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.

Abstract: A center includes: a vehicle related device data-communicably connected with multiple in-vehicle devices; and a service related device capable of performing data communication with a service providing unit. The vehicle related device: repeatedly acquires, from each in-vehicle device, a vehicle data group configured in a first data structure in which multiple pieces of vehicle data are classified into categories; generates, for each vehicle, a shadow by assigning vehicle identification information and timing identification information to the vehicle data group; and stores the generated shadow in a form of the first data structure. In response to receiving, from the service providing unit, a request to instruct acquisition of a designated data, which corresponds to a predetermined vehicle or a predetermined category, the service related device instructs the vehicle related device to acquire the designated data of the predetermined vehicle at a predetermined time.

Abstract: A system includes multiple in-vehicle devices individually mounted on multiple vehicles and a center capable of performing data communication with the multiple in-vehicle devices. Each in-vehicle device transmits vehicle data related to another vehicle device to the center in a first cycle. The center is configured to: store, in a second storage unit, the vehicle data sequentially transmitted from each in-vehicle device; store, in a third storage unit, an index that includes information associated with the vehicle data stored in the second storage unit; perform a first update by adding the received vehicle data to the vehicle data stored in the second storage unit; and perform a second update by adding the index stored in the third storage unit in association with latest one of the vehicle data stored in the second storage unit in a second cycle.

Abstract: When an interface unit has received a first access request, first control units acquire vehicle data from storage units, and provide the vehicle data to a request source through an interface unit. When the interface unit has received a second access request, a second control unit acquires the access result including the vehicle data from a vehicle-mounted machine by accessing the vehicle-mounted machine, and provides the access result to the request source through the interface unit.
