  • In autonomous car, significant progress has been achieved in technical aspects, but it is deadly slow to solve its various legal problems for commercialization of autonomous car. This paper surveys the road driving eligibility, a typical legal issue in autonomous car. Problems on current laws and regulations are analyzed, and some remedies are suggested. Technical development should be performed collaboratively with law and regulation revision, and understanding these legal issues would be very helpful to the engineers who develop autonomous cars.

  • 사물 인터넷, 클라우드 컴퓨팅, 인공지능, 빅데이터 등 첨단 정보통신기술을 활용하여 모든 사물들의 지능화와 초연결을 지향하는 것을 나타내는 4차 산업혁명에 대한 관심은 나날이 증가하고 있다. 4차 산업혁명과 관련된 다양한 분야의 기술들 중에서 인공지능을 활용한 자율주행자동차 기술과 관련하여 논의를 진행하고자 한다. 여러 국가에서는 자율주행자동차 시장선점을 위해 관련 기술의 발달에 몰두하고 있다. 그러나 자율주행자동차의 상용화를 위해서는 기술의 발달뿐만 아니라 관련 법제도의 정비가 더욱 필수적인 요소라고 본다. 자율주행자동차가 안전성을 보장할 수 있도록 시험운행에 대한 규제를 완화시켜야 할 것이며, 향후 상용화가 될 경우 야기될 수 있는 민사적 손해배상문제와 형사책임의 문제, 과실책임의 문제, 사이버 보안문제 등을 대비할 수 있는 법제도 마련을 촉구하고자 한다. 타국가와의 자율주행자동차 법제도 비교분석을 통해 우리나라의 도로교통법과 기존 법 제정상태를 고려하여 법안 마련에 방향성을 설정하는 데에 목표를 두고 있다.

  • 무인 운반차 등의 주행괘적을 검출하기 위해서는, 일반적으로 순간적인 주행속도와 진행방향을 축차적으로 검출하여 이로부터 궤적을 측정하는 방법이 이용되어져 왔으며, 이를 위하여 종래에는 타코미터, 2차 상관법, 공간 필터법 등과 같은 속도 계측 수단과 스티어링 각도 검출기, 자이로등의 회전각 검출 수단을 병용하여야 했다. 본 논문에서는 복수개의 광 선 검출기 군과 이에 대응하는 고차의 상관처리를 이용한 단일계로서 차량의 임의의 궤적을 원호로 근사하여 검출함으로써 곡선 궤적인 경우에도 고정도의 궤적추정이 가능한 새로운 계측법을 제안한다.

  • 자율주행차는 운전자가 직접 조작하지 않아도 자동차가 주변 환경을 인식해 위험을 판단하고 주행경로를 계획하여 운전자 주행조작을 최소화하며, 스스로 안전운행이 가능한 인간 친화형 자동차이다. 각국은 프로젝트 등을 통해 기술개발을 지원하고 법제화로 후원하고 있는데, 사람이 운전하지 않는 자율주행차가 도로 위를 달릴 수 있는지 논란이 되고 있어 '운전자가 제어하는 차'를 기준으로 관련법을 제정하고 있다. 업체들은 공공도로에서 주행할 수 있는 임시허가를 받아 자율주행차를 시험주행하는 등 개발에 박차를 가하고 있다.

  • Although there have been many studies on laws and systems for the proliferation of autonomous vehicles, studies on the activation of autonomous vehicles from a strategic perspective are insufficient. This study examines the issues and problem solving methods of autonomous vehicles. Based on this, plans to activate autonomous vehicles from a strategic point of view are proposed. In order to solve the issues and problems of autonomous vehicles, it is necessary to clearly establish legal and institutional standards based on the reinforcement of the safety of autonomous vehicles. In the event of a traffic accident, who is responsible for the accident and responsibility for compensation should be prioritized. Diffusion strategies are established according to the level of autonomous driving for the activation of autonomous vehicles in strategic perspective. In addition, governmental support policies should be used as triggers for initial activation, and marketing mix strategies should be implemented based on segmentation, targeting, and positioning strategies.

  • We developed a computational method on coupled dynamics of tracked vehicle on seafloor and long flexible pipe. The tracked vehicle is modeled as rigid-body vehicle, and the linked flexible pipe is discretized according to a lumped-parameter model. The equations of motion of the rigid-body vehicle on the soft seafloor are combined with the governing equations of flexible pipe dynamics. Four Euler parameters method is used to express the orientations of the vehicle and the flexible pipe. In order to solve the nonlinear coupled dynamics of vehicle and flexible pipe an incremental-iterative formulation is implemented. For the time-domain integration $Newmark-\beta$ method is adopted. The total Jacobean matrix has been derived based on the incremental-iterative formulation. The interactions between the dynamics of flexible pipe and the mobility of the tracked vehicle on soft seafloor are investigated through numerical simulations in time domain.

  • The fuel-cut coast-down driving mode is activated when the acceleration pedal is released with transmission gear engaged, and it's a default function for electronic-controlled engine of vehicles. The fuel economy becomes better because fuel injection stops during fuel-cut driving mode. A fuel-cut detection method is suggested in the study and it's based on the speed, acceleration and road gradient data from GPS sensor. It detects fuel-cut driving mode by comparing calculated acceleration and realtime acceleration value. The one is estimated with driving resistance in the condition of fuel-cut driving and the other is from GPS sensor. The detection accuracy is about 80% when the method is verified with road driving data. The result is estimated with 9,600 data set of vehicle speed, acceleration, fuel consumption and road gradient from test driving on the road of 12km during 16 minutes, and the road slope is rather high. It's easy to detect fuel-cut without injector signal obtained by connecting wire. The detection error is from the fact that the variation range of speed, acceleration and road gradient data, used for road resistance force, is larger than the value of fuel consumption data.

  • This paper proposes a fuzzy algorithm for determining navigation path of an autonomous mobile robot in uncertain environment. The proposed fuzzy algorithm includes three type (MIN-TIME, ECONOMY, SAFETY) motion modes for the robot to get the ability to meet the ambiguous situation which the robot encounters. Ech ode is applied to both static and dynamic environmental situation. This paper concludes by showing the efficiency of the proposed method through some computer simulation results.

  • Commercialization of level-4 (Lv.4) autonomous driving applications requires the definition of a safe road environment under which autonomous vehicles can operate safely. Thus, a risk assessment model is required to determine whether the operation of autonomous vehicles can provide safety to is sufficiently prepared for future real-life traffic problems. Although the risk factors of autonomous vehicles were selected and graded, the decision-making method was applied as qualitative data using a survey of experts in the field of autonomous driving due to the cause of the accident and difficulty in obtaining autonomous driving data. The fuzzy linguistic representation of decision-makers and the fuzzy analytic hierarchy process (AHP), which converts uncertainty into quantitative figures, were implemented to compensate for the AHP shortcomings of the multi-standard decision-making technique. Through the process of deriving the weights of the upper and lower attributes, the road alignment, which is a physical infrastructure, was analyzed as the most important risk factor in the operation risk of autonomous vehicles. In addition, the operation risk of autonomous vehicles was derived through the example of the risk of operating autonomous vehicles for the 5 areas to be evaluated.
