In-vehicle device, data generation method, storage medium storing data generation program, vehicle system and in-vehicle system

A data generation method implemented by an in-vehicle device that is mounted in a vehicle and includes a unit that is configured to communicate data with a center configured to manage vehicle data, the method comprising:

• normalizing a plurality of pieces of the vehicle data acquired from an electronic control unit mounted in the vehicle;
• structuring the plurality of pieces of the vehicle data that are normalized into a predetermined data structure;
• and
• transmitting, with the unit, the plurality of pieces of the vehicle data that are structured to the center through a communicator.

A non-transitory, tangible storage medium for storing a data generation program for an in-vehicle device that is mounted in a vehicle and includes a unit that is configured to communicate data with a center configured to manage vehicle data, the data generation program, when executed by a computer of the in-vehicle device, causing the computer to:

• normalize a plurality of pieces of the vehicle data acquired from an electronic control unit mounted in the vehicle;
• structure the plurality of pieces of the vehicle data that are normalized into a predetermined data structure;
• and
• cause the unit to transmit the plurality of pieces of the vehicle data that are structured to the center through a communicator.

A vehicle system, comprising:

• a center that is configured to manage vehicle data transmitted from a plurality of vehicles;
• and
• a plurality of in-vehicle devices that are configured to wirelessly communicate with the center through a communicator, wherein
• each of the plurality of in-vehicle devices 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 the center,
• 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 the communicator, and
• the center includes:
• a data receiving portion that is configured to receive the plurality of pieces of the structured vehicle data transmitted from the plurality of in-vehicle devices;
• and
• a vehicle data storage portion that is configured to store, for each of the plurality of vehicles, the plurality of pieces of the vehicle data that are structured by the data structuring portion and received by the data receiving portion.

An in-vehicle system, comprising:

• an electronic control unit that is mounted in a vehicle and is configured to transmit vehicle data;
• an in-vehicle device that is configured to acquire the vehicle data transmitted from the electronic control unit, wherein
• the in-vehicle device includes:
• 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 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 the 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 structured by the data structuring portion to the center through a communicator.
