Abstract

A center device includes: a consent request unit that is configured to make a consent request to a plurality of devices for data distribution to a vehicle; a consent determination unit that is configured to judge a consent response from each of the plurality of devices; a distribution control unit that is configured to control the data distribution to the vehicle according to a determination result by the consent determination unit; and a necessity determination unit that is configured to determine whether the consent request to the plurality of devices is needed before the consent request are made to the plurality of devices. The consent request unit is further configured to determine whether to make the consent request to the plurality of devices according to a determination result by the necessity determination unit.

First claim

What is claimed is:

1. A center device, comprising:
at least one processor; and
at least one memory storing computer program code, wherein
the computer program code, when executed by the at least one processor, causes the at least one processor to:
make a consent request to a plurality of devices for data distribution to a vehicle;
judge a consent response from each of the plurality of devices;
control the data distribution to the vehicle according to a determination result of the consent response; and
determine whether the consent request to the plurality of devices is needed before the consent request is made to the plurality of devices, wherein

the computer program code further causes the at least one processor:
determine whether to make the consent request to the plurality of devices according to a determination result of the consent request,
make the consent request to at least a first device and a second device among the plurality of devices upon determining that the consent request to the plurality of devices is needed, and
perform the data distribution to the vehicle upon determining that at least the consent response from the first device and the consent response from the second device indicate a permission.

2. The center device according to claim 1 , wherein
the computer program code further causes the at least one processor to:
make the consent request only to the first device among the plurality of devices upon determining that the consent request to the plurality of devices is not needed, and
perform the data distribution to the vehicle upon determining that the consent response from the first device indicates a permission.

3. A center device, comprising:
at least one processor; and
at least one memory storing computer program code, wherein
the computer program code, when executed by the at least one processor, causes the at least one processor to:
make a consent request to a plurality of devices for data distribution to a vehicle;

judge a consent response from each of the plurality of devices;
control the data distribution to the vehicle according to a determination result of the consent response; and
determine whether the consent request to the plurality of devices is needed before the consent request is made to the plurality of devices, wherein
the computer program code further causes the at least one processor to:
determine whether to make the consent request to the plurality of devices according to a determination result of the consent request, and
make the consent request to a first device and a second device among the plurality of devices in steps by making a first-step consent request to the first device and then making a second-step consent request to the second device.

4. The center device according to claim 3 , wherein
the computer program code further causes the at least one processor to:

make an identity verification request, as the second-step consent request, to the second device.

5. The center device according to claim 4 , wherein
the computer program code further causes the at least one processor to:
judge an identity verification response from the second device, and
perform the data distribution to the vehicle upon determining that the identity verification response from the second device is true.

6. The center device according to claim 5 , wherein
the computer program code further causes the at least one processor to:
make a registration request for user information to the second device upon determining that the identity verification response from the second device is false.

7. The center device according to claim 1 , wherein
the computer program code further causes the at least one processor to:
determine whether there is a change in a vehicle state; and
determine whether the consent request to the plurality of devices is needed based on a determination result of the change in the vehicle state.

8. A center device, comprising:
at least one processor; and
at least one memory storing computer program code, wherein
the computer program code, when executed by the at least one processor, causes the at least one processor to:
make a consent request to a plurality of devices for data distribution to a vehicle;
judge a consent response from each of the plurality of devices;
control the data distribution to the vehicle according to a determination result of the consent response; and
determine whether the consent request to the plurality of devices is needed before the consent request is made to the plurality of devices, wherein

the computer program code further causes the at least one processor to:
determine whether to make the consent request to the plurality of devices according to a determination result of the consent request;
determine whether there is a change in a vehicle state;
determine whether the consent request to the plurality of devices is needed based on a determination result of the change in the vehicle state; and
determine whether there is a change, as the change in the vehicle state, in at least one of a parking position, a traveling route, and a driving operation.

9. The center device according to claim 1 , wherein
the computer program code further causes the at least one processor to:
monitor an elapsed time from when the data distribution was performed last time to when a distribution event for the data distribution this time was established; and
determine whether the consent request to the plurality of devices is needed based on the elapsed time.

10. The center device according to claim 1 , wherein
the computer program code further causes the at least one processor to:
determine whether a charge for the data distribution will be incurred; and
determine whether the consent request to the plurality of devices is needed based on a determination result of whether the charge will be incurred.

11. The center device according to claim 1 , wherein
the computer program code further causes the at least one processor to:
make the consent request to the plurality of devices that include a mobile terminal carried by a user and a vehicle HMI device mounted in the vehicle.

12. A data distribution system, comprising:
a center device having at least one processor and memory configured to:
make a consent request to a plurality of devices for data distribution to a vehicle;
judge a consent response from each of the plurality of devices;
control the data distribution to the vehicle according to a determination result of the consent request; and
determine whether the consent request to the plurality of devices is needed before the consent request is made to the plurality of devices;

wherein the plurality of devices are each configured to make the consent response in response to the consent request from the center device;
wherein the at least one processor and memory of the center device are further configured to determine whether to make the consent request to the plurality of devices according to a determination result of whether the consent request to the plurality of devices is needed; and
wherein the at least one processor and memory of the center device are further configured to:
make the consent request to at least a first device and a second device among the plurality of devices upon determining that the consent request to the plurality of devices is needed; and
perform the data distribution to the vehicle upon determining that at least the consent response from the first device and the consent response from the second device indicate a permission.

13. A non-transitory, computer readable storage medium
