Abstract

A method for remotely controlling vehicle parking including recognizing a smart key in a first region by a vehicle, upon recognizing the smart key, activating a distance sensor of a camera and a parking assistance system (PAS) by the vehicle, recognizing a driver having the smart key through the activated camera, setting a position of the driver as a reference point by the vehicle, and calculating a detected distance of the driver and the vehicle through the PAS, and after the setting of the reference point and the calculating of the detected distance, moving forward or backward based on the detected distance or turning left or right based on a change in a position of the driver in right and left directions with respect to the reference point while receiving a parking signal from the smart key.

Claims

1. A method for remotely controlling vehicle parking, the method comprising:

recognizing a smart key in a first region by a vehicle;

upon recognizing the smart key, activating a distance sensor of a camera and a parking assistance system (PAS) by the vehicle;

recognizing a driver having the smart key through the activated camera, setting a position of the driver as a reference point by the vehicle, and calculating a detected distance of the driver and the vehicle through the PAS; and

after the setting of the reference point and the calculating of the detected distance, moving forward or backward based on the detected distance or turning left or right based on a change in a position of the driver in right and left directions with respect to the reference point while receiving a parking signal from the smart key.

2. The method according to claim 1, further comprising stopping the vehicle when the vehicle does not receive a parking signal from the smart key or when a detected distance of the driver or an obstacle is equal to or less than a threshold distance.

3. The method according to claim 2, wherein the step of recognizing of the smart key is performed after activating starting by the vehicle.

4. The method according to claim 3, wherein the step of activating of the starting further comprises activating the starting of the vehicle by receiving a first signal from the smart key positioned in a second region.

5. The method according to claim 3, wherein the step of recognizing of the smart key further comprises:

upon receiving a second signal from the vehicle by the smart key, transmitting a third signal comprising authentication information of the smart key; and

upon receiving the third signal by the vehicle, determining whether the smart key is an authenticated smart key.

6. The method according to claim 3, wherein the step of calculating of the detected distance of the driver and the vehicle through the PAS further comprises identifying the detected distance with at least two preset levels that are divided based on a threshold range set according to the calculated detected distance.

7. The method according to claim 3, wherein:

the PAS comprises at least one ultrasonic sensor; and

the step of calculating of the detected distance of the driver and the vehicle through the PAS further comprises transmitting and receiving an ultrasonic wave by the at least one ultrasonic sensor and calculating the detected distance.

8. The method according to claim 6, wherein the moving forward or backward or the turning left or right comprises:

moving forward when the detected distance is increased;

moving backward when the detected distance is reduced;

turning right when the driver is positioned right of the reference point; and

turning left when the driver is positioned left of the reference point.

9. The method of claim 8, wherein the moving forward when the detected distance is increased, the moving backward when the detected distance is reduced, the turning right when the driver is positioned right of the reference point, or the turning left when the driver is positioned left of the reference point further comprises controlling at least one of a drive system, a brake system, and a steering system of the vehicle.

10. The method of claim 9, wherein the moving forward when the detected distance is increased, the moving backward when the detected distance is reduced, the turning right when the driver is positioned right of the reference point, or the turning left when the driver is positioned left of the reference point further comprises changing a steering angle of the steering system in consideration of a distance degree by which the driver is positioned right or left of the reference point.

11. The method according to claim 5, wherein:

the first region is a region in which the vehicle is capable of recognizing the smart key by receiving a third signal from the smart key; and

the second region is a region in which the vehicle is capable of activating starting of the vehicle by receiving the first signal from the smart key.

13. The apparatus according to claim 11, wherein the controller controls at least one of a drive system, a brake system, and a steering system to stop the vehicle when the SMK does not receive the parking signal from the smart key or a detected distance of the driver or an obstacle is equal to or less than a threshold distance.

15. The apparatus according to claim 13, wherein the communication unit transmits information about whether the smart key is recognized upon receiving a third signal containing authentication information from the smart key.

17. The apparatus according to claim 13, wherein, when the communication unit receives the detected distance from the PAS comprising at least one ultrasonic sensor, the controller identifies the detected distance with at least two preset levels that are divided based on a threshold range set according to the calculated detected distance.

18. The apparatus according to claim 13, wherein the controller controls at least one of a drive system, a brake system, and a steering system to move forward when the detected distance is increased, to move backward when the detected distance is reduced, to turn right when the driver is positioned right of the reference point, or to turn left when the driver is positioned left of the reference point.

19. The apparatus according to claim 18, wherein the controller changes a steering angle of the steering system in consideration of a distance degree by which the driver is positioned right or left of the reference point.

20. The apparatus according to claim 13, wherein the SMK comprises a long frequency (LF) antenna.

21. The apparatus according to claim 13, wherein the communication unit is connected to the SMK and the camera via CAN communication and is connected to the PAS via LIN communication.

22. The apparatus according to claim 13, wherein:

the first region is a region in which the vehicle is capable of recognizing the smart key by receiving a third signal from the smart key; and

the second region is a region in which the vehicle is capable of activating starting of the vehicle by receiving the first signal from the smart key.

24. A computer readable recording medium having recorded thereon a program for executing the method according to claim 1.

12. An apparatus for remotely controlling vehicle parking, the apparatus comprising:

a controller for, upon recognizing the smart key in a first region, activating a distance sensor of a camera and a parking assistance system (PAS), recognizing a driver having the smart key through the activated camera, and setting a position of the driver as a reference point by the vehicle; and

a communication unit for receiving a detected distance of the driver and the vehicle, measured by the PAS,

wherein the communication unit receives information about whether the smart key is recognized from a smart key system (SMK) for transmitting and receiving a signal for recognition of the smart key to and from the smart key in the first region; and

after setting of the reference point and receiving the detected distance, the controller controls at least one of a drive system, a brake system, and a steering system to move forward or backward based on the detected distance or to turn left or right based on a change in a position of the driver in right and left directions with respect to the reference point while the SMK receives a parking signal from the smart key.
