  • 본 연구는 최근 논란이 되고 있는 '저탄소차 협력금제도'에 대해 살펴보고자 한다. 제도 도입의 취지와 목적, 필요성 등을 통해 자동차 산업 발전을 위한 대안은 무엇인지 제시하고자 하였다. 저탄소차 협력금제도의 도입은 차량구입비용에 큰 변화를 가져옴으로써 차량구매관행을 크게 변화시킬 수 있으며, 이를 통해 차량에서 배출되는 온실가스의 감축 효과를 기대할 수 있을 것으로 예상된다. 그러나 제도의 성공적 정착을 위해서는 무엇보다도 국민들이 공감할 수 있는 적절한 수준에서 보조금-부담금 구간 설정이 이루어져야 할 것이다. 또한 제도 시행 이전에 자동차 관련 기존 세제에 대한 조정, 부담금의 분할 징수 등의 방안에 대해서도 충분한 검토가 있어야 할 것으로 여겨진다. 자동차 제작사의 경우 제도시행 시점까지 수입차와 동등한 수준의 이산화탄소 배출량을 기록할 수 있도록 기술개발에 최선을 다해야 할 것이며, 정부 역시 이러한 노력에 대한 지원을 강화해야 할 것이다.

  • It is often thought that because no-start motor vehicles cannot start an engine, a fire cannot occur for motor vehicle causes. However, although the engine cannot start up, some parts may be live with electricity if a battery is connected. If the parts have problems, a fire can occur. This study analyzed the causes of fires occurring when a motor vehicle was loaded onto a tow truck to service no-start. It is suggested that no-start motor vehicles should separate a battery terminal to prevent a fire. And this fire is related to automotive products liability.

  • European offset impact analysis of an electric vehicle was done using the robust design method. Section properties of some of the vehicle structure components which influence the european offset impact characteristics were chosen as the main factors fur the design. Eight factors were considered for the analysis: one with two level and seven with three level combinations comprising the L$\_$18/(2$^1$$\times$3$\^$7/) orthogonal array. It is shown that the sensitivities of the factors and the best combination of the factors can be obtained. One of the noteworthy results is that the design with the lower stiffness of the front components of engine room than the rear components can absorb more crash energy. Also it is shown that there exist interactions between some of factors considered.

  • IoT(사물 인터넷)는 더 이상 개념에만 머물러있지 않고, 개인 사용자가 직접 소형 보드와 부품을 통해 구현을 해보는 등 일상화되었다. 본 연구는 일반 장난감 자동차를 라즈베리 파이와 모터 드라이브를 이용하여 제어하는 시스템을 구현하였다. 이 연구를 통해 일반 장난감 자동차를 RC 카로 만들거나 추가적인 개발로 학습을 하고 자율주행을 하는 등의 발전을 시킬수 있을 것이다.

  • In this paper, an optimal power distribution algorithm is proposed for the small electric vehicle with front in-line and rear in-wheel motors. First, it is assumed that the vehicle driving torque and velocity are given conditions. And, an optimal problem is defined that finding the front and rear motor torques which minimizes the battery power. From the above optimization problem, the optimized front-rear motor torque distribution map is obtained. And, the vehicle simulations are performed to verify the performance of the optimal power distribution algorithm which is proposed in this study. The simulations are performed based on the federal urban driving schedule for two cases which are constant ratio power distribution, and optimal power distribution. From the simulation results, it is found that the optimal power distribution shows the 6.3% smaller battery energy consumption than the constant ratio power distribution.

  • European side impact analysis of an electric vehicle was done using robust design. Locations and section properties of some of the vehicle structure components which influence the european side impact characteristics were chosen as the main factors for the robust design. Eight factors were considered for the analysis: one with two level and seven with three level combinations comprising the L18(21$\times$37) orthogonal array. It is shown that the sensitivities of the factors and the best combination of the factors can be obtained, and that the location of the main components were as much sensitive as the section properties of those. Also it is shown that the interactions were existed between some factors.

  • Head-Up Display system makes it possible for the driver to be informed of important vehicle data such as vehicle speed, engine RPM or navigation data without taking the driver's eyes off the road. Long focal length optics, LCD with bright illumination, image generator and vehicle interface controllers are key parts of head-up display system. All these parts have been designed, developed and applied to the test vehicle. Virtual images are located about 2m ahead of the driver's eye by projecting it onto the windshield just below the driver's line of sight. Developed head-up display system shows satisfactory results for future commercialization.

  • The development of more safe recliners is an important issue in the automotive industry. However, the development of new recliners is costly and take much time because it is typically based on experimental evaluation using prototypes. This study presents the evaluation of rear crashworthiness for round recliner using finite element method. That reduces the number of repeating test and gives an information about stiffness. To evaluate rear crashworthiness, the FMVSS 301 simulation and pendulum impact simulation were performed. The load path on two simulations was observed and compared each other in this paper. Also stress, strain and internal energy was compared. It is attempted the tooth strength simulation using a substructure option on PAM-CRASH.

  • Recently, automobile industries have developed ADAS, smart cars, connected cars, automated driving systems, which use a variety of sensor systems - ultrasonics, cameras, lidars and radars - and communication systems. It is necessary to examine the electromagnetic immunity of vehicles equipped with those systems. The electromagnetic immunity tests are carried out in an electromagnetic semi anechoic chamber, which is cut off from the outside. It is difficult to create test environments in which the radar sensor systems of vehicles work properly in the test chamber. In this study, test jigs were designed and tested and as a result they are shown to be effective to create test environments for electromagnetic immunity tests of vehicles equipped with radar sensors. We also proposed additional safety standards for immunity tests of vehicles with radar systems that currently do not exist.

  • Obstacle detection and avoidance are considered as one of the key technologies on an unmanned vehicle system. In this paper, we propose a method of obstacle detection and avoidance and it is composed of vehicle control, modeling, and sensor experiments. Obstacle detection and avoidance consist of two parts: one is longitudinal control system for acceleration and deceleration and the other is lateral control system for steering control. Each system is used for unmanned vehicle control, which notes its location, recognizes obstacles surrounding it, and makes a decision how fast to proceed according to circumstances. During the operation, the control system of the vehicle can detect obstacles and perform obstacle avoidance on the road, which involves vehicle velocity. In this paper, we propose a method for vehicle control, modeling, and obstacle avoidance, which are evaluated through road tests.
