(General Configuration of a Vehicle Control System 1)
As shown in
The vehicle control device 80 is mounted on the vehicle 8. The vehicle 8 is sold in different grades with different prices. Plural electronic devices are also mounted on the vehicle 8. As an example, the highest grade vehicle 8 is in a state in which functions with high added-value among executable functions of the plural electronic devices are available, i.e., can be used as the allowed functions (90) in addition to the standard functions. On the other hand, as an example, the lowest grade vehicle 8 is in a state in which only the standard functions among executable functions of the plural electronic devices can be used, i.e., mainly the functions with high added-value are the disallowed functions (91). In this way, for the vehicle 8, all electronic devices are mounted rather than installing different electronic devices depending on the grade, and available functions, i.e., the allowed functions (90) are different with different grades.
The vehicle control device 80 is mounted on the vehicle 8 that is rented for a fee or shared, the vehicle 8 used as so-called rental car or car sharing. For the vehicle 8, the allowed functions (90) and the disallowed functions (91) are set according to, e.g., a rental fee. That is, when the rental fee is high, functions with high added-value are set as the allowed functions (90). Meanwhile, when the rental fee is low, the standard functions are set as the allowed functions (90).
Furthermore, the vehicle 8 is also used as a vehicle that is shared by family members and provides different available functions for each family member. In this vehicle 8, e.g., functions selected according to preferences of family members are set as the allowed functions (90) and a terminal 6 of each family member stores the selected functions as the function information 5.

(Configuration of the Software 3)
The software 3 is a program that activates and deactivates functions of electronic devices mounted on the vehicle 8, i.e., manages the allowed functions 90 and the disallowed functions 91. The software 3 in the present embodiment is mainly used to change the disallowed functions 91 to the allowed functions 90, but it is not limited thereto and it is also used to change the allowed functions 90, which have been used up to the present, to the disallowed functions 91.
The change from the allowed functions 90 to the disallowed functions 91 is carried out, e.g., when the allowed functions 90 have an expiration date, when the existing allowed functions 90 become unnecessary due to new allowed functions 90, or when the allowed functions 90 are deprecated, etc.
As an example, the general outline of the method for changing the disallowed function 91 to the allowed function 90 is as follows. For example, a user operates the terminal 6 to connect to the server 2 through the network 4 and purchases the software 3 to change the disallowed function 91 to the allowed function 90. Next, the user starts up the software 3 downloaded from the server 2. The function information 5 is created, e.g., after the software 3 is started up. The function information 5 includes information about the allowed function 90 and the disallowed function 91.
When the vehicle 8 is rented for a fee, e.g., the fee for renting the vehicle 8 is included in the purchase price of the software 3. Which allowed functions 90 are available depends on the amount of the rental fee.
(Configuration of the Network 4)

That is, the terminal 6 serves as an electronic key of the vehicle 8. At this time, the terminal 6 communicates with the vehicle control device 80, and when the terminal 6 is a device registered to the vehicle 8, the terminal 6 serves as an electronic key. This authentication is successfully completed when, e.g., information of the terminal 6 included in the function information 5 matches information registered to the vehicle 8.
When the vehicle 8 is rented out, the user to whom it is rented can use the terminal 6 as an electronic key by downloading and starting up the software 3 on his/her terminal 6 and changing the disallowed function 91 related to the electronic key to the allowed function 90.

Next, an operation of the vehicle control system 1 in the present embodiment will be described in reference to each drawing. An example of when the user adds the biometric authentication function to the start switch 82 will be described below. The general outline of the method in this case is as below. In this regard, the biometric information is a fingerprint in the present embodiment, but is not limited thereto and may be another biometric information such as vein. In the vehicle control system 1, when the vehicle 8 has. e.g., a face authentication function, a function of accepting an operation on the start switch 82 upon successful face authentication may be the allowed function 90.
The terminal 6 has, based on the software 3 obtained from the server 2, functions of generating the function information 5 and reading and transmitting user's biometric information as registered biometric information to the start switch 82 through the vehicle control device 80. The vehicle control device 80 changes the biometric authentication function pre-installed on the start switch 82 from the disallowed function 91 to the allowed function based on the function information 5 obtained from the terminal 6. The start switch 82 performs biometric authentication by comparing the biometric information, which is read with the biometric authentication function when an operation is performed, to the registered biometric information registered through the terminal 6. Then, when the biometric authentication is successfully completed, the start switch 82 outputs a signal to start, or prepare to start, the drive device.
(Operation)
The user operates the terminal 6 and connects it to the server 2 (Step 1). Next, after connecting to the server 2, the user selects the fingerprint authentication function to purchase and then purchases the software 3 to add the fingerprint authentication function (Step 2).
When a touch operation is performed on the icon 60c showing “Yes”, the server 2 transmits the software 3 selected for purchase to the terminal 6 (Step 3).
The terminal 6 downloads the software 3 from the server 2 and installs it (Step 4). Then, the terminal 6 starts up the installed software 3 based on an operation performed by the user (Step 5).
The software 3, when started up on the terminal 6, generates the function information 5 to change the purchased fingerprint authentication function, which is the disallowed function 91, to the allowed function 90 to activate the fingerprint authentication function (Step 6). Starting up the software 3 causes the terminal 6 to have a function of reading the biometric information, i.e., fingerprints, with the touch detection unit 61.
After starting up the software 3, the user makes the terminal 6 read biometric information 60f, which is information of a fingerprint of an operating finger 10, to register biometric information used for fingerprint authentication to the start switch 82, as shown in
After the user gets in the vehicle 8, the terminal 6 transmits the function information 5, which is generated by the software 3, to the vehicle control device 80 through the vehicle LAN 7 (Step 7).
Once obtaining the function information 5 through the terminal 6 and the vehicle LAN 7, the vehicle control unit 80d of the vehicle control device 80 changes the fingerprint authentication function, which is the disallowed function 91, to the allowed function 90 based on the function information 5 (Step 8).
After the fingerprint authentication function is changed to the allowed function 90, the terminal 6 transmits the biometric information 60f of the operating finger 10, which is read for registration, as registered biometric information to the start switch 82 through the vehicle LAN 7 and the vehicle control device 80. A reading area 60e shown in
The start switch 82 performs biometric authentication by comparing the biometric information, which is read with the biometric authentication function when the operation is performed, to the biometric information 60f registered through the terminal 6.
(Effects of the Embodiment)
The vehicle control system 1 in the present embodiment is capable of easily adding new functions. In this vehicle control system 1, all executable functions of electronic devices mounted on the vehicle 8 are divided into the allowed functions 90 and the disallowed functions 91. Without having to purchase and install an electronic device that executes a desired function, the user can use the desired function by changing the disallowed function 91 to the allowed function 90 by the software 3 purchased from the server 2. Therefore, the vehicle control system 1 can easily add new functions without spending time and effort since the user does not need to purchase and install an electronic device having a desired function.
The vehicle control system 1 preliminarily includes substantially all functions executable by the plural electronic devices mounted on the vehicle 8. Therefore, it is not necessary to purchase electronic devices to add new functions and the cost is thus reduced.
In the vehicle control system 1, it is possible to change the allowed functions 90 and the disallowed functions 91 for each terminal 6. Therefore, as compared to when it is not possible to change, different functions can be available for different family members.
In the vehicle control system 1, when the vehicle 8 is used as a rental vehicle or a vehicle rented out for car sharing, a function of the electronic key can be changed to the allowed function 90 by purchasing the software 3 through the server 2 and can be rented without directly handing over the key to the contracted user. In addition, in the vehicle control system 1, it is possible to change available functions for each contracted user according to the amount of rental fee.
Although some embodiment and modifications of the invention have been described, these embodiment and modifications are merely examples and the invention according to claims is not to be limited thereto. These new embodiment and modifications thereof may be implemented in various other forms, and various omissions, substitutions and changes, etc., can be made without departing from the gist of the invention. In addition, not all combinations of the features described in these embodiment and modifications are necessary to solve the problem of the invention. Further, these embodiment and modifications thereof are included within the scope and gist of the invention and also within the invention described in the claims and the range of equivalency.
