Abstract

An information processing device includes a processor configured to: acquire a usage history of a first device included in a vehicle as a first usage history; acquire a usage history of a second device included in the vehicle and different from the first device as a second usage history; estimate a first replacement time to replace a first consumable part included in the first device based on the first usage history; estimate a second replacement time to replace a second consumable part included in the second device based on the second usage history; and when a necessary condition that the second replacement time is later than the first replacement time is satisfied, change control for the first device so as to reduce wear of the first consumable part compared to when the second replacement time is the same as or earlier than the first replacement time.

Claims (31)

1 . An information processing device comprising a processor configured to:

acquire a usage history of a first device included in a vehicle as a first usage history,

acquire a usage history of a second device included in the vehicle as a second usage history, the second device being a device different from the first device,

estimate a first replacement time based on the first usage history, the first replacement time being a time to replace a first consumable part included in the first device,

estimate a second replacement time based on the second usage history, the second replacement time being a time to replace a second consumable part included in the second device, and

when a necessary condition that the second replacement time is later than the first replacement time is satisfied, change control of the first device such that wear of the first consumable part is reduced compared to when the second replacement time is the same as or earlier than the first replacement time, wherein

the first device is a mechanical brake device configured to generate a braking force on the vehicle;

the second device is an internal combustion engine configured to function as a driving source for the vehicle; and

the processor is configured to, when a necessary condition that the second replacement time is later than the first replacement time is satisfied, achieve the braking force required for the vehicle by reducing the braking force on the vehicle to be generated by the brake device and increasing the braking force on the vehicle to be generated by engine braking using the internal combustion engine compared to when the second replacement time is the same as or earlier than the first replacement time.

2 . The information processing device according to claim 1 , wherein:

the first device is a mechanical brake device configured to generate a braking force on the vehicle;

the second device is a motor generator configured to function as a driving source for the vehicle by operating as an electric motor and to generate the braking force on the vehicle by operating as an electric generator; and

the processor is configured to, when a necessary condition that the second replacement time is later than the first replacement time is satisfied, achieve the braking force required for the vehicle by reducing the braking force on the vehicle to be generated by the brake device and increasing the braking force on the vehicle to be generated by the motor generator compared to when the second replacement time is the same as or earlier than the first replacement time.

3 . A non-transitory storage medium storing instructions that are executable by one or more processors and that cause the one or more processors to perform functions comprising causing an information processing device to:

acquire a usage history of a first device included in a vehicle as a first usage history,

acquire a usage history of a second device included in the vehicle as a second usage history, the second device being a device different from the first device,

estimate a first replacement time based on the first usage history, the first replacement time being a time to replace a first consumable part included in the first device,

estimate a second replacement time based on the second usage history, the second replacement time being a time to replace a second consumable part included in the second device, and

when a necessary condition that the second replacement time is later than the first replacement time is satisfied, change control of the first device such that wear of the first consumable part is reduced compared to when the second replacement time is the same as or earlier than the first replacement time, wherein:

the first device is a mechanical brake device configured to generate a braking force on the vehicle;

the second device is an internal combustion engine configured to function as a driving source for the vehicle; and

when a necessary condition that the second replacement time is later than the first replacement time is satisfied, achieve the braking force required for the vehicle by reducing the braking force on the vehicle to be generated by the brake device and increasing the braking force on the vehicle to be generated by engine braking using the internal combustion engine compared to when the second replacement time is the same as or earlier than the first replacement time.

4 . An information processing method comprising causing an information processing device to:

acquire a usage history of a first device included in a vehicle as a first usage history,

acquire a usage history of a second device included in the vehicle as a second usage history, the second device being a device different from the first device,

estimate a first replacement time based on the first usage history, the first replacement time being a time to replace a first consumable part included in the first device,

estimate a second replacement time based on the second usage history, the second replacement time being a time to replace a second consumable part included in the second device, and

when a necessary condition that the second replacement time is later than the first replacement time is satisfied, change control of the first device such that wear of the first consumable part is reduced compared to when the second replacement time is the same as or earlier than the first replacement time, wherein:

the first device is a mechanical brake device configured to generate a braking force on the vehicle;

the second device is an internal combustion engine configured to function as a driving source for the vehicle; and

when a necessary condition that the second replacement time is later than the first replacement time is satisfied, achieve the braking force required for the vehicle by reducing the braking force on the vehicle to be generated by the brake device and increasing the braking force on the vehicle to be generated by engine braking using the internal combustion engine compared to when the second replacement time is the same as or earlier than the first replacement time.
