讲座题目：In Search Of Novel Power -Split Hybrid Electric Vehicles 讲座时间：2016年9月2日15:00 讲座地点：重庆大学A区主教学楼515会议室 主 讲 人：Dongsuk Kum韩国科学技术院 主办单位：重庆自主品牌汽车协同创新中心（http://qczx.cqu.edu.cn/） 欢迎各单位老师、同学参加，并针对有关问题现场提问。 讲座内容： Fuel economy of hybrid electric vehicles has been steadily improving over the last couple of decades, and it seems to be reaching its limits.In fact, any OEMs can reduce HEVs that can achieve fuel economy close to the limit regardless of powertrain topologies if constraints on cost (e.g. motor size) and/or acceleration performance are relaxed. Therefore, both drivability and cost must be considered when searching for novel HEV architecture. Among others, power-split hybrids are known for their high potentials because split hybrids provide a large number ofdifferentconfigurations; twenty four ways of connecting four components (two electric machines,an engine,anda vehiclewheel)with a planetary gear (PG),and more than thousand ways with two PGs. Despite high potentials, finding the best split hybrid was practically impossible due to the large design space. For instance, each compound -split hybrid configurationhasthreedesignvariables;PG1,PG2,andfinaldrivegearratios.Recently, the research team at Korea Advanced Institute of Science & Technology (KAIST) evaluated both fuel economy and acceleration performance for all compound -split hybrid configurations and found a few novel compound-split HEV powertrain architecture. Simulation results confirm that the new architecture outperformsall thehybridson themarketfrombothfuel economyandaccelerationperformance perspectives. The focus of this talk will be on how KAIST team was able to find the novel compound-split hybrid architecture, namely the comprehensive design methodology.
主讲人简介： Dongsuk Kum received his Ph. D. degree in mechanical engineering from the University of Michigan, Ann Arbor, in 2010. He is currently an Assistant Professor at the Graduate School for Green Transportation in Korea Advanced Institute of Science & Technology (KAIST), and the Director of the Vehicle Dynamics and Controls (VDC) Laboratory. His research centers on the modeling, control, and design of advanced vehicular systems with particular interests in hybrid electric vehicles and autonomous vehicles. Prior to joining KAIST, Professor Kum had worked for the General Motors R&D Propulsion Systems Research Laboratory in Warren, MI as a visiting research scientist. His works at General Motors focused on advanced propulsion system technologies including hybrid electric vehicles, flywheel hybrid, and waste heat recovery systems. |
