Abstract

A vehicle includes: a communication unit performing low frequency (LF) communication and radio frequency (RF) communication with a fob key and performing short-range communication with a portable device; and a controller estimating a position of a user having the fob key using the LF and RF communication with the fob key and controlling a connection between the portable device and the communication unit according to the estimated position of the user using the short-range communication with the portable device.

Claims

1. A vehicle comprising:

a communication unit performing a low frequency (LF) communication and a radio frequency (RF) communication with a fob key and performing a short-range communication with a portable device; and

a controller estimating a position of a user having the fob key using the LF and RF communication with the fob key and controlling a connection between the portable device and the communication unit according to the estimated position of the user using the short-range communication with the portable device, wherein

the controller establishes a retrieving start point of the vehicle and a retrieving completion point of the vehicle and determines an overlapping area of a vehicle controllable area at the retrieving start point of the vehicle and a vehicle controllable area at the retrieving completion point of the vehicle as a recommended control position,

the communication unit receives a retrieving command from the portable device, and

in response to receiving the retrieving command, the controller determines whether the recommended control position is identical to the estimated position of the user and moves the vehicle to the retrieving completion point when it is determined that the recommended control position is identical to the estimated position of the user.

2. The vehicle of claim 1, wherein the communication unit receives strength information of a LF signal from the fob key, and the controller estimates the position of the user based on the received strength information of the LF signal.

3. The vehicle of claim 2, wherein the controller estimates a distance between the user and the vehicle based on the strength information of the LF signal and permits the connection between the portable device and the communication unit when the estimated distance between the user and the vehicle is less than a predetermined reference distance.

4. The vehicle of claim 1, wherein the controller establishes a plurality of vehicle controllable areas having a predetermined range from the vehicle and controls the connection between the portable device and the communication unit using the short-range communication according to a vehicle controllable area among the plurality of vehicle controllable areas in which the user is located.

5. The vehicle of claim 4, wherein:

the plurality of vehicle controllable areas includes a first area and a second area, and

the controller blocks the connection between the portable device and the communication unit when the user is located in the first area and permits the connection between the portable device and the vehicle when the user is located in the second area.

6. The vehicle of claim 1, further comprising:

a storage unit storing a first authentication code,

wherein the communication unit receives a second authentication code from the portable device, and the controller permits the connection between the portable device and the communication unit when the distance between the user and the vehicle is less than a predetermined reference distance and the first authentication code stored in the storage unit is identical to the second authentication code received from the portable device.

7. The vehicle of claim 1, wherein the communication unit transmits position information of the user to the portable device.

8. The vehicle of claim 1, wherein the controller stops retrieving control of the vehicle when it is determined that the recommended control position is not identical to the estimated position of the user.

9. The vehicle of claim 1, wherein the communication unit transmits information related to the recommended control position to the portable device.

10. A controlling method of a vehicle, the method comprising:

performing a low frequency (LF) communication and a radio frequency (RF) communication with a fob key;

performing a short-range communication with a portable device;

estimating a position of a user having the fob key using the LF and RF communication with the fob key;

controlling a connection between the portable device and a communication unit of the vehicle according to the estimated position of the user using the short-range communication with the portable device;

establishing a retrieving start point of the vehicle and a retrieving completion point of the vehicle;

determining an overlapping area of a vehicle controllable area at the retrieving start point and a vehicle controllable area at the retrieving completion point as a recommended control position;

receiving a retrieving command from the portable device;

in response to receiving the retrieving command, determining whether the recommended control position is identical to the estimated position of the user; and

moving the vehicle to the retrieving completion point when it is determined that the recommended control position is identical to the estimated position of the user.

11. The controlling method of claim 10, wherein:

the performing of the LF and RF communication with the fob key comprises receiving strength information of a LF signal from the fob key; and

the estimating of the position of the user comprises estimating a position of the user based on the received strength information of the LF signal.

12. The controlling method of claim 11, wherein:

the estimating of the position of the user comprises estimating a distance between the user and the vehicle based on the strength information of the LF signal; and

the controlling of the connection between the portable device and the communication unit comprises permitting a connection between the portable device and the communication unit when the distance between the user and the vehicle is less than a predetermined reference distance.

13. The controlling method of claim 10, wherein the controlling of the connection between the portable device and the communication unit comprises:

establishing a plurality of vehicle controllable areas having a predetermined range from the vehicle and controlling the connection between the portable device and the communication unit using the short-range communication according to a vehicle controllable area among the plurality of vehicle controllable areas in which the user is located.

14. The controlling method of claim 10 wherein, the controlling of the connection between the portable device and the communication unit comprises:

receiving a second authentication code from the portable device; and

permitting the connection between the portable device and the communication unit when the distance between the user and the vehicle is less than the predetermined reference distance and a first authentication code stored in a storage unit is identical to the second authentication code received from the portable device.

15. The controlling method of claim 10, further comprising:

transmitting position information of the user to the portable device.

16. The controlling method of claim 10, further comprising:

stopping retrieving control of the vehicle when it is determined that the recommended control position is not identical to the estimated position of the user.
