| - Development of the Supervisory Control Algorithm for the New Power Propulsion System of a Commercial Vehicle (2008.12.01 ~ 2013.09.30) |
|
|
|
The aim of this project is to develop the supervisory control algorithm which determines energy distribution between each subsystem of the commercial HEV. The validation process of the control algorithm consists of two phases: offline simulation using the vehicle model optimized to analyze the fuel economy, and actual vehicle test using a RCP device to implement the control algorithm. An optimization method is applied to obtain the optimal power split control algorithm, and the fault management algorithm is also developed. |

|
|
Hybridization of bus as public transportation is essential to improve the air pollution. Performance Optimization and Integrated Control Technology development of HEV/PHEV bus is validated by HIL (Hardware In-the Loop) Simulator. HIL Simulator construction consists of vehicle modeling, controller design of sub-system, development of HCU using RCP (Rapid Control Prototype). |

| - Performance Analysis and Control Algorithm Development of the High Mobility Hybrid Propulsion System (2009.06.24 ~ 2011.06.23) |
|
| The military truck requires the performances of high mobility and good fuel efficient to win future battles. Since the hybrid propulsion system brings the both benefits, more and more conventional military vehicles are transformed to the hybrid military vehicles. The aim of this project is to determine the system specification and to develop the supervisory control and fault diagnosis algorithm of series hybrid military truck. The developed control algorithm and fail-safe algorithm in Simulink will be validated by the off-line simulation and HIL simulation. |

|
| Electric Railway system is eco-friendly public transportation because of its efficient running energy. Especially hybrid low-flat trams are urban-friendly transit system. Resently hybrid (catenary+on-board battery) trams are developed by advanced country such as germany, france, japan. The aim of this project is to develope a TPS (Train Performance Simulation) program for hybrid low-flat trams and to optimize its running profile. |

| - Design and Analysis of the Power Propulsion System of a Hybrid Wheel Loader (2010.04.01 ~ 2011.03.31) |
|
|
The wheel-loader system has similar powertrain with conventional transport vehicle whereas the driving pattern is relatively different and patterned. Since optimal structure of hybrid powertrain strongly belongs to its driving pattern, the fuel economy for various types of hybrid wheel-loader is analyzed based on the off-line simulation with the basic supervisory control algorithm to operate the hybrid wheel-loader model. |

|
|
The aim of this project is fault detection and diagnosis algorithm development for the In-Wheel System. The In-Wheel motor has some reliabiliy problems because the motor is mounted in the wheels. The main part of this project is a anaysis of the In-Wheel system fault and development of fault management system. |
