Degree DB 16, 3 rd application monitoring unit 17, 3 rd application execution unit 18 and API (Application Program Interface) -genre DB 19.

  The priority determination unit 12 is connected to the priority information creation unit 11, the native application information acquisition unit 13, the 3rd application management unit 15, the 3rd application monitoring unit 17, and the 3rd application execution unit 18. The priority information creation unit 11 and the 3rd application management unit 15 are connected to the 3rd application priority DB 16. The native application information acquisition unit 13 is connected to the native application priority DB 14. The 3rd application monitoring unit 17 is connected to the 3rd application execution unit 18. The 3rd application execution unit 18 is connected to the API-genre DB 19.

  The native application priority DB 14 and the 3rd application priority DB 16 correspond to an application information storage unit. The API-genre DB 19 corresponds to a genre storage unit.

  The priority determination unit 12 includes, for example, a central processing unit (abbreviation: CPU) and a memory such as a writable RAM (Random Access Memory). The memory stores a control program for the priority determination device 1.

  The priority determination unit 12 includes a priority information creation unit 11, a native application information acquisition unit 13, a 3rd application management unit 15, and a 3rd application monitoring unit 17 that configure the priority determination device 1 according to a control program stored in the memory. And 3rd application execution unit 18 are controlled in an integrated manner. Functions of the priority information creation unit 11, the native application information acquisition unit 13, the 3rd application management unit 15, the 3rd application monitoring unit 17, and the 3rd application execution unit 18 by the CPU executing the control program stored in the memory Is realized.

  The native application priority DB 14, the 3rd application priority DB 16, and the API-genre DB 19 are configured by, for example, a hard disk drive (abbreviation: HDD) device or a storage device such as a semiconductor memory.

  In the following description, application software that realizes a specific function may be referred to as an “app”. In addition, an application installed in advance in a device on which the application is executed may be referred to as a “native application”. In addition, a 3rd party application may be referred to as a “3rd application”. In addition, application software for which priority for execution is not determined may be referred to as “undecided application”, and application software for which priority for execution is already determined may be referred to as “determined application”.

  If the priority input device 1 is an undecided app whose priority to be executed is not determined, for example, an app input from an external device or database (DB), for example, a 3rd app, , Determine the priority of undecided apps.

  The priority of the application is set for each genre of the application, and is set for each application within the same genre. That is, the priority value indicating the priority of the application is prepared in advance for each genre. The priority value of each application belonging to each genre is selected from the range of possible priority values.

The priority between genres is, for example, in descending order of priority.
Safety> Accessory control>Navigation>Entertainment> Others. That is, a safety-related genre, an accessory control genre (hereinafter referred to as “accessory control genre”), a navigation genre (hereinafter referred to as “navigation genre”), an entertainment genre (hereinafter referred to as “entertainment genre”), and other genres. , The priority is low.

  The safety-related genre corresponds to an alarm warning genre, which is a genre of an application related to an alarm warning. The accessory control genre is a genre of an application related to the control of the accessory device of the vehicle when the priority determination device 1 is mounted on the vehicle. The navigation genre is a genre of an application related to real-time information notification. The entertainment genre is a genre of an application related to entertainment that is allowed to be used while the vehicle is running. The other genres include non-permitted genres that are genres of applications that are not permitted to be used while the vehicle is running.

  The priority value of the app is, for example, a priority offset value by genre that is an offset value of a priority value set for each genre, and an in-genre priority value that is a priority value representing a priority in the genre. Expressed in sum. That is, the priority value of the application is expressed by the following formula.

      App priority value = priority offset value by genre + priority value within genre

  Table 1 shows an example of priority values that can be taken by each genre, priority offset values by genre, and genre codes. The priority values, genre-specific priority offset values, and genre codes shown in Table 1 are examples, and are not limited thereto. A priority value represents that a priority is so high that the value is small. In the present embodiment, the priority value is represented by an integer of 1 or more. Therefore, the highest priority value is “1”. In each genre, high priority means that the priority value is small in the genre.

  The higher the priority of an application, the higher priority is given to output operations such as audio output and video display when the application is executed. Further, the application can preferentially use resources such as a storage area as the priority is higher. When CPU resources or execution memory is insufficient, sleep or forced termination is performed from an application with low priority. In this case, sleep first, and if it still runs short of resources, it is forcibly terminated.

  The app is given to the priority determination device 1 together with profile information that is information about the app. An example of app profile information is shown in Table 2.

  For example, as shown in Table 2, the profile information identifies the application name that is the name of the application, genre information that represents the genre of the application, priority candidate values that are candidates for priority values that represent the priority of the application, and the application. Including any or all of the identification information. Genre information is represented by a genre code, for example. The identification information is, for example, an application identifier. For example, as shown in Table 2, the application identifier is represented by an identifier character that is a character representing the identifier.

  In the present embodiment, the profile information includes at least a priority candidate value and an application identifier. The profile information may include download source information indicating the download source of the application. The download source information corresponds to information related to an application supply source that supplies the application.

  As shown in Table 2, the priority candidate value may be included in the profile information as an intra-genre priority candidate value that is a candidate for an intra-genre priority value. When the genre priority candidate value is not set, the value of the genre priority candidate value included in the profile information is zero (0) or null.

  As shown in Tables 1 and 2, for example, in the case of a navigation genre, the genre-specific priority offset value is 20, and the in-genre priority candidate values are 1-10.

  Here, when the candidate priority value in the genre of the “congestion information application” is “3”, the priority offset value by genre of the navigation genre is “20” from Table 1, so that the true value of the “congestion information application” The priority candidate value of “2” is “23” by adding “3” to “20” and 20 + 3 = 23.

  The native application information acquisition unit 13 manages profile information of a native application that is information related to a native application that is an application introduced in advance. For the native application, the priority for execution is already determined, and corresponds to the determined application. The native application priority DB 14 stores priority information indicating the priority of the native application, specifically a priority value.

  The 3rd application management unit 15 manages the 3rd application and profile information of the 3rd application, which is information related to the 3rd application. The 3rd application priority DB 16 stores priority information indicating the priority of the already determined 3rd application, specifically, a priority value. The 3rd application whose priority information is stored in the 3rd application priority DB 16 corresponds to a determined application.

  The priority determination unit 12 determines the priority of the undecided application based on, for example, the priority information of the native application stored in the native application priority DB 14 and the priority information of the 3rd application stored in the 3rd application priority DB 16. Determine the degree.

  The priority determination unit 12 may determine the priority of the undecided application using the 3rd application monitoring unit 17, the 3rd application execution unit 18, and the API-genre DB 19. The 3rd application execution unit 18 executes the 3rd application based on an instruction from the priority determination unit 12. The 3rd application monitoring unit 17 monitors the operation status of the 3rd application when the 3rd application is executed by the 3rd application execution unit 18.

  The API-genre DB 19 associates, with respect to a native app that is a determined app and a previously introduced 3rd app, an operation status when each app is executed and genre information representing the genre of the app. Remember. Specifically, the API-genre DB 19 stores an API list in which genre information of an application is associated with an API called when the application is executed. Table 3 shows an example of the API list.

  As shown in Table 3, for example, an API of “mixer initialization” that initializes a mixer is associated with an application that realizes audio and video functions. An API for “GPS initialization” that initializes data of a GPS sensor that detects a position using a global positioning system (abbreviation: GPS) is associated with an application that realizes a navigation function.

  The API of “air conditioner ON” for turning on the air conditioner (hereinafter referred to as “air conditioner”), that is, starting the operation of the air conditioner, is associated with an application that realizes the function of the air conditioner. The “wiper ON” API that turns on the wiper, that is, starts the wiper operation, is associated with an application that realizes the function of the wiper.

  For example, the priority determination unit 12 causes the 3rd application execution unit 18 to execute an undecided application, and causes the 3rd application monitoring unit 17 to monitor the API called at that time. The priority determination unit 12 acquires an API list from the API-genre DB 19, compares the acquired API list with an API called by an undetermined application, and generates a genre corresponding to the API called by the undetermined application. Is obtained as genre information of an undetermined application. The priority determination unit 12 determines the priority of the undecided application based on the determined genre information of the undecided application and the priority of the determined application stored in the 3rd application priority DB 16.

  The priority information creation unit 11 creates priority information representing the priority determined by the priority determination unit 12, and uses the created priority information as priority information for an undetermined application in the 3rd application priority DB 16. Remember. In the present embodiment, the priority information of the undetermined application is stored in the 3rd application priority DB 16 in association with the genre information of the undetermined application.

  2 to 4 are flowcharts showing a processing procedure related to the priority determination process of the priority determination device 1 according to the first embodiment of the present invention. Each process of the flowcharts illustrated in FIGS. 2 to 4 includes a priority information creation unit 11, a priority determination unit 12, a native application information acquisition unit 13, a 3rd application management unit 15, and a 3rd application monitoring unit 17 of the priority determination device 1. And the 3rd application execution unit 18.

  In FIGS. 2 to 4, a newly downloaded application (hereinafter sometimes referred to as “new download application”) is assumed as an undecided application whose priority has not been determined, and the priority of the new download application is determined. The processing procedure is shown. The flowchart showing the processing of the priority determination apparatus 1 in FIGS. 2 to 4 is started when a new download application is downloaded from a device external to the priority determination apparatus 1 or a database, and the process proceeds to step a1.

  In step a1, the priority determination unit 12 acquires profile information of a new download application. The newly downloaded application is given to the priority determination unit 12 together with profile information that is information about the application.

  In step a3, the priority determination unit 12 determines whether or not the new download application can be trusted. In the present embodiment, the priority determination unit 12 determines whether or not the download source of the new download application is reliable based on the profile information of the new download application acquired in step a2.

  Specifically, the priority determination unit 12 extracts the download source information from the profile information of the new download application. The priority determination unit 12 displays a list of download sources stored in advance in a memory (not shown) as a reliable download source (hereinafter referred to as a “trusted download source list”) as the download source represented by the downloaded download source information of the newly downloaded application. Is included).

  If it is determined that the download source of the new download application is included in the trusted download source list, it is determined that the download source of the new download application is reliable, and the process proceeds to step a3. If it is determined that the download source of the new download application is not included in the trusted download source list, it is determined that the download source of the new download application is not reliable, and the process proceeds to step a4.

  In order to determine whether or not the newly downloaded application can be trusted in step a3, information regarding the application creator that created the application (hereinafter also referred to as “app creator information”) may be used. Also, authentication information for authenticating the application may be used. When using authentication information, for example, by verifying that the application has not been tampered with using the signature information given to the application, whether or not the newly downloaded application can be trusted, such as by authenticating the application You may judge.

  In step a3, the priority determination unit 12 determines whether there is genre information in the profile information of the newly downloaded application acquired in step a1, that is, whether the profile information of the newly downloaded application includes genre information. To do. If it is determined in step a3 that there is genre information, the process proceeds to step a5. If it is determined that there is no genre information, the process proceeds to step a21 in FIG.

  In step a4, the priority determination unit 12 sets the lowest priority value among the values prepared in advance as possible priority values as the priority value of the new download application. After the process of step a4 is complete | finished, it transfers to step a18 of FIG.

  In step a5, the priority determination unit 12 determines whether or not there is a priority candidate value, specifically, an in-genre priority candidate value, in the profile information of the new download application acquired in step a1, that is, the new download application. It is determined whether or not the profile information includes a priority candidate value. In step a4, when it is determined that there is a priority candidate value, the process proceeds to step a7. When it is determined that there is no priority candidate value, the process proceeds to step a6.

  In step a6, the priority determination unit 12 sets a provisional value as a priority candidate value. Specifically, the priority determination unit 12 assumes that the priority candidate value is Null, that is, does not exist, and as the temporary priority candidate value, for example, the lowest priority value or the lowest priority value 4 A value of about 3 (3/4) is set.

  For example, when the genre of the new download application is navigation, specifically, the genre of car navigation, the lowest priority value of the navigation genre is “30” from Table 1, so the priority value is 30. That is, the genre priority value is set to 10, or the genre priority value is rounded up from 10 × 3/4 = 7.5, and the genre priority value is 8, Is set to 28.

  In step a <b> 7, the priority determination unit 12 acquires a native application priority table from the native application priority DB 14 via the native application information acquisition unit 13. The native app priority table is a list showing the native app and the priority of the native app.

  In step a8, the priority determination unit 12 may download a 3rd application (hereinafter referred to as “downloaded application”) from the 3rd application priority DB 16 via the 3rd application management unit 15 before the newly downloaded application. ) Priority table. The downloaded application priority table is a list showing downloaded applications and the priority of the downloaded applications.

  In step a9, the priority determination unit 12 extracts a part of the same genre as that of the new download application from the priority table of the native application acquired in step a7 based on the genre information of the new download application.

  In step a10, the priority determination unit 12 extracts a part of the same genre as the newly downloaded application from the priority table of the downloaded application acquired in step a6 based on the genre information of the newly downloaded application. After the process of step a10 is complete | finished, it transfers to step a11 of FIG.

  In step a11 of FIG. 3, the priority determination unit 12 determines the part extracted in steps a9 and a10, that is, the part extracted from the priority table of the native application in step a9, and the priority table of the downloaded application in step a10. A new priority table (hereinafter may be referred to as “application priority table”) is created by combining with the portion extracted from.

  In step a12, the priority determination unit 12 searches the application priority table created in step a11. In the present embodiment, the priority determination unit 12 searches the application priority table created in step a11 in order from the highest priority value.

  In step a13, the priority determination unit 12 determines whether there is an application having the same priority value as the priority candidate value of the newly downloaded application from the search result in step a12. If it is determined in step a13 that there is an application having the same priority value as the priority candidate value of the new download application, the process proceeds to step a15, and an application having the same priority value as the priority candidate value of the new download application is found. If it is determined that there is not, the process proceeds to step a14.

  In step a14, the priority determination unit 12 sets the priority candidate value of the new download application as the priority value of the new download application. After the process of step a14 is complete | finished, it transfers to step a18.

  In step a15, the priority determination unit 12 determines a priority value prepared in advance as a priority value to be assigned to an application of the same genre as the new download application (hereinafter referred to as “priority value for the same genre as the new download application”). In other words, it is determined whether there is an unused priority value among the priority values that can be taken by an application of the same genre as the newly downloaded application.

  Specifically, the priority determination unit 12 searches the part extracted from the priority table of the downloaded application in step a10, for example, in order from the highest priority value, and for the same genre as the newly downloaded application. It is determined whether there is an unused priority value among the priority values.

  In step a16, when it is determined that there is an unused priority value among the priority values for the same genre as the newly downloaded application, the process proceeds to step a17 and the priority for the same genre as that of the newly downloaded application is set. If it is determined that there is no unused priority value among the values, the process proceeds to step a16.

  In step a16, the priority determination unit 12 sets the lowest value of the priority values for the same genre as the new download application as the priority value of the new download application.

  In step a17, the priority determination unit 12 sets one of the unused priority values among the priority values for the same genre as the new download application as the priority value of the new download application. Specifically, the priority determination unit 12 sets the highest priority value among the unused priority values as the priority value of the newly downloaded application. For example, the priority determination unit 12 may use the lowest priority value among the unused priority values as the priority value of the newly downloaded application.

  In step a18, the priority determination unit 12 provides the priority information creation unit 11 with the priority value determined in step a14, step a16, or step a17. In step a19, the priority information creating unit 11 creates priority information representing the priority value from the priority value given from the priority determining unit 12 in step a18.

  In step a20, the priority information creation unit 11 gives the priority information created in step a19 to the 3rd application priority DB 16 as the priority information of the newly downloaded application. The 3rd application priority DB 16 stores priority information given from the priority information creation unit 11. After the process of step a20 is completed, the process returns to step a1.

  When the process proceeds from step a3 in FIG. 2 to step a21 in FIG. 4, in step a21, the priority determination unit 12 sets the application identifier of the newly downloaded application included in the profile information of the newly downloaded application to the 3rd application monitoring unit 17. To give.

  In step a22, the 3rd application monitoring unit 17 acquires a list of APIs registered in the API-genre DB 19. In step a23, the 3rd application monitoring unit 17 starts monitoring the API called by the new download application being executed.

  In step a24, the priority determination unit 12 instructs the 3rd application execution unit 18 to execute the new download application with the lowest priority value. In step a25, the 3rd application execution unit 18 executes the new download application with the lowest priority value in accordance with the instruction from the priority determination unit 12.

  In step a <b> 26, the 3rd application monitoring unit 17 determines whether the newly downloaded application being executed by the 3rd application execution unit 18 has called an API registered in the API-genre DB 19. If it is determined in step a26 that the new download application being executed has called the API registered in the API-genre DB 19, the process proceeds to step a28, and the new download application being executed is registered in the API-genre DB 19. If it is determined that the API has not been called, the process proceeds to step a27.

  In step a27, the priority determination unit 12 sets the lowest priority value among all the priority values prepared in advance as priority values to be assigned to the application as the priority value of the newly downloaded application. In step a28, the 3rd application monitoring unit 17 searches the API-genre DB 19 and acquires genre information corresponding to the called API.

  In step a29, the 3rd application monitoring unit 17 gives the genre information acquired in step a28 to the priority determining unit 12 together with the application identifier of the newly downloaded application. After the process of step a29 is complete | finished, it transfers to step a5 of FIG. 2, and the process after step a5 is performed as mentioned above.

  Table 4 shows an example of the priority table of downloaded applications acquired in step a8. In Table 4, the left column indicates the genre of the downloaded application, and the right column indicates the name of the downloaded application, the priority value within the genre, and the candidate value within the genre. In the following description, the name of the application may be referred to as “application name”.

  The numerical values in parentheses in the right column of Table 4 are the in-genre priority value and the in-genre priority candidate value of the downloaded application. The in-genre priority candidate value is included in the priority table when the in-genre priority candidate value is included in the profile information of the downloaded application. When the genre priority candidate value is not included in the profile information of the downloaded application, the genre priority candidate value is not included in the priority table. For example, in the case where the profile information of the social networking site (abbreviated as SNS) application shown in Table 4 does not include the genre priority candidate value, the parenthesis in the right column of Table 4 indicates the priority within the genre. The degree candidate value is not described, and only “3” which is the intra-genre priority value is described.

  An example of the priority table of the native application acquired in step a7 is shown in Table 5. In Table 5, the left column indicates the genre of the native application, and the right column indicates the name of the native application and the priority value in the genre. The numerical value in the parenthesis in the right column of Table 5 is the priority value within the genre of the native application. In Table 5, the symbol “-” indicates that there is no corresponding application.

  Table 6 shows an example of profile information given to the priority determination unit 12 together with the new download application. In Table 6, the left column indicates the genre of the new download application, and the right column indicates the name of the new download application and the priority value within the genre.

  For example, as shown in Table 6, let us consider a case where the name of the new download application is “Internet navigation”, the genre is navigation, and the in-genre priority candidate value is “3”. In this case, in the above-described step a9 and step a10, the “navigation” genre part, which is the genre of the newly downloaded application, is extracted from the priority table of the native application and the priority table of the downloaded application. Table 7 shows an example of the application priority table created by combining the extracted parts.

  In step a12, the application priority table as shown in Table 7 is searched in order from the highest priority value. In step a13, whether or not there is an application having the same priority value as the priority candidate value of the new download application, specifically, an application having the same in-genre priority value as the in-genre priority candidate value of the new download application. It is determined whether or not there is.

  For example, as shown in Table 6, in the case where the in-genre priority candidate value of the new download application is “3”, in step a13, the application having the same in-genre priority candidate value as the in-genre priority candidate value of the new download application. It is determined that there is, and the process proceeds to step a15. In step a15, the part extracted from the priority table of the downloaded application is searched in order from the highest priority value. Among the priority values for the same genre as the newly downloaded application, unused priority values are searched. Specifically, it is determined whether there is an unused in-genre priority value among the in-genre priority values for the same genre as the newly downloaded application.

  For example, when an integer of “3” to “10” is prepared as the in-genre priority value for the downloaded application, “3” indicates the in-genre priority value of the traffic jam information application as shown in Table 7. However, the integers “4” to “10” are not used. Accordingly, in step a15, it is determined that there is an unused genre priority value, and the process proceeds to step a17.

  In step a17, one of the integers “4” to “10” that is an unused genre priority value, for example, “4” that is the highest priority value is the genre of the newly downloaded application. The inner priority value is determined. The determined in-genre priority value is given to the priority information creating unit 11 in step a18. The priority information creation unit 11 creates priority information from the given genre priority value. An example of the priority information created in this way is shown in Table 8.

  As shown in Table 8, the priority information includes, for example, genre information representing an application genre, an application name, an in-genre priority value, and an in-genre priority candidate value. In Table 8, the in-genre priority value and the in-genre priority candidate value are numerical values in parentheses. As shown in Table 8, the in-genre priority value of the Internet navigation application that is a new download application is determined to be “4”, for example.

  As described above, according to the priority determination device 1 of the present embodiment, the native application priority DB 14 and the 3rd application priority DB 16 include the priority indicating the priority of the native application and the downloaded application that are already determined applications. Each piece of information is stored. In the present embodiment, based on the priority information stored in the native application priority DB 14 and the 3rd application priority DB 16, or based on the operation status when the 3rd application execution unit 18 executes a new download application, The priority determination unit 12 determines the priority of the new download application.

  This determines the priority of the newly downloaded app so that the new downloaded app can operate with the existing native app and downloaded app without compromising the functionality of the newly introduced new downloaded app. can do.

  In particular, in this embodiment, when it is determined in step a3 of FIG. 2 that there is no genre information in the profile information of the newly downloaded application, the priority of the newly downloaded application is the new download by the 3rd application executing unit 18. It is determined based on the operation status when the application is executed.

  In the method of determining the priority using the genre information described above, if the genre information of the new download application cannot be acquired, the new download is performed based on the priority information stored in the native application priority DB 14 and the 3rd application priority DB 16. Unable to determine app priority.

  On the other hand, the priority determination unit 12 of the priority determination device 1 according to the present embodiment executes the new download application by the 3rd application execution unit 18 when there is no genre information in the profile information of the new download application. The priority of the newly downloaded application is determined based on the operation status at the time. Thereby, even when genre information is not given to the newly downloaded application, the priority of the newly downloaded application can be determined.

  When determining the priority of the new download application based on the operation status in this way, the priority determination unit 12 first determines the operation status when the 3rd application execution unit 18 executes the new download application, and the API-genre. Based on the operation status and genre information stored in the DB 19, the genre information of the new download application is obtained. Then, the priority determination unit 12 prioritizes the new download application based on the genre information of the newly downloaded application and the genre information and priority information stored in the native application priority DB 14 and the 3rd application priority DB 16. Determine the degree. As a result, the priority of the new download application can be easily determined.

  In the present embodiment, when the profile information of the undetermined application does not include genre information, the priority determination unit 12 estimates the genre from other profile information excluding the genre information, and uses the estimated genre to determine the genre information. Determine the priority of the decision app. Thereby, even when the profile information does not include genre information, the priority of the undetermined application can be determined.

  In the present embodiment, when the genre of the undetermined application cannot be estimated, the priority determination unit 12 determines the genre having the lowest priority as the genre of the undetermined application. Thereby, even when the genre of the undetermined application cannot be estimated, the genre of the undetermined application can be determined and the priority of the undetermined application can be determined based on the genre.

  In the present embodiment, when the profile information of the undetermined application includes the priority candidate value, the priority determination unit 12 includes the priority candidate value, the profile information of the native application and the downloaded application that are existing applications, To determine the priority of the undecided app. As a result, the undetermined application can be smoothly operated together with the native application and the downloaded application.

  In the present embodiment, the profile information of the downloaded application includes the priority value and priority candidate value determined by the priority determination unit 12, specifically, the intra-genre priority value and the intra-genre priority candidate value. including. The priority determination unit 12 determines the priority value of the undecided application based on the priority value and priority candidate value of the downloaded application and the priority candidate value of the undecided application. As a result, the priority can be appropriately determined between newly-introduced undecided apps and previously-introduced apps, so that undecided apps and downloaded apps can operate more smoothly. Can be made.

  In the present embodiment, the priority determination unit 12 estimates the genre of the undetermined application or is acquired from the profile information, but is estimated or acquired when the priority of the undetermined application cannot be estimated. The priority of the undetermined application is determined so that the priority is lowest in the genre of the undetermined application. As a result, the priority of the undetermined application can be determined so as not to hinder the operation of other applications.

  Further, in the present embodiment, the priority determination unit 12 acquires download source information from profile information of a new download app that is an undecided app, and the download source of the new download app is trusted based on the acquired download source information. It is determined whether or not it can be performed, and the priority value of the newly downloaded application is determined in step a4, step a13, step a15, or step a16 according to the determination result.

  In other words, the priority determination unit 12 acquires download source information from the profile information of a newly downloaded app that is an undecided app, and based on the acquired download source information, the reliability of the undecided app, specifically, The reliability of the profile information of the undetermined application is estimated, and the priority of the undetermined application is determined based on the estimated reliability. As a result, the risk due to the undetermined application can be suppressed.

  In determining whether or not the newly downloaded application can be trusted, either or both of the application creation source information and the authentication information may be used instead of the download source information or together with the download source information. The download source information, application creation source information, and authentication information may be included in the profile information or may not be included in the profile information. When such information is included in the profile information, the profile information may be used for determining whether or not the new download application can be trusted.

  That is, the priority determination unit 12 acquires at least one of profile information, download source information that is information about an application supplier, information about an application creator, and authentication information, and based on the acquired information, The reliability of the profile information of the undetermined application may be estimated, and the priority of the undetermined application may be determined based on the estimated reliability. Whichever information is used, the same effect as in the present embodiment can be obtained.

  The priority determination apparatus 1 according to the present embodiment is configured to be able to acquire at least one of profile information of native apps, profile information of downloaded apps, and profile information of undecided apps from the outside. . Thereby, the priority determination device 1 can be realized with a simple configuration.

  Further, in this embodiment, the genre is permitted to be used for alarm warning genre related to alarm warning, accessory control genre related to control of vehicle accessory devices, navigation genre related to real-time information notification, and use while the vehicle is running. Entertainment genres related to entertainment that is present, and non-permitted genres that are not allowed to be used while the vehicle is running. The priorities of these genres are set so that the priorities become lower in the order of alarm warning genre, accessory control genre, navigation genre, entertainment genre, and non-permission genre. By setting in this way, an appropriate priority can be determined according to the genre of the application.

  In the present embodiment described above, the priority value of the downloaded application that is the downloaded application is not changed in the processing of the flowcharts shown in FIGS. Not limited to this, if the priority value of a downloaded application is the same as the priority candidate value of a newly downloaded application that is an undecided application, the priority candidate value of the downloaded application and the priority of the newly downloaded application The degree candidate values may be compared and rearranged in descending order of priority candidate values.

  In step b14, the priority determination unit 12 extracts the part extracted in step b12 and step b13, that is, the part extracted from the priority table of the native application in step b12 and the priority table of the downloaded application in step b13. Combine the parts and create an app priority table.

  In step b15, the priority determination unit 22 searches the application priority table created in step b14 in order from the highest priority value.

  In step b16, the priority determination unit 22 determines whether there is an application having the same priority value as the priority candidate value of the newly downloaded application acquired in step b10 from the search result in step b15. If it is determined in step b16 that there is an application having the same priority value as the priority candidate value of the newly downloaded application, the process proceeds to step b18 in FIG. 8 and the same priority value as the priority candidate value of the newly downloaded application. If it is determined that there is no app, the process proceeds to step b17.

  In step b17, the priority determination unit 22 sets the priority candidate value of the new download application as the priority value of the new download application. After the process of step b17 is complete | finished, it transfers to step b21 of FIG.

  In step b18 of FIG. 8, the priority determination unit 22 determines whether there is an unused priority value among the same priority values for the genre as the newly downloaded application. Specifically, the priority determination unit 12 searches the part extracted from the priority table of the downloaded application in step b13, for example, in order from the highest priority value, for the same genre as the newly downloaded application. It is determined whether there is an unused priority value among the priority values.

  If it is determined in step b18 that there is an unused priority value among the priority values for the same genre as that of the newly downloaded application, the process proceeds to step b20 and the priority for the same genre as that of the newly downloaded application is determined. If it is determined that there is no unused priority value among the values, the process proceeds to step b19.

  In step b19, the priority determination unit 22 sets the lowest value of the priority values for the same genre as the new download application as the priority value of the new download application.

  In step b20, the priority determination unit 22 sets one of the unused priority values among the priority values for the same genre as the new download application as the priority value of the new download application. Specifically, the priority determination unit 22 sets the highest priority value among the unused priority values as the priority value of the newly downloaded application. For example, the priority determination unit 22 may use the lowest priority value among the unused priority values as the priority value of the newly downloaded application.

  In step b21, the priority determining unit 22 gives the priority value determined in step b11, step b19, or step b20 to the priority information creating unit 21. In step b22, the priority information creating unit 21 creates priority information representing the priority value from the priority value given from the priority determining unit 22 in step b21.

  In step b23, the priority information creating unit 21 transmits the priority information created in step b22 from the server side communication interface unit 26 to the in-vehicle terminal 30 via the communication network 27. After the process of step b23 is completed, the process returns to step b1.

  As described above, according to the server device 20 of the present embodiment, when the server-side communication interface unit 26 receives the priority determination request message from the in-vehicle terminal 30, the priority of the new download application is determined by the priority determination device 2. Is done. Priority information representing the determined priority is created by the priority information creating unit 21 and transmitted from the server side communication interface unit 26 to the in-vehicle terminal 30.

  Thus, in the in-vehicle terminal 30, the new download application can be operated together with the existing native application and downloaded application without impairing the function of the newly introduced new download application. Can be determined by the server device 20. Therefore, in the in-vehicle terminal 30, it is possible to operate the new download application together with the native application and the downloaded application that are existing applications without impairing the function of the newly introduced new download application.

  The in-vehicle information system 10 includes the server device 20 and the in-vehicle terminal 30 as described above. In the in-vehicle information system 10, when the priority determination request message is transmitted from the terminal-side communication interface unit 34 of the in-vehicle terminal 30 and received by the server-side communication interface unit 26 of the server device 20, a new download is performed by the priority determination device 2. App priority is determined. The priority information indicating the determined priority is created by the priority information creating unit 21 and transmitted from the server-side communication interface unit 26 to the in-vehicle terminal 30.

  When the terminal-side communication interface unit 34 receives priority information from the server device 20, the control unit 31 of the in-vehicle terminal 30 causes a new download application to be executed based on the received priority information. Therefore, the in-vehicle terminal 30 can operate the new download app together with the native app and the downloaded app that are existing apps without impairing the function of the newly introduced new download app.

  In the present embodiment, the priority of the new download application is determined according to the processing procedure shown in the flowcharts of FIGS. 6 to 8 described above. The processing procedure of the priority determination process for determining the priority of the new download application is as follows: However, the present invention is not limited to this, and other processing procedures may be used.

  FIGS. 9-11 is a flowchart which shows the other process sequence regarding the priority determination process of the priority determination apparatus 2 in the 2nd Embodiment of this invention. Each process of the flowcharts illustrated in FIGS. 9 to 11 is executed by the priority information creation unit 21, the priority determination unit 22, and the terminal information acquisition unit 24. 9 to 11, similarly to the above-described FIGS. 2 to 4 and FIGS. 6 to 8, assume a new download application as an undetermined application, and show processing procedures when determining the priority of the new download application. .

  Since the process of the flowchart shown in FIG. 9 is the same as the process of the flowchart shown in FIG. 6 described above, the same steps are denoted by the same step numbers and the description thereof is omitted. The flowchart showing the processing of the priority determination device 2 in FIGS. 9 to 11 is started when a new download application is downloaded, and the process proceeds to step b1 in FIG.

  Similarly to the case shown in FIG. 9, the processing from step b1 to step b8 is sequentially executed. After the process of step b8 in FIG. 9 is completed, the process proceeds to step c1 in FIG.

  In step c1 of FIG. 10, the priority determination unit 22 determines whether or not the download source of the new download application can be trusted based on the profile information of the new download application acquired in step b8, as in step b9 described above. Judging. In step c1, when it is determined that the download source of the new download application is reliable, the process proceeds to step c2, and when it is determined that the download source of the new download application is not reliable, the process proceeds to step c3.

  In step c2, the priority determining unit 22 acquires a priority candidate value from the profile information of the newly downloaded application acquired in step b2. Table 9 shows an example of priority candidate values for a new download application. As shown in Table 9, for example, the new download application is an application with the application name “Internet navigation”, and the priority candidate value of this new download application is “3”. When the process of step c2 ends, the process proceeds to step c4.

  In step c3, the priority determination unit 22 determines the lowest priority value among the values prepared in advance as the priority value as the priority value of the new download application. After the process of step c3 is complete | finished, it transfers to step c13 of FIG.

  In step c4, the priority determination unit 22 searches the 3rd application DB 23 for all the applications in the priority table of the downloaded application acquired in step b2, and acquires priority candidate values for each application. In step c5, the priority determination unit 22 creates a priority candidate value table for downloaded applications from the priority candidate values acquired in step c4.

  In step c6, the priority determination unit 22 combines the priority table of the native application given from the terminal information acquisition unit 24 in step b6 and the priority candidate value table of the downloaded application created in step c5, Create a priority value / priority candidate value table. An example of the priority value / priority candidate value table is shown in Table 10.

  Among the apps A to E shown in Table 10, for example, apps A, B, and C are native apps, and apps D and E are downloaded apps. In Table 10, numerical values shown in parentheses are priority values when the app is a native app, and are priority candidate values when the app is a downloaded app.

  In step c7, the priority determination unit 22 adds the priority candidate value of the new download application acquired in step c2 to the priority value / priority candidate value table created in step c6. In step c8, the priority determination unit 22 sorts the priority value / priority candidate value table in ascending order of priority values or priority candidate values.

  An example of the priority value / priority candidate value table after sorting is shown in Table 11. Table 11 corresponds to a combination of Table 9 and Table 10 described above. In Table 11, numerical values shown in parentheses are priority values when the app is a native app, and are priority values and priority candidate values when the app is a newly downloaded app or a downloaded app. . After the process of step c8 is complete | finished, it transfers to step c9 of FIG.

  Next, in step c9 of FIG. 11, the priority determination unit 22 determines whether or not the priority candidate value of the newly downloaded application overlaps with the priority value of another application in the sorting result of step c8 of FIG. to decide. Here, when the other application is a downloaded application, in step c9, the priority determination unit 22 determines whether the priority candidate value of the newly downloaded application overlaps with the priority candidate value of the other application. Determine whether. In the following description, unless otherwise specified, “priority value of other application” including “priority candidate value of other application” is referred to.

  If it is determined in step c9 that the priority candidate value of the newly downloaded application is overlapped with the priority value of another application, the process proceeds to step c10, where the priority candidate value of the newly downloaded application is the other application's priority value. If it is determined that the priority value does not overlap, the process proceeds to step c12.

  For example, when the sorting result at step c8 is as shown in Table 11 above, the priority candidate value “3” of the “Internet navigation” that is the new download application is the priority value “3” of the application C. Overlap. Therefore, in step c9, it is determined that the priority candidate value of the newly downloaded application overlaps with the priority value of the other application, and the process proceeds to step c10.

  In step c10, the priority determination unit 22 acquires a priority value or a priority candidate value of an application one level lower than the newly downloaded application in the sorted priority value / priority candidate value table. For example, in the example shown in Table 11 above, the next application of “Internet Navi”, which is a newly downloaded application, is application D. Therefore, in step c10, the priority candidate value “4” of application D is acquired. .

  In step c11, the priority determination unit 22 obtains an average value of the priority value or priority candidate value acquired in step c10 and the priority candidate value of the new download application acquired in step c2, and calculates the average value thus obtained. Is determined as the priority value of the newly downloaded application. An example of the determined priority value of the newly downloaded application is shown in Table 12. The priority values shown in Table 12 are the priority values of the new download application determined in the examples shown in Tables 9 to 11 described above.

  For example, in the examples shown in Table 9 to Table 11 above, “3” is acquired as the priority candidate value of the newly downloaded application in step c2, and the priority candidate value “4” of application D is acquired in step c10. Is done. Therefore, in step c11, as an average value of the priority candidate value “4” of the application D and the priority candidate value “3” of the newly downloaded application, (4 + 3) /2=3.5 to “3.5”. Is required.

  The obtained average value “3.5” is determined as the priority value of “Internet navigation” which is a new download application as shown in Table 12. After the process of step c11 is complete | finished, it transfers to step c13.

  In step c12, the priority determination unit 22 determines the priority candidate value of the new download application acquired in step c2 as the priority value of the new download application. After the process of step c12 is complete | finished, it transfers to step c13.

  In step c13, the priority determination unit 22 rewrites the priority value of the newly downloaded application in the priority value / priority candidate value table after sorting in step c8 to the value determined this time. Specifically, the priority determination unit 22 sets the priority value of the newly downloaded application included in the sorted priority value / priority candidate value table in step c3, step c11, or step c12. Rewrite to the value determined for the degree value. For example, in the priority value / priority candidate value table shown in Table 11, the Internet navigation priority candidate value is rewritten to the value determined as the priority value of the newly downloaded application in step c3, step c11 or step c12. It is done.

  In step c14, the priority determination unit 22 deletes the part related to the native application from the priority value / priority candidate value table rewritten in step c13, and creates a new 3rd application priority table. In step c15, the priority determination unit 22 provides the priority information creation unit 21 with the new 3rd application priority table created in step c14.

  In step c16, the priority information creation unit 21 creates priority information representing the 3rd application priority table from the new 3rd application priority table given from the priority determination unit 12 in step c15.

  In step c17, the priority information creating unit 21 transmits the priority information created in step c16 from the server side communication interface unit 26 to the in-vehicle terminal 30 via the communication network 27. Specifically, the priority information creation unit 21 gives the priority information created in step c16 to the server-side communication interface unit 26. The server-side communication interface unit 26 transmits the priority information given from the priority information creation unit 21 to the in-vehicle terminal 30 via the communication network 27. After the process of step c17 is completed, the process returns to step b1.

  The in-vehicle terminal 30 receives the priority information transmitted from the server side communication interface unit 26 in step c <b> 17 by the terminal side communication interface unit 34. The control unit 31 registers the priority information received by the terminal-side communication interface unit 34, specifically, a new 3rd application priority table represented by the received priority information in the 3rd application priority DB 33.

  As described above, in other processing procedures of the priority determination process illustrated in FIGS. 9 to 11, it is determined in step c <b> 9 that the priority candidate value of the newly downloaded application overlaps with the priority value of the other application. If so, the process proceeds to step c10. In step c10 to step c11, the priority value of the newly downloaded application and the priority value or priority candidate value of the next application after the new downloaded application in the sorted priority value / priority candidate value table The average value is determined as the priority value of the newly downloaded application.

  By determining the priority value in this way, the priority value of the newly downloaded application is determined to be closer to the priority candidate value when the priority value of the newly downloaded application is already used and cannot be used. can do. Therefore, it becomes possible to execute a new download application with a more ideal priority.

  In other processing procedures of the priority determination process shown in the flowcharts of FIGS. 9 to 11, the priority determination device 2 determines the priority of the new download application without using the genre information. Instead, the priority of the new download application may be determined using the genre information in the same manner as the processing procedures shown in the flowcharts of FIGS.

  In this case, in step c4, the priority candidate value of each application is acquired for the application of the same genre as the newly downloaded application in the priority table of the downloaded application acquired in step b2. In step c5, the priority candidate is acquired. A value table is created. Similarly, for the priority table of the native application, the application part of the same genre as the newly downloaded application is used.

  Table 13 shows an example of the priority value of the newly downloaded application determined in step c11 in this case. As shown in Table 13, the priority value of the newly downloaded application determined in step c11 in this case is obtained in association with the genre information.

  In step c13, the priority value of the newly downloaded application included in the sorted priority value / priority candidate value table is rewritten to the value determined as the priority value of the new downloaded application in step c11, for example. An example of the rewritten priority value / priority candidate value table is shown in Table 14. As shown in Table 14, the priority value / priority candidate value table is obtained in association with the genre information of the newly downloaded application.

  In the present embodiment described above, the server device 20 determines the priority of undecided apps such as a new download app based on the priority information of the native app and the 3rd app. Without being limited thereto, the server device 20 may determine the priority of the undetermined application based on the operation status of the undetermined application. In this case, the server device 20 is provided with an emulator capable of reproducing the functions of the 3rd application monitoring unit 17, the 3rd application execution unit 18 and the API-genre DB 19 shown in FIG. What is necessary is just to determine a priority based on the operation | movement condition at that time.

<Third Embodiment>
FIG. 12 is a block diagram showing a configuration of the in-vehicle information terminal device 3 according to the third embodiment of the present invention. The in-vehicle information terminal device 3 includes the priority determination device 1, a control unit 41, and a communication interface unit 42. The priority determining apparatus 1 in the present embodiment has the same configuration as the priority determining apparatus 1 in the first embodiment shown in FIG. Therefore, the same components as those of the priority determination device 1 of the first embodiment are denoted by the same reference numerals, and the description thereof is omitted.

  The control unit 41 is connected to the communication interface unit 42 and the priority determination unit 12 of the priority determination device 1 that configure the in-vehicle information terminal device (hereinafter sometimes simply referred to as “in-vehicle terminal”) 3. The control unit 41 includes, for example, a CPU and a memory such as a writable RAM. The memory stores a control program for the in-vehicle terminal 3. The control unit 41 comprehensively controls the communication interface unit 42 and the priority determination device 1 configuring the in-vehicle terminal 3 according to a control program stored in the memory. The function of the communication interface unit 42 is realized by the CPU executing the control program stored in the memory.

  The control unit 41 is connected to an input device 51 and a display device 52 provided outside the in-vehicle terminal 3. The communication interface unit 42 is connected to an in-vehicle local area network (abbreviation: LAN) 53 provided outside the in-vehicle terminal 3. The in-vehicle terminal 3, the input device 51, the display device 52, and the in-vehicle LAN 53 are provided in a vehicle, for example, an automobile.

  Information relating to the vehicle (hereinafter sometimes referred to as “vehicle information”) is input to the control unit 41 from the in-vehicle LAN 53 via the communication interface unit 42. The vehicle information includes, for example, position information acquired by a GPS sensor and vehicle speed information indicating the speed of the vehicle. The vehicle speed information is, for example, a vehicle speed pulse.

  The input device 51 includes, for example, a touch panel operated by a user, a remote controller, or a voice input device having a voice recognition function for recognizing a user's voice instruction. The input device 51 is configured to be operable by the user. The input device 51 generates an operation signal corresponding to the user's operation, and gives the generated operation signal to the control unit 41.

  The display device 52 is configured by a liquid crystal display, for example. The display device 52 performs display according to the display signal given from the control unit 41. For example, the control unit 41 generates a display signal corresponding to position information input from the in-vehicle LAN 53 and supplies the display signal to the display device 52. The display device 52 displays an image representing position information in accordance with the display signal given from the control unit 41.

  The priority determination apparatus 1 performs the priority determination process according to the same processing procedure as that shown in the flowcharts of FIGS. The control unit 41 causes the native app and the 3rd app to be executed based on the priority determined by the priority determination device 1.

  As described above, the priority determination device 1 determines the priority value of the new download application based on the genre information of the new download application. Thus, for example, when the 3rd application is a navigation application, the priority of the 3rd application can be set higher than that of the entertainment genre application and other genre applications.

  Therefore, when the navigation application is operating, it is possible to prevent the operation of other applications from being prioritized. Therefore, the operation of the other application causes the route guidance voice output by the navigation application and the display device 52 to It can be prevented that the image output operation is not performed. Accordingly, it is possible to prevent the user from losing the timing of, for example, right turn or left turn, and to prevent the fuel of the vehicle from being consumed more than necessary.

  As described above, the in-vehicle terminal 3 according to the present embodiment includes the priority determination device 1 according to the first embodiment described above. As described above, the priority determination apparatus 1 according to the first embodiment allows the newly downloaded application to be installed together with the existing native application and the downloaded application without impairing the functions of the newly downloaded application. The priority of the new download app can be determined so that it can be operated. Therefore, in the in-vehicle terminal 3 of the present embodiment, the new download application can be operated together with the existing native application and downloaded application without impairing the function of the newly introduced new download application.

  In each of the embodiments described above, the width of the priority value for each genre is all 10, but the width of the priority value may be changed for each genre. For example, the priority value of the “entertainment” genre may be 31 to 60, and the priority value of the “other” genre may be 61 to 100. By setting a wide range of priority values according to the number of available applications for each genre, flexible application control can be performed.

  In the embodiment described above, the number of priority values is not fixed, and the priority value offset by genre and the width of the priority value in the genre may be dynamically changed.

  In each of the embodiments described above, the profile information of an undetermined application such as a new download application includes a priority candidate value, but may not include a priority candidate value. When the profile information of the undetermined application does not include the priority candidate value, the steps related to the priority candidate value in each flowchart described above are not performed.

  The present invention can be freely combined with each embodiment within the scope of the invention. In addition, any component in each embodiment can be changed or omitted as appropriate.
