Claims (5)

1. A dummy (10) having the form of a person or a companion animal, or the form of a person riding a two-wheeled vehicle such as a bicycle; A dummy table (20) in which the above dummy is detachably installed; A transfer rail (30) installed in a dummy movement path including a crosswalk to move the dummy table along the dummy movement path; and A pedestrian dummy driving device characterized by including a control means (40) that controls the movement speed and direction of the dummy by controlling the drive of the above-mentioned transfer rail.
2. In paragraph 1, A pedestrian dummy driving device characterized by the fact that a magnet (20m) is installed on the dummy table, and the dummy is fixed to the dummy table by pulling a steel plate or magnet installed on the bottom of the dummy, and the dummy is separated from the magnet when an impact is applied to the dummy from the outside, thereby preventing the dummy from being damaged.
3. In paragraph 1, A pedestrian dummy driving device characterized by having a rotation means (21) installed at the bottom of the above dummy table to change the direction of the dummy.
4. In paragraph 1, The above-mentioned transfer rail is installed inside a moving bit (31) excavated in the road along the dummy's movement path and is characterized by being composed of a conductor rail.
5. In paragraph 4, A water level sensor (32) is installed inside the above-mentioned moving bit to detect when water flows into the moving bit, and A pedestrian dummy driving device characterized by having a drainage pump (33) for draining water inside the moving bit and a blower (34) for blowing out sand, soil, and rainwater flowing into the moving bit further installed inside the moving bit.

Description

Pedestrian Dummy Driving Device The present invention relates to a pedestrian dummy driving device, and more specifically, to a pedestrian dummy driving device capable of stable movement by implementing dummy rotation and variable transport speed according to the driving direction. Furthermore, the present invention relates to a pedestrian dummy driving device that uses corrosion-resistant materials, secures drainage facilities along the movement path to respond to the external environment, and selects key components for which spare parts are easily available, thereby enabling real-time repair in the event of a failure. Furthermore, the present invention relates to a pedestrian dummy driving device having a stable redundancy structure capable of automatic and manual testing, as well as facilitating error recovery when a problem occurs in the system and maintaining a minimum testing function. A dummy driving device is a system designed to reproduce situations that may occur at crosswalks on roads. It is used to simulate unexpected situations involving pedestrians and bicycles (including jaywalking) that occur when a vehicle is actually driving, and to implement a vehicle control system that responds to these situations. In other words, a vehicle driving test device including a dummy driving device can check the responsiveness of the vehicle's emergency braking system according to the situation through repeated testing. The dummy driving device has the advantage of allowing flexible operation to prepare for various situations by enabling the setting of the dummy's direction, speed, and timing of movement. Various technologies have been developed for dummy driving devices to contribute to increased test productivity by simplifying test procedures and supporting auxiliary equipment for efficient system operation, using industrially standardized parts capable of self-maintenance, and providing appropriate safety devices and recovery functions, as examples of which are Patent Documents 1 to 4. Patent Document 1 is a driving test dummy used in a vehicle driving test system, comprising: a torso; left and right lower limbs, the upper portions of which are coupled to the torso to rotate in the front-rear direction around the torso; left and right upper limbs, which are positioned above the left and right lower limbs and have one end coupled to the torso; and a driving base coupled to the lower portions of the left and right lower limbs and which rotates the left and right lower limbs while moving in one direction. Patent Document 2 comprises: a collision part to which a load is applied by a collision body; a variable stiffness joint to which the load is transmitted and which simulates a collision response to a joint of the human body; and a link formed to extend a predetermined amount in the longitudinal direction and transmit the load to the variable stiffness joint; wherein the variable stiffness joint comprises: an outer disk that is rotationally constrained; and an inner disk that rotates upon the transmission of the load. and a plurality of elastic bodies each connected between an outer disk and an inner disk to elastically support the rotation of the inner disk, and spaced apart at a predetermined interval along the outer circumference of the outer disk or the inner disk; wherein the outer disk has a plurality of first elastic body mounting portions spaced apart at a predetermined interval along the outer circumference and exposed to the outside, and the inner disk has a plurality of second elastic body mounting portions spaced apart along the outer circumference and exposed to the outside corresponding to the plurality of first elastic body mounting portions, and the elastic body is a simplified collision dummy for human collision testing formed such that one end is detachably connected to the first elastic body mounting portion and the other end is detachably connected to the second elastic body mounting portion, and the link is formed to be extendable in the longitudinal direction. Patent Document 3 comprises: a traction plate capable of installing a dummy; a traction belt fixed to both ends of the traction plate to move the traction plate in a straight line; a drive unit equipped with a drive motor and a drive pulley inside to drive the traction belt, and connected to a drive controller and an external power source; and a driven unit positioned at a predetermined distance from the drive unit and equipped with driven pulleys at regular intervals inside to allow the traction belt to pass through, wherein the traction plate has: a belt fixing part capable of fixing the traction belt installed at each end, and the belt fixing part is installed such that one side is connected by a hinge and can spread out around the hinge, and a pair of clamping blocks capable of fixing the traction belt are formed on the inner surface with a tooth groove corresponding to the tooth provided on the traction belt.
