern information of “0” to “2” is determined.

  It should be noted that, on the concave / convex pattern table recorded on the FOB 2 side, the concave / convex pattern information record that does not correspond to the vehicle ID number of the vehicle 10 does not include the mechanical key 3 having the concave / convex pattern information or the mechanical key 3 does not exist. This indicates that the user who has the key 3 has not set anything. That is, when a new mechanical key 3 having uneven pattern information is prepared and the user who possesses the mechanical key 3 newly registers the setting of the equipment device, the contents are reflected in the setting table.

  The setting content of the equipment device corresponds to the equipment device connected to the in-vehicle control device 4. In FIG. 6C, the seat position (distance from the reference position) adjusted by the seat adjustment device 6, the steering tilt angle (angle difference from the reference direction with respect to the elevation direction) adjusted by the handle adjustment device 7, the mirror The angle of the rearview mirror 14 adjusted by the adjusting device 8 (angle difference from the reference direction with respect to each of the orthogonal X and Y directions) is set.

  Other equipment settings include the reaction force setting of the pedal (accelerator pedal, brake pedal), the correspondence relationship of the control amount to the pedal depression amount, the shift timing setting of the automatic transmission, the illuminance setting of the lighting device, the vehicle The standard temperature setting of the indoor air conditioner, the volume / sound quality / balance setting of the acoustic device, the vehicle operation mode setting (for example, sports mode, eco mode) and the like can be mentioned. The setting of the equipment device can be appropriately changed according to the user's preference. Therefore, it is preferable to store the setting table of the equipment device in the nonvolatile memory 58 capable of rewriting information.

  The collation unit 42 collates the table recorded in the data storage unit 41 with the key pattern information and the uneven pattern information transmitted from the FOB 2 to determine the suitability of the received radio signal. The key pattern information is used to determine whether the lock request and the unlock request transmitted from the FOB 2 side together with the key pattern information are regular requests. The uneven pattern information is used for setting the equipment.

  First, the collation unit 42 collates the own vehicle key pattern table with the key pattern information when receiving the lock request or the unlock request. When the key pattern information exists on the own vehicle key pattern table, it is determined that the request transmitted together with the key pattern information is a legitimate request. On the other hand, when there is no key pattern information on the own vehicle key pattern table, it is determined that the request is not a regular request. The determination result here is transmitted to the control unit 44.

  Moreover, the collation part 42 collates the setting of an installation apparatus based on the uneven | corrugated pattern information, when the setting change request and uneven | corrugated pattern information from the FOB2 side are received. Here, the setting corresponding to the received concavo-convex pattern information is read from the setting table recorded in the data storage unit 41.

  When a legitimate user of the vehicle 10 gets on the vehicle 10 for the first time, there may be no setting on the setting table corresponding to the received uneven pattern information. On the other hand, when the user newly registers the setting of the equipment device, the contents are reflected in the setting table, so that the setting corresponding to the received uneven pattern information is read out at the next boarding. Information relating to the settings read here is transmitted to the control unit 44.

  The transmitter 43 transmits a confirmation signal to the KOS key 1 when the door switch 9 of the vehicle 10 is operated. The direction in which the confirmation signal is transmitted is a direction corresponding to the operated door switch 9. For example, when the door switch 9 of the driver's seat door 17 is touch-operated, a confirmation signal is transmitted toward the right side of the vehicle 10. When the door switch 9 of the rear gate 19 is touch-operated, the confirmation signal is sent to the rear of the vehicle 10. A confirmation signal is sent to the destination.

  The control unit 44 controls the locking / unlocking state of the door lock device 5 and the setting state of the equipment device based on a signal transmitted from the FOB 2 side. The lock / unlock state of the door lock device 5 is switched to either the locked state or the unlocked state when a lock request / unlock request that is recognized as a proper one is transmitted from the FOB 2 side.

  Further, the control unit 44 changes the setting state of the equipment device simultaneously with the unlocking of the door lock device 5. The changed setting is a setting read from the setting table by the collation unit 42 and is a setting corresponding to the received uneven pattern information. That is, when the door lock device 5 is unlocked, the setting of the equipment device is changed to a setting corresponding to the user who owns the FOB 2 that unlocks the door lock device 5. Furthermore, the control part 44 implements the control which returns the setting of the changed installation apparatus when the door lock apparatus 5 is locked after all the passengers get off. For example, when all the doors 17 to 19 of the vehicle 10 are locked with the engine 16 stopped, the setting of the equipment device is returned to the standard setting.

  In addition, you may decide to implement control which returns the setting of the changed equipment apparatus to the original, when uneven | corrugated pattern information is not transmitted from the FOB2 side at the time of unlocking the door lock apparatus 5. FIG. In addition, when there is no setting corresponding to the concave / convex pattern information transmitted from the FOB 2 side when the door lock device 5 is unlocked, the same control may be performed or a new setting corresponding to another setting may be performed. Until such uneven pattern information is received, the control configuration may be such that the setting of the changed equipment is maintained.

[3. flowchart]
7 and 8 exemplify the control procedure executed by the portable device control device 20 of the FOB 2, and FIGS. 9 and 10 show the control procedure executed by the in-vehicle control device 4 of the vehicle 10. This is just an example. The flow of FIG. 7 corresponds to the control content related to the setting of the control flag, and the flow of FIG. 8 corresponds to the control content related to the transmission of the unlocking request. Moreover, the flow of FIG. 9 respond | corresponds to the control content regarding the unlocking of the door lock apparatus 5, and the setting of an installation apparatus, and the flow of FIG. 10 respond | corresponds to the control content regarding the setting change of an installation apparatus. These flows are repeatedly executed at a preset control cycle.

[3-1. Flag setting]
The unlocking flag F ₁ in the flow of FIG. 7 is a flag mechanical key 3 represents whether or not regular. When the mechanical key 3 is regular, F ₁ = 1, and when the mechanical key 3 is not regular, F ₁ = 0. The uneven flag F ₂ is a flag indicating whether or not the setting of the equipment according to the preference of the user who possesses the mechanical key 3 is registered. When F ₂ = 1, the boarding environment customization function is enabled, and when F ₂ = 0, the function is disabled.

In step A10, it is determined whether or not the mechanical key 3 has been inserted into the insertion port 21 of the FOB 2. When the mechanical key 3 is not inserted, the process proceeds to step A90, and both the unlock flag F ₁ and the uneven flag F ₂ are set to 0. On the other hand, when the mechanical key 3 is inserted, the process proceeds to Step A20.

  In step A <b> 20, the key pattern of the mechanical key 3 inserted into the FOB 2 is detected by the shape sensor 25, and the key pattern information is transmitted to the portable device control device 20. In step A30, the collating unit 27 collates the key pattern information of the mechanical key 3 with the key pattern table. Here, if the key pattern information of the mechanical key 3 does not exist on the key pattern table, the mechanical key 3 is not the mechanical key 3 (mechanical key 3 of the vehicle 10) that can control the unlocked state by the FOB 2. Proceed to A90. On the other hand, if the key pattern information of the mechanical key 3 exists on the key pattern table, the process proceeds to step A40, and the vehicle ID number corresponding to the key pattern information is stored as “the vehicle ID number of the key-compatible vehicle”.

In subsequent step A50, the uneven pattern of the mechanical key 3 is detected by the shape sensor 25, and the uneven pattern information is transmitted to the portable device control device 20. In step A60, the collating unit 27 collates the concave / convex pattern information of the mechanical key 3 with the concave / convex pattern table. Here, when the “vehicle ID number of the key-compatible vehicle” is included in the vehicle ID number corresponding to the uneven pattern information, it is determined that the vehicle corresponding to the uneven pattern matches the key-compatible vehicle. Then, the process proceeds to Step A70. In this case, both the unlock flag F ₁ and the uneven flag F ₂ are set to 1.

In Step A60, if the “vehicle ID number of the key-corresponding vehicle” is not included in the vehicle ID number corresponding to the uneven pattern information, the process proceeds to Step A80. For example, when the mechanical key 3 on which the concave / convex pattern is formed is used for the first time, the key pattern of the mechanical key 3 is correct and only the concave / convex pattern cannot be confirmed, so the process proceeds to Step A80. In Step A80, the unlock flag F ₁ is set to 1 and the uneven flag F ₂ is set to 0.

[3-2. Send unlock request]
The flow of FIG. 8 will be described. In Step B10, it is determined whether or not the unlocking button 23 of the FOB 2 has been operated in the transmission unit 28 of the portable device control device 20, and if not operated, the process proceeds to Step B20. Proceed to B30.

  Moreover, in step B20, it is determined whether the confirmation signal from the vehicle 10 side has been received. This confirmation signal is a signal transmitted from the in-vehicle control device 4 toward the KOS key 1 when the door switch 9 of the vehicle 10 is operated, for example. When the confirmation signal is received, the process proceeds to step B30. When the confirmation signal is not received, the control of this flow in this control cycle is ended. In these steps B10 and B20, conditions for permitting the unlocking operation of the door lock device 5 are determined.

In step B30, the value of the unlocking flag F ₁ is determined whether or not F ₁ = 1, the flow proceeds to step B40 during establishment of this condition, unlocking request and key pattern information to the vehicle control device 4 Sent. On the other hand, when this condition is not satisfied, the control of this flow in this control cycle ends. Therefore, even if the lock release button 23 is operated in a state where the mechanical key 3 is not inserted into the FOB 2, the unlock request is not transmitted.

In the subsequent step B50, it is determined whether or not the value of the uneven flag F ₂ is F ₂ = 1. When this condition is satisfied, the process proceeds to step B60, and the setting change request and the uneven pattern information are transmitted to the in-vehicle control device 4. On the other hand, when this condition is not satisfied, the control of this flow in this control cycle ends. Therefore, in the state where the mechanical key 3 on which the uneven pattern not formed on the uneven pattern table is inserted is inserted into the FOB 2, only the unlocking operation and the key pattern information are transmitted, and the setting change request and the uneven pattern information are not transmitted.

[3-3. Unlock, set, change settings]
The flow of FIG. 9 will be described. In Step C10, it is determined whether or not the door switch 9 provided on the doors 17 to 19 of the vehicle 10 has been operated. Here, when the door switch 9 is operated, the process proceeds to step C 20, and a confirmation signal is transmitted from the transmission unit 43 to the KOS key 1. On the other hand, when the door switch 9 is not operated, step C20 is skipped and the process proceeds to step C30.

  In step C30, the collation unit 42 of the in-vehicle control device 4 determines whether or not an unlock request from the KOS key 1 side has been received. Here, when the unlock request has not been received, the control of this flow in this control cycle ends. On the other hand, if an unlock request has been received, the process proceeds to step C40.

  In step C40, the collation unit 42 collates the key pattern information received together with the unlock request with the own vehicle key pattern table, and determines whether or not the key pattern information is authorized. If the key pattern information is correct, the process proceeds to step C50, where the door lock device 5 is unlocked. On the other hand, when the key pattern information is not genuine, the locked state of the door lock device 5 is maintained, and the control of this flow in this control cycle is completed. The door lock device 5 that is unlocked in step C50 is at least the door lock device 5 for the door on the one side that has received the unlock request.

  In subsequent step C60, the collation unit 42 determines whether or not a setting change request from the KOS key 1 side has been received. If no setting change request has been received, the control of this flow in this control cycle ends. On the other hand, if a setting change request has been received, the process proceeds to step C70.

  In Step C70, the collation unit 42 collates the uneven pattern information received together with the setting change request with the setting table recorded in the data storage unit 41, and reads the setting of the equipment device corresponding to the uneven pattern information. Thereafter, in step C80, a control signal is output from the control unit 44 to the equipment device, and the setting of the equipment device is set to correspond to the received uneven pattern information. That is, the user who has the mechanical key 3 on which the uneven pattern corresponding to the received uneven pattern information is formed is recognized by the in-vehicle control device 4, and the setting of the equipment device is changed to a setting according to the user's preference. .

  In step C90, it is determined whether or not the setting change of the equipment device is completed, and the control of step C80 is repeated until the setting change is completed. When the setting change is completed, the process proceeds to step C100, a predetermined answer back process is performed, and the control of this flow is finished. Note that the specific answer back processing is arbitrary, and for example, it is possible to emit a notification sound from an in-vehicle speaker device or blink a blinker device.

  FIG. 10 is a flowchart exemplifying control contents for a user who is on board the vehicle 10 to newly register (or overwrite update) the setting regarding the setting of the equipment device. This flow is repeatedly performed at a predetermined cycle when the in-vehicle control device 4 receives the uneven pattern information, for example.

  In step D10, it is determined in the vehicle-mounted control apparatus 4 whether the setting of the installation apparatus was changed. Here, when the setting has not been changed, the control of this flow in this control cycle ends. On the other hand, if the setting has been changed, the process proceeds to step D20.

  In step D20, the changed setting contents are overwritten and saved in the setting table of the data storage unit 41. The record updated at this time is a record corresponding to the uneven pattern information received in advance. In the subsequent step D30, a control signal for updating the contents of the concavo-convex pattern table recorded in the data storage unit 26 of the portable device control device 20 is transmitted to the KOS key 1.

  For example, when an authorized user who has an authorized mechanical key 3 sets up the equipment for the first time, the uneven pattern information of the mechanical key 3 and the vehicle ID number of the vehicle 10 are transmitted to the KOS key 1 side. Then, the concavo-convex pattern table of the data storage unit 26 is updated. Therefore, at the next boarding, the setting change request and the uneven pattern information are transmitted from the KOS key 1 to the vehicle 10, and the setting of the equipment device is changed in conjunction with the unlocking operation of the door lock device 5. Will be.

[4. Action, effect]
(1) As described above, in the above electronic key system, the user who holds the mechanical key 3 is grasped based on the shape of the concavo-convex portion 3b formed on the mechanical key 3, and the vehicle 10 corresponding to the user is identified. Both setting and locking / unlocking state are controlled. Therefore, it is possible to easily provide the boarding environment according to the user's preference while appropriately performing the locking / unlocking management of the vehicle 10, and the convenience can be improved.
Compared to conventional locking systems that use biometric personal authentication, it is easier to handle a large number of unspecified users, and there is no need to maintain and manage personal authentication information, improving the reliability of locking management. Can be made.

  Further, since the shape of the concave and convex portion 3b of the mechanical key 3 does not include privacy information or biometric information related to the individual user, even if the FOB 2 or the mechanical key 3 is lost, information about the user is leaked. There is no fear. That is, it is possible to suppress the outflow of information related to the user and improve the safety and reliability of the authentication system. Alternatively, even if skimming to the KOS key 1 is performed, the outflow of information about the user can be suppressed, and the safety and reliability of the authentication system can be improved.

  (2) In the above electronic key system, two types of tables (key pattern table and concave / convex pattern table) are stored in the data storage unit 26 of the FOB 2, and it is confirmed that the key pattern and the concave / convex pattern are individually correct. In addition, it is confirmed that the vehicle ID information corresponding to the key pattern matches the vehicle ID information corresponding to the concave / convex pattern. In this way, by confirming the relationship between the key pattern and the concavo-convex pattern, for example, even when the locking / unlocking state of a plurality of vehicles 10 is controlled by one KOS key 1, the door lock device 5 It is possible to prevent erroneous unlocking and erroneous setting of equipment. Therefore, the convenience of the vehicle 10 can be improved and the reliability of the authentication system can be improved.

  (3) In the above electronic key system, for example, as shown in FIGS. 4A to 4C, the shape of the concave and convex portion 3 b of the mechanical key 3 is binary information corresponding to the user of the vehicle 10. The concave-convex shape is converted into an arrangement of a missing part and a non-missing part. Thus, by converting binary information into a concavo-convex shape, a large amount of information can be recorded reliably in a narrow space. In addition, by converting information corresponding to the user into simple figures (for example, semicircular shapes, star shapes, cross-shaped geometrical and symbolic shapes), the correspondence between the uneven pattern shape and the user The relationship can be made difficult for outsiders to understand, and the reliability of the authentication system can be improved.

  (4) Also, as shown in FIGS. 4A to 4C, if the concave and convex portion 3b is formed as a resin or metal portion cut into a comb shape, the user of the vehicle 10 can mechanically The uneven pattern information of the key 3 can be set and changed arbitrarily. In this case, it becomes difficult for anyone other than the user of the vehicle 10 to know the correspondence between the uneven pattern shape and the user, and the reliability of the authentication system can be improved.

[5. Modified example]
Regardless of the embodiment described above, various modifications can be made without departing from the spirit of the invention. Each structure of this embodiment can be selected as needed, or may be combined appropriately.

  In the above embodiment, the example in which the KOS key 1 itself determines whether or not the mechanical key 3 inserted into the KOS key 1 is authentic is exemplified. It is good also as a control structure to implement. That is, the key pattern table and the concave / convex pattern table may be stored in the data storage unit 41 of the in-vehicle control device 4 and the suitability of the key pattern and the concave / convex pattern may be determined on the vehicle 10 side. In this case, in addition to the effects of the above-described embodiment, the configuration of the portable device control device 20 can be simplified, and the manufacturing cost of the KOS key 1 can be reduced.

  On the other hand, when the portable device control device 20 determines whether the key pattern and the concave / convex pattern are appropriate, the unlocking request and the setting change request by the unauthorized mechanical key 3 are not transmitted from the KOS key 1 side. The reliability of the system can be improved. Further, as in the above-described embodiment, the suitability of the mechanical key 3 is determined twice by judging the suitability of the key pattern and the uneven pattern on both the portable device control device 20 side and the vehicle 10 side. Thus, the reliability of the authentication system can be further improved.

  In the above-described embodiment, it is assumed that one KOS key 1 is used for a plurality of vehicles 10 and that there are a plurality of users for one vehicle 10. The electronic key system can be applied to other forms of usage. For example, even if the user of the vehicle 10 is the same, there are cases where it is desired to use different settings of a plurality of equipment devices. In this case, if a plurality of mechanical keys 3 having different shapes of the concavo-convex portions 3b are prepared, the user can easily select a desired setting by using the mechanical keys 3 properly.
