Information processing device, information processing method, and storage medium storing information processing program

An information processing method for controlling writing of data to a storage mounted on a vehicle by multiple applications, wherein

• a storage area of the storage includes a shared area shared by multiple applications,
• a priority for allowing writing of data to the shared area is set for each of the applications,
• data of each of the applications includes transfer data to be transmitted to a data center and normal data different from the transfer data, and
• the information processing method comprises:
• setting a priority of writing of the transfer data to the shared area to be higher than a priority of writing of the normal data to the shared area so that the transfer data is stored in the shared area in preference to the normal data;
• assigning priorities for writing the normal data by adding a first prescribed value to priorities assigned for writing the transfer data, the first prescribed value being greater than a difference between a highest value and a lowest value of the priorities for writing the transfer data, so that the priorities for writing the normal data are outside a range from the highest value to the lowest value of the priorities for writing the transfer data;
• determining, in response to receiving a transfer data write request, whether an amount of available storage in the shared area is less than or equal to a second prescribed value;
• deleting data of the application having a lowest priority from the shared area in response to determining that the amount of available storage of the shared area is less than or equal to the second prescribed value;
• writing the transfer data to the shared area;
• and
• transmitting the written transfer data to the data center.

A non-transitory storage medium storing an information processing program, the program being configured to cause a computer to execute a process of controlling writing of data to a storage mounted on a vehicle by multiple applications, wherein

• a storage area of the storage includes a shared area shared by multiple applications,
• a priority for allowing writing of data to the shared area is set for each of the applications,
• data of each of the applications includes transfer data to be transmitted to a data center and normal data different from the transfer data, and
• the information processing program is configured to cause the computer to:
• set a priority of writing of the transfer data to the shared area to be higher than a priority of writing of the normal data to the shared area so that the transfer data is stored in the shared area in preference to the normal data;
• assign priorities for writing the normal data by adding a first prescribed value to priorities assigned for writing the transfer data, the first prescribed value being greater than a difference between a highest value and a lowest value of the priorities for writing the transfer data, so that the priorities for writing the normal data are outside a range from the highest value to the lowest value of the priorities for writing the transfer data;
• determine, in response to receiving a transfer data write request, whether an amount of available storage in the shared area is less than or equal to a second prescribed value;
• delete data of the application having a lowest priority from the shared area in response to determining that the amount of available storage of the shared area is less than or equal to the second prescribed value;
• write the transfer data to the shared area;
• and
• transmit the written transfer data to the data center.
