Onboard device, data provision system, data provision method, and storage medium storing program

A data provision system comprising:

• one or more onboard devices;
• and
• a server provided outside a vehicle equipped with the onboard device,
• wherein:
• the onboard device includes
• a data acquisition unit configured to execute a transmission process to transmit a command to a vehicle network of a vehicle equipped with the onboard device according to an instruction manual indicating one or more types of standard vehicle data, which are standardized vehicle data, and obtain specific vehicle data, which is vehicle data indicated in a format unique to a vehicle, from the vehicle network,
• a standard vehicle data storage unit configured to convert the specific vehicle data obtained by the data acquisition unit into a format of the standard vehicle data and store the standard vehicle data,
• an application execution unit configured to execute one or more application programs that utilize the standard vehicle data, and
• an application programming interface (API) group, which is a collection of application programming interfaces prepared for each of the standard vehicle data, configured to provide a function to obtain the standard vehicle data from the standard vehicle data storage unit for the one or more application programs executed by the application execution unit;
• and
• the server includes a digital twin database that stores at least one of the standard vehicle data transmitted from each of the onboard devices and the digital twin data emulating the vehicle equipped with the onboard device generated based on the standard vehicle data.

A method for providing an application execution environment to provide one or more application programs arranged in an onboard device with vehicle data obtained via a vehicle network of a vehicle equipped with the onboard device, the method comprising:

• executing a transmission process to obtain specific vehicle data, which is vehicle data indicated in a format unique to the vehicle, from the vehicle network by transmitting a command to the vehicle network according to an instruction manual indicating one or more types of standard vehicle data, which are standardized vehicle data;
• converting the specific vehicle data obtained by executing the transmission process into a format of the standard vehicle data and storing the standard vehicle data in a standard vehicle data storage unit;
• and
• providing the standard vehicle data to the application program by an API group, which is a collection of application programming interfaces prepared for each of the standard vehicle data, to provide a function to obtain the standard vehicle data from the standard vehicle data storage unit.

A non-transitory computer readable storage medium storing a program for providing vehicle data obtained via a vehicle network of a vehicle equipped with an onboard device to one or more application programs arranged in the onboard device, the program comprising instructions configured to, when executed by a processor, cause the processor to:

• execute a transmission process to obtain specific vehicle data, which is vehicle data indicated in a format unique to the vehicle, from the vehicle network by transmitting a command to the vehicle network according to an instruction manual indicating one or more types of standard vehicle data, which are standardized vehicle data;
• convert the specific vehicle data obtained by executing the transmission process into the format of the standard vehicle data and store the standard vehicle data in a standard vehicle data storage unit;
• and
• provide the standard vehicle data to the application program by an API group, which is a collection of application programming interfaces prepared for each of the standard vehicle data, to provide a function to obtain the standard vehicle data from the standard vehicle data storage unit.
