[0021]
BEST MODE FOR CARRYING OUT THE INVENTION
An embodiment of an identification code distribution system embodying the present invention will be described below with reference to FIGS.
[0022]
FIG. 1 is a schematic configuration diagram of the identification code distribution system 1. The identification code distribution system 1 includes a management server (hereinafter simply referred to as a server) 3 installed in a management center (management company) 2 and a controller 5 mounted on a vehicle 4 as control means. 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).
[0023]
The server 3 stores control software, ID codes (identification codes) of sub IDs, and time stamp data. 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 control, engine control, etc.) by the mobile phone 7. The sub ID is an ID with use restriction registered in the mobile phone 7. The time stamp is the date and time when the sub ID was downloaded to the mobile phone 7. Then, in response to a request from the mobile phone 7, the server 3 causes the mobile phone 7 to download control software, a sub ID, a time stamp, and the like via the public telephone line 6.
[0024]
The vehicle 4 includes an ID key system 8. The ID key system 8 is a system that allows the mobile phone 7 to perform a predetermined operation of the vehicle 4. In the ID key system 8, for example, the door is locked or unlocked or the engine is started by the mobile phone 7. The mobile phone 7 is a wireless telephone using the public telephone line 6. The mobile phone 7 of this example is a mobile phone owned by a person who is not the owner of the vehicle 4, and the owner of the mobile phone 7 is a person who has been permitted to lend the vehicle from the owner of the vehicle 4.
[0025]
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. The microcomputer 9 has a built-in memory 15.
[0026]
When the owner of the vehicle 4 permits the rental of the vehicle, the owner transmits his / her master ID and a password required for connecting to the server to the mobile phone 7 in, for example, a mail format using his / her mobile phone or personal computer. Here, the transmission format of the master ID and the password is not limited to e-mail, but may be any format as long as the information can be communicated, such as verbal notification using a telephone or the like.
[0027]
Then, the master ID and the password are input to the mobile phone 7 as registration IDs (registration identification information), and the mobile phone 7 is connected to the server 3. Then, the server 3 performs personal authentication based on the registration ID, and if the authentication result is correct, sends the control software, the sub ID, and the time stamp data (restriction information (time information)) to the mobile phone 7 via the public telephone line 6. I do. The mobile phone 7 performs setup based on the ID key system program, and downloads the sub ID and time stamp data to the memory 15 after the setup. 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.
[0028]
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.
[0029]
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.
[0030]
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.
[0031]
The microcomputer 19 drives the second communication circuit 20 to cause the antenna 23 to intermittently transmit a response request signal. 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 operates the function command, the encryption ID, and the time stamp corresponding to the operated operation button 12. 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.
[0032]
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 (locking device) to unlock the door lock. . 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.
[0033]
When the microcomputer 19 inputs the encryption ID, the microcomputer 19 calculates a period (use period) from the date of the data to the present based on the time stamp data, and determines whether the use period of the sub ID is within the validity period. Judge. If the use period after downloading the sub-ID to the mobile phone 7 is within the preset expiration date and the master ID and the ID match of the sub-ID match, the microcomputer 19 follows the function command received from the mobile phone 7. Perform various operations.
[0034]
On the other hand, when the use period of the sub ID exceeds the preset expiration date, the microcomputer 19 does not accept the sub ID. For this reason, when the usage period of the sub ID exceeds the expiration date, the mobile phone 7 cannot perform vehicle operations such as door lock (unlock) and engine start.
[0035]
Next, the expiration date processing executed after the distribution of the sub ID will be described with reference to the flowcharts shown in FIGS. First, the server 3 executes the flow shown in FIG. 2 as the expiration date processing.
[0036]
In S100, a registration ID (master ID and password) is received from the mobile phone 7 via the public telephone line 6.
In S101, it is determined whether the registration ID is correct. If the registration ID is correct, the flow shifts to S103, and if not correct, the flow ends.
[0037]
In S102, the ID code of the sub ID and the time stamp data are transmitted to the outside.
Subsequently, at the time of wireless communication between the server 3 and the mobile phone 7, the microcomputer 9 of the mobile phone 7 executes the flow shown in FIG.
[0038]
In step (hereinafter simply referred to as S) 200, the ID code of the sub-ID and the time stamp data are received. That is, the registration ID is transmitted from the mobile phone 7 to the server 3, and if the personal authentication is correct, the mobile phone 7 sets up the system and fetches the sub ID and the time stamp.
[0039]
In S201, an encrypted ID is generated from the sub ID and the master ID.
In S202, when the owner of the mobile phone 7 enters a predetermined area of the vehicle 4 and executes the short-range communication between the mobile phone 7 and the vehicle 4, the encrypted ID and the time stamp data are transmitted. Therefore, the encrypted ID and the time stamp data are transmitted to the vehicle 4 via Bluetooth.
[0040]
Then, at the time of short-range communication between the mobile phone 7 and the vehicle 4, the microcomputer 19 of the vehicle 4 executes the flow shown in FIG.
In S300, the encrypted ID and the time stamp are received from the mobile phone 7. That is, the ID code and the time stamp data of the encrypted ID transmitted from the mobile phone 7 are received via the second communication circuit 20, and the encrypted ID and the time stamp are fetched.
[0041]
In S301, the encrypted ID is decrypted. That is, the encrypted ID is read according to the encryption rule, and the master ID and the sub ID are determined.
In S302, the time stamp of the time stamp is determined. That is, the elapsed time (number of days) from the date of the time stamp to the present is calculated, and the usage period of the sub ID is calculated.
[0042]
In S303, it is determined whether the usage period of the sub ID is within the validity period. Here, if the usage period is within the expiration date, the process proceeds to S304, and if it exceeds the expiration date, the process proceeds to S305.
[0043]
In S304, according to the function command received from the mobile phone 7, the processing of the command is executed. Thereby, the door lock driving device 24 of the vehicle 4 is locked or unlocked, or the engine starting device 25 is operated to start the engine.
[0044]
In S305, the sub ID transmitted from the mobile phone 7 is discarded. That is, if the sub-ID taken from the mobile phone 7 has exceeded the expiration date, the sub-ID is discarded, and the mobile phone 7 cannot execute various functions of the vehicle 4.
[0045]
In this example, when renting the vehicle 4 to another person, the owner of the vehicle 4 gives the registration ID to another person, and accesses the management center 2 with another person's mobile phone 7. Then, if the registration ID is correct, the identification code is downloaded to the mobile phone 7, and the mobile phone 7 can be used as a vehicle key. Therefore, even if the vehicle 4 is lent, even if the sub-ID is downloaded to the mobile phone 7, the mobile phone 7 can be used as a substitute for the vehicle key. There is no need to come.
[0046]
By the way, when the mobile phone 7 whose sub-ID has been downloaded to the mobile phone 7 is used as a vehicle key, if the sub-ID can be used indefinitely, the sub-ID may be misused and lead to vehicle theft. In addition, since the mobile phone 7 is dropped or replaced frequently, it is conceivable that the sub ID is stolen and the vehicle is stolen.
[0047]
However, when the usage period of the sub-ID of the mobile phone 7 exceeds the expiration date, the sub-ID becomes invalid and the vehicle 4 cannot operate. Therefore, even if the sub-ID is registered by another person, the vehicle 4 is not operated by the mobile phone 7 after the expiration date, and the incidence of vehicle theft can be reduced. If the expiration date of the sub-ID has passed, the mobile phone 7 is connected to the management center 2 again, the sub-ID is newly registered in the mobile phone 7, and the mobile phone 7 is used as a vehicle key. .
[0048]
Therefore, the following effects can be obtained in the first embodiment.
(1) When renting the vehicle 4 to another person, the renter is informed of the registration ID, and the borrower inputs the registration ID to the mobile phone 7 and accesses the server 3. Then, by downloading the sub-ID to the mobile phone 7, the mobile phone 7 can be used as a substitute for the vehicle key, so that it is not necessary to go out to borrow the vehicle key when renting the vehicle 4. In particular, if the owner of the key is away from the vehicle 4, it is necessary to go there to rent the vehicle 4, but here, the sub-ID is downloaded to the mobile phone 7 and used as a substitute for the key. There is no hassle to get the key.
[0049]
(2) An expiration date is set for the sub-ID downloaded to the mobile phone 7. Therefore, even if a sub-ID is registered in another person's mobile phone 7, if the expiration date is exceeded, the sub-ID becomes invalid, so that the probability that the sub-ID is misused and the vehicle 4 is stolen can be reduced.
[0050]
(3) For example, the ID code of the sub-ID itself can be used as the ID for limitation, but in this case, the microcomputer 19 on the vehicle 4 side performs a load-intensive process. However, based on the time stamp sent from the server 3, the microcomputer 19 determines whether or not the usage period of the sub-ID is an expiration date, so that only a relatively simple program needs to be used.
[0051]
The embodiment is not limited to the above, and may be changed as follows, for example.
Various operations of the vehicle 4 such as door lock / unlock and engine start are not limited to being operated by pressing the operation button 12 of the mobile phone 7; for example, a smart key system may be employed. That is, when a user (driver) carrying the mobile phone 7 approaches the vehicle 4, the door lock is automatically unlocked, and when the user moves away, the door is automatically locked or when the ignition knob is turned without operating the key, the engine is turned on. May be started.
[0052]
-The registration ID is not limited to being composed of the master ID and the password. For example, only the master ID or the password may be used. The registration ID is not particularly limited as long as the master ID can be derived.
[0053]
The owner of the vehicle 4 registers the password in the server 3, and the sub-ID is downloaded to the mobile phone 7 accessed using the password within a predetermined time (for example, 1 to 5 hours) after the registration. You may.
[0054]
When permitting the vehicle 4 to be rented, the master ID and the password are not limited to being provided in the form of e-mail, and these numbers may be provided orally, for example, through a telephone port.
[0055]
When receiving the registration ID, the server 3 is not limited to downloading the sub ID only to the mobile phone 7. For example, the server 3 may download the sub-IDs to both the mobile phone and the vehicle 4 and perform short-range communication between the mobile phone 7 and the vehicle 4 based on these codes.
[0056]
The use restriction of the vehicle 4 is not limited to the expiration date of the sub-ID. For example, only the locking / unlocking of the door lock may be permitted and other functions may not be used. If the expiration date is exceeded, the door lock control can be performed with the sub ID, but a restriction that the engine cannot be started may be imposed.
[0057]
In the case where the sub-ID has an expiration date, it is not limited to determining whether the sub-ID has passed the expiration date using the time stamp. For example, the sub ID itself may be used as an ID for the expiration date, and the microcomputer 19 of the vehicle 4 may calculate the use period when the sub ID is input, and may not operate the vehicle 4 if the use period exceeds the expiration date.
[0058]
-The mobile terminal is not limited to the mobile phone 7. For example, the mobile terminal may be a personal computer or the like capable of communicating with the server 3, and is not particularly limited as long as the sub ID can be transmitted via wireless communication.
[0059]
The various functions performed by the vehicle 4 by the short-range communication using the Bluetooth of the mobile phone 7 are not limited to door lock or unlock, engine start, and the like, and the functions are not particularly limited as long as the vehicle 4 is operated. .
[0060]
The first wireless communication network is not limited to the public telephone line 6, and for example, a dedicated line network may be used. Further, the second wireless communication network is not limited to Bluetooth, and another wireless communication method such as IrDA may be used.
[0061]
The control target of the mobile phone 7 is not limited to the vehicle 4 and may be, for example, a door of a house entrance. That is, the entrance door or the like may be locked or unlocked by the sub ID downloaded to the mobile phone 7. When the vehicle 4 is to be controlled, the vehicle 4 is not limited to an automobile, but may be, for example, a motorcycle or an industrial vehicle, and the type of the vehicle is not particularly limited.
[0062]
