Abstract: Proposed are a system and a method for position estimation and direction recognition between objects through a cooperative intelligent transport systems (C-ITS) linkage in a vehicle to everything (V2X) communication environment. The system may include an infrastructure information receiver configured to receive infrastructure information from an infrastructure, and an object position determination processor configured to determine a position of equipment in use. The system may also include an object position and path prediction processor configured to predict a future position and a movement path of the equipment in use and an object information transceiver configured to exchange information on the equipment with another object. The system may further include an object and surrounding situation recognition and determination processor configured to recognize an object and a surrounding situation and determine whether a dangerous situation exists by using information acquired through the C-ITS linkage.

According to an embodiment, a road condition determination method may acquire sensor data, may recognize objects by analyzing the acquired sensor data, may receive sensor data and object recognition results from external terminals, may determine reliability on the received object recognition results and sensor data, and may determine road conditions, based on the acquired sensor data and object recognition results and object recognition results and sensor data which are given reliability.

Abstract: There is provided a cooperative driving control method based on a vehicle security status. The cooperative driving method according to an embodiment includes: identifying a security status of a cooperative driving target vehicle; determining a cooperative driving strategy according to the identified security status; and controlling driving according to the determined cooperative driving strategy. Accordingly, cooperative driving may be performed or excluded based on a security status of a target vehicle, so that an accident may be prevented from being caused by cooperative driving with a problematic vehicle, and safety of a driver and an occupant may be guaranteed.

Abstract: An apparatus for controlling traveling of vehicles in a roundabout is proposed. The apparatus may include an input unit configured to receive classification information on a roundabout which a traveling vehicle approaches and surrounding environment information, and a memory in which a vehicle traveling control program for the roundabout is stored. The apparatus may also include a processor configured to execute the program, in which the processor determines a traveling negotiation target according to the classification information on the roundabout, the surrounding environment information, and route information on the traveling vehicle, and controls a traveling behavior of the vehicle in the roundabout according to a traveling negotiation result.

The pixel driving circuit includes a driving switching element connected in series between high and low-level voltage supply lines, together with the light emitting element, a first switching element for connecting a data line and a first node connected to a gate of the driving switching element in response to a first scan signal, a second switching element for connecting an initialization voltage supply line and a second node connected to a source of the driving switching element in response to a second scan signal, and a third switching element for connecting the high-level voltage supply line and a drain of the driving switching element in response to an emission signal.

Abstract: An extrusion die using a shock-absorbing pad and a method for manufacturing an extrusion. A shock-absorbing pad is inserted between a material to be processed and a die such that the shock-absorbing pad is deformed during extrusion to form an optimal die half angle, thereby efficiently extruding the material to be processed. The extrusion die for extruding the material to be processed includes a container for accommodating a material to be processed, a die which is mounted on the front of the container, and which has, in the center thereof, a die hole that is a path through which the material to be processed is extruded, a shock-absorbing pad inserted between the material to be processed and the die, and a ram for pressing the material to be processed.
