[0019]
BEST MODE FOR CARRYING OUT THE INVENTION
(1st Embodiment)
Hereinafter, a first embodiment of an identification code registration / update system embodying the present invention will be described with reference to FIGS.
[0020]
FIG. 1 is a schematic configuration diagram of the identification code registration / update system 1. The identification code registration / update system 1 includes a management server (hereinafter, referred to as a server) 3 installed in a management center (management company) 2 and a controller 5 as a control device mounted on a vehicle 4. The server 3 can communicate with the outside via a public telephone line 6 as a public line network, and here exchanges various data with a mobile phone 7 as a mobile terminal. Further, the controller 5 can communicate with the mobile phone 7 via Bluetooth (R).
[0021]
The server 3 stores control software and ID codes (identification codes) of sub-IDs. The control software is a program for setting up a program for the ID key system in the mobile phone 7 and a program for controlling the vehicle (door lock / unlock, engine start, etc.) by the mobile phone 7. The sub ID is an ID registered in the mobile phone 7 instead of the master ID of the master key. Then, in response to a request from the mobile phone 7, the server 3 causes the mobile phone 7 to download control software and a sub ID via the public telephone line 6.
[0022]
The vehicle 4 has an ID key system, and the ID key system 8 is a system that enables the mobile phone 7 to perform a predetermined operation of the vehicle 4. In the ID key system 8, for example, the door of the vehicle 4 is locked or unlocked and the engine is started by the mobile phone 7. The mobile phone 7 is a wireless telephone using the public telephone line 6, and is used here instead of a master key.
[0023]
The mobile phone 7 includes a microcomputer 9, a transmission / reception circuit 10, a display screen 11, and operation buttons 12, which are mutually connected via a bus 13. The microcomputer 9 performs processing for making the mobile phone 7 function as a telephone, and executes various operations based on, for example, display control of the display screen 11 and input of the operation buttons 12. The transmission / reception circuit 10 modulates a transmission signal transmitted from the antenna 14 and demodulates a reception signal of a radio wave received from the outside via the antenna 14.
[0024]
The microcomputer 9 has a built-in memory 15. The control software downloaded from the server 3 is stored in the memory 15. As a control software download procedure, the user (telephone owner) operates the operation button 12 of the mobile phone 7 to connect the mobile phone 7 to the management center 2 (server 3). Then, based on an instruction from the server 3, control software is downloaded to the memory 15 via the public telephone line 6.
[0025]
After the control software is downloaded to the mobile phone 7, the user operates the operation button 12 of the mobile phone 7 to input a master ID (registered identification information) and connects the mobile phone 7 to the server 3. At this time, if the ID check is correct, the server 3 causes the mobile phone 7 to execute system setup. When the mobile phone 7 is set up, the server 3 causes the ID code of the sub-ID to be downloaded to the memory 15 of the mobile phone 7 via the public telephone line 6. When the mobile phone 7 receives the sub ID, the microcomputer 9 generates an encrypted ID by combining the master ID and the sub ID.
[0026]
When the mobile phone 7 is set up, various operation functions are assigned to the operation buttons 12 of the mobile phone 7. As this assignment, for example, "1" of the operation button 12 is set as a button for locking or unlocking the door, and "2" is set as a button for engine start. When the operation buttons 12 are operated in this state, a function command corresponding to the function of each button is transmitted from the mobile phone 7 to the outside via Bluetooth.
[0027]
The mobile phone 7 includes a first communication circuit 16 as a short-range communication unit including a Bluetooth chip. The first communication circuit 16 exchanges a wireless signal with the vehicle 4 by the short-range communication. The first communication circuit 16 has a built-in wireless circuit 17 and an antenna 18 which are modularized. The wireless circuit 17 converts a wireless signal received from the outside via the antenna 18 so that the microcomputer 9 can read the signal, and transmits a wireless signal to the outside via the antenna 18 in response to a command from the microcomputer 9.
[0028]
The controller 5 of the vehicle 4 includes a microcomputer 19 and a second communication circuit 20. The microcomputer 19 has a built-in memory 21, and the memory 21 stores ID codes of a master ID and a sub ID. The second communication circuit 20 forms a pair with the first communication circuit 16 of the mobile phone 7 and can communicate with the first communication circuit 16 of the mobile phone 7. The second communication circuit 20 has a circuit configuration substantially the same as that of the first communication circuit 16, is formed of a one-chip IC, and has a built-in modularized radio circuit 22 and antenna 23.
[0029]
The microcomputer 19 drives the second communication circuit 20 to cause the antenna 23 to intermittently transmit a response request signal. Then, when the operation button 12 is pressed while the mobile phone 7 receives the response request signal (the state where the link is established), the microcomputer 9 puts the function command and the encryption ID corresponding to the operated operation button 12. A response signal is transmitted from the first communication circuit 16 to the vehicle 4. The second communication circuit 20 receives the response signal via the antenna 23, and the microcomputer 19 compares the ID code from the mobile phone 7 with the ID code in the memory 21 to execute code collation.
[0030]
When the code matches, the microcomputer 19 executes various functions according to the function command transmitted from the mobile phone 7. For example, when “1” of the operation buttons 12 is pressed in a state where the door lock is locked, the microcomputer 19 drives the door lock driving device 24 as a driving device to unlock the door. On the other hand, if "1" of the operation button 12 is pressed in a state where the door lock is unlocked, the door lock is locked. When the driver presses "2" of the operation button 12 while sitting in the driver's seat, the microcomputer 19 drives the engine starting device 25 as a driving device to execute fuel injection and engine ignition to start the engine. Start.
[0031]
Further, the identification code registration / update system 1 has a function of updating the sub-ID of the mobile phone 7. More specifically, first, the mobile phone 7 is connected to the server 3 and a new sub ID is downloaded to the mobile phone 7. After the new sub-ID is registered, when the operation button 12 of the mobile phone 7 is operated in a state where the link with the vehicle 4 is established, the function command and the encryption ID corresponding to the operated operation button 12 are operated. Is transmitted from the mobile phone 7. Then, the microcomputer 19 receives the response signal transmitted by Bluetooth via the antenna 23.
[0032]
The microcomputer 19 decrypts the encrypted ID (master ID and sub-ID) and checks the code of the ID code. When both the master ID and the sub ID match the ID code of the memory 21, the microcomputer 19 determines that the sub ID of the mobile phone 7 has not been updated and does not update the sub ID. Then, the microcomputer 19 operates various functions (door lock or unlock, engine start, etc.) according to a function command corresponding to the operation button 12 operated by the user.
[0033]
On the other hand, when the ID code of the master ID matches but the ID code of the sub ID does not match, the microcomputer 19 determines that the sub ID of the mobile phone 7 has been updated, and changes the ID code according to the encryption rule (encryption rule). After reading, the sub ID of the memory 21 is rewritten and updated to a new ID code. If the master ID is different or violates the encryption rule at the time of reading the ID code, the microcomputer 19 determines that another person's mobile phone not combined with the controller 5 of the vehicle 4 has been used and does not operate various functions.
[0034]
Next, an operation flow executed when the sub ID is updated will be described with reference to the flowchart shown in FIG.
First, in step (hereinafter simply referred to as S) 100, the mobile phone 7 is connected to the server 3 (the management center 2).
[0035]
In S101, control software is downloaded to the mobile phone 7 based on an instruction (voice, mail, or the like) from the server 3.
In S102, the user operates the operation button 12 to input the master ID into the mobile phone 7, and sets up the mobile phone 7 so that the mobile phone 7 can download the sub ID.
[0036]
In S103, the sub ID is downloaded from the server 3. Thereby, the ID code of the sub ID is registered in the memory 15 of the mobile phone 7. Also, S104 to S108 described below are processes executed at the time of short-range communication by Bluetooth between the vehicle 4 (controller 5) and the mobile phone 7.
[0037]
In S104, the encrypted master ID, sub-ID, and function command are transferred to the vehicle 4 by the short-range communication of the mobile phone 7. That is, when the operation button 12 of the mobile phone 7 is pressed in a state where the link between the vehicle 4 and the mobile phone 7 is established, a response signal carrying the function command corresponding to the operation button 12 and the encrypted ID is transmitted to the mobile phone 7. Transferred from telephone 7.
[0038]
In S105, the encrypted ID is decrypted, and the code collation between the master ID and the sub ID is executed.
In S106, it is determined whether or not the ID codes of the master ID and the sub ID received from the mobile phone 7 match the ID codes registered in the memory 21. If the code matches, the process proceeds to S107, and if not, the process proceeds to S108.
[0039]
In S107, various functions are operated according to the function commands of the mobile phone 7. That is, for example, the door is locked or unlocked when the operation button 12 of the mobile phone 7 is pressed, or the engine is started when the operation button 12 is pressed.
[0040]
In S108, the sub ID of the memory 21 is updated according to the encryption rule. That is, the ID code of the sub ID transmitted from the mobile phone 7 is read according to the encryption rule, and the sub ID is stored in the memory 21. Thereafter, the updated sub-ID is used for code collation between the vehicle 4 and the mobile phone 7. When the update procedure is executed in accordance with the encryption rule, the sub ID is not updated if the rule is violated.
[0041]
By the way, in order to use the mobile phone 7 as a substitute for the vehicle key, a sub-ID is registered in the mobile phone 7 and used as an ID code transmission source. However, if one sub ID is used for a long period of time, the sub ID is stolen, and the probability of vehicle theft increases. Further, the use cycle of the mobile phone 7 is shorter than that of the vehicle 4, and the mobile phone 7 may be discarded with replacement. In this case, it is conceivable that the sub-ID may be stolen from the discarded mobile phone 7, and some measures have to be taken from the viewpoint of security.
[0042]
However, in this example, each time the mobile phone 7 is set up, a new sub-ID is registered in the mobile phone 7, and when the mobile phone 7 and the vehicle 4 perform short-range communication, the sub-ID of the mobile phone 7 is changed to the vehicle 4 And the sub ID is updated. Therefore, the sub-ID of the mobile phone 7 is regularly updated, and it is difficult for the vehicle to be stolen due to the sub-ID being stolen, and the security against the vehicle theft is ensured.
[0043]
Therefore, the following effects can be obtained in the first embodiment.
(1) The mobile phone 7 is connected to the management center 2 to acquire a sub-ID, and the sub-ID is registered in the controller 5 of the vehicle 4 by Bluetooth short-range communication, so that the sub-ID between the vehicle 4 and the mobile phone 7 is The ID is updated. For example, a burglar steals a sub-ID from the mobile phone 7 and attempts to steal the vehicle 4 using the sub-ID. However, if the sub ID is updated, the stolen sub ID becomes a past ID, and the vehicle 4 cannot be operated even if the sub ID is used at the time of the theft. Therefore, it is not necessary for the stolen person to execute various functions such as the door lock and the engine start of the vehicle 4, and the security against theft of the vehicle 4 can be improved.
[0044]
(2) The door lock operation and the engine start of the vehicle 4 are executed by the short-range communication with the mobile phone 7, and the identification code of the sub-ID is put on the radio signal transmitted from the mobile phone 7 at the time of the short-range communication. By transmitting the information to the vehicle 4, the sub-ID of the vehicle 4 is updated. Therefore, it is not necessary to perform a new operation when registering the sub ID in the vehicle 4.
[0045]
(3) Whenever the mobile phone 7 is connected to the management center 2, the sub-ID is registered in the mobile phone 7 each time. Therefore, the user can register the sub-ID in the mobile phone 7 at his / her desired free time. Can be.
[0046]
(4) The master ID and the sub ID are encrypted and transmitted from the mobile phone 7, and the microcomputer 19 reads these IDs according to the encryption rule. Then, when the encryption rule is violated, the sub ID is not updated, so that an illegal sub ID is not accepted, and the security against theft of the vehicle can be further improved. Also, when reading the ID, the master ID is also watched, and the sub ID is updated only when the master ID is correct, so that security can be improved.
[0047]
(2nd Embodiment)
Next, a second embodiment will be described with reference to FIG. Since this embodiment has the same basic configuration as the first embodiment, the same parts are denoted by the same reference numerals, detailed description thereof will be omitted, and only different parts will be described.

Keyless entry function. Also, the smart key system 31 has an ignition function in which if the ID verification is correct, the engine can be started by turning the ignition knob 32 without inserting the ignition key into the engine start cylinder.
[0049]
The microcomputer 19 of the vehicle 4 drives the second communication circuit 20 to cause the antenna 23 to intermittently transmit a response request signal. When the first communication circuit 16 of the mobile phone 7 receives the response request signal, the microcomputer 9 transmits a response signal carrying the encrypted ID (master ID and sub ID) from the first communication circuit 16 to the vehicle 4. Let it. The second communication circuit 20 receives the response signal via the antenna 23, and the microcomputer 19 compares the ID code from the mobile phone 7 with the ID code in the memory 21 to execute code collation.
[0050]
If the codes match, the microcomputer 19 drives the door lock driving device 24 to unlock the door lock. Therefore, if the driver owns the mobile phone 7, the door can be automatically unlocked. When the code matches, the microcomputer 19 drives the engine starting device 25 to make the engine start permitted. Therefore, the driver can start the engine simply by operating the ignition knob 32 without performing any key operation. Further, when the owner of the mobile phone 7 moves out of the predetermined area and the antenna 23 stops receiving the response signal, the door lock is locked.
[0051]
Further, the identification code registration / update system 1 has a function of updating the sub-ID of the mobile phone 7. More specifically, first, the mobile phone 7 is connected to the server 3 and a new sub ID is downloaded to the mobile phone 7. When a link with the vehicle 4 is established after the registration of the new sub ID, the microcomputer 19 takes in the encrypted ID, decrypts the encrypted ID, and checks the ID code.
[0052]
If the ID code of the master ID matches but the ID code of the sub ID does not match, the microcomputer 19 determines that the sub ID of the mobile phone 7 has been updated. The microcomputer 19 reads the ID code according to the encryption rule, rewrites the sub ID in the memory 21, and updates the sub ID with a new ID code. If the master ID is different or the encryption rule is violated when reading the ID code, the microcomputer 19 determines that another person's mobile phone that is not combined with the controller 5 of the vehicle 4 has been used and does not operate various functions.
[0053]
Therefore, in the second embodiment, the same effects as (1) to (4) described in the first embodiment can be obtained, and the following effects can be obtained.
(5) Even in a configuration in which the mobile phone 7 has the same function as the smart key, the code of the mobile phone 7 and the sub-ID of the vehicle 4 can be updated. When the mobile phone 7 approaches the vehicle 4 by the smart key system 31, the sub-ID of the vehicle 4 is automatically updated, so that an extra operation for updating the code is not required.
