7. The vehicle according to claim 1 , wherein when the position of the user terminal is outside of the vehicle, the vehicle is a start-off state, and a door is changed from an unlocked state to a locked state, the controller is configured to control the second communication module to operate in the fifth mode for detecting an intrusion into the vehicle.

8. The vehicle according to claim 1 , wherein the controller is configured to authenticate the user terminal when the first communication module receives the search signal and to activate the second communication module when the user terminal is authenticated.

9. The vehicle according to claim 1 , further comprising:

a door locking device;

wherein the controller is configured to authenticate the user terminal when the position of the user terminal is within a predetermined region, and to control the door locking device to unlock a door of the vehicle when the user terminal is authenticated.

10. The vehicle according to claim 9 , further comprising:

a starting device;

wherein the controller is configured to determine whether the position of the user terminal is inside of the vehicle when the state of the door is changed from an open state to a closed state after the door is unlocked, and to control the starting device to start the vehicle when the position of the user terminal is inside of the vehicle.

11. The vehicle according to claim 1 , wherein the first communication module utilizes BLE (Bluetooth Low Energy).

12. A vehicle comprising:

a first communication module configured to receive a search signal of a user terminal through a data channel having a first frequency band;

a second communication module configured to send a sensing signal to an inside or an outside of the vehicle through a second frequency band, and receive a reflected signal corresponding to the sensing signal; and

a controller configured to:

wake up the second communication module when the first communication module receives the search signal,

determine a position of the user terminal based on the sensing signal and the reflected signal, and

control the second communication module to operate in an operation mode that is determined based on the position of the user terminal or a startup of the vehicle, the operation mode for detecting an obstacle outside the vehicle based on a position of a gear lever when the position of the user terminal is inside of the vehicle and the vehicle is a start-on state.

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

receiving, with a first communication module, a search signal of a user terminal through a data channel having a first frequency band;

waking-up a second communication module when the first communication module receives the search signal, wherein the second communication module utilizes UWB (Ultra Wide Band);

transmitting a sensing signal, through a data channel having a second frequency band, to an inside or an outside of the vehicle;

receiving a reflected signal corresponding to the sensing signal;

determining a position of the user terminal based on the sensing signal and the reflected signal; and

operating in an operation mode that is determined based on the position of the user terminal or a startup of the vehicle, wherein the operation mode includes a first mode for determining the position of the user terminal with respect to the outside of the vehicle, a second mode for determining the position of the user terminal with respect to the inside of the vehicle, a third mode for detecting a user in the vehicle, a fourth mode for detecting an obstacle outside the vehicle, and a fifth mode for detecting an intrusion into the vehicle.

14. The method according to claim 13 , wherein operating in the operation mode comprises determining the operation mode based on whether the user terminal is inside the vehicle, whether the vehicle is started, or whether a door of the vehicle is locked.

15. The method according to claim 13 , wherein performing the operation mode comprises, when the second communication module is activated, the position of the user terminal is outside of the vehicle, and the vehicle is in a start-off state, operating in the first mode for determining the position of the user terminal with respect to the outside of the vehicle.
