Center for Low Emission Vehicle Research (CLEVeR)

低排放车辆研究中心（CLEVeR）是对现有设施进行的最先进的设备升级，以允许在真实的世界驾驶条件下研究低碳和超低碳液体燃料车辆以及新型电动和混合动力电动车辆（EV/HEV）平台。虽然传统燃料内燃机驱动的车辆仍将是未来的主要动力系统，但替代燃料车辆（AFV）以及向更多电动和混合动力车辆的转变将获得动力。欧盟新的汽车二氧化碳法规规定，到2020年，欧盟的每个制造商必须平均95克/公里的二氧化碳。2012年英国新车数据平均为133.1 g/km，实现2020年目标将具有挑战性。对现有车辆设施进行升级的需求受到大型研究挑战的推动，该挑战支持提供可持续个人交通工具的需求，以减少或消除二氧化碳进入我们的环境。在帮助创造更清洁的环境和减缓气候变化方面，车辆设施内将开展的工作将直接解决我们这个时代最迫切的问题之一。该设施将是英国独一无二的，将创建一个最先进的设施，允许研究新的二氧化碳减排技术，可以以高度的实验精度进行评估。对技术本身进行了大量研究，但在复制真实的世界条件的环境中进行的系统一级的研究很少，这类设施在工业中可以找到，主要用于产品开发，支持车辆方案，一般不用于研究。这是巴斯设施与其他设施的主要区别。该设施将是多用户的，我们的目标是提供一个包容性和可访问的研究能力，目前禁止或不存在的许多学术，甚至工业研究团队，特别是中小企业。一些重要的研究领域，该设施已被设计，以解决如下所述：-目前的EV/HEV系统是阻碍了缺乏系统优化，特别是在真实的世界的驾驶条件。该设施将提供一个环境，世界领先的研究可以解决能源效率和存储，组件和子系统的集成热管理，特别是在极端温度和湿度条件下的车载问题。分布式电动机系统的趋势需要如所提出的四轮系统。设计用于评估电机，控制器和电池动态性能的其他测量仪器也包括在内，以评估电气系统上的高频信号。未来发动机开发和燃料研究的一个关键挑战是将燃料的物理和化学性质与燃烧特性、排放形成和排放控制系统联系起来。该设施将使燃料科学家和车辆工程师能够共同努力，在早期阶段更好地了解新燃料对排放，二氧化碳生产，车辆和发动机性能的影响。驾驶员是车辆系统中最不可预测的因素，为了评估未来低碳CO2推进系统和子系统在真实的世界运行中的有效性，更好地了解驾驶员行为至关重要。未来车辆技术的性能通常在法定行驶循环（如新欧洲行驶循环（NEDC））上进行评估。虽然通常指示趋势，但是该方法不能提供关于这些系统在关于驾驶员需求和周围环境条件的真实的世界驾驶条件下的操作的准确、鲁棒的信息。该设施将使调查的环境之间的相互作用，其中车辆正在使用和驾驶的方式。

The Centre for Low Emission Vehicle Research (CLEVeR) is a state-of-the-art equipment upgrade to an existing facility to allow research into low and ultra-low carbon liquid fueled vehicles as well as novel electric and hybrid electric vehicle (EV/HEV) platforms under real world driving conditions. Although conventionally fueled internal combustion engine powered vehicles will remain the dominant powertrain for the future, alternatively-fuelled vehicles (AFVs) and the shift to more electric and hybrids vehicles will gather momentum. The EU New Car CO2 Regulation mandates that by 2020 each manufacturer in the EU must average 95g/km of CO2. The UK new car figures for 2012 returned a 133.1 g/km average and achieving the 2020 target will be challenging.The requirement to upgrade the current vehicle facility has been driven by the large research challenge that underpins the need to provide sustainable personal transport that reduces or eliminates CO2 into our environment. In helping to make a cleaner environment and mitigate climate change, aspects of the work to be undertaken within the vehicle facility will directly address one of the most imperative issues of our time.The facility will be unique in the UK, a state-of-the-art facility will be created allowing research into new CO2 reducing technologies which can be assessed with a high degree of experimental precision. Much research is carried out on the technologies themselves, but very little is done at a systems level in an environment that replicates real world conditions.Facilities such as this are found in industry and are mainly used for product development, supporting vehicle programmes and are not generally used for research. That is the major difference between the Bath facility and others. The facility will be multi-user and we aim to provide an inclusive and accessible research capability currently prohibitive or non-existent to many academic and even industrial research teams and especially SMEs.Some important research areas that the facility has been designed to address are described below:-Current EV/HEV systems are hampered by a lack of system optimisation, particularly under real world driving conditions. The facility will deliver an environment where world leading research can address the on-vehicle issues of energy efficiency and storage, integrated thermal management of components and subsystems especially under extreme temperature and humidity conditions. The trend to distributed motor systems requires a four wheel system such as that proposed. Further measurement instruments designed to evaluate the dynamic performance of the motor, controller and battery are included to evaluate the high frequency signals on the electrical systems.-A key challenge of future engine developments and fuel research is linking the physical and chemical properties of the fuel with the combustion characteristics, emissions formation and emissions control systems. This facility will enable fuel scientists and vehicle engineers to work together to be more aware and better informed of the effects of new fuels, at an early stage, on emissions, CO2 production, vehicle and engine performance.-The driver is the least predictable element within the vehicle system and better insights into driver behaviour are essential in order to evaluate the effectiveness of future low carbon CO2 propulsion and sub-systems under real world operation.-The performance of future vehicle technologies are usually evaluated over legislative drive cycles such as the New European Drive Cycle (NEDC). While often indicative of trends, this method fails to provide accurate, robust information on the operation of these systems under real world driving conditions with respect to driver demands and ambient environmental conditions. This facility will enable investigations in to the interactions between the environment in which a vehicle is being used and the manner in which it is driven.
