Method and device for sharing functions of smart key

1. A device for providing information about a smart key, the device comprising:

a communicator configured to receive information about at least one function, performable by the smart key external to and independently from the device, for controlling a vehicle;

a controller configured to set a usage restriction for the at least one function; and

a user input unit configured to receive, from a user, a user input,

wherein the communicator is configured to provide, to an external device, information about the at least one function, the information including the set usage restriction,

wherein the information includes both of the set usage restriction and information for performing the at least one function capable of controlling at least one operation of the vehicle, and

wherein the controller is configured to set the usage restriction for the at least one function according to the user input received via the user input unit, and to add the set usage restriction to the received information about the at least one function.

2. The device of claim 1 , wherein the communicator is configured to receive, from the external device, a usage history of the at least one function, when the external device attempts to use the at least one function based on the provided information about the at least one function.

3. The device of claim 2 , further comprising an output unit configured to output the received usage history on a screen of the device.

4. The device of claim 1 , wherein:

the communicator is configured to receive, from the external device, a request to change the set usage restriction; and

the controller is configured to determine, according to a user input received via a user input unit, whether to accept the received request to change the set usage restriction.

5. The device of claim 4 , further comprising a storage configured to store the changed usage restriction when the controller accepts the received request to change the set usage restriction.

6. The device of claim 1 , wherein the usage restriction comprises at least one of:

a first condition that specifies a time period during which the external device is allowed to use the at least one function;

a second condition that specifies a distance between the smart key and the external device within which the external device is allowed to use the at least one function;

a third condition that specifies one or more users who are allowed to use the at least one function;

a fourth condition that specifies a type of the at least one function that the external device is allowed to use; and

a fifth condition that specifies a number of times that the external device is allowed to use the at least one function.

7. The device of claim 6 , wherein the first condition comprises the time period as starting from a time point when the information about the at least one function is provided to the external device, or a preset time interval.

8. The device of claim 6 , wherein the second condition comprises, as the specified distance, an area within a preset radius of a location of the device or an area within a preset radius of a location of the external device when the information about the at least one function is provided to the external device.

9. A method of providing information about a smart key, the method comprising:

receiving, by a device, information about at least one function, performable by the smart key external to and independently from the device, for controlling a vehicle;

setting a usage restriction for the at least one function; and

providing, to an external device, information about the at least one function, the information including the set usage restriction,

wherein the information includes both of the set usage restriction and information for performing the at least one function capable of controlling at least one operation of the vehicle, and

wherein the setting the usage restriction comprises setting the usage restriction for the at least one function according to a received user input received by the device.

10. The method of claim 9 , further comprising receiving, from the external device, a usage history of the at least one function, when the external device attempts to use the at least one function based on the provided information about the at least one function.

11. The method of claim 10 , further comprising outputting the received usage history on a screen of the device.

12. The method of claim 10 , further comprising:

receiving, from the external device, a request to change the set usage restriction; and

determining according to a received user input, whether to accept the received request to change the set usage restriction.

13. The method of claim 9 , wherein the usage restriction comprises at least one of:

a first condition that specifies a time period during which the external device is allowed to use the at least one function;

a second condition that specifies a distance within which the external device is allowed to use the at least one function;

a third condition that specifies one or more users who are allowed to use the at least one function;

a fourth condition that specifies a type of the at least one function that the external device is allowed to use; and

a fifth condition that specifies a number of times that the external device is allowed to use the at least one function.

14. The method of claim 13 , wherein the first condition comprises the time period as starting from a time point when the information about the at least one function is provided to the external device, or a preset time interval.

15. The method of claim 13 , wherein the second condition comprises, as the specified distance, an area within a preset radius of a location of the device or an area within a preset radius of a location of the external device when the information about the at least one function is provided to the external device.

16. A non-transitory computer-readable recording medium having recorded thereon a computer program, which, when executed by a computer, performs the method of claim 9 .

17. A device for controlling a vehicle by using information about a smart key, the device comprising:

a communicator configured to receive information about at least one function, performed by the smart key, for controlling a vehicle; and

a controller configured to identify a usage restriction included in the received information about the at least one function and to control an operation of the vehicle according to the identified usage restriction,

wherein the received information includes both of the set usage restriction and information used to perform the at least one function capable of controlling at least one operation of the vehicle, and

wherein the usage restriction comprises at least one of:

a first condition that specifies a distance within which the device is allowed to use the at least one function; and

a second condition that specifies a type of the at least one function that the external device is allowed to use.

18. A method of controlling a vehicle by using information about a smart key, the method comprising:

receiving information about at least one function, performed by the smart key, for controlling a vehicle;

identifying a usage restriction included in the received information about the at least one function; and

controlling an operation of the vehicle according to the identified usage restriction,

wherein the received information includes both of the set usage restriction and information used to perform the at least one function capable of controlling at least one operation of the vehicle, and

wherein the usage restriction comprises at least one of:

a first condition that specifies a distance within which the device is allowed to use the at least one function; and

a second condition that specifies a type of the at least one function that the external device is allowed to use.
