Abstract

An in-vehicle apparatus in a vehicle executes a vehicular application software-program and communicates with an information center that manages a general attribute of the application software-program. The in-vehicle apparatus includes an information acquisition section and an information transmission section. The information acquisition section acquires a general-attribute information data while the application software-program is executed, the general-attribute information data being an information data on the general attribute of the application software-program. The information transmission section transmits the general-attribute information data acquired by the information acquisition section to the information center (i) when a period of time for which the application software-program is executed reaches a predetermined threshold period of time or (ii) when an execution count that is a count of executions of the application software-program reaches a predetermined threshold execution count.

Claims

1. An in-vehicle apparatus in a vehicle to execute a vehicular application software-program and communicate with an information center that manages a general attribute of the application software-program,

the in-vehicle apparatus comprising:

an information acquisition section that acquires a general-attribute information data while the application software-program is executed, the general-attribute information data being an information data on the general attribute of the application software-program; and

an information transmission section that transmits the general-attribute information data acquired by the information acquisition section to the information center (i) when a period of time for which the application software-program is executed reaches a predetermined threshold period of time or (ii) when an execution count that is a count of executions of the application software-program reaches a predetermined threshold execution count.

2. The in-vehicle apparatus according to claim 1, wherein

the general attribute includes a regulatory level that indicates a workload range of a driving of the vehicle, the workload range which permits execution of the application software-program during the driving;

and

the information acquisition section includes a frequency acquisition section to acquire an occurrence frequency that is a frequency of occurrences of a sudden driving operation performed while the application software-program is executed, the sudden driving operation including at least one of a sudden brake operation, a sudden accelerator operation, or a sudden steering-wheel operation.

3. The in-vehicle apparatus according to claim 1, wherein

the general attribute includes a regulatory level that indicates a workload range of a driving of the vehicle, the workload range which permits execution of the application software-program during the driving;

and

the information acquisition section includes an occurrence acquisition section to acquire an occurrence of a sudden driving operation performed while the application software-program is executed, the sudden driving operation including at least one of a sudden brake operation, a sudden accelerator operation, or a sudden steering-wheel operation.

4. The in-vehicle apparatus according to claim 1, wherein

the general attribute includes a regulatory level that indicates a workload range of a driving of the vehicle, the workload range which permits execution of the application software-program during the driving;

and

the information acquisition section includes a frequency acquisition section to acquire an occurrence frequency that is a frequency of occurrences of a user attention to display of execution of the application software-program performed while the application software-program is executed, the user attention including at least one of (i) user'"'"'s gaze directed at display of execution of the application software-program or (ii) user'"'"'s head-turning to display of execution of the application software-program.

5. The in-vehicle apparatus according to claim 1, wherein:

the general attribute includes a regulatory level that indicates a workload range of a driving of the vehicle, the workload range which permits execution of the application software-program during the driving; and

the information acquisition section includes an occurrence acquisition section to acquire an occurrence of a user attention to display of execution of the application software-program performed while the application software-program is executed, the user attention including at least one of (i) user'"'"'s gaze directed at display of execution of the application software-program or (ii) user'"'"'s head-turning to display of execution of the application software-program.

6. The in-vehicle apparatus according to claim 2, further comprising:

a management section that manages a user-specific regulatory level that is the regulatory level specific to a subject user who is any one of users that use the application software-program;

an identification section which identifies the subject user; and

a regulatory-level update section that updates the user-specific regulatory level specific to the subject user identified by the identification section when the occurrence frequency acquired by the frequency acquisition section satisfies an update condition.

7. The in-vehicle apparatus according to claim 6, wherein

the user-specific regulatory level includes a first level and a second level, the second level being stricter than the first level in respect of regulation of execution of the application software-program;

and

the regulatory-level update section updates the user-specific regulatory level from the first level into the second level when the occurrence frequency acquired by the frequency acquisition section becomes equal to or greater than a predetermined determination value in a first predetermined period of time, whereas

the regulatory-level update section updates the user-specific regulatory level from the second level into the first level when the occurrence frequency acquired by the frequency acquisition section becomes less than the predetermined determination value in a second predetermined period of time that is longer than the first predetermined period of time.

8. The in-vehicle apparatus according to claim 6, wherein:

the regulatory-level update section is enabled to update the user-specific regulatory level under a condition that the vehicle travels longer than a predetermined distance since the user-specific regulatory level was updated previously.

9. The in-vehicle apparatus according to claim 6, wherein:

the identification section identifies the subject user by recognizing at least one of (i) an identification of a key of the vehicle held by the subject user, (ii) a portable terminal held by the subject user, or (iii) a face of the subject user.

10. The in-vehicle apparatus according to claim 2, wherein:

the frequency acquisition section acquires the occurrence frequency that is the frequency of occurrences of the sudden brake operation performed while the application software-program is executed;

the occurrence of the sudden brake operation is detected

(i) when an amount of stepping onto a brake of the vehicle is greater than a first threshold value and, simultaneously, a displacement of a heart rate of the subject user is greater than a second threshold value, or

(ii) when a decreasing rate of a speed of the vehicle is greater than a third threshold value and, simultaneously, a displacement of the heart rate of the subject user is greater than a fourth threshold value.

11. The in-vehicle apparatus according to claim 1, wherein:

the general attribute includes a user layer of the application software-program; and

the information acquisition section includes a user information acquisition section that acquires a user information data to specify a user that uses the application software-program.

12. The in-vehicle apparatus according to claim 11, wherein:

the user information data includes at least one of an age, a gender, or a driving skill level.

13. The in-vehicle apparatus according to claim 1, wherein:

the information transmission section transmits anonymously the general-attribute information data acquired by the information acquisition section to the information center.
