Abstract

A locking and unlocking system includes a controller. The controller is configured to acquire a state of locking and unlocking of a vehicle that is locked and unlocked based on locking and unlocking instruction information acquired from a portable terminal, and send a notification to a first device associated with the vehicle, when the vehicle is not locked during a period of time from when the vehicle is unlocked based on the locking and unlocking instruction information acquired from the portable terminal until a first timing.

First claim

What is claimed is:

1. A locking and unlocking system comprising:
a controller configured to:
acquire a state of locking and unlocking of a vehicle that is locked and unlocked based on instruction information acquired within a valid period of authentication from a portable terminal; and
transmit a notification to a delivery management server when the vehicle is not locked during a period of time from when the vehicle is unlocked based on the instruction information until a first timing that arrives after the valid period of the authentication expires,
the controller is configured to transmit a notification to the delivery management server, when the vehicle is locked during the period of time from when the vehicle is unlocked based on the instruction information acquired from the portable terminal until a second timing, and
wherein the controller is configured to transmit a locking command to the vehicle to lock the vehicle when the vehicle is not locked for the period of time until the first timing.

2. The locking and unlocking system according to claim 1 , wherein the controller is configured to transmit a notification to the delivery management server in a case where the time of expiration of the authentication has passed and the vehicle is not locked.

3. The locking and unlocking system according to claim 1 , wherein the second timing is a timing that arrives before the valid period of the authentication expires.

4. The locking and unlocking system according to claim 1 , wherein the controller is provided in the delivery management server.

5. The locking and unlocking system according to claim 4 , wherein the valid period of the authentication is specified by the delivery management server.

6. The locking and unlocking system according to claim 1 , wherein the delivery management server manages a plurality of portable terminals.

7. A method of locking and unlocking a vehicle, comprising:
acquiring a state of locking and unlocking of a vehicle that is locked and unlocked based on instruction information acquired within a valid period of authentication from a portable terminal;
transmitting a notification to a delivery management server when the vehicle is not locked during a period of time from when the vehicle is unlocked based on the instruction information until a first timing that arrives after the valid period of the authentication expires;
transmitting a notification to the delivery management server, when the vehicle is locked during the period of time from when the vehicle is unlocked based on the instruction information acquired from the portable terminal until a second timing; and
transmitting a locking command to the vehicle to lock the vehicle when the vehicle is not locked for the period of time until the first timing.

8. The method of locking and unlocking a vehicle according to claim 7 , wherein the second timing is a timing that arrives before the valid period of the authentication expires.

9. The method of locking and unlocking a vehicle according to claim 8 , wherein the valid period of the authentication is specified by the delivery management server.
