The interface device 200 may collect voice information through the input unit 220 in the sleep mode (S1100). When the vehicle operation is stopped, the interface device 200 operates a sleep mode to supply power to the input unit and collect voice information.

The voice information may include various information such as whether the voice signal is detected, the frequency of the voice signal, the strength of the voice signal, the location at which the voice signal is detected, and the time for which the detection of the voice signal is continued.

The interface device 200 may determine whether the characteristics of the collected voice information satisfy a predetermined condition (S1200). When the characteristics of the collected voice information satisfy a predetermined condition, the interface device 200 may determine that a person or an animal exists in the vehicle.

The predetermined condition may be, for example, whether a voice signal is detected. When the voice signal is detected inside the vehicle, the interface device 200 may determine that a person or an animal exists inside the vehicle.

The predetermined condition is, for example, whether the frequency of the audio signal is within a predetermined range. The predetermined range is a frequency range of sounds uttered by humans or animals. Therefore, when the voice signal within the frequency range of the human or animal's vocal sound is detected, the interface device 200 may determine that a human or animal exists in the vehicle.

The predetermined condition is, for example, whether the strength of the audio signal is within a predetermined range.

Accordingly, when the voice signal within the sound intensity range of the human or animal's utterance is detected, the interface device 200 may determine that a human or animal exists in the vehicle.

The predetermined condition is, for example, that the time for which the detection of the audio signal continues is longer than the predetermined time. Here, the duration of the voice signal may be the duration of one voice signal. For another example, the duration of the voice signal may be the total duration at which a plurality of voice signals are detected.

If the first audio information satisfies a predetermined condition, the interface device 200 determines that there is a high possibility that a person or an animal exists inside the vehicle, and collects the second audio information for accurate determination.

The interface device 200 may operate the input unit based on the first voice information, and then collect the second voice information.

The first voice information may include information about a location and direction in which the first voice information is detected. The interface device 200 may change such that the microphone 222 as an input unit faces the receiver of the microphone 222 in a direction in which the first voice signal is detected. The interface device 200 may increase the sensitivity to the location where the first voice signal is detected. When there are multiple microphones 222, the interface device 200 may manipulate the direction and sensitivity of the microphone 222 in which the signal having the largest first voice signal is detected.

Thereafter, the interface device 200 may detect the second voice signal through the manipulated input unit. As a result, the interface device 200 can increase the reliability of the determination as to whether a person or an animal exists in the vehicle, and can prevent the provision of an indiscriminate alarm.

The interface device 200 may determine whether the characteristic of the second voice information satisfies a predetermined condition (S2400). If the characteristic of the second voice information satisfies a predetermined condition, the interface device 200 may determine that there are humans or animals in the vehicle. That is, the interface device 200 may determine whether a person or an animal exists inside the vehicle based on the first voice information and the second voice information.

The predetermined conditions may be the predetermined conditions described above in step S2200. According to an embodiment, the frequency range of the voice signal in step S2400 and the frequency range of the voice signal in step S2200 may be different. The intensity range of the voice signal in step S2400 and the intensity range of the voice signal in step S2200 may be different. The duration of the voice signal in step S2400 and the duration of the voice signal in step S2200 may be different.

For example, the voice signal frequency range of step S2400 may be a narrower range to be closer to the human or animal frequency than the voice signal frequency range of step S2200. As a result, the accuracy of judgment through the second voice information can be increased. Likewise, the intensity range of the voice signal in step S2400 may be a narrower range to be closer to the intensity of the voice signal of a human or animal than the intensity range of the voice signal in step S2200. In addition, the duration of the voice signal in step S2400 may be shorter than the duration of the voice signal in step S2200. Accordingly, the interface device 200 may urgently provide an alarm in response to a shorter duration voice signal.

Thereafter, the interface device 200 may provide an alarm through an alarm mode (S2500). Step S2500 may include the above-described contents in step S1300.

The interface device 200 may determine whether the characteristics of the voice information satisfy a predetermined condition (S3200). Step S3200 may include the above-described contents in step S1200.

Thereafter, the interface device 200 may collect image information through the camera 224 (S3300). If the characteristics of the voice information satisfy a predetermined condition, the interface device 200 determines that there is a high possibility that a person or an animal exists in the vehicle, and collects image information through the camera 224 for accurate determination. .

The interface device 200 may set a space for photographing the camera 224 based on the characteristics of the voice information. For example, the interface device 200 may change a photographing direction of the camera 224 toward a location where the voice information is received, or may photograph a location where the voice information is received through a zoom-in and out function.

The interface device 200 may determine whether the characteristic of the image information satisfies a predetermined condition (S3400). If the characteristic of the image information satisfies a predetermined condition, the interface device 200 may determine that a person or an animal exists inside the vehicle. That is, the interface device 200 may determine whether a person or an animal exists in the vehicle based on the image information and the audio information.

The control unit 260 of the interface device 200 may include an image processing unit, and analyze image information acquired through the camera 224 to determine whether a person or an animal exists in the vehicle. For example, a predetermined condition may be that motion is detected in an image. The controller 260 may determine that the movement in the image is caused by a person or an animal inside the vehicle.

For another example, the predetermined condition may be a case where the acquired image or image is different from the reference image or reference image acquired when the vehicle is empty. When compared to a reference image or a reference image when the vehicle is empty, when another object is included in the acquired image or image, the interface device 200 may determine that there are people or animals in the vehicle. In particular, the interface device 200 may determine whether there is an object different from the reference image or the reference image in an area corresponding to the seat of the vehicle.

Thereafter, the interface device 200 may provide an alarm through an alarm mode (S3500). Step S3500 may include the above-described contents in step S1300.
