Abstract

Disclosed herein is a vehicle that includes 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 at least one of inside or outside of the vehicle through a second frequency band, and to 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 at least one of the position of the user terminal or startup of the vehicle.

First claim

What is claimed is:

1 . 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 at least one of 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 at least one of the position of the user terminal or a startup of the vehicle.

2 . The vehicle according to claim 1 , wherein:
the controller is configured to determine the operation mode based on at least one of whether the user terminal is inside the vehicle, whether the vehicle is started, or whether the door is locked.

3 . The vehicle according to claim 1 , wherein:
when the second communication module is activated, and the position of the user terminal is outside of the vehicle and the vehicle is in a start-off state, the controller is configured to control the second communication module to operate in a first mode for determining the position of the user terminal with respect to the outside of the vehicle.

4 . The vehicle according to claim 1 , wherein:
when the position of the user terminal is inside of the vehicle and the vehicle is in a start-off state, the controller is configured to control the second communication module to operate in a second mode for determining the position of the user terminal with respect to the inside of the vehicle based on a door state.

5 . The vehicle according to claim 1 , wherein:
the controller is configured to control the second communication module to operate in a third mode for detecting a user in the vehicle when the position of the user terminal is inside of the vehicle and the vehicle is a start-on state.

6 . The vehicle according to claim 5 , wherein the controller is configured to:
send the sensing signal to the inside of the vehicle, and control the second communication module to receive the reflected signal corresponding to the sensing signal from the user, and determine a state of the user in the vehicle based on the sensing signal and the reflected signal.

7 . The vehicle according to claim 1 , wherein:
the controller is configured to control the second communication module to operate in a fourth mode for detecting an obstacle outside the vehicle based on a position of the gear lever when the position of the user terminal is inside of the vehicle and the vehicle is a start-on state.

8 . The vehicle according to claim 1 , wherein:
when the position of the user terminal is outside of the vehicle and the vehicle is a start-off state, and when 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 a fifth mode for detecting an intrusion into the vehicle.

9 . 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 activates the second communication module when the user terminal is authenticated.

10 . The vehicle according to claim 1 , further comprising:
a door locking device configured to lock a door or unlock the door; 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 the door when the user terminal is authenticated.

11 . The vehicle according to claim 10 , further comprising:
a starting device configured to turn-on or turn-off the vehicle; 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 turn-on the starting when the position of the user terminal is inside of the vehicle.

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

13 . The vehicle according to claim 1 , wherein:
the second communication module utilizes UWB(Ultra Wide Band).

14 . A controlling method of a vehicle, 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; transmitting a sensing signal, through a data channel having a second frequency bad, to at least one of an inside or an outside of the vehicle, and 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 at least one of the position of the user terminal or a startup of the vehicle.

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

16 . The method according to claim 14 , wherein performing the operation mode comprises:
when the second communication module is activated, and the position of the user terminal is outside of the vehicle and the vehicle is in a start-off state, operating in a first mode for determining the position of the user terminal with respect to the outside of the vehicle.

17 . The method according to claim 14 , wherein performing the operation mode comprises:
when the position of the user terminal is inside of the vehicle and the vehicle is in a start-off state, operating in a second mode for determining the position of the user terminal with respect to the inside of the vehicle based on a door state.

18 . The method according to claim 14 , wherein:
operating in the operation mode comprises operating in a third mode for detecting a user in the vehicle when the position of the user terminal is inside of the vehicle and the vehicle is a start-on state.

19 . The method according to claim 14 , wherein:
operating in the operation mode comprises operating in a fourth mode for detecting an obstacle outside the vehicle based on a position of the gear lever when the position of the user terminal is inside of the vehicle and the vehicle is a start-on state.

20 . The method according to claim 14 , wherein performing the operation mode comprises:
when the position of the user terminal is outside of the vehicle and the vehicle is a start-off state, and when a door is changed from an unlocked state to a locked state, operating in a fifth mode for detecting an intrusion into the vehicle.
