Package delivery method, package delivery system and delivery management device

1. A package delivery method, comprising:

receiving, by a first unmanned delivery vehicle, authentication information input by a user; and

unlocking, by a second unmanned delivery vehicle, a key of a storage of the second unmanned delivery vehicle, which stores a package addressed to the user, based on the authentication information received by the first unmanned delivery vehicle.

2. The package delivery method according to claim 1 , further comprising:

authenticating, by a server, when receiving the authentication information from the first unmanned delivery vehicle, the user based on the received authentication information; and

transmitting, by the server, to the second unmanned delivery vehicle, an instruction to unlock the key of the storage storing the package addressed to the user when the package addressed to the user is stored in the second unmanned delivery vehicle.

3. The package delivery method according to claim 1 , further comprising authenticating, when the second unmanned delivery vehicle has received the authentication information from the first unmanned delivery vehicle and the package addressed to the user is stored in the second unmanned delivery vehicle, the user who has input the received authentication information,

wherein the unlocking includes unlocking, by the second unmanned delivery vehicle, the key of the storage storing the package addressed to the user when the user is authenticated.

4. The package delivery method according to claim 1 , further comprising:

authenticating, by the first unmanned delivery vehicle, the user based on the authentication information; and

transmitting, by the first unmanned delivery vehicle, to the second unmanned delivery vehicle, an instruction to unlock the key of the storage storing the package addressed to the user when the package addressed to the user is stored in the second unmanned delivery vehicle.

5. The package delivery method according to claim 4 , further comprising:

transmitting, by a server, the authentication information to the user; and

transmitting, by the server, to the first unmanned delivery vehicle, determination information for determining whether the authentication information for authenticating the user is appropriate,

wherein authenticating the user includes authenticating, by the first unmanned delivery vehicle, the user based on the authentication information and the determination information.

6. The package delivery method according to claim 1 , further comprising:

authenticating, by a server, when receiving the authentication information from the first unmanned delivery vehicle, the user who has input the received authentication information; and

transmitting, by the first unmanned delivery vehicle, to the second unmanned delivery vehicle, an instruction to unlock the key of the storage storing the package addressed to the user when the user is authenticated and the package addressed to the user is stored in the second unmanned delivery vehicle.

7. The package delivery method according to claim 1 , further comprising transmitting, by the server, the authentication information to the user.

8. The package delivery method according to claim 1 ,

wherein the first unmanned delivery vehicle includes a storage,

wherein a periphery of each of the first and second unmanned delivery vehicles includes a first surface on which a door of the storage is arranged, a second surface, which faces a direction different from a direction of the first surface, and on which a device for inputting the authentication information is arranged, and a third surface opposed to the second surface, and

wherein the package delivery method further comprises moving at least one of the first unmanned delivery vehicle or the second unmanned delivery vehicle so that the second surface of one of the first unmanned delivery vehicle and the second unmanned delivery vehicle is adjacent to the third surface of another of the first unmanned delivery vehicle and the second unmanned delivery vehicle.

9. A package delivery system, comprising:

at least one processor; and

at least one memory device that stores a plurality of instructions which, when executed by the at least one processor, causes the at least one processor to:

receive authentication information input by a user; and

unlock a key of a storage of a second unmanned delivery vehicle, which stores a package addressed to the user, based on the authentication information received by a first unmanned delivery vehicle.

10. A delivery management device, comprising:

at least one processor; and

at least one memory device that stores a plurality of instructions which, when executed by the at least one processor, causes the at least one processor to:

acquire authentication information input by a user to a first unmanned delivery vehicle;

authenticate the user based on the authentication information; and

transmit, to a second unmanned delivery vehicle, an instruction to unlock a key of a storage storing a package addressed to the user when the package addressed to the user is stored in the second unmanned delivery vehicle.
