Abstract

An information processing device comprising a processor, the processor being configured to: in a case in which a door of a vehicle is locked, determine whether or not a terminal that operates as an electronic key is located in the vehicle; and in a case in which the terminal is determined to be located in the vehicle, perform control to restrict at least a subset of functions, among functions of the vehicle that are controlled in accordance with communications with the terminal, based on a lock trigger causing the locking of the door of the vehicle.

Claims (33)

1 . An information processing device mounted to a vehicle, the information processing device comprising at least one processor and memory that stores a restriction settings information relating to a specification of restrictions of functions, the restriction settings information being determined for each command for locking the vehicle, the at least one processor configured to:

control a plurality of functions of the vehicle based on an electronic key function, in accordance with a communication between a smartphone providing the electronic key function and the vehicle; and

specify a restriction of a control using the electronic key function, among the plurality of functions of the vehicle, based on the restriction settings information,

wherein the restriction settings information includes a specification that corresponds to a locking operation performed when a user boards the vehicle, or a locking operation performed when the user disembarks from the vehicle, and

wherein contents of the restrictions in the restriction settings information are specified for each of lock triggers causing locking of a door of the vehicle and each of the plurality of functions of the vehicle.

2 . The information processing device according to claim 1 , wherein the at least one processor is configured to cause the smartphone to display the restriction settings information related to a subset of the functions restricted in accordance with one of the lock triggers.

3 . The information processing device according to claim 1 , wherein the at least one processor is configured to:

determine whether or not the smartphone is located in a cabin of the vehicle; and

in a case in which the smartphone is determined to be located in the cabin of the vehicle, cause the smartphone to display the restriction settings information.

4 . The information processing device according to claim 1 , wherein the at least one processor is configured to control the plurality of functions of the vehicle based on an electronic key function, in accordance with a communication by Bluetooth between the smartphone and the vehicle.

5 . The information processing device according to claim 3 , wherein the at least one processor is configured to use a communication result between the smartphone and a communication device on board the vehicle to determine whether or not the smartphone is located in a cabin of the vehicle.

6 . An information processing method comprising:

storing a restriction settings information relating to a specification of restrictions of functions, the restriction settings information being determined for each command for locking a vehicle;

controlling a plurality of functions of the vehicle based on an electronic key function, in accordance with a communication between a smartphone providing the electronic key function and the vehicle; and

specifying a restriction of a control using the electronic key function, among the plurality of functions of the vehicle, based on the restriction settings information,

wherein the restriction settings information includes a specification that corresponds to a locking operation performed when a user boards the vehicle, or a locking operation performed when the user disembarks from the vehicle, and

wherein contents of the restrictions in the restriction settings information are specified for each of lock triggers causing locking of a door of the vehicle and each of the plurality of functions of the vehicle.

7 . The information processing method according to claim 6 , further comprising:

determining whether or not the smartphone is located in a cabin of the vehicle; and

in a case in which the smartphone is determined to be located in the cabin of the vehicle, causing the smartphone to display the restriction settings information.

8 . The information processing method according to claim 6 , wherein the plurality of functions of the vehicle are controlled based on an electronic key function, in accordance with a communication by Bluetooth between the smartphone and the vehicle.

9 . The information processing method according to claim 7 , wherein a communication result between the smartphone and a communication device on board the vehicle is used to determine whether or not the smartphone is located in a cabin of the vehicle.

10 . A non-transitory computer readable recording medium storing an information processing program executable by a computer to perform processing comprising:

storing a restriction settings information relating to a specification of restrictions of functions, the restriction settings information being determined for each command for locking a vehicle;

controlling a plurality of functions of the vehicle based on an electronic key function, in accordance with a communication between a smartphone providing the electronic key function and the vehicle; and

specifying a restriction of a control using the electronic key function, among the plurality of functions of the vehicle, based on the restriction settings information,

wherein the restriction settings information includes a specification that corresponds to a locking operation performed when a user boards the vehicle, or a locking operation performed when the user disembarks from the vehicle, and

wherein contents of the restrictions in the restriction settings information are specified for each of lock triggers causing locking of a door of the vehicle and each of the plurality of functions of the vehicle.

11 . The non-transitory computer readable recording medium according to claim 10 , further comprising:

determining whether or not the smartphone is located in a cabin of the vehicle; and

in a case in which the smartphone is determined to be located in the cabin of the vehicle, causing the smartphone to display the restriction settings information.

12 . The non-transitory computer readable recording medium according to claim 10 , wherein the plurality of functions of the vehicle are controlled based on an electronic key function, in accordance with a communication by Bluetooth between the smartphone and the vehicle.

13 . The non-transitory computer readable recording medium according to claim 11 , wherein a communication result between the smartphone and a communication device on board the vehicle is used to determine whether or not the smartphone is located in a cabin of the vehicle.
