[0001] Apparatus for collision testing of vehicle [

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle collision test apparatus, and more particularly, to a collision test apparatus for precisely setting a situation similar to a case where a vehicle is driven in an actual traffic situation and detecting a shock to a pedestrian and a motion of a pedestrian To a collision test apparatus for a vehicle.

The vehicle running test system is a test to test various performance of a vehicle by replaying situations similar to various actual traffic situations. It is used for testing and evaluating vehicle performance such as braking ability evaluation, acceleration running test, exhaust gas amount measurement, Lt; / RTI > In recent years, it is also used to test driving by a driving robot and unmanned driving using a GPS system.

A device is being developed to traverse a vehicle path of a human dummy pedestrian to simulate a situation similar to many actual traffic situations.

On the other hand, a collision test of a vehicle is for checking and evaluating a situation occurring when a vehicle collides with an obstacle or the like while driving. For example, when a vehicle collides with an obstacle, Or a test that measures the degree of pedestrian injury when a vehicle collides with a pedestrian.

A test apparatus for colliding a vehicle is known as a test apparatus for running the vehicle on a predetermined guide rail and colliding or colliding to the side laterally on the wall. This collision test system is a safety performance device that tests the safety of the vehicle by actually colliding the vehicle against the wall. In order to measure the amount of impact and the impact portion received by the passenger at the time of collision, a driver's pile of the human model is seated in the seat, To collide with the vehicle.

Or a collision with a pedestrian. The collision test apparatus collides a pedestrian pile with a vehicle while moving the pedestrian pile on the path of the vehicle, thereby detecting an impact amount and a shock portion received by the pedestrian Can be measured.

Through these tests, it is possible to obtain an appropriate value for the impact amount for operating the air bag, the structure of the seat belt, the bonding strength, and the like. Further, it is possible to secure data that can more stably change the structure of a vehicle such as a bumper or a frame.

However, a pedestrian pile used in a device used for a vehicle running test or a device for measuring when a vehicle collides with a pedestrian is conventionally used as a simple fixed model, There is a problem that it is difficult to precisely grasp the impact amount or the impact area which is difficult or when the pedestrian collides.

The vehicle 10 is prevented from further colliding with the impact absorbing portion 90 and entering the side of the transverse sidewalk 6 when the vehicle 10 further moves beyond the stopping point to the transverse sidewalk 6 side by a certain distance or more.

On the other hand, when the vehicle 10 reaches the stop point, the dummy 30 located on the crosswalk 6 is collided by the vehicle 10, and the impact sensor 57 built in the dummy 30 collides with the vehicle 10 10 and transmits the sensed information to the transport driving unit 70. [ The conveyance driving unit 70 releases the connection between the winch motor 44b and the winding roller 44c when the impact information detected by the impact sensor 57 is equal to or higher than the reference value, And turns the winding roller 44c into a state in which it can be freely loosened so as to be blown off or away from the crosswalk 6. In addition, the impact information sensed by the impact sensor 57 is displayed on the display 100.
