Angle information formed by the camera and the user may include angle information formed by the field of view of the camera and the user's feet.

User's height = A+B*tan(C - tan-1(A/B))

For example, when the height of the camera of the vehicle is 140 cm, the user is 1.2 m away from the tailgate 120, and the angle at which the camera 140 recognizes the user is 60 degrees, the height of the camera 140 Since the angle between the horizontal line and the ground is tan-1 (140/120), it is 49.4 degrees, and the angle between the horizontal line at the height of the camera 140 and the user's head is 60-49.4 = 10.6 degrees. Since the length from the location of the camera 140 to the user's head is 120*tan 10.6˚ = 22.5 cm, the user's height is 140 + 22.5 = 162.5 cm.

The processor 170 may adjust the opening height of the tailgate 120 lower in multiple stages (H2, H3, H4, H5) from the maximum opening height (H1) of the tailgate 120 as the user's height decreases.

A height ratio based on the maximum open height for each range of keys is previously stored in the memory 171, and at this time, the processor 170 checks the range to which the key belongs based on information on the user's key, and determines the range corresponding to the identified key range. The height ratio can be checked and the opening height of the tailgate can be adjusted based on the checked height ratio.

The processor 170 may also check vehicle body tilt information and acquire information on the opening height of the tailgate 120 based on the checked vehicle body tilt information and the user's height information.

The user's key information may be user key information stored in response to user recognition, or may be user key information acquired by the camera 140 .

As shown in FIG. 6, when the height of the camera is A, the distance between the user and the tailgate is B, and the angle at which the camera recognizes the user is C, the user's key information can be obtained by the following equation .

User's height = A+B×tan(C - tan-1(A/D))/((tan(90-tilt angle)˚+tan(C - tan-1(A/D))×cos(90- Inclination angle)˚)

D = B + A×tan(inclination angle)˚

The distance information between the tail gate 120 and the user may be distance information between the camera 140 and the user or distance information between the rear panel 114 and the user.

For example, the height of the camera 140 of the vehicle is 140 cm, the distance of the user from the tailgate 120 is 1.2 m, the inclination angle (i.e., inclination) is 30 degrees, and the angle C between the camera 140 and the user is 50 degrees. When ˚, D is 120+140×tan30˚ = 200.8 cm, and the angle from the direction in which the camera 140 is horizontal to the road surface to the road surface is tan-1(140/200.8) = 34.9˚.

The angle from the direction in which the camera 140 is horizontal to the road surface to the user's head is 50 - 34.9 = 15.1 degrees.

Accordingly, the length E from the position of the camera 140 to the user's head is 120×tan15.1°/((tan60°+tan15.1°)×cos60°) = 32.39.

That is, the user's height is 140+32.35 = 172.39 cm.

The processor 170 may control the motor 135 of the opening/closing device to adjust the opening height of the tailgate 120 based on the user's key information and tilt information.

The processor checks the target rotational speed corresponding to the opening height of the tailgate, checks the rotational speed detected by the first detection unit during operation of the motor, compares the checked rotational speed with the target rotational speed, and checks the rotational speed corresponding to the target rotational speed. When it reaches, the operation of the motor 135 is stopped and controlled.

The processor 170 may adjust the opening height of the tail gate lower in multiple stages from the maximum opening height as the slope of the road surface increases.

As shown in FIG. 7 , the processor 170 may adjust the opening height of the tail gate at a lower height ratio on the uphill slope than on the downhill slope when the same slope is present. That is, the processor 170 may adjust the opening height of the tail gate to be lower on an uphill slope than on a downhill slope when the slope is the same.

The processor 170 may adjust the opening height of the tailgate lower in multiple stages (H2, H3, H4, H5) from the maximum opening height (H1) of the tailgate as the user's height decreases and the slope of the road increases. there is.

The height ratio to the maximum height matched for each key range and inclination range is previously stored in the memory 171, and at this time, the processor 170 determines the range to which the height and inclination ranges belong based on the user's height information and inclination information. The height ratio corresponding to the checked height range and tilt range is checked, and the opening height of the tailgate can be adjusted based on the checked height ratio.

In this way, by adjusting the opening height of the tailgate in response to the user's key, the user's hand can touch the switch of the tailgate when the user's arm is extended, so that the tailgate can be easily closed.

When it is determined that the command to open the tail gate 120 is received, the processor 170 simultaneously obtains user key information through the camera 140 and communicates with the remote controller 2, and when the remote controller 2 is recognized first, the processor 170 Recognizing that the driving user is about to open the tailgate 120, stop acquiring user key information through the camera 140 and immediately control the opening of the tailgate 120, based on the recognized user's key information. Gate opening can be controlled.

When it is determined that communication with the remote controller 2 is impossible within a standard time from the time of detection of a person, the processor 170 determines that a person other than the driver is attempting to open the tailgate, and continuously obtains key information through the camera 140. and when key information is obtained through the camera 140, the opening of the tailgate 120 is controlled, but the motor 135 of the opening/closing device is controlled to open the tailgate up to the opening height of the tailgate corresponding to the acquired key information. do.

The processor 170 maintains control of the opening height of the tail gate 120 based on the acquired key information even if a user changes after opening the tail gate 120 .

As another example, the processor 170, when communication with the terminal 3 located outside the vehicle is performed, based on the GPS information of the terminal 3 or the received signal strength by communication with the terminal 3 After confirming the location information and determining that the terminal 3 is located at the rear of the vehicle based on the checked location information of the terminal 3, the identification information of the terminal 3 is checked and based on the identified identification information of the terminal 3 Thus, a user located at the rear of the vehicle can be recognized.

In this case, the processor 170 may control the opening height of the tail gate based on the user's body information recognized through the terminal 3 .

The processor 170 checks and stores the opening height of the tailgate when the on signal is received through the switch for a preset time or more, and controls opening of the tailgate based on the stored opening height of the tailgate when a command to open the tailgate is received. can do.

When the tail gate opening command is received, the processor 170 checks the slope information of the road surface, adjusts the stored tail gate opening height based on the checked road surface slope information, and adjusts the tail gate opening height based on the adjusted tail gate opening height. You can control the opening.
