- Patent Document 1 proposes an authentication function for functions related to a moving body.
- Patent Document 1 The function described in Patent Document 1 is an alternative authentication method that assumes that the vehicle is connected to a network. When a vehicle is traveling, it may travel through places where radio waves are difficult to reach, such as tunnels or deep in the mountains, and even if the vehicle's onboard equipment communicates, there is a possibility that a network connection failure will occur and the vehicle will go offline. If authentication is not possible in an offline environment, this may cause anxiety to the passengers and may cause problems while driving.
- the objective of this disclosure is to provide a vehicle control system, a vehicle control method, and a vehicle control program that can improve passenger convenience.
- a vehicle control system includes an Internet communication unit, an authentication unit, and a control unit.
- the Internet communication unit communicates with a server that stores information on paid functions that can be implemented by a vehicle occupant via a network.
- the authentication unit determines whether or not the paid function can be implemented via the Internet communication unit.
- the control unit enables the paid function to be implemented. If the authentication by the authentication unit fails, the control unit determines whether the occupant intends to charge an additional fee for the corresponding paid function, and if the control unit determines that the occupant intends to charge an additional fee for the corresponding paid function, the control unit enables the corresponding paid function to be executed. This improves the convenience for the occupant.

- Login information is required for online authentication with the external vehicle management server 8. If the occupant's (user's) login information has already been registered in the database 4e of the DCU 4, or if the identification information of the vehicle 2 has already been registered as login information in the database 4e of the DCU 4, the process proceeds to S127.
- the DCU 4 If it is determined in S124 that the occupant (user) is not a registered occupant and the identification number is not that of a registered vehicle 2, then in S125 the DCU 4 notifies the occupant of the vehicle 2 of a login request to log in. As a result of being notified of the login request, the occupant attempts to log in.
- Methods for authenticating the occupant's ID include authentication of the vehicle 2's identification information (such as the vehicle number), personal authentication using the occupant monitor of the detection unit 6a described above, and authentication by inputting an individual password. If the occupant succeeds in logging in, the process returns to S124 and a YES determination is made in S124.
- the DCU 4 references the contract information for the paid function of the logged-in occupant from database 4e, and determines in S127 whether the paid function is within its expiration date. If it is within its expiration date, the DCU 4 activates the paid function in S128. Conversely, if it is not within its expiration date, a notification is issued in S129 suggesting that the paid function contract be renewed. For example, it is advisable to notify the occupant of information such as "The subscription contract expired on XX/XX. would you like to renew it?" and encourage the renewal. If the renewal is approved, the DCU 4 communicates with the external management server 8, updates the contract information stored in database 4e or database 8a, and extends the expiration date.
- communication may be performed with the external management server 8 to compare and update the contract information for the fee-based function registered in the database 8a of the external management server 8.
- the authentication unit 4b If the network communication unit 4a performs communication processing with the external vehicle management server 8 via the network 7 and the network connection is interrupted due to reasons such as a weak radio reception environment, the authentication unit 4b is unable to authenticate whether or not the billing function can be implemented in S13 and determines that authentication has failed. In this case, the DCU 4 stores authentication history information indicating that authentication has failed in the database 4e.
- the DCU 4 fails to determine whether or not the charge system function can be implemented via the network communication unit 4a by the authentication unit 4b as a result of the disconnection of the network 7 in S14 (function of the alternative authentication unit 4c), the DCU 4 performs alternative authentication based on information stored in the memory unit 4d or memory unit 3a provided in the vehicle 2 (function of the alternative authentication unit 4c).
- the notification control unit 3d it is preferable for the notification control unit 3d to control notification of the result of the determination made by the alternative authentication unit 4c as to whether or not the charge system function can be implemented to the occupant. The occupant can then understand the result of the alternative authentication.
- the pay-per-use function may be allowed to continue unconditionally (function of the alternative authentication unit 4c). Also, if the DCU 4 is using a pay-per-use function when authentication by the authentication unit 4b fails and the DCU 4 makes a decision to stop the pay-per-use function, the pay-per-use function may be allowed to continue unconditionally without making a decision to stop the function (function of the alternative authentication unit 4c).
- the DCU 4 may determine that a paid function can be implemented and perform alternative authentication if the paid function to be determined whether it can be implemented falls into at least one of the following categories: a function necessary for the running of the vehicle 2, a function necessary for the safety of the user (passengers), or a function for making the internal environment of the vehicle 2 comfortable (function of the alternative authentication unit 4c). As will be explained individually below, the DCU 4 may determine that a paid function can be implemented if it falls into any two or more of these categories.
- the DCU 4 determines in S31 whether the charged function to be determined whether it can be implemented is a function necessary for the vehicle 2 to run, and if it determines that the function is necessary, the DCU 4 performs processing from S32 onwards using the function of the alternative authentication unit 4c.
- the user when driving the vehicle 2, the user sets the drive mode via the operation input unit 12 in order to change the driving performance of the vehicle 2.

- a service is provided that can adjust the driving performance of the vehicle 2 to performance suitable for driving on snowy roads.
- the DCU 4 Even if the DCU 4 cannot authenticate these drive modes as paid functions through the Internet communication unit 4a, if the DCU 4 determines in S31 that the functions are necessary for the vehicle 2 to travel, it determines in S32 that the target paid function can be implemented.
- the DCU 4 determines the importance of the target paid function in S33. This importance indicates the degree to which it is necessary for the vehicle 2 to run, and is set in advance in stages from necessary to high importance.
- the importance information is stored in advance in the memory unit 4d.
- the snow mode is one of the functions that is highly important for the vehicle 2 to run safely on snowy roads.
- the race drive mode is a relatively hobby-oriented mode, and is therefore one of the functions that is less important for the vehicle 2 to run.
- An example of setting the importance is given here, but the order of importance setting is not limited to this.
- the DCU 4 determines in S33 that the importance is lower than a predetermined level, then after obtaining consent through an operational instruction from the user in S34, it can activate the target paid function in S35 and make the subscription service of the paid function available. Conversely, if the DCU 4 determines that the importance of the target paid function is higher than a predetermined level, it can forcibly activate the target paid function in S35 without asking for instructions from the user and make the subscription service available. This allows the user to use the paid function in question.
- the vehicle 2 is provided with a manual driving mode and an automatic driving mode.
- the user changes the setting of the driving mode of the vehicle 2 by inputting an operation from the operation input unit 12.
- this driving mode is set, the driving control system ECU controls the driving of the vehicle 2 in accordance with this driving mode.

- the user can select the driving mode by operating the operation input unit 12.
- each function such as a radar cruise control function (LCC), an emergency stop function for collision prevention, and an accelerator depression prevention function can be selectively implemented.
- the DCU 4 Even if the DCU 4 cannot authenticate these driving modes as paid functions through the Internet communication unit 4a, if the DCU 4 determines in S41 of FIG. 4 that the functions are necessary for the safety of the occupants, it determines in S42 that the paid function in question can be implemented.
- the DCU 4 determines the importance of the target paid function. This importance indicates the degree to which it is necessary for the safety of the occupants, and is preset in stages, with the importance increasing from the most necessary function.
- the importance information is pre-stored in the memory unit 4d.
- the emergency stop function for collision prevention is a necessary and important function for preventing collisions with other vehicles 2 or obstacles, taking safety into consideration. For this reason, the importance is set to be relatively high.
- the accelerator depression prevention function is an important function for preventing collisions with obstacles, taking safety into consideration, and therefore the importance is set to be relatively high.
- the radar cruise control function is a function for following a vehicle 2 traveling in front of the vehicle 2 while maintaining a certain distance, and the importance is set to be relatively low compared to the emergency stop function and the accelerator depression prevention function.
- the order of importance setting is not limited to this.
- DCU4 determines in S43 that the importance is lower than a predetermined level, it obtains consent through an operational instruction from the user in S44, and then activates the target paid function in S45. Conversely, if DCU4 determines that the importance of the target paid function is higher than a predetermined level, it forcibly activates the target paid function in S45 without asking for instructions from the user. This allows the user to use the paid function.
- the target paid function is a paid function related to safety and security and has a higher level of importance than a predetermined level may be stored in the external management server 8 or the memory unit 4d. If the paid function is related to safety and security, the DCU 4 may activate the paid function unconditionally using the alternative authentication unit 4c. In this way, when the license authentication of the paid function fails, the DCU 4 will be able to execute the paid function unconditionally if the paid function to be authenticated is a function related to the safety and security of the occupants.
- the DCU 4 determines whether the chargeable function to be determined in step S52 is a comfort function for making the environment in the vehicle comfortable by using the alternative authentication unit 4c. If the DCU 4 determines that the chargeable function is a comfort function, it determines in step S53 that the chargeable function can be executed.
- the DCU 4 determines that the outside air temperature is lower than a predetermined standard temperature, it determines that the heating function for the interior of the vehicle can be performed using vehicle equipment 10 for heating, such as an air conditioner or a seat heater (function of the alternative authentication unit 4c).
- vehicle equipment 10 for heating such as an air conditioner or a seat heater (function of the alternative authentication unit 4c).
- the DCU 4 determines that the outside air temperature is higher than a predetermined standard temperature, it determines that the cooling function can be performed using vehicle equipment 10 for cooling, such as an air conditioner (function of the alternative authentication unit 4c).
- comfort functions include music distribution services and video and movie distribution subscription services. Even if the DCU 4 cannot authenticate the paid functions of these comfort functions through the Internet communication unit 4a, if the DCU 4 determines in S52 of FIG. 5 that the functions are necessary for comfort, it determines in S53 that the paid function in question can be implemented (function of the alternative authentication unit 4c).
- the DCU 4 determines the importance of the target paid function. This importance indicates the degree to which it is necessary to make the internal environment of the vehicle 2 comfortable, and is preset in stages, with the importance of the most necessary function increasing.
- the importance information is pre-stored in the memory unit 4d.
- the cooling/heating function for the vehicle interior is set to a relatively high importance, whereas the function of turning on the lights in the vehicle interior of the vehicle 2 is set to a relatively low importance.
- the order of importance is not limited to this.
- the DCU 4 determines in S54 that the importance is lower than a predetermined level, it obtains consent through an operational instruction from the user in S55, and then activates the target paid function in S56. Conversely, if the DCU 4 determines that the importance of the target paid function is higher than a predetermined level, it forcibly activates the target paid function in S56 without asking for instructions from the user. This allows the user to use the paid function.
- the DCU 4 obtains the result of alternative authentication performed by the alternative authentication unit 4c in S14, and notifies the alternative authentication result in S14a.
- the DCU 4 may display "Alternative authentication has succeeded (or failed)" (first notification information) on the display device 11 via the HCU 3.
- the DCU 4 may also communicate with the mobile terminal 9 and display this on the display screen of the mobile terminal 9.
- the DCU 4 may display "The function will continue. It can be used until the vehicle is stopped and the engine is turned off" (second notification information) on the display device 11 or the mobile terminal 9.
- the first and second notification information may be sent and notified in chronological order, or may be sent simultaneously.
- the DCU 4 may also display a predetermined special icon representing this alternative function on the display device 11 or mobile terminal 9 only during the period in which the function is permitted by the alternative authentication unit 4c.
- the DCU 4 determines whether all authentications by the alternative authentication unit 4c have failed in S15. If all authentications by the alternative authentication unit 4c have failed, the DCU 4 disables the subscription service of the target pay function in S20. If both authentications by the authentication unit 4b and the alternative authentication unit 4c have failed, the HCU 3 may notify the user of the reason for the authentication failure in S14b. For example, the reason may be, "Authentication failed due to a network connection loss.” This allows the vehicle occupant to understand why the vehicle cannot be used, and supports the vehicle occupant to avoid feeling distrustful. Although a network connection loss has been exemplified here, it is also preferable to notify the user of the reason if authentication fails due to a cause other than a connection loss to the network 7.
- the DCU 4 enables the billing function to be continuously used through authentication by the alternative authentication unit 4c, as described above with reference to Figures 3 to 5. Even after authentication by the alternative authentication unit 4c is complete, the DCU 4 determines in S16 whether authentication is possible through the network 7 by the authentication unit 4b. In other words, the DCU 4 determines whether online authentication is possible.
- DCU4 activates the billing function in S18 by being authenticated or confirmed by authentication unit 4b in S17.
- the result of the determination by alternative authentication unit 4c as to whether or not the billing function can be implemented remains valid until authentication by authentication unit 4b becomes possible. This is because alternative authentication by alternative authentication unit 4c becomes unnecessary if confirmation is given by authentication unit 4b.
- DCU4 transitions to S16 and continues to wait until authentication becomes possible. In other words, DCU4 continues to wait until online authentication becomes possible.
- the DCU 4 detects that the power switch of the vehicle 2 has been turned off without being authenticated by the authentication unit 4b, it determines NO in S16 and YES in S19. As a result, even if alternative authentication by the alternative authentication unit 4c has been performed for the target chargeable function, the DCU 4 disables the alternative authentication by the alternative authentication unit 4c on the condition that the power switch has been turned off.
- the DCU 4 holds the result of the determination by the alternative authentication unit 4c as to whether or not to implement the billing function valid until the vehicle 2 stops and the power supply to the vehicle 2 is cut off while authentication by the authentication unit 4b is not possible.
- the billing function was valid before driving began, it is conceivable that the validity period may expire while driving.
- the DCU 4 may determine that the billing function can be implemented unconditionally while the vehicle 2 is in operation.
- the power switch is turned off, the unconditional permission by the alternative authentication unit 4c is cancelled.
- the power switch is turned on again, authentication by the authentication unit 4b is required.
- the authentication unit 4b or alternative authentication by the alternative authentication unit 4c is required again, so that the contract for the billing function can be complied with.
- the DCU 4 may notify through the HCU 3 and the display device 11 or the mobile terminal 3 that authentication by the authentication unit 4b has failed, and immediately stop the billing function.
- the DCU 4 may use the alternative authentication unit 4c to determine whether the validity period of the billing function has elapsed using GPS or a timer, and determine whether or not the billing function can be implemented. As shown in FIG. 6A, the alternative authentication unit 4c may also use authentication history information for the billing function stored in the database 4e to determine whether or not the function can be implemented.
- the DCU 4 determines NO in S22 and does not allow alternative authentication by the alternative authentication unit 4c. At this time, it is recommended that the DCU 4 only accepts authentication by the regular authentication unit 4b. If authentication has never been successful, the target paid function is a function for which no charges have been made in the past. For this reason, it is recommended that alternative authentication not be allowed. As a result, it is possible to prevent unauthorized use of paid functions that should not have been available in the first place.
- FIG. 6B shows a modified example of FIG. 6A.
- the DCU 4 may display the reason why the function cannot be used on the display device 11 in S24.
- the DCU 4 causes the display device 11 to display a message via the HCU 3.
- the message displayed in this case may be, for example, "This function has never been used and there is no history of past authentication, so it cannot be used.” This allows the vehicle occupant to understand why it cannot be used, and supports the vehicle occupant to avoid causing distrust.
- the DCU 4 may also display a message such as "Would you like to be charged after communication is restored?" in S25 of FIG. 6B and suggest that a charge be made.
- the DCU 4 may determine in S63 using the authentication unit 4b whether or not the charging function can be implemented. If the DCU 4 fails to determine whether or not the charging function can be implemented in S63, the DCU 4 may forcibly determine in S64 using the alternative authentication unit 4c that the charging function can be implemented even while the vehicle 2 is traveling.
- the DCU 4 may regard the failure to determine whether or not to implement the paid function as being due to a deterioration in the radio communication conditions, and may forcibly permit alternative authentication by the alternative authentication unit 4c and continue to activate the paid function. This allows the occupant to continue using the target paid function.
- the authentication unit 4b fails to determine whether or not the billing function can be implemented via the network communication unit 4a, alternative authentication is performed by the alternative authentication unit 4c. This allows alternative authentication even in an offline environment.
- Fig. 7B A modified example is shown in Fig. 7B.
- the process at the start of the vehicle 2 will be described.
- the DCU 4 performs authentication by the authentication unit 4b in S222, and determines whether the authentication is successful in S223. If the authentication is successful, the DCU 4 activates a pay-per-use function in S224, but if the authentication is not successful, the DCU 4 checks the authentication history of the alternative authentication unit 4c in S225.
- the DCU 4 checks the authentication history by the alternative authentication unit 4c at the time the ignition switch was last turned off. Specifically, it checks whether the usage period of the paid function that can be implemented by the alternative authentication unit 4c has expired. If, for example, the alternative authentication by the alternative authentication unit 4c is within the validity period, the DCU 4 executes the alternative authentication by the alternative authentication unit 4c in S227. This makes it possible to realize an alternative function for the paid function, improving the convenience of the occupants.
- the DCU 4 determines that the authentication has failed more than a predetermined number of times after several retries, it displays the reason for the authentication failure on the display device 11 via the HCU 3 in S230.
- the HCU 3 displays a message such as "Authentication failed the last time the power was turned off, so it is not in a state where it can be used unconditionally" on the display device 11 to inform the occupant of the reason for the authentication failure. This allows the occupant to understand why they cannot use the pay-per-use function.
- the DCU 4 may notify the occupant via the HCU 3 and the display device 11 of the function for which authentication by the authentication unit 4b has failed, together with the reason for the authentication failure, that the function cannot be used. In this case, the occupant can understand the reason why the pay function cannot be used.
- Second Embodiment The second embodiment will be described with reference to Fig. 8 to Fig. 10C.
- an alternative function that substitutes for the charged function is searched for and the alternative function is executed.
- the DCU 4 has an application function as a search unit 4f that searches for the alternative function.
- the DCU 4 also has an application function as an authentication judgment unit 4g.
- the HCU 3 has an application function as a notification control unit 3d.
- the other configurations are the same as those in the first embodiment, so the description will be omitted.
- the DCU 4 uses the authentication unit 4b to determine whether or not the target charged function can be implemented via the network communication unit 4a. If the DCU 4 determines that the charged function can be implemented, it determines YES in S71 and implements the target charged function in S72.
- the DCU 4 determines in S71 whether or not the paid function can be implemented and determines in S73 that the target paid function cannot be implemented, it disables the paid function in S74. After this, the DCU 4 searches in S76 or S81, using the search unit 4f, for an app that executes an alternative function that satisfies the same conditions as the paid function and the intended use, regardless of the reason for whether or not the connection to the network 7 can be established.
- the DCU 4 judges YES in S75 and the authentication unit 4b judges that the pay-per-use function cannot be implemented due to a loss of communication connection with the network 7, it determines that it cannot connect via the Internet communication unit 4a. In this case, the DCU 4 may search for an app with an alternative function that can be implemented in an offline state, i.e., in a local environment, in S76 using the search unit 4f.
- the DCU 4 judges in S75 that the cause is an inability to connect to the Internet, it searches offline in S76 for an app with an alternative function that has the same purpose as the pay-per-use function.
- the DCU4 searches for apps pre-installed in the local environment inside the vehicle 2, for example in the memory unit 4d of the DCU4. If an app with an alternative function is stored in the memory unit 4d, the DCU4 determines that the alternative function can be implemented. When performing an offline search, the DCU4 may search for apps installed in the memory unit 3a of the HCU3.
- the DCU 4 may use the search unit 4f in S81 to search for an app with an alternative function that can be implemented either free of charge or for a fee from the external management server 8, etc.
- the DCU 4 determines in S75 that the cause is not an inability to connect to the Internet but an expiration of the contract or a failure in personal authentication, then in S81 it searches through the network 7 for an app that has an alternative function with the same purpose as the paid function.
- the DCU 4 searches through the network 7 using the search unit 4f, it may search for an app from the external vehicle management server 8, or it may search for an app from another server (not shown) through the network 7.
- This app may be a non-paid app or an app with the same function as the one stored offline in the memory unit 4d.
- the DCU 4 may also use the search unit 4f to search for alternative functions from among functions provided in the portable terminal 4 as an external terminal.
- the communication method during the search may be a local communication connection via the short-range wireless communication units 5 and 9b, or a communication connection via the network communication unit 4a and a connection server (not shown) through the network 7.
- an app with a subscription service's paid function may be targeted if there is an app with the same purpose and corresponding function.
- the DCU 4 may determine whether or not the app with the subscription service's paid function can be used.
- the app that performs the alternative function may be an app that provides a subscription service with a paid function, an app that provides a one-time paid function (so-called shareware), or an app that provides a non-paid function (so-called freeware), etc.
- the DCU 4 uses the search unit 4f to search for a driving control app that has the same purpose as the driving assistance.
- the DCU 4 uses the search unit 4f to search for map display apps with different titles or apps with other navigation functions.
- Navigation functions include, for example, a pay-per-use function that displays high-resolution 3D maps and searches the network 7 for accurate guidance to locations where various services can be provided.
- a pay-per-use function that displays high-resolution 3D maps and searches the network 7 for accurate guidance to locations where various services can be provided.
- an alternative function is provided that displays high-resolution 2D maps and provides route guidance.
- a local function that displays simplified maps and gives geographic guidance using only simple symbols. In this way, functions can be divided into stages.
- the DCU 4 can search online for apps with other functions from the network 7 via the Internet communication unit 4a.
- the DCU 4 can also search offline for apps that have been pre-stored in the storage units 3a and 4d. In this way, functions can be searched for in stages.
- the DCU 4 may search for only the map portion from the local storage units 3a and 4d.
- the HCU 3 may read out only the map portion searched for by the DCU 4 from the storage units 3a and 4d, use it, and display it on the display screen of the display device 11.
- the DCU4 may explore the functions of an app that authenticates people in a step-by-step manner.
- a person authentication app may have a paid function with relatively high-resolution recognition accuracy, and a local function with low-resolution recognition accuracy. The same is true for such person recognition apps.
- the DCU 4 may also download and store in advance in the storage unit 4d an app that allows the implementation of an alternative function when authentication by the authentication unit 4b fails. This allows the DCU 4 to immediately search for an alternative function that is permitted to be implemented by the search unit 4f.
- the search unit 4f searches for apps with the same comfort function purpose.
- the DCU 4 may search within the same category or genre using the search unit 4f.
- the HCU 3 may implement the app with the alternative function searched for by the search unit 4f of the DCU 4.
- An alternative function to a paid function may be a 100% alternative to the target paid function, or it may be an alternative to only a portion of the function.
- paid functions tend to be much more powerful than free apps. For this reason, even if you try to realize an alternative function to a paid function using only free functions, it is unlikely that you will be able to reproduce it 100%.
- DCU4 When DCU4 is to completely replace a paid function, it is recommended that it search for and use another paid app. For example, by searching for and using another audio app as the paid app, it is possible to receive radio in addition to playing music. When the audio app's functions become unusable due to an expired certification, DCU4 should use a different music app. This music app should search for an app that is capable of both playing music and receiving radio.
- DCU4 may search for and use an app that only has a music playback function and cannot receive radio.
- DCU4 may search for and use an app that only has a music playback function and cannot receive radio from the beginning.
- DCU4 may first search for an audio app that has both a music playback function and a radio function, and then, when the audio app with both functions becomes unusable due to an expired certification, DCU4 may search for and use an app that only has a music playback function and cannot receive radio.
- the app with alternative functions being searched for is an app related to safety or security, it may be given a high priority, other low-priority apps may be stopped, and apps determined to be low-priority may be deleted (trimmed) to free up memory capacity.
- the DCU 4 may use multiple alternative functions to implement an alternative function to reproduce a paid function that has been determined to be impossible to implement.
- the alternative function may be implemented by combining apps that can substitute for some of the functions to reproduce the paid function.
- the application may link with an external mobile terminal 9 and further link with other applications.
- the HCU 3 may have a music playback function as a local function 3c
- the mobile terminal 9 may have a radio reception function
- the external management server 8 may have an audio setting function.
- the DCU 4 may send and receive apps and data that exist in various places within the system, and may execute an add-on function for further adjustment.
- apps with adjustment functions may also be searched for from external mobile terminals 9, app servers, etc.
- a mediation app with a mediation function that mediates between the volume adjustment function when the navigation app provides guidance to a destination and the music volume adjustment function of the audio app may be searched for.
- the HCU 3 may receive the searched app from the DCU 4 and execute this mediation app together with the navigation app and the audio app.
- the HCU 3 may then selectively notify the vehicle interior of route guidance or music, allowing passengers to comfortably obtain route guidance information and enjoy music.
- we have explained the linkage and mediation between the navigation app and the audio app but it is a good idea to search for apps that can adjust, link, and work together with various apps and acquire them as apps with alternative functions.
- the DCU 4 If the DCU 4 is unable to find an alternative function through the network 7 using the search unit 4f in S81, it should determine NO in S82 and return to S76 to search for an alternative function that can be implemented in an offline state.
- the authentication unit 4b determines in S79 through the network communication unit 4a whether the alternative function can be implemented. If the authentication unit 4b determines that the alternative function can be implemented and the result of S79 is YES, the DCU 4 activates the application with the alternative function in S80. The HCU 3 then implements the application with the alternative function. The user can use the alternative function, improving user convenience. If the authentication unit 4b cannot perform online authentication in S79, the DCU 4 may perform offline alternative authentication through the alternative authentication unit 4c.
- the DCU 4 executes the process shown in FIG. 10A.
- the DCU 4 executes the application with the alternative function searched for by the search unit 4f in S83.
- this alternative function is substituting for a paid function, it is advisable to notify the occupant that the paid function has been disabled due to an expired authentication, so that the occupant is made aware of this. Examples of methods for this include (1) graying out the icon of the corresponding function, (2) removing the icon of the corresponding function from the menu screen, and (3) displaying information indicating that the function has been disabled in part of the screen.
- the displayed information may be text information or a mark indicating that the function has been disabled.
- the amount of information that can be displayed on the display screen of the display device 11 is limited.
- the HCU 3 periodically checks the icons displayed on the display device 11, and if the number of icons increases beyond a predetermined amount, it organizes the displayed information by reducing the displayed information to secure the display area or by deleting less important displayed information.
- the HCU 3 may display link information for moving to the authentication registration site for the paid function app.
- the occupant can select a link to the contact information, thereby accessing the registration site for the paid function using the browser function of the HCU 3 or display device 11.
- the telephone number, URL, and QR code (registered trademark) of the contact information may also be displayed.
- the DCU 4 may determine in S84 whether or not the authentication unit 4b can authenticate the paid function, even while the app with the alternative function searched for by the search unit 4f in S83 is being executed. If the DCU 4 determines in S85 that authentication of the paid function is possible, the HCU 3 may stop execution of the app with the alternative function in S86, and activate the paid function in S87. The HCU 3 may then prioritize execution of the app with the paid function. As a result, even while the app with the alternative function is being executed, if authentication of the regular app with the paid function becomes possible during the execution of the app with the alternative function, the app with the paid function can be executed with priority, improving user convenience.
- the priority of implementing the alternative function may be increased over the chargeable function of the subscription service.
- the DCU 4 may store this change in priority in the memory unit 4d, and refer to the priority in the memory unit 4d to determine which function to implement. In this case, the HCU 3 may prioritize the implementation of the alternative function over the chargeable function.
- the HCU 3 implements the alternative function searched for by the search unit 4f. Therefore, even if license authentication for the paid function of the subscription service fails from within the vehicle 2, the alternative function can be used to implement functionality at the same level as the paid function of the subscription service, or at the minimum level required by the occupants.
- a modified example of the second embodiment will be described below with reference to FIGS. 10B and 10C.
- the DCU 4 uses the authentication unit 4b to determine whether or not to implement the billing function. If there is no section where the signal is interrupted when the navigation application is being executed (NO in S281), the billing function can be activated as usual (S282). However, there are cases where it is possible to recognize in advance that there is a section where the signal is interrupted on the route of the navigation (YES in S281). Here, the DCU 4 determines in advance the possibility of a network connection failure, thereby determining in advance that the authentication unit 4b will be unable to authenticate the billing function.
- the DCU 4 notifies the occupant in advance via the HCU 3 that there is a section on the route where radio waves are interrupted (S283), and then searches for an alternative function from the portable terminal 9 (S284).
- the DCU 4 determines in S285 whether or not an alternative function is available, and if so, suggests to the occupant in S286 that the alternative function be implemented in the specific section.
- the DCU 4 accepts an operation input from the operation input unit 12, it stores the occupant's response in the memory unit 4d.
- the DCU 4 determines in S285 that there is no alternative function, it notifies the occupant via the HCU 3 and the display device 11 in S288 that the pay function may become unavailable in the specific section. If the DCU 4 determines in S289 that the pay function can be authenticated even when approaching the specific section, it exits this routine and executes the pay function as usual. Conversely, if the DCU 4 determines in S289 that the pay function can no longer be authenticated by approaching the specific section, it takes action in S290 according to the occupant's response that was previously stored in the memory unit 4d.
- the DCU 4 can execute the paid function as normal when approaching the specific section mentioned above if authentication of the paid function is possible. Conversely, if the DCU 4 determines that authentication of the paid function is no longer possible when approaching the specific section, it will respond in S290 according to the response of the occupant that was previously stored in the memory unit 4d. At this time, even if the paid function becomes unavailable, an alternative function previously set by the occupant can be executed, improving occupant convenience.
- the processes of S381 to S386 may be executed before searching for an alternative function from the mobile terminal 9 in S284.
- the DCU 4 refers to the storage unit 4d and determines in S381 whether a charged function whose expiration date is within a predetermined period (e.g., one day, two days, one week, etc.) is registered. If the expiration date is set to be within the predetermined period in S381, the DCU 4 notifies the occupant that there is a charged function whose expiration date is about to expire by using the function of the notification control unit 3d of the HCU 3 in S382. Then, the DCU 4 proposes updating the expiration date of the charged function in S383. If the occupant confirms the update, i.e., does not deny the update, the DCU 4 communicates with the external management server 8 in S386 to update the expiration date of the charged function and stores the result in the storage unit 4d.
- a predetermined period e.g., one day, two days, one week,
- the HCU 3 searches for an alternative function from the mobile terminal 9 in S284.
- the subsequent processing is similar to the processing in S285 to S290 in FIG. 10B, and therefore a description thereof will be omitted.
- the network communication unit 4a communicates via the network 7 with an external management server 8 that stores information on paid functions that can be implemented by the occupants of the vehicle 2, and the authentication unit 4b judges whether or not a paid function can be implemented via the network communication unit 4a.
- the authentication judgment unit 4g judges in advance whether authentication of the paid function by the authentication unit 4b will be impossible by determining in advance the possibility of at least one of the following situations occurring: a poor network connection or the expiration of the paid function.
- the notification control unit 3d is configured to notify the occupants when the authentication judgment unit 4g judges that authentication by the authentication unit 4b will be impossible.
- the DCU 4 also uses the search unit 4f to search for an alternative function that has the same purpose of use as the charged function, and if the authentication judgment unit 4g determines that authentication by the authentication unit 4b will be impossible due to a poor network connection, the notification control unit 3d suggests implementing the searched alternative function. For example, if the DCU 4 determines that there is a high possibility that connection to the network 7 will not be possible due to a route setting that causes radio waves to be interrupted, it determines that the function will not be usable for a long period of time and suggests implementing the alternative function. This makes it possible to make a thoughtful suggestion to the occupants by suggesting the implementation of an alternative function even if the charged function will not be usable for a long period of time.
- the DCU 4 may add the preferences of the occupant as a condition for determining the alternative function. For example, in the case of audio applications, it may search for applications with alternative functions that are strong in deep bass or treble, or for applications with alternative functions that emphasize preferences for music genres such as J-pop or jazz. In addition, in the case of the navigation function, it may be possible to set the background color to pastel or vivid, have the occupant input these preferences in advance on an options screen, or learn the audio setting input by the occupant.
- the DCU 4 searches for an alternative function using the search unit 4f, but if it determines that the authentication unit 4b will be unable to authenticate due to the expiration of the paid function, it is advisable to suggest to the occupant that the paid function be extended using the notification control unit 3d. For example, if the expiration date is set to expire after midnight, or if the expiration date is set to expire while the vehicle 2 is traveling, it is advisable to suggest to the occupant that the expiration date of the paid function be extended. It is also desirable to suggest to the occupant that the expiration date be extended if the expiration date is set to expire relatively soon, such as within a week or two.
- the third embodiment will be described with reference to Fig. 11A to Fig. 13B. In the third embodiment, differences from the first and second embodiments will be described.
- the DCU 4 performs authentication via the network 7 using the authentication unit 4b.
- the DCU 4 determines whether the authentication is successful using the authentication unit 4b.
- the DCU4 activates the pay-per-use function using the authenticated valid ID (personal authentication identification information) in S93.
- the user can use the pay-per-use function as usual.
- the DCU 4 determines in S94 whether the reason for the failure is a communication interruption due to a deterioration in the communication environment. If the communication was not interrupted, the DCU 4 determines NO in S94 and determines that personal authentication has failed. However, if the reason for the failure is a communication interruption, the DCU 4 inquires of the user in S95 whether or not the user intends to make an additional charge for the corresponding charged function by displaying the information on the display device 11 through the HCU 3 or by communicating with the mobile terminal 9. For example, during a trial period of one month or the like, the charged function or other charged functions may be available free of charge.
- the user may be notified of this and asked whether or not the user intends to make an additional charge. If the DCU 4 does not accept an approval operation through the operation input unit 12 for a predetermined period of time, the display of whether or not the user intends to make an additional charge may be erased.
- the DCU 4 determines in S96 whether or not there is an intention to charge an additional fee.
- the DCU 4 receives input indicating an intention to charge from the operation input unit 12 or the mobile terminal 9, it determines YES in S96 and determines that the user intends to charge an additional fee for the corresponding paid function. For example, if identification information such as a credit card number is stored in advance in the memory units 3a, 4d in the vehicle 2, the DCU 4 may regard this as an intention by the user to charge and automatically determine that there is an intention to charge an additional fee.
- the DCU 4 performs additional charging via the short-range wireless communication unit 5 through the mobile terminal 9, for example by credit card payment, and activates the charging function using the personal authentication information of the new ID.
- the corresponding charging function may then be implemented by the HCU 3 or the like.
- the mobile terminal 9 may transmit the certificate to the vehicle 2, making authentication possible even offline.
- the routine may be terminated as shown in FIG. 11A, but as shown in S95a of FIG. 11B, the DCU 4 may inquire of the occupant as to whether or not they wish to add a charge by linking it to a conventional ID that has existed for a long time. Then, if the occupant indicates their intention to charge in S96a, the DCU 4 may activate the charge system function with the conventional ID in S97a.
- the DCU 4 If it is determined that the occupant intends to be charged, and even while the HCU 3 is performing the corresponding charging function, the DCU 4 performs online authentication via the network communication unit 4a in S101 of FIG. 12. When the communication environment of the network 7 improves, the DCU 4 checks the information stored in the database 8a of the external management server 8 in S101.
- the DCU 4 determines whether the corresponding paid function can be used without additional charge. If the DCU 4 determines in S102 that the corresponding paid function can be used without additional charge, it may cancel the additional charge for the corresponding paid function in S103 and cancel the occupant's decision to charge additional charges. Furthermore, the new ID may be canceled in S104. Canceling the new ID is optional, and it may be canceled after confirming the occupant's intention to cancel. Thereafter, the HCU 3 becomes able to execute the corresponding paid function using the existing legitimate ID. As a result, the occupant can effectively use the paid function using the existing legitimate ID. Also, for example, the period during which additional charges were applied and the expiration date before the authentication expired may be compared, and if it is outside the expiration date, additional charges may be implemented.
- the DCU 4 may perform a refund process.
- it may notify the passenger of this via the display device 11.
- the message at this time may be, for example, "A refund process will be performed as a double charge has occurred," or "No additional charge was made as a charge had already been made. The function is functioning without additional charge.”
- the passenger can confirm whether they ended up being charged in vain, whether a refund was made after charging, or whether they were not charged at all, which prevents the passenger from feeling uneasy.
- ⁇ Modification 1> ⁇ Regarding button operations by passengers and display screen contents of the display device 11 while the vehicle is stopped, during automatic driving, or while the vehicle is traveling> For example, if the authentication by the authentication unit 4b fails due to a communication interruption in S94 of Fig. 11A, the driver is asked whether he/she wishes to be charged.

Here, the period for which charges have been incurred and its history information may be displayed for each paid function.
- ⁇ Modification 2> Regard the display of charging intention while the vehicle is traveling and the display screen contents of the display device 11> In particular, it is difficult for the driver to indicate his/her intention to charge additional fees while the vehicle is being driven manually, etc. For example, if the DCU 4 needs to inquire in detail about the intention to charge additional fees from the occupant, it may be necessary for the driver to input operations multiple times.
- charging conditions such as credit card number information, expiration date (charging method), and expiration date and validity count required when adding a charging function.
- the charging method indicates, for example, credit card number and expiration date information.
- charging conditions can include conditions for a charging period in units of, for example, one day, one week, one month, three months, six months, or one year, and conditions for the number of times such as once or three times while vehicle 2 is running. In such cases, it is not desirable for passengers in vehicle 2, especially the driver, to input operations multiple times. Therefore, it is advisable to perform all authentication by accepting a single button operation input.
- the operation buttons of the operation input unit 12 at this time may be icons displayed on the display screen of the display device 11 or physical buttons installed on the steering wheel or the like. In the case of icons, they are not normally displayed on the display screen of the display device 11.

- the intention to charge is set in advance in the storage unit 3a, 4d or the mobile terminal 9, for example, if the condition of S94 in FIG. 11A is met, the processing of S95 and S96 can be omitted and the charging function can be immediately activated in S97. Also, for example, if it is determined that the condition of S94 in FIG. 11B is not met, the processing of S95a and S96a can be omitted and the charging function can be immediately activated in S97a.
- the DCU 4 may determine whether or not the occupant intends to request additional charges for the relevant paid function not only when online authentication by the authentication unit 4b fails, but also when offline alternative authentication by the alternative authentication unit 4c fails.
- the DCU 4 performs authentication via the network 7 using the authentication unit 4b.
- the DCU 4 determines whether the authentication using the authentication unit 4b has been successful.
- DCU4 activates the pay-per-use function using the authenticated valid ID (personal authentication identification information) in S113.

- DCU 4 determines in S114 whether the reason for the failure is a communication interruption due to a deterioration in the communication environment. If there is no communication interruption, DCU 4 determines NO in S114, determines that personal authentication has failed, and exits the routine. However, if the reason for the failure is a communication interruption, DCU 4 substitutes the authentication by authentication unit 4b with alternative authentication unit 4c in S115. If authentication by alternative authentication unit 4c fails, DCU 4 asks the user in S117 whether he or she wishes to be charged for the corresponding fee-based function.
- the DCU 4 may make an inquiry from the mobile terminal 9 using communication of the short-range wireless communication unit 5, and in S118, it may determine whether or not there is an intention to make an additional charge.
- the DCU 4 receives an input indicating an intention to make a charge from the mobile terminal 9, it determines YES in S118 and determines that the user intends to make an additional charge for the corresponding charged function.
- the DCU 4 may make an additional charge using, for example, a credit card payment, and activate the charged function using a new ID (personal authentication information).
- the corresponding charged function may then be implemented by the HCU 3 or the like. Also, as shown in FIG.
- the DCU 4 may erase the inquiry display P in S118b and display a list of expired charged functions in S118c. It may also execute a process similar to that shown in ⁇ Modification 1>.
- the DCU 4 determines whether the occupant intends to make an additional payment for the corresponding paid function. Then, when the DCU 4 determines that the occupant intends to make an additional payment for the corresponding paid function, it enables the corresponding paid function to be implemented.

Abstract
Description
認証部による認証に失敗した場合に該当する課金制機能への乗員の追加の課金意思有無の判断を行い、制御部は、乗員が該当する課金制機能に対して追加の課金意思があると判断した場合、該当する課金制機能の実施を可能にしている。これにより乗員の利便性を向上できる。
第1実施形態について図1Aから図7Bを参照しながら説明する。図1Aに示す車両用システム1は、車両2の内部に設置されたHCU3、DCU4、及び、他のECU(図示せず)をネットワーク接続して備えると共に、車両2の外部に車外管理サーバ8をサーバ相当として備える。またユーザはスマートフォン、タブレット、又は、ノートパソコンなどの携帯端末9を車両2内又はその周辺で所持することがあり、この携帯端末9も車両用システム1を構成する。車両用システム1は、車両用認証システム及び車両用制御システムとして用いられる。
HCU3は表示系ECUを構成する。ECUはElectronics Control Unitの略であり電子制御装置である。HCU3は、プロセッサ、記憶部3a、I/O、これらを接続するバスを備えており、記憶部3aに記憶されたプログラムを実行することで各種の制御を実行する制御部として機能する。記憶部3aは、コンピュータによって読み取り可能なプログラム及びデータを非一時的に格納する非遷移的実体的記憶媒体(non-transitory tangible storage medium)を示す。非遷移的実体的記憶媒体は、半導体メモリなどにより実現される。HCU3には、近距離無線通信部5が接続されており、近距離無線通信部5により携帯端末9の近距離無線通信部9bとの間で通信可能になっている。
DCU4は、統合されたソフトウェアとハードウェアのプラットフォーム上で集中型のコックピット電子システムを構築するもので、データベース4eが構築された記憶部4dを搭載して構成されている。DCU4はDomain Control Unitの略を示す。
車両2に搭乗するユーザは携帯端末9を所持する。携帯端末9は、車室内に持ち込み可能な端末であり、操作入力用のインタフェース及び表示器等を備えている。携帯端末9は、各種の操作入力及び報知処理が可能な端末である。
<車外管理サーバ8との接続が良好な場合>
イグニッションスイッチや電源ボタンなどにより運転者が電源スイッチをオン操作すると、HCU3やDCU4などに電源投入される。DCU4のネット通信部4aはネットワーク7を通じて車外管理サーバ8との接続を確立し車外管理サーバ8との間でセッションを確立する。DCU4のネット通信部4aは車外管理サーバ8との接続が途切れていない限り、DCU4はネットワーク7を通じた通信状況が良好であると判断する。このときネット通信部4aは車外管理サーバ8との間で通信可能になる。
以下、車両2の走行中における処理動作について図2から図6Bを参照しながら説明する。図2のS11において、車両2が道路を走行中、ネット通信部4aはS12においてネットワーク7を通じて車外管理サーバ8との間の接続を持続できているか否かを定期的に判断する。
具体的には、図3に示すように、DCU4は、S31において実施可否を判断する対象となる課金制機能が車両2の走行に必要な機能であるか否かを判断した結果、必要であると判断した場合には、S32以降の処理を代替認証部4cの機能により実施する。
また図4に示すように、DCU4は、S41において実施可否を判断する対象となる課金制機能がユーザの安全のために必要な機能であるか否かを判断した結果、必要な機能であると判断した場合には、S42以降の処理を代替認証部4cにより実行する。
また図5に示すように、DCU4は、S52において実施可否を判断する対象となる課金制機能が車室内の環境を快適にするための快適機能か否かを代替認証部4cにより判断する。DCU4は、快適機能に該当すると判断した場合には、S53において対象の課金制機能を実施可能と判断する。
ここでは重要度の設定の一例を挙げたが、この重要度の順序設定に限られるものではない。
図7Bに変形例を示している。ここでは車両2の起動時の処理を説明する。車両2のイグニッションスイッチがオンされ車両2が起動すると、DCU4は、S222において認証部4bにより認証を行い、S223において認証成功したか否かを判定する。DCU4は、認証成功したときにはS224において課金制機能をアクティベートするが、認証成功しなければS225において代替認証部4cの認証履歴を確認する。
第2実施形態について図8から図10Cを参照しながら説明する。第2実施形態では、課金制機能を認証できない場合には、対象の課金制機能に代替する代替機能を探索して当該代替機能を実行する形態を説明する。
<第2実施形態の変形例その1>
第2実施形態の変形例その1について図10Bを参照して説明する。DCU4は、認証部4bにより課金制機能の実施可否を判断するが、ナビアプリが実行されているときに、電波の途切れる区間が存在しなければ(S281でNO)、通常通り課金制機能をアクティベートすればよい(S282)。しかし、ナビゲーションの道案内の経路上に電波の途切れる区間が存在することが予め認識できる場合がある(S281でYES)。ここでDCU4は、ネットワーク接続不良の発生可能性を事前に判断することで、認証部4bによる課金制機能の認証が不可能になることをあらかじめ判断している。
また、図10CのようにS284において代替機能を携帯端末9から探索する前にS381~S386のように処理を実行するようにしてもよい。DCU4は、記憶部4dを参照しS381において有効期限が所定期間内(例えば、1日、2日、一週間など)の課金制機能が登録されているか否かを判定する。DCU4は、S381において有効期限が所定期間内と設定されている場合、S382において有効期限切れが近い課金制機能があることをHCU3の報知制御部3dの機能により乗員に報知する。そしてDCU4は、S383において課金制機能の期限更新を提案する。乗員が更新を肯定、すなわち更新を否定しない場合には、DCU4はS386において課金制機能の期限を更新するように車外管理サーバ8と通信すると共に記憶部4dに記憶させる。
第3実施形態について図11Aから図13Bを参照しながら説明する。第3実施形態では、第1実施形態又は第2実施形態と異なる部分について説明する。図11Aに示すように、DCU4は、S91において認証部4bによりネットワーク7を通じて認証を行う。DCU4は、S92において認証部4bにより認証に成功したか否かを判断する。
<車両停車中、自動運転中、又は車両走行中における乗員によるボタン操作と表示装置11の表示画面内容について>
例えば、図11AのS94において認証部4bによる認証の失敗理由が通信途絶である場合には、乗員に追加で課金意思を問い合わせることになる。また、図11BのS94において認証部4bによる認証の失敗理由が通信途絶によらなかったとしても、S95aにおいて乗員に追加で課金意思を問い合わせることになる。
<特に車両走行中における課金意思表示と表示装置11の表示画面内容について>
特に運転手は、手動運転などで車両走行中に追加の課金の意思を示しにくい。例えば、DCU4が、乗員に対し追加の課金意思を問い合わせるときに詳細な問合せを必要としてしまう場合、何度も操作入力を必要とすることがある。
DCU4は、認証部4bによるオンライン認証に失敗した場合に限らず、代替認証部4cによるオフラインの代替認証に失敗した場合に、該当する課金制機能への乗員の追加の課金意思有無の判断を行ってもよい。
本開示は、前述した実施形態に限定されるものではなく、種々変形して実施することができ、その要旨を逸脱しない範囲で種々の実施形態に適用可能である。
前述実施形態では、DCU4が主体として認証処理を実行する形態を示したが、その一部又は全部の処理、機能を他の車載器(例えば、HCU3)が実行するようにしても良い。また逆に、HCU3に搭載されている機能を他の車載器(例えば、DCU4)が実行するようにしても良い。
その中でも、本開示の第1態様によれば、請求の範囲の記載内容に加え、以下の開示内容も含む。
