(Knowledge underlying the present disclosure)
In recent years, when a mobile device is connected to a cloud via a user terminal carried by a user of the mobile device so as to be able to communicate with the cloud, and the version of the application package in the battery is updated on the cloud side, the updated latest version of the application package is sent to the user. A technique is being studied for transmitting to a mobile object via a terminal and installing the latest version of the application package in the battery control board of the mobile object.

However, the processor of the battery control board generally does not have the specs to parallelize the operations that should be performed during the installation operation. Therefore, if the processor of the battery starts installing the application package while the battery of the mobile device is being used, the original operation of the processor may be restricted, and the use of the mobile device by the user may be hindered.

Here, it is conceivable that the edge side including the mobile unit and the user terminal predicts the time when the mobile unit is not used and installs the application package in the processor, but the edge side carries out this prediction. Adopting this aspect is not realistic because it does not have enough resources to do so.

The present disclosure has been made to solve such problems, and aims to provide a technique for preventing the user's use of a mobile device from being hindered by installation of an application package using a battery.

A method according to one aspect of the present disclosure is a method in a terminal device communicably connected to a server via a first communication channel and communicatively connected to a mobile object having a battery via a second communication channel. the processor of the terminal device acquires usage data of the battery by the mobile body from the mobile body and transmits the data to the server, and the frequency of usage of the battery by the mobile body calculated based on the usage data obtains from the server time information indicating the time when is equal to or lower than the reference frequency, obtains the application package of the battery from the server, transmits the application package to the mobile body, and executes the application at the time indicated by the time information An installation instruction is sent to the mobile object for the processor of the battery to install the package.

According to this configuration, the first version information of the installed application package is obtained from the mobile device, and the second version information of the latest application package is obtained from the server. is obtained from the server. Therefore, even if the installed application package is the latest version, the terminal device is prevented from acquiring the latest version of the application package from the server, and unnecessary communication between the server and the terminal device is prevented. can.

The vehicle communication device 32 transmits operation data to the first server 1 via the terminal device 2 at predetermined sampling intervals.

The above is the configuration of the information processing system. Next, the operation of the information processing system according to this embodiment will be described. FIG. 6 is a sequence diagram showing an example of processing when operation data is transmitted. It is assumed that the vehicle communication device 32 and the terminal device 2 have already been paired before this sequence is started.

In step S<b>101 , the battery management device 33 generates operation data and transmits the generated operation data to the vehicle communication device 32 via the communication path 6 .

In step S<b>102 , the vehicle communication device 32 receives the operation data and transmits it to the terminal device 2 . In step S<b>103 , the terminal device 2 transmits operation data to the first server 1 . At step S104, the communication circuit 11 of the first server 1 receives the operation data.

In step S<b>105 , the acquisition unit 121 of the first server 1 saves the operation data in the history database 131 . In step S106, the calculation unit 122 of the first server 1 determines whether or not the current time is the predetermined time. If the current time is the predetermined time (YES in step S106), the calculation unit 122 calculates time information (step S107). On the other hand, if the current time is not the predetermined time (NO in step S106), the calculation unit 122 skips steps S107 and S108. Here, the predetermined time is, for example, a certain time in one day (for example, 0:00). As a result, time information is calculated for each day. Note that a period other than one day (for example, 12 hours, 2 days, or 1 week) may be adopted as the calculation period of the time information.

Details of calculation of time information are as follows. In the following description, one battery 31 (hereinafter referred to as "target battery") will be taken as an example. First, the calculation unit 122 acquires operation data of the target battery for a certain period in the past from the history database 131 . Next, the calculation unit 122 divides the acquired operation data into units of one day. As a result, the acquired operation data is divided into daily operation data sets. Next, the calculation unit 122 divides the day into hourly time slots for each operation data set, and calculates the number of times the subject battery has been used in each time slot. For example, this time is calculated as one time between 1:00 and 0 times between 2:00. For example, when the state in which the discharge current value is equal to or greater than the threshold continues for a certain period of time or longer, the calculation unit 122 counts the number of times as one time.

Next, the calculation unit 122 obtains the average value of the number of times in each time period during the past fixed period as the frequency. At this time, the calculation unit 122 may calculate the frequency by assigning a lower weight value to the number of times in each time period as the number of times in the past increases. Next, the calculation unit 122 extracts time periods in which the frequency is equal to or less than the reference frequency for each time period. Next, the calculation unit 122 performs a process of connecting consecutive time slots in the extracted time slots. Next, the calculation unit 122 identifies the time period with the longest length among the time periods after performing the connecting process. Next, the calculation unit 122 sets a predetermined time (for example, the beginning time or the middle time) within the identified time period as the low-frequency use time, and calculates information indicating this low-frequency use as time information. The calculation unit 122 applies such processing to each battery 31 to calculate the time information of each battery.

Although one low-frequency use time is calculated here, a plurality of low-frequency use times may be calculated. For example, the calculation unit 122 ranks the time periods with frequency equal to or lower than the reference frequency in descending order of frequency, extracts a plurality of time periods from the top, and converts the representative time of each of the extracted plurality of time periods to the low frequency use time. may be calculated as In this case, the calculation unit 122 may include the calculated multiple low-frequency use times in the time information.

In step S<b>108 , the calculation unit 122 stores the low-frequency use time indicated by the calculated time information in the time database 133 . As a result, the low-frequency use time of each battery 31 stored in the time database 133 is updated on a daily basis. Note that when a plurality of infrequently used times are calculated for the target battery, the plurality of infrequently used times are registered in the field of the infrequently used time of the target battery in the time database 133 .

Operation data is accumulated in the history database 131 of the first server 1 by repeating the above process at a predetermined sampling period.

FIG. 7 is a sequence diagram showing an example of processing when time information is transmitted from the first server 1 to the terminal device 2. As shown in FIG. It is assumed that the vehicle communication device 32 and the terminal device 2 have already been paired before this sequence is started.

In step S<b>201 , the second acquisition unit 222 of the terminal device 2 transmits a package information acquisition request to the vehicle communication device 32 using the communication circuit 21 . In step S<b>202 , the vehicle communication device 32 receives the acquisition request and transmits it to the battery management device 33 . In step S<b>203 , the battery management device 33 receives the acquisition request and acquires the package information from the memory 333 .

In step S<b>204 , the battery management device 33 transmits the package information to the vehicle communication device 32 . In step S<b>205 , the vehicle communication device 32 receives the package information and transmits the received package information to the terminal device 2 . In step S<b>206 , the communication circuit 21 of the terminal device 2 receives the package information, and the second acquisition unit 222 of the terminal device 2 transmits the authentication request and package inquiry to the second server 4 using the communication circuit 21 . The authentication request is information for the terminal device 2 to have the first server 1 permit the transmission of the package. The authentication request includes the battery ID of the target battery. A package inquiry is information for inquiring about the latest version of the target package. The target package is the package used by the target battery. The package inquiry includes package information of the target battery. Version information included in the package information is an example of first version information.

In step S<b>207 , the second server 4 receives the authentication request and package inquiry and transmits them to the first server 1 .

In step S208, the communication circuit 21 of the first server 1 receives the authentication request and package inquiry.

In step S209, the package management unit 123 of the first server 1 performs authentication processing. Here, if the battery ID included in the authentication request is registered in the time database 133, the package management unit 123 permits the authentication. Authentication should be disallowed. Here, it is assumed that the authentication is permitted.

In step S210, the package management unit 123 of the first server 1 stores version information (an example of second version information) indicating the latest version of the target package using the version name of the package information included in the package inquiry as a key in the package database. 132.

In step S211, the package management unit 123 of the first server 1 acquires the time information of the target battery from the time database 133 using the battery ID of the target battery as a key.

In step S<b>212 , the package management unit 123 of the first server 1 transmits the authentication response and time information to the second server 4 using the communication circuit 11 . The authentication response is information that permits authentication. The authentication response contains token information required when the terminal device 2 communicates with the first server 1 .

In step S<b>213 , the second server 4 receives the authentication response and time information and transmits them to the terminal device 2 .

In step S214, the communication circuit 21 of the terminal device 2 receives the authentication response and the time information, and the second acquiring section 222 of the terminal device 2 acquires the authentication response and the time information. In step S<b>215 , the second acquisition unit 222 of the terminal device 2 stores the time information in the memory 23 .

As described above, the terminal device 2 obtains the time information of the target battery from the first server 1 .
