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: An in-vehicle device mounted in a vehicle includes: at least one processor; and at least one memory storing computer program code. The computer program code, when executed by the at least one processor, causes the at least one processor to serve as a unit that is configured to communicate data with a center configured to manage vehicle data. The unit includes: a normalization portion that is configured to normalize a plurality of pieces of the vehicle data acquired from an electronic control unit mounted in the vehicle; a data structuring portion that is configured to structure the plurality of pieces of the vehicle data that are normalized by the normalization portion into a predetermined data structure; and a data transmission portion that is configured to transmit the plurality of pieces of the vehicle data that are structured by the data structuring portion to the center through a communicator.

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 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: An in-vehicle device includes a first controller and a second controller. The first controller includes at least one physical core for executing a first unit related to control of hardware and a second unit related to provision of a service. The second controller starts the first controller in response to occurrence of a start trigger. The first controller starts the first unit, and then starts the second unit when the first controller is started by the second controller. The first unit and the second unit are restarted when an abnormality of the first unit is detected by the second controller or an abnormality of the second unit is detected by the first unit. The first unit, the second unit and the second controller are restarted when an abnormality of the second controller is detected by the second controller.
