The pulse signal TX transmitted by the vehicle antenna 111 in the direction toward the interior of the vehicle 100 according to the embodiment may include a plurality of pulses in units of ns and the vehicle antenna 111 may include a plurality of pulses Can be transmitted.

When a plurality of pulses are transmitted to the occupant, a plurality of pulses transmitted by the vehicle antenna 111 are reflected from the occupant by the Doppler effect, (RX) having a frequency different from that of the pulse signal (TX). The vehicle antenna 111 according to the embodiment receives the reflected pulse signal (i.e., the reflected pulse signal) from the occupant and determines whether the occupant is present in the vehicle 100 based on the frequency of the reflected pulse signal RX Can be determined. In this way, when the vehicle antenna 111 transmits and receives a pulse signal, the vehicle antenna 111 performs a function of a pulse doppler radar.

6, a data signal can be transmitted around the vehicle 100 in the communication mode and the outdoor mode, and when the remote control device 200 exists within a range where data communication from the vehicle 100 is possible, The vehicle antenna 111 of the vehicle 100 may receive a data signal from the remote control device 200. [

A plurality of vehicle antennas 111a to 111d may be provided and a data signal received by the plurality of vehicle antennas 111a to 111d may be received by the receiving antennas 111a to 111d The strength and reception direction may be different.

The vehicle control unit 120 can estimate the distance between the vehicle 100 and the remote control device 200 based on the reception intensity of the data signal received by the plurality of vehicle antennas 111a to 111d, The direction of the remote control apparatus 200 can be estimated based on the vehicle 100. [ The vehicle control section 120 can estimate the position of the remote control apparatus 200 based on the distance between the vehicle 100 and the remote control apparatus 200 and the direction of the remote control apparatus 200. [

The vehicle control unit 120 can determine whether the remote control device 200 exists in the room of the vehicle 100 or outside the room based on the determined position of the remote control device 200. [

However, the method of determining whether the remote control apparatus 200 exists inside or outside the vehicle 100 is not limited to this. For example, It is determined that the remote control apparatus 200 is in the room when the data signal is received from the remote control apparatus 200 and the data signal is received from the remote control apparatus 200 when the search mode of the vehicle antenna 111 is the outdoor mode It may be determined that the remote control apparatus 200 is outdoors.

Hereinafter, a method of controlling the vehicle 100 according to an embodiment will be described with reference to FIG. 7 is a flowchart of a vehicle control method according to an embodiment. The components of the vehicle 100 described in Fig. 7 are the same as those of the vehicle 100 described above with reference to Figs. 1 to 4, and are described with the same reference numerals.

First, the vehicle control unit 120 determines whether the vehicle 100 is in a closed state after the start of the vehicle 100 is turned off by the user pressing the start button 31 (Fig. 2) and the door 15L (Fig. 2) provided on the driver's seat 18L is opened If it is detected (1110), the operation mode of the vehicle communication unit 120 is changed to the communication mode, and the search mode of the vehicle antenna 112 is changed to the indoor mode (1120).

Next, the vehicle control unit 120 controls the vehicle communication unit 110 to transmit the data signal to the room of the vehicle 100, and the remote control device 200 is installed in the vehicle 100 based on the received data signal (1130).

Specifically, when the vehicle control unit 120 receives the data signal including the authentication information matching the authentication information stored in the vehicle 100, the vehicle control unit 120 determines that the remote control device 200 exists in the room of the vehicle 100 .

On the other hand, when the authentication information included in the data signal is inconsistent with the authentication information stored in the vehicle 100, even if the data signal is not received or the data signal is received, It can be determined that the mobile terminal 200 does not exist.

Then, when it is determined that the remote control apparatus 200 does not exist in the room (NO in 1130), the vehicle control unit 120 changes the operation mode of the vehicle communication unit 120 to the sensing mode (1140). Here, the search mode of the vehicle antenna 111 is still maintained as the indoor mode (1140).

Next, the vehicle control section 120 controls the vehicle communication section 110 to transmit the pulse signal to the room of the vehicle 100, and based on the reflected pulse signal (i.e., the reflected pulse signal) in the room 100 of the vehicle 100 It is determined whether a passenger is present in the vehicle 100 (1150).

The vehicle control unit 120 controls the vehicle notification unit 1160 to notify the presence of the occupant, and accordingly, the vehicle notification unit 130 notifies the presence of the occupant (s) The user can be notified of the presence of the passenger in an audiovisual manner (1160).

On the other hand, when it is determined that there is no occupant in the room ("NO" in 1150), the vehicle control unit 120 controls the door lock unit 140 to lock the door lock of the vehicle 100 (1171) The operation mode of the vehicle communication unit 110 is changed to the communication mode, and the search mode of the vehicle antenna 111 is changed to the outdoor mode (1172). Accordingly, the door lock of the vehicle 100 is locked, and the vehicle communication unit 110 is able to receive the door lock release request signal of the remote control device 200 transmitted outside the vehicle 100.
