4 is a flowchart showing a vehicle warming method according to FIG.

The vehicle 100 senses the smart key 200. For example, the LF signal and the RF signal may be applied to the vehicle 100 as a method of sensing the smart key 200. [ The vehicle 100 can sense the smart key 200 through the LF transmitter and the RF receiver of the vehicle communication unit 110. [ Vehicle 100 transmits an LF signal via an LF transmitter and receives an RF signal generated in response to an LF signal from smart key 200 via an RF receiver. When the RF signal received through the RF receiver matches the authentication signal, the vehicle 100 determines the smart key 200 as the smart key 200 corresponding to the vehicle 100. The vehicle 100 calculates a distance D between the vehicle 100 and the smart key 200 based on the LF signal and the received RF signal. The distance D between the vehicle 100 and the smart key 200 can be calculated based on the speed of the LF signal and the RF signal and the time taken for the vehicle 100 to receive the RF signal after sending out the LF signal (410).

The vehicle 100 sets the distance by which the vehicle hitting unit 160 is initially operated by the proximity of the smart key 200 to the reference distance R. [ That is, the reference distance R is a maximum distance at which the vehicle 100 can recognize the proximity of the smart key 200 and operate the vehicle heating portion 160.

The vehicle 100 confirms whether the distance D between the vehicle 100 and the smart key 200 is equal to or less than the reference distance R. [ That is, the vehicle 100 confirms whether the smart key 200 has entered the range corresponding to the reference distance R or less (415).

If the distance D between the vehicle 100 and the smart key 200 falls below the first distance R1, the vehicle 100 confirms whether the indoor temperature of the vehicle 100 is below a predetermined reference temperature (420).

If the room temperature of the vehicle 100 exceeds a predetermined reference temperature, the vehicle 100 does not operate the vehicle heating section 160. [ If the indoor temperature of the vehicle 100 falls below a predetermined reference temperature, the vehicle 100 activates the vehicle heating portion 160 (425).

After the vehicle heating unit 160 is operated 425, whether the distance D between the vehicle 100 and the smart key 200 continuously falls below the reference distance R is checked. That is, it is determined whether the smart key 200 is continuously present within a range below the reference distance R from the vehicle 100 (430).

If the distance D between the vehicle 100 and the smart key 200 is maintained to be equal to or less than the first distance R1, the vehicle 100 continuously operates the vehicle heating portion 160 ).

If the distance D between the vehicle 100 and the smart key 200 exceeds the reference distance R after the vehicle hitting section 160 is operated 425, Is not located in a range corresponding to the reference distance R or less. Accordingly, the vehicle 100 stops the operating vehicle heating portion 160 (440).

After the vehicle heating portion 160 is operated by the embodiments of the present invention, the vehicle 100 can stop the operation of the vehicle heating portion 160 according to the room temperature and the remaining battery level of the vehicle 100. [ The vehicle 100 can stop the operation of the vehicle heating portion 160 according to the room temperature of the vehicle 100.
