Information processing device

An information processing device that manages a storage device mounted on a vehicle and rewritable on a cell-by-cell basis, the information processing device comprising:

• a processor configured to
• collect pieces of data from each of a plurality of applications that are executed in the vehicle at a collection timing;
• integrate the pieces of the data collected from the plurality of applications at the collection timing into a single piece of integrated data;
• execute a first command, the first command being a command requesting writing of the integrated data to the storage device;
• and
• execute a second command, the second command being a command to immediately execute the writing of the integrated data to the storage device based on the first command, wherein
• a constant power supply mode and an auxiliary power supply mode are prepared as a supply mode for supplying power,
• the number of in-vehicle devices to which power is supplied from a power supply is larger when the auxiliary power supply mode is selected as the supply mode than when the constant power supply mode is selected as the supply mode,
• the supply mode is switched from the constant power supply mode to the auxiliary power supply mode when a user approaches the vehicle, and the supply mode is switched from the auxiliary power supply mode to the constant power supply mode when the user moves away from the vehicle, and
• the collection timing includes a timing at which the supply mode is switched from the auxiliary power supply mode to the constant power supply mode.
