This paper describes a Forward Collision Warning (FCW) system based on the radar driven fusion with camera. The objective of FCW system is to provide an appropriate alert with satisfying the evaluation scenarios of US-NCAP and a driver acceptance. For this purpose, this paper proposed a data fusion algorithm and a collision warning algorithm. The data fusion algorithm generates information of fusion target depending on the confidence of camera sensor. The collision warning algorithm calculates indexes and determines an appropriate alert-timing by using analysis results of manual driving data. The FCW system with the proposed data fusion and collision warning algorithm was investigated via scenarios of US-NCAP and a real-road driving. It is shown that the proposed FCW system can improve the accuracy of an alarm-timing and reduce the false alarm in real roads.

본 연구는 바이오 벤처기업의 경영 성과에 내부역량과 외부 요인들이 어떤 영향을 미치는 지를 파악하기 위해 내부역량으로 최고경영진역량과 기술력, 외부요인으로 기업 네트워크, 벤처캐피탈 투자, 정부연구개발비 지원이 미치는 영향을 구조방정식을 이용해 실증적으로 분석하였고, 기업 네트워크, 벤처캐피탈 투자, 정부연구개발비지원의 매개효과를 검증하였다. 분석 결과, 첫째, 바이오벤처기업의 경영성과에는 최고경영진의 기능다양성과 핵심 업무지식, 기업 네트워크가 긍정적인 영향을 끼쳤다. 특히, 핵심 업무지식이 경영 성과에 미치는 영향이 큰 것으로 나타났다. 둘째, 바이오벤처기업의 경영 성과에는 기술력, 벤처케피탈투자, 정부연구개발비 지원은 의미있는 영향을 끼치지 않는 것으로 나타났다. 이는 바이오벤처기업의 경영 성과에 벤처캐피탈의 투자나 정부연구개발비 지원보다 대기업, 전문의료기업 등 관련 기업의 지원 등이 더 큰 영향을 미칠 수 있기 때문으로 판단된다. 셋째, 기술력은 단독으로 경영 성과에 의미있는 영향을 끼치지는 못했지만, 기업 네트워크의 매개효과를 통해 성과에 영향을 줄 수 있는 것으로 나타났다. 이는 기술력이 바이오기업의 성과에 긍정적인 영향을 주기 위해서는 기업 네트워크의 확대가 필요하다는 것을 의미한다. TMT의 핵심 업무지식과 성장단계별로 부족한 자원을 조달할 수 있는 기업 네트워크가 바이오벤처기업의 성장에 필수적인 요인으로 작용하며, 기업 네트워크를 활용할 때 기업성장은 더 빨라질 것이다. 바이오벤처기업의 경영 성과에 직접적인 영향을 미치지 못하는 것으로 나타난 벤처캐피탈 투자와 정부연구개발비에 대해서는 추가적인 연구가 필요하다. The purpose of this study is to analyze the effect of some factors on the business performance of bio-venture companies. Empirical analysis was conducted for Top management Team capabilities, Technology as internal competence and Corporate Networks, Venture-Capital Investment, Government R&D Support as external factors. In addition, this study verified the mediation effects of corporate networks, venture-capital investment, and government R&D support as intermediate pathways. The empirical results are as follows: First, diversification, core job experience and corporate networks of Top management Team are positive impact factors in the business performance of bio-venture companies. In particular, core job experience was the most influential factor. Second, technology, venture-capital investment and government R&D support are positive impact factors for performance. It is because the bio-venture companies do not efficiently utilize the technology and investment funds. Third, venture-capital investment and government R&D support give mediating effect to the technology for the performance. Leveraging external partners having funding and research skills can give a positive impact on the business performance of bio-venture company.

This paper presents methods of robot localization using recent Radio Frequency Identification technology. If the absolute location and orientation of a passive tag are given in indoor environment which is installed RFID tags, a robot can estimate its location using the relationship of identified tag and robot in relative coordinate. To derive this relationship, we proposes estimation techniques using the probabilistic model of RFID reader, the direction and the maximum range of identification. And condition-processor is combined in a suitable technique depending on the situation and the trajectory of robot in the field of range. Experimental results show that the proposed methods can provide good performance and thus be used for localization.

This paper proposes an analytical redundancy technique for fault diagnostics of the sensor in steer-by-wire system. We use incorporating vehicle dynamics modeling into the design of a diagnostic system for steer-by-wire system. The use of a model of vehicle dynamics improves the speed and accuracy of the diagnoses. The proposed fault diagnostics algorithm is based on parity-space methods to generate residuals. To reduce the effects of modeling uncertainty and dynamic transients, the residuals are subject to filtering. We construct diagnostic system consisting residual threshold for detection and isolator with using the directional residual vector.

This paper presents a longitudinal control strategy for an Adaptive Cruise Control (ACC) with Collision Avoidance (CA) in multiple transitions by a driver and traffic conditions. The objective is for smooth and safe transition between various driving situations to achieve driver’s comfort and prevention of collision. The proposed control strategy consists of a multi-target tracking filter, a primary target selection algorithm and a longitudinal ACC/CA controller. The multi-target tracking filter is used to smooth the sensor signal, and makes it possible to apply to a control system. The primary target selection algorithm decides an important target which has an effect on the subject vehicle. In addition, it provides the information to a longitudinal ACC/CA controller in order to drive a subject vehicle smoothly and improve safety in various traffic transitions. Finally, the longitudinal ACC/CA controller computes the desired acceleration. The performance and safety benefits of the multi-vehicle ACC/CA system is investigated via simulations using real data on driving. Simulation results show that the response of multi-vehicle ACC/CA system is more smooth and safer in multiple transitions.

This paper describes design and tuning of a full-range Adaptive Cruise Control (ACC) with collision avoidance. The control scheme is designed to control the vehicle so that it would feel natural to the human driver and passengers during normal safe driving situations and to avoid rear-end collision in vehicle following situations. In this study, driving situations are determined using a non-dimensional warning index and time-to-collision (TTC). A confusion matrix method based on natural driving data sets was used to tune control parameters in the proposed ACC System. An ECU-Brake Hardware-in-the-loop Simulation (HiLS) was developed and used for an evaluation of ACC System. The ECU-Brake HiLS results for alternative driving situation are compared to manual driving data measured on actual traffic way. The ACC/CA control logic implemented in an ECU was tested using the ECU-Brake HiLS in a real vehicle environment.

This paper presents method of depriving the relationship between static passive RFID tag and mobile robot in the field of tag-range. We use probabilistic sensor model of RFID reader by experiments.
