Abstract

A center includes a vehicle related device, which is communicably connected with multiple in-vehicle devices, and a service related device communicably connected with a service providing unit. The vehicle related device generates, for each vehicle, a shadow using multiple pieces of vehicle data repeatedly acquired from the in-vehicle device of corresponding vehicle, and stores the generated shadow in a shadow storage unit. The service related device generates indices corresponding to respective shadows, each of which is assigned with the timing identification information, and stores the generated indices in an index storage unit provided in the service related device. The service related device acquires, from the index storage unit, one of the indices corresponding to a designated parameter, and the vehicle related device acquires one of the multiple pieces of vehicle data from the shadow storage unit using the one of the indices, which is acquired corresponding to the designated parameter.

First claim

What is claimed is:

1 . A center comprising:
a vehicle related device communicably connected with multiple in-vehicle devices individually mounted on multiple vehicles, the vehicle related device performing data communication with the multiple in-vehicle devices; and a service related device communicably connected with a service providing unit and performing data communication with the service providing unit, wherein the vehicle related device includes a shadow generation unit generating, for each of the multiple vehicles, a shadow using multiple pieces of vehicle data repeatedly acquired from the in-vehicle device of corresponding vehicle, each of the multiple pieces of vehicle data generated as the shadow is assigned with vehicle identification information for identifying the corresponding vehicle and timing identification information for identifying a timing at which each of the multiple pieces of vehicle data is acquired, the shadow generation unit stores the shadow that includes the multiple pieces of vehicle data in a shadow storage unit provided in the vehicle related device, the service related device includes:
an index generation unit generating indices corresponding to respective shadows, each of which is assigned with the timing identification information, and stores the generated indices in an index storage unit provided in the service related device; and
an index acquisition unit that acquires, from the index storage unit, one of the indices corresponding to a designated parameter, and
the vehicle related device further includes a data acquisition unit acquiring one of the multiple pieces of vehicle data from the shadow storage unit using the one of the indices, which is acquired corresponding to the designated parameter.

2 . The center according to claim 1 , wherein
the vehicle related device includes a latest index generation unit that generate latest indices for identifying latest shadows of respective vehicles and store the latest indices in a latest index storage unit provided in the vehicle related device, and the index generation unit repeatedly acquires the latest indices from the latest index storage unit, and generates, as the indices corresponding to respective shadows, the latest indices, each of which is assigned with time information for specifying the shadow corresponding to the latest index.

3 . The center according to claim 2 , wherein
each of the latest indices includes vehicle position information indicating a position where the corresponding vehicle is present, and the index generation unit repeatedly acquires the latest indices for generating the indices corresponding to respective shadows.

4 . The center according to claim 1 , wherein
each of the indices includes specific information for specifying one of the multiple vehicles, which is necessary for the service providing unit to provide a service.

5 . The center according to claim 1 , wherein
the index acquisition unit:
acquires, from the service providing unit, a request that instructs acquisition of designated data of a designated vehicle at a designated time;
acquires, from the index storage unit, one of the indices corresponding to the designated time and the designated vehicle in the request; and
specifies one of the shadows based on the acquired index, and
the data acquisition unit of the vehicle related device acquires, from the shadow storage unit, the designated data included in the one of the shadows specified by the index acquisition unit.

6 . The center according to claim 1 , wherein
each of the shadows includes information related to a device mounted on the corresponding vehicle.

7 . The center according to claim 1 , wherein
the service related device includes an application programming interface through which the service providing unit accesses the service related device.

8 . The center according to claim 1 , wherein
the vehicle related device includes a vehicle control unit that controls each of the multiple vehicles on which the multiple in-vehicle device are respectively mounted, and the vehicle control unit acquires, from the service providing unit, a control instruction to one of the multiple vehicles without going through the service related device.

9 . A management method performed by a center, the center including a vehicle related device communicably connected with multiple in-vehicle devices, which are individually mounted on multiple vehicles, for performing data communication and a service related device communicably connected with a service providing unit for performing data communication, the management method comprising:
causing the vehicle related device to repeatedly acquire multiple pieces of vehicle data from each of the multiple in-vehicle devices and generate, for each of the multiple vehicles, a shadow using the acquired multiple pieces of vehicle data, wherein each of the multiple pieces of vehicle data generated as the shadow is assigned with vehicle identification information for identifying the corresponding vehicle and timing identification information for identifying a timing at which each of the multiple pieces of vehicle data is acquired; causing the vehicle related device to store the multiple pieces of vehicle data in a shadow storage unit provided in the vehicle related device; causing the service related device to generate indices corresponding to respective shadows, each of which is assigned with the timing identification information, and store the generated indices in an index storage unit provided in the service related device; causing the service related device to acquire, from the index storage unit, one of the indices corresponding to a designated parameter; and causing the vehicle related device to acquire one of the multiple pieces of vehicle data from the shadow storage unit using the one of the indices, which is acquired corresponding to the designated parameter.

10 . A computer-readable non-transitory storage medium storing a management program for causing a computer included in a center to execute instructions of the management program, the center including a vehicle related device communicably connected with multiple in-vehicle devices, which are individually mounted on multiple vehicles, for performing data communication and a service related device communicably connected with a service providing unit for performing data communication, the instructions comprising:
causing the vehicle related device to repeatedly acquire multiple pieces of vehicle data from each of the multiple in-vehicle devices and generate, for each of the multiple vehicles, a shadow using the acquired multiple pieces of vehicle data, wherein each of the multiple pieces of vehicle data generated as the shadow is assigned with vehicle identification information for identifying the corresponding vehicle and timing identification information for identifying a timing at which each of the multiple pieces of vehicle data is acquired; causing the vehicle related device to store the multiple pieces of vehicle data in a shadow storage unit provided in the vehicle related device; causing the service related device to generate indices corresponding to respective shadows, each of which is assigned with the timing identification information, and store the generated indices in an index storage unit provided in the service related device; causing the service related device to acquire, from the index storage unit, one of the indices corresponding to a designated parameter; and causing the vehicle related device to acquire one of the multiple pieces of vehicle data from the shadow storage unit using the one of the indices, which is acquired corresponding to
