<1. Information processing method>
FIG. 1 is a diagram for explaining an information processing method according to an embodiment of the present invention, and the information processing method is executed by the information processing device 1.

The information processing device 1 shown in FIG. 1 includes a service providing unit capable of providing a plurality of types of services S in the vehicle C. Examples of the type of service S provided by the information processing device 1 include telephone service Sa, e-mail notification service Sb, navigation service Sc, traffic information providing service Sd, weather information providing service Se, and voice search service Sf. The service S is not limited to the information providing service.

The information processing device 1 has a load generated by the driver D due to the operation of the vehicle C (hereinafter referred to as a driving load LD) and a load generated by the service S provided by the service providing unit (hereinafter referred to as a service load). Control the provision of service S based on (described as LS).

As shown in FIG. 1A, the information processing device 1 according to the embodiment determines the driving load LD of the driver D. The determination of the driving load LD is performed based on, for example, the movement of the line of sight of the driver D. For example, the information processing device 1 can determine that the larger the amount of movement of the line of sight of the driver D, the larger the driving load LD of the driver D. Further, the information processing device 1 determines that the longer the time the driver D's line of sight is directed to a predetermined target (for example, a rear-view mirror or the side mirror) and the higher the frequency, the greater the driving load LD of the driver D. can do.

The information processing device 1 replaces or adds to the movement of the line of sight of the driver D, for example, at least one of the driving operation state of the driver D, the driving environment of the vehicle C, and the driving state of the vehicle C. Based on this, the driving load LD of the driver D can also be determined.

As shown in FIG. 1A, when the information processing device 1 occurs as a service to be provided by the first service S1 (for example, a traffic information providing service), the load generated on the driver D by the first service S1 Determine a service load LS. The service load LS is different for each type of service S, for example.

The information processing device 1 controls the provision of the first service S1 based on the total value of the driver D's driving load LD and the service load LS (hereinafter, referred to as the total load value LT). For example, the information processing device 1 determines whether or not the total load value LT exceeds the load allowable value LM of the driver D, and controls the provision of the first service S1 based on the determination result. In the example shown in FIG. 1A, since the total load value LT does not exceed the load allowable value LM, the information processing device 1 provides the first service S1 to the driver D.

After that, as shown in FIG. 1 (b), when the second service S2 (for example, an e-mail notification service) occurs as the service S to be provided, the service load which is the load caused to the driver D by the second service S2. Determine the LS. Then, the information processing device 1 controls the provision of the second service S2 based on the total load value LT, which is the total value of the driver D's driving load LD and the service load LS.

As shown in FIG. 1 (b), the service load LS of the second service S2 is higher than the service load LS of the first service S1, and the total load value LT exceeds the load allowable value LM of the driver D. The information processing device 1 regulates the provision of the second service S2 to the driver D.

The information processing device 1 regulates the provision of the second service S2 to the driver D, for example, stopping the provision of the second service S2, changing the provision timing of the second service S2, and providing the contents of the second service S2. At least one of the change and the change of the method of providing the second service S2 is executed.

For example, the information processing apparatus 1 can set the provision timing of the second service S2 to be the timing when the total load value LT becomes lower than the load allowable value LM. As a result, it is possible to suppress the provision of the service S in a state where the total load value LT exceeds the load allowable value LM of the driver D, so that the service S can be suppressed while suppressing the influence on the driving operation of the driver D. Can be provided. Therefore, the service can be provided to the driver D more appropriately.

Further, the information processing apparatus 1 can reduce the content provided by the second service S2 (for example, the amount of information to be provided) so that the total load value LT does not exceed the load allowable value LM. For example, the information processing device 1 may not provide a part of the e-mail notification service Sb. This also makes it possible to suppress the provision of the service S in a state where the total load value LT exceeds the load allowable value LM of the driver D.

Further, the information processing apparatus 1 can change the method of providing the second service S2 so that the total load value LT does not exceed the load allowable value LM. For example, the notification of the e-mail notification service Sb can be changed from the auditory notification to the visual notification or the tactile notification, and this also provides the service S that exceeds the load tolerance LM of the driver D. It can be suppressed.

<2.7.3. Service load determination unit 32>
The service load determination unit 32 determines the service load LS, which is a load generated on the driver D by the service S provided by the service provision unit 30.

For example, when the service S to be provided by the service providing unit 30 occurs, the service load determining unit 32 is a driver generated by the service S to be provided based on the service load information stored in the service load information storage unit 22. The service load LS, which is the load of D, is determined.

Further, the service load determination unit 32 provides information indicating the type of service S (hereinafter referred to as service type) and the item of service S (hereinafter referred to as service item) to be provided by the service providing unit 30. It is assumed that it is obtained from the part 30.

When the service type is "e-mail notification service", the service load determination unit 32 determines that the service load LS is "100" if the service item is "new arrival notification", and the service item is "text". If it is "read aloud", it is determined that the service load LS is "400".

Further, when the service type is "telephone service", the service load determination unit 32 determines that the service load LS is "100" if the service item is "incoming call notification", and the service item is "call". If, it is determined that the service load LS is “400”.

The service load information stored in the service load information storage unit 22 may be information in which a load having a different value for each user is stored in association with the service S. That is, the service load information may be information in which the service S information (service type and service item) and the service load LS information are associated with each user.

In this case, the service load determination unit 32 uses the service load information stored in the service load information storage unit 22 to include information about the user U corresponding to the current driver D (for example, the user U1 is the current driver). If it is D, the service load LS is determined based on the service load LS information corresponding to the user U1).

As a result, the service load LS according to the driver D can be determined more accurately. The service load determination unit 32 can identify the current driver D based on the captured image output from the image pickup unit 11, for example, and the authentication information (for example, the user) input to the input unit 14. The current driver D can be identified based on the ID, password, etc.).

Further, as shown in FIG. 5, the service load LS is not limited to the one corresponding to the service type and the service item, and may be associated only with the service type, and further, the service provision time (for example, to the driver D). It may be changed according to the time for notifying the information) and the amount of service provided.

For example, the service load determination unit 32 can increase the service load LS as the service provision time is longer, even for the same service. Further, the service load determination unit 32 can increase the service load LS according to the service provision time while the service S is being provided. As a result, the service load LS of the service S, which has a long service provision time, can be increased.

<2.7.4.4. Provided control unit 33>
The provision control unit 33 is based on the total load value LT, which is the total value of the driving load LD of the driver D determined by the driving load determination unit 31 and the service load LS determined by the service load determination unit 32. Controls the provision of the service S by the service providing unit 30.

The provision control unit 33 includes an overload determination unit 51 and a control processing unit 52. The overload determination unit 51 calculates the total load value LT, which is the total value of the driving load LD of the driver D and the service load LS determined by the service load determination unit 32.

The overload determination unit 51 acquires the load tolerance LM of the driver D from the load tolerance information storage unit 21. For example, when the load tolerance information stored in the load tolerance information storage unit 21 is in the state shown in FIG. 4 and the user U1 is the driver D, the overload determination unit 51 determines that the load tolerance LM is ". It is determined that it is "1000". Further, when the user U3 is the driver D, the overload determination unit 51 determines that the load allowable value LM is “700”.

The overload determination unit 51 can identify the current driver D based on the captured image output from the image pickup unit 11, for example, and the authentication information (for example, the user) input to the input unit 14. The current driver D can be identified based on the ID, password, etc.).

The overload determination unit 51 determines whether or not the total load value LT of the driver D exceeds the load allowable value LM of the driver D. For example, when the load tolerance information stored in the load tolerance information storage unit 21 is in the state shown in FIG. 4 and the user U1 is the driver D, the overload determination unit 51 determines the operating load of the user U1. It is determined whether or not the total load value LT, which is the sum of the LD and the service load LS, exceeds "1000".

When the control processing unit 52 determines that the total load value LT of the driver D does not exceed the load allowable value LM of the driver D, the control processing unit 52 controls the service providing unit 30 and performs the task of the service S to be provided by the service providing unit 30. To execute. As a result, the service S is provided from the service providing unit 30 to the driver D.

When the control processing unit 52 determines that the total load value LT of the driver D exceeds the load allowable value LM of the driver D, the control processing unit 52 controls the service providing unit 30 and regulates the provision of the service S by the service providing unit 30. The control processing unit 52 regulates the provision of the service S by the service providing unit 30, for example, stopping the provision of the service S, changing the provision timing of the service S, limiting the content of the service S, and providing the service S. This can be done by performing at least one of the method changes.

For example, in the control processing unit 52, while the service S is being provided by the service providing unit 30, the driving load LD of the driver D becomes high, and the total load value LT of the driver D is the load tolerance of the driver D. When the value LM is exceeded, a service stop request is made to the service providing unit 30. As a result, the service S provided by the service providing unit 30 is stopped.

After that, when the total load value LT of the driver D is less than the load allowable value LM of the driver D, the control processing unit 52 makes a service restart request to the service providing unit 30. As a result, the service providing unit 30 restarts the execution of the stopped service S task. When the service providing unit 30 receives a service restart request, the service providing unit 30 can also provide the stopped service S from the beginning.

Further, when the service S to be provided by the service providing unit 30 occurs in a state where the total load value LT of the driver D exceeds the load allowable value LM of the driver D, the control processing unit 52 services the service stop request. It can be performed to the providing unit 30. As a result, it is possible to prevent the service S from being provided to the driver D in a state where the total load value LT of the driver D exceeds the load allowable value LM of the driver D.

After that, when the total load value LT of the driver D is less than the load allowable value LM of the driver D, the control processing unit 52 makes a service start request to the service providing unit 30. As a result, the service S provided by the service providing unit 30 is started. In this way, the control processing unit 52 can provide the service S while suppressing the influence on the driving operation of the driver D by changing the provision timing of the service S.

The control processing unit 52 determines that the total load value LT of the driver D falls below a predetermined value or more lower than the load allowable value LM of the driver D, or the state of falling below the predetermined value continues for a predetermined period. It is also possible to make a service restart request or a service start request to the service providing unit 30. As a result, it is possible to prevent the service S from being repeatedly stopped and restarted when the total load value LT of the driver D fluctuates in the vicinity of the load allowable value LM of the driver D.

Further, the control processing unit 52 can limit the content provided by the service S so that the total load value LT of the driver D does not exceed the load allowable value LM of the driver D. For example, when the control processing unit 52 provides the e-mail notification service Sb by sequentially performing new arrival notification and reading the text, the total load value LT of the driver D does not exceed the load allowable value LM of the driver D. As you can see, you can only notify new arrivals.

Further, when the telephone service Sa is provided by performing the incoming call notification and the call connection, the control processing unit 52 receives an incoming call so that the total load value LT of the driver D does not exceed the load allowable value LM of the driver D. Only notifications can be made.

Further, for example, when the service S is provided by both the speaker 12 and the display 13, the control processing unit 52 prevents the total load value LT of the driver D from exceeding the load allowable value LM of the driver D. The service providing unit 30 can be controlled so that the service S is provided by only one of the display 13 and the display 13. By changing the method of providing the service S in this way, the load on the driver D can be reduced, and the service S can be provided while suppressing the influence on the driving operation of the driver D.

Further, even if the control processing unit 52 limits the content provided by the service S or changes the method of providing the service S, the total load value LT of the driver D does not fall below the load allowable value LM of the driver D. In that case, the provision of the service S can be stopped or the provision timing can be changed.

Here, an example of information processing by the control unit 16 will be specifically described with reference to FIGS. 6 and 7. FIG. 6 is a diagram showing an example of the relationship between the change in the traveling position of the vehicle C and the task to be newly processed.

As shown in FIG. 6, it is assumed that the traveling position of the vehicle C changes in the order of positions P1, P2, P3, P4, P5, P6, and P7, and the service S to be processed occurs at the positions P2 and P4. Further, it is assumed that the driver D turns on the blinker for a right turn while the vehicle C moves from the position P3 to the position P4, and then the vehicle C becomes the position P6 and the blinker is turned off.

In this case, the task execution timing, the display content of the display 13, and the audio content output from the speaker 12 are controlled by the control unit 16, for example, as shown in FIG. FIG. 7 is a diagram showing an example of a task to be newly processed, a task execution timing, a display content of the display 13, and an audio content output from the speaker 12.

For example, when the position of the vehicle C is the position P1, there is no task to be processed (the task of the service S to be provided), and the control unit 16 displays the state of the driver D's driving load LD on the display screen 80 of the display 13. The image 82 showing the above is displayed. A map image 81 including the position where the vehicle C is currently traveling is displayed on the display screen 80 shown in FIG. 7, and the image 82 is arranged on the map image 81.

When the position of the vehicle C moves to the position P2, task 1 is determined as a new task to be processed. At this time, since the total load value LT (= operating load LD + service load LS) does not exceed the load allowable value LM, the control unit 16 executes the task 1 without limitation. As a result, the service S executed in task 1 is provided to the driver D.

The service S according to the task 1 is, for example, the e-mail notification service Sb, and the control unit 16 outputs, for example, a voice such as "A message from Mr. XXX has been received. Do you want to read it aloud?" From the speaker 12. The control unit 16 displays on the display screen 80 of the display 13 an image 83 indicating that a new mail has been received, in addition to an image 82 showing the state of the driving load LD of the driver D.

After that, when the driver D turns on the blinker and tries to drive a right turn, the driving load LD becomes high and the total load value LT exceeds the load allowable value LM. In this state, the task 2 is determined to be a new processing target, so the control unit 16 does not execute the task 2. As a result, the provision of the service S executed in the task 2 to the driver D is restricted.

At the position P6 where the right turn run is completed, the driving load LD becomes low, and the total load value LT becomes equal to or less than the load allowable value LM. Therefore, the control unit 16 starts executing the task 2. The service S according to the task 2 is, for example, the e-mail notification service Sb, and the control unit 16 outputs, for example, a voice such as "A message from Mr. YYY has been received. Do you want to read it aloud?" From the speaker 12. As a result, the service S executed in task 2 is provided to the driver D.

<3. Information processing device 1 processing>
Next, the process executed by the control unit 16 of the information processing apparatus 1 will be described with reference to FIG. FIG. 8 is a flowchart showing a processing procedure executed by the control unit 16 of the information processing apparatus 1, and the processing procedure is repeatedly executed by the control unit 16.

As shown in FIG. 8, the control unit 16 determines whether or not there is a service S to be provided, that is, whether or not there is a task to be processed (step S10). When it is determined that the task to be processed exists (step S10; Yes), the control unit 16 determines the driving load LD of the driver D (step S11), and the driver generated by the service S corresponding to the task to be processed The service load LS, which is the load of D, is determined (step S12).

Next, the control unit 16 calculates the total load value LT, which is the total value of the driving load LD and the service load LS (step S13), and further acquires the load allowable value LM of the driver D from the storage unit 15. (Step S14). Then, the control unit 16 determines whether or not the total load value LT exceeds the load allowable value LM (step S15).

When it is determined that the total load value LT exceeds the load allowable value LM (step S15; Yes), the control unit 16 limits the execution of the task to provide the service S corresponding to the task to be processed. Limit (step S16). In such processing, the control unit 16 performs at least one of, for example, stopping the execution of the task, changing the execution timing of the task (for example, postponing the execution), and changing the execution content of the task (execution of a part of the task). By executing it, the execution of the task can be restricted.

On the other hand, when it is determined that the total load value LT does not exceed the load allowable value LM (step S15; No), the control unit 16 executes the task and provides the service S corresponding to the task to be processed (step S15; No). S17).

In step S10, when it is determined that the task to be processed does not exist (step S10; No), when the processing in step S16 is completed, or when the processing in step S17 is completed, the control unit 16 shows FIG. The processing shown is finished.

<4. Modification example>
In the above-described embodiment, the control unit 16 of the information processing apparatus 1 provides the service S so that the total load value LT does not exceed the load allowable value LM, but the present invention is not limited to this example.

For example, even if the total load value LT exceeds the load allowable value LM during the provision of the service S, the control unit 16 continues to use the service S as long as the remaining time of the service S to be provided is within a predetermined time. Can be executed.

Further, even if the total load value LT exceeds the permissible load value LM during the provision of the service S, the control unit 16 does not exceed the predetermined value or more than the permissible load value LM. In addition, the provision of the service S can be stopped.

Further, when a plurality of services S to be provided occur at the same time, the control unit 16 sequentially provides the plurality of services S, but the order of provision can be performed based on the total load value LT. For example, when the services S to be provided are the first service S1 and the second service S2, the control unit 16 sets the total load value LT, which is the total value of the service load LS and the operation load LD of the first service S1, and The total load value LT, which is the total value of the service load LS of the second service S2 and the operating load LD, is calculated. Then, the control unit 16 can preferentially provide the service S having the higher total load value LT. Further, the control unit 16 can preferentially provide the service S having the lower total load value LT.

Further, when the control unit 16 continuously provides a plurality of services S, the load allowable value LM can be reduced each time the services S are provided. As a result, it is possible to suppress the continuation of the high load state of the driver D, and it is possible to provide the service S while suppressing the influence on the driving operation of the driver D.

Further, the control unit 16 can determine different service load LS even when the same service S is provided. For example, the control unit 16 can analyze the service S to be provided and determine the service load LS according to the analysis result. For example, when the service S to be provided is the e-mail notification service Sb, the control unit 16 morphologically analyzes the body of the received e-mail to extract a feature word, and applies a load to the driver D based on the feature word. It can be determined and determined as the service load LS. This makes it possible to increase the service load LS, for example, in the case of an e-mail notifying an urgent requirement.

<6. Effects, etc.>
As described above, the information processing device 1 according to the embodiment includes a service providing unit 30, an operating load determining unit 31, a service load determining unit 32, and a providing control unit 33. The service providing unit 30 provides one or more types of services S in the vehicle C. The driving load determination unit 31 determines the driving load LD of the driver D who is driving the vehicle C. The service load determination unit 32 determines the service load LS, which is a load generated on the driver D by the service S provided by the service provision unit 30. The provision control unit 33 controls the provision of the service S provided by the service provision unit 30 based on the total load value LT, which is the total value of the operation load LD and the service load LS. As a result, in addition to the driving load LD of the driver D, the load of the driver D caused by the provision of the service S can be taken into consideration. Therefore, the service S can be provided while suppressing the influence on the driving operation of the driver D. It can be carried out. Therefore, the service can be provided to the driver D more appropriately. That is, since the influence on the driver differs depending on the content of the service provided, it is determined whether or not the total value of the driver's driving load and the service load based on the service content exceeds the load allowable value. In particular, driving safety can be improved when providing services to drivers who are driving.

Further, the provision control unit 33 includes an overload determination unit 51 and a control processing unit 52. The overload determination unit 51 determines whether or not the total load value LT exceeds the load allowable value LM. The control processing unit 52 regulates the provision of the service S provided by the service providing unit 30 when the overload determining unit 51 determines that the total load value LT exceeds the load allowable value LM. As a result, it is possible to suppress the provision of the service S in a state where the total load value LT exceeds the load allowable value LM of the driver D, and the service S can be suppressed while suppressing the influence on the driving operation of the driver D. Can be offered.

Further, the control processing unit 52 regulates the provision of the service S provided by the service providing unit 30 at least among the suspension of the provision of the service S, the change of the provision timing of the service S, and the change of the provision content of the service S. Do it by doing one. As a result, the influence on the driving operation of the driver D can be suppressed, and the service can be provided to the driver D more appropriately. For example, if the total load value LT exceeds the allowable load value LM while the service S is being provided, the provision of the service S can be stopped, and the total load value LT exceeds the allowable load value LM before the service is provided. In that case, the provision timing of the service S can be changed (for example, postponed).

Further, the information processing device 1 includes a load tolerance information storage unit 21 (an example of a threshold storage unit) that stores the load tolerance LM for each user U in advance. The overload determination unit 51 acquires the load tolerance LM of the user U corresponding to the driver D from the load tolerance information storage unit 21, and determines whether or not the total load value LT exceeds the acquired load tolerance LM. judge. As a result, the load tolerance LM can be set according to the driver D, and even if the driver D is different, the service S is provided while appropriately suppressing the influence on the driving operation of the driver D. It can be performed.

Further, the information processing device 1 includes a service load information storage unit 22 (an example of the load information storage unit) that stores the information of the service S provided by the service providing unit 30 and the information of the service load LS in advance in association with each other. The service load determination unit 32 determines the service load LS generated in the driver D based on the information stored in the service load information storage unit 22. As a result, the service load LS can be easily determined, and the service S can be provided quickly.

Further, the service load information storage unit 22 stores the information of the service S provided by the service providing unit 30 and the information of the service load LS in association with each user U. The service load determination unit 32 determines the service load LS generated in the driver D based on the information of the user U corresponding to the driver D stored in the service load information storage unit 22. As a result, the service load LS according to the driver D can be appropriately determined.

Further, the driving load determination unit 31 includes a line-of-sight detection unit 41 and a determination processing unit 44. The line-of-sight detection unit 41 detects the movement of the line-of-sight of the driver D. The determination processing unit 44 determines the driving load LD of the driver D based on the movement of the driver D's line of sight detected by the line-of-sight detection unit 41. As described above, since the information processing device 1 determines the driving load LD of the driver D based on the movement of the line of sight of the driver D, the driving load LD of the driver D can be easily determined.
