하이브리드 자동차의 주행 모드 변환에 따른 실시간 모니터링 교육용 콘텐츠 개발
이중순(Lee, Joong-Soon),손일문(Son, Il-Moon) 한국산학기술학회 2011 한국산학기술학회논문지 Vol.12 No.4
Toyota사의 PRIUS THS 시스템을 이용하여 HEV 알고리즘 분석을 통한 THS의 주행 모드 변환에 따른 실시 간 모니터링 시스템을 개발하고자 한다. 병렬형 하이브리드 시스템의 경우에 엔진과 전동기를 주행 상태 최적인 상태 로 운행하기 위해서는 다양한 제어전략이 필요하다. 본 연구를 통하여 주행 가능한 THS 차량의 주행에 필요한 입․출 력 정보를 실시간적으로 모니터링할 수 있는 시스템을 개발한 결과, 하이브리드 자동차의 동력 분할 및 에너지 활용 을 극대화시키기 위한 수단의 하나로 차량의 주행모드 변화에 따른 각 구성요소의 동작 상태를 모니터링 가능하게 되었다. 개발된 시스템은 제어전략의 체계적인 수립과 실시간 데이터 분석이 가능하기 때문에 HEV자동차의 알고리즘 분석해석을 통해 HEV자동차의 개발 기반에 유용하게 활용될 것이다. A key factor in the study of hybrid vehicle is to enhance the usability of energy. The paper introduces the monitor and controlling technology of hybrid vehicle that can process the relevant information considering the structure of power system and driving strategies simultaneously, and can monitor its results. This technology, so called HEV algorithm analysis, has been applied to PRIUS THS made by Toyota Co. LTD. This model is adapted to parallel hybrid type. It has a somewhat comlex structure, but has several merits. It's energy loss is lower when conversing. and also it is easily applied to the conventional vehicle having a gasoline engine without any overall changing of its structure, and so on. This monitor and controlling technology is very useful to study on the various driving strategies of hybrid vehicle for maximizing the usability between engine and electric motor.

The hybridization of the conventional thermal vehicles nowadays constitutes a paramount importance for car manufacturers, facing the challenge of minimizing the consumption of the road transport. Although hybrid power train technologies did not converge towards a single solution, series/parallel power trains with power-split electromechanical transmissions prove to be the most promising hybrid technology. In fact, these power trains show maximum power train overall efficiency and maximum fuel reduction in almost all driving conditions compared to the conventional and other hybrid power trains. This paper addresses the model and design of the electro-mechanical configuration of one of the most effective HEV power trains: case study of the 2nd generation Prius. It presents the simulation work of the overall operation of the Toyota Hybrid System (THS-II) of the Prius, and explores not only its power-split eCVT innovative transmission system but also its overall supervision controller for energy management. The kinematic and dynamic behaviors of the THS-II power train are explained based on the power-split aspect of its transmission through a planetary gear train. Then, the possible regular driving functionalities that result from its eCVT operation and the energy flow within its power train are outlined. A feedforward dynamic model of the studied power train is next proposed, supervised by a rule-based engineering intuition controller. The energy consumption of the THS-II proposed model has been validated by comparing simulation results to published results on European, American and Japanese regulatory driving cycles.

In this paper, a new drive system(SHS) for hybrid electric vehicle is proposed. As dual rotor hybrid electric vehicle using planetary gearsets, the SHS has the advantages of both series and parallel systems. The output speed and torque of SHS can be determined at specific point regardless of the engine`s operating point. When the size of generator which is used in SHS is same as in THS, the SHS has more activities of engine control due to the ability that is operated in lower speed range. To maximize the performance of system, we carried out optimization for the three parameters that are engine, motor1 and motor2. As the result of the optimization, we confirmed the SHS is more preferable to THS in fuel consumption and acceleration area.

PMP를 이용한 Plug-in 하이브리드 차량의 주행 최적화 전략
변상민(Sangmin Byun),김남욱(Namwook Kim),박영일(Young-il Park),차석원(Suk-Won Cha) 한국자동차공학회 2009 한국자동차공학회 부문종합 학술대회 Vol.2009 No.4
A control concept based on PMP(Pontragyn's Minimum Principle), which produces necessary conditions for an optimal control, can be adapted to optimal cruise control for PHEV(Plug-in hybrid electric vehicle), and the concept has many advantages comparing to DP(Dynamic programming). In HEV optimal problems, the DP requires a great of database to find out an optimal trajectory, whereas the PMP can save calculating time and efforts to obtain the optimal trajectory. In this study, three PHEV control strategies, a charge depleting-sustaining strategy, a PMP optimal control strategy, and a charge sustaining-depleting strategy, are analyzed by both DP method and PMP method. Especially, in the PHEV system, we can find out a global optimal control solution when we set an appropriate value of costate in PMP. This paper also demonstrates results solved from PMP are closely related to optimal control results from DP..
