中大通讯 CUHK Newsletter 6 香 港空气污染问题严重,汽车废气是 主要污染物之一。本校机械与自动 化工程学系徐扬生教授成功开发了全球首 辆四轮转向的智能环保混合动力汽车,预 计可于两年后正式投产,该汽车可大大减 低废气排放和节省能源,并且适合在挤迫 的道路行驶。 徐教授表示,为了尽量减少汽车排放废 气,全电动环保汽车乃世界大趋势,但在 充电站及全电动车未普及前,混合动力车 将逐渐成为主流车种。中大开发的混合动 力车使用了串联混合动力技术,预计可提 高燃油效率达三至四成,减少五至六成的 污染排放量。中大的研究在电机控制上作 出多方面创新,智能化汽车采用了线控技 术,以电子代替机械来控制起动和刹车等 指令,使汽车可做到四轮转向(4WS), 有利于车多路窄的城市环境,令汽车在停 泊方面更灵活和节省空间。四轮驱动技术 (4WD)亦增强汽车的动力和爬坡性能, 缩短起步加速的时间。 有关研究项目获得创新及科技基金资助, 是香港与内地政府、企业和大学积极合作的成果。汽车 零部件为政府积极推动的五个重点科研范畴之一,参与 合作开发项目公司的华普汽车计划于两年后正式开始生 产这辆环保混合动力智能汽车。早前香港特区行政长官 曾荫权先生亦亲临中大「智能混合动力汽车研究中心」 ,了解该辆由徐教授开发的混合动力车。 H ong Kong’s air pollution deteriorates as automobiles continue to emit exhaust — one of the main pollutants of the city. On 3rd November, the University announced the development of an Intelligent Omni- directional Hybrid Electric Vehicle, an environment-friendly car of the next generat- ion that will help to clean up our sky. 中大开发全球首辆四轮转向的智能环保混合动力车 CUHK Develops Environmentally Friendly Automobiles 以下项目详情,请上网 http://www.cuhk.edu.hk/iso/ newslter/issue/287/discoveries.htm 阅览: ■ 中大研究亚洲家族企业如何成功延续至下一代 CUHK Examines How Asian Family Businesses Can Continue Their Success Across Generations ■ 中大临床试验在获国家食品药品监督管理局认证后的 发展 CUHK Clinical Drug Trails Development for China SFDA ■ Three Research Projects Received Grants (左起) 特首曾荫权先生、刘遵义校长、机械与自动化工程学系徐扬生教授及该系系主任 任扬教授 From left: Mr. Donald Tsang, Chief Executive, Prof. Lawrence J. Lau, Prof. Xu Yangsheng, and Prof. Yam Yeung 徐扬生教授一九九七年一月加入中文大学,现为自动化与计算机辅助工程学讲座教授。他曾任教卡内基梅隆大 学计算机学院,并创建了首间无重力太空机器人实验室和地面实时控制中心。 徐教授在智能控制理论上作出过许多贡献,例如,他所领导研发的对车辆驾驶技能的实时检模的系统,已成功 用于世上第一辆横跨美洲大陆的无人自动车。他又设计了能在太空站上行走操作的自助式机器人,是国际太空 站上工作的机器人原模。 Prof. Xu Yangsheng, professor of Automation and Computer-Aided Engineering, joined The Chinese University of Hong Kong in 1997. He was a faculty member at the Robotics Institute, School of Computer Science, Carnegie Mellon University where he directed the Space Robotics Laboratory and developed the world first zero-gravity laboratory environment and various real-time controlled space robots systems. Prof. Xu has made contributions to the modelling and transfer of human control strategy to autonomous systems, and his systems were implemented in the world’s first autonomous land vehicle to drive across the American Continent. He developed robot prototypes that can walk or climb and perform tasks at space stations. They have been used as a model for the robots working in today’s international space stations. the project, the use of environment- friendly vehicles like electrical cars is a worldwide trend. But before electric vehicles and their charging stations become widely and conveniently available, the Hybrid Electric Vehicle will be the mainstream. To achieve both performance and environmental friendliness, the vehicle employs three major innovative technologies. The first is the Series Hybrid Technology, which is expected to reduce fuel consumption by 30–40% and emission by 50–60%. The four- wheel-steering (4WS) technology enables flexible movement of the vehicle even on the narrow and busy streets of Hong Kong, making parking a lot easier and reducing the need for parking space. The last technology is the four-independent-wheel-drive technology (4WD). It strengthens the vehicle’s climbing performance and reduces start-up acceleration time. In addition to the support of the Innovation and Technology Fund (ITF), the project was made possible by the active cooperation of all units including CUHK, government, industry and research units in Hong Kong and the Mainland. Automotive parts and accessory systems is one of the five key areas of strategic research area supported by the SAR government. One of the industrial partners sponsoring the project, Shanghai Maple Automobile Co. Ltd., plans to produce the Hybrid Electric Vehicle in about two years’ time.
