Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a diagram showing the overall configuration of an autonomic braking test system according to an embodiment of the present invention.

An autonomous braking test system according to an embodiment of the present invention includes a vehicle detection sensor 100, a control jig 110, a plate 120, and a dummy 130. [

The vehicle detection sensor 100 senses a vehicle in operation and transmits information on the time of sensing the vehicle to the control jig 110 so that the control jig 110 controls the movement of the plate 120 and the dummy 130 .

2 is a view showing an example of the overall structure of the vehicle detection sensor 100 and its support.

For example, as shown in FIG. 2, the vehicle detection sensor 100 may include a first vehicle detection sensor 200 and a second vehicle detection sensor 210 separated by a predetermined interval (for example, 1 to 2 m) Information about the time when the first vehicle detection sensor 200 and the second vehicle detection sensor 210 sense the moving vehicle can be transmitted to the control jig 110. Alternatively, the first vehicle detection sensor 200 located in the approaching direction of the vehicle senses the vehicle, measures the time required for the second vehicle detection sensor 210 to detect the vehicle, and controls information on the measured time Jig 110 as shown in FIG.

When the control jig 110 receives information on the time when the vehicle is sensed by the vehicle detection sensor 100, the control jig 110 outputs the received time information and the distance information between the first vehicle detection sensor 200 and the second vehicle detection sensor 210 The speed of the vehicle being driven is calculated. Then, the estimated time of arrival of the vehicle at the predicted collision point is predicted using the calculated speed.

The collision predicted point is a point at which the vehicle under running collides with the plate 120 and the dummy 130 controlled by the control jig 110 and calculates the distance from the vehicle detection sensor 100 to the expected collision point Estimate the arrival time of the vehicle using the speed.

The control jig 110 controls the movement of the plate 120 and the dummy 130 so that the dummy 130 attached to the upper end of the plate 120 and the plate 120 is positioned in the traveling path of the vehicle Control the movement.

FIG. 3 shows the overall structure of the plate 120 and the dummy 130. FIG.

The plate 120 may be composed of a rectangular plate, and the dummy 130 is attached to the upper end of the plate 120. The dummy 130 may be in the form of a human and the arm portion of the dummy 130 may move when the plate 120 moves.

FIGS. 4A, 4B and 4C show the structure of the lower end of the plate 120. FIG.

As shown in FIG. 4A, the lower end of the plate 120 may move with wheels attached thereto or may be attached with a ball bearing attached to the lower end of the plate 120 as shown in FIG. 4B. At this time, the plate 120 can move along a rail or a groove provided on the floor.

According to another embodiment of the present invention, the plate 120 may be moved by attaching acetal to the lower end of the plate 120 as shown in FIG. 4C. When the acetal is attached to the lower end of the plate 120, the dummy 130 can be positioned at a lower height than the plate 120 to which the wheel or the ball bearing is attached (without providing a groove on the floor) So that the test can be performed in an environment similar to an actual collision environment.

According to another embodiment of the present invention, the plate 120 may be composed of a first plate and a second plate. That is, when the dummy 130 is in the shape of a person, one foot portion of the dummy 130 is attached to the first plate and the second plate, and when a command to move the plate 120 is input, The second plate can be moved alternately at a constant speed to create a situation in which an actual person moves while walking.

The control jig 110 controls the movement of the plate 120 having the above-described structure to make a situation in which the dummy 130 is expected to collide with the vehicle so as to test the performance of the autonomous braking device of the vehicle being driven .

At this time, according to another embodiment of the present invention, the control jig 110 may include a dummy speed setting unit, a collision position setting unit or a display unit.

The dummy speed setting unit sets the speed of the moving dummy 130 and controls the moving times of the plate 120 and the dummy 130 by using the speed of the set dummy 130 and the expected arrival time of the vehicle during driving . This makes it possible to test autonomous braking of the vehicle for objects moving at various speeds.

The collision position setting unit allows the dummy 130 to set a position at which the dummy 130 collides with a running vehicle. For example, the collision position setting unit sets the collision position of the front right side, the front center, or the front left side of the vehicle, This allows autonomous braking to be tested in the presence of objects in various directions.

The display unit displays information (e.g., speed information, estimated arrival time information, etc.) of the vehicle being driven, information of the plate 120 and the dummy 130 (e.g., moving speed information, collision position information, etc.) So that information on the dummy 130 can be received. At this time, the setting of the speed and the like of the dummy 130 can be inputted and set by touching.

The control jig 110 uses the information of the vehicle received from the vehicle detection sensor 100 and information about the set dummy 130 so that the dummy 130 is positioned at the estimated traveling time of the vehicle So that the autonomous braking of the vehicle can be tested.

5 to 8 show examples of autonomous braking test of a vehicle by an autonomic braking test system according to an embodiment of the present invention.

As shown in FIGS. 5 to 6, the plate and the dummy are located at the starting point before the vehicle starts or before passing through the vehicle detection sensor. When it is confirmed that the vehicle has passed the vehicle detection sensor, .

The plate and the dummy move at a constant speed and move to the vehicle's traveling path at the expected arrival time of the vehicle. At this time, as shown in FIG. 7, it is possible to test the autonomous braking device of the vehicle in various collision situations by controlling the movement of the dummy even though it is controlled by the control jig including the emergency stop and manual start button .

8 shows an embodiment in which the autonomous braking system further includes a secondary vehicle detection sensor 810, a collision detection sensor 820 in addition to the above-described vehicle detection sensor (primary vehicle detection sensor 800 in FIG. 8).

8, a secondary vehicle detection sensor 810 and a collision detection sensor 820 may be further included between the primary vehicle detection sensor 800 and the testing point 830, 820 are located within a certain distance from the testing point 830 (e.g., a distance that can detect a collision at the testing point 830).

The secondary vehicle detection sensor 810 may be configured in the same manner as the primary vehicle detection sensor 800, and detects the moving vehicle and transmits time information according to the vehicle detection to the control jig. The control jig calculates the speed of the vehicle according to the time information received from the secondary vehicle detection sensor 810, and checks the validity of the calculated speed of the vehicle to control the movement of the dummy.

For example, the speed (second speed) of the vehicle according to the time information received from the secondary vehicle detection sensor 810 is compared with the speed (first speed) of the vehicle according to the time information received from the primary vehicle detection sensor 800 And confirms whether the second speed is equal to the first speed or is within a predetermined range from the first speed. If it is determined that the second speed is equal to the first speed or is within the predetermined range, it is considered effective to control the movement of the dummy according to the first speed. Therefore, the movement control of the dummy is performed according to the moving speed and the moving time of the set dummy . If the second speed is out of the effective range, even if the dummy movement control according to the first speed is performed, proper testing can not be performed, so that the movement of the dummy can be stopped and a new test can be performed.

The collision detection sensor 820 is located within a predetermined distance from the testing point 830 and detects whether the vehicle collides with the dummy. If the autonomous braking system of the vehicle normally operates, the vehicle is stopped before the collision, but if not, the collision may occur. If the collision detection sensor 820 detects a collision, the control jig transmits a collision detection signal to the control jig. Upon receiving the collision detection signal, .

The foregoing description is merely illustrative of the technical idea of the present invention and various changes and modifications may be made without departing from the essential characteristics of the present invention. Therefore, the embodiments described in the present invention are not intended to limit the scope of the present invention, but are intended to be illustrative, and the scope of the present invention is not limited by these embodiments. It is intended that the present invention cover the modifications and variations of this invention provided they come within the scope of the appended claims and their equivalents, which fall within the scope of the present invention as claimed.
