Bridging the gap between laboratory ready and consumer ready next generation plug-in hybrid electric powertrains

加拿大通用汽车有限公司(GM)和滑铁卢大学(UW)将研究车辆设计的两个重要方面：(I)现实世界驾驶习惯对动力总成设计的影响，以及(Ii)调查基于实验室的设计与消费者准备好的车辆执行之间的差异。为了支持这些研究课题，UW将把现有的、生产的通用汽车改装成插电式混合动力汽车，这将作为一个完全可定制的车辆试验台。该项目还将为学生提供独特的实践学习，并使学生接触到工业级工具和流程。第一个主题涉及驾驶周期对车辆设计的影响。传统上，原始设备制造商使用政府提供的驾驶周期来设计他们的汽车；通过与通用汽车和CrossChasm合作，将捕获和检查现实世界的驾驶习惯。将评估真实世界驾驶习惯和天气对车辆动力总成设计和燃油消耗的影响。通过了解可能影响汽车设计的现实因素，通用汽车将能够更好地设计他们的汽车，以满足消费者的需求。加拿大人将受益于拥有消耗更少燃料的车辆，这些车辆是为我们独特的风景和气候量身定做的。第二个研究课题将帮助通用汽车更好地了解从实验室环境转向消费者就绪质量所需的车辆设计过程和资源。一个有趣的领域是电池热模型，该模型将在实验室条件下开发，并与道路上的实际热性能进行比较。其他令人感兴趣的领域包括研究型汽车与精致消费型汽车的驾驶性能(汽车运行的平稳性)。另一项研究将衡量将车辆控制代码从实验室迁移到车辆所需的资源。有了这些信息，通用汽车将能够量化将概念从实验室迁移到公路车辆的成本。加拿大人的好处是车辆的设计旨在提供更低的成本，减少排放和更好的性能，这要归功于为所有气候设计的更精确的电池、发动机和电机模型。

General Motors of Canada Limited (GM) and University of Waterloo (UW) will investigate two important aspects of vehicle design: (i) the effect of real-world driving habits on powertrain design, and (ii) investigation of the differences between the laboratories based design to consumer ready vehicle execution. To support these research topics, UW will convert an existing, production GM vehicle into a plug-in hybrid electric vehicle, which will act as a fully customizable vehicle test bed. This project will also give students unique hands-on-learning and expose students to industry grade tools and processes. The first topic relates to the influence of drive cycles on vehicle design. Traditionally OEMs use government provided drive cycles to design their vehicles; by collaborating with GM and CrossChasm, real-world driving habits will be captured and examined. The impact of real-world driving habits and weather on vehicle's powertrain design and fuel consumption will be evaluated. By understanding the real-world factors which can influence vehicle design, GM will be able to better design their vehicle's to meet consumer needs. Canadians will benefit by having vehicles which consume less fuel and which are tailored to our unique landscape and climate. The second research topic will aid GM in better understanding the vehicle design process and resources required to move from a laboratory setting to a consumer ready quality. An area of interest is the battery thermal model, will be developed under laboratory conditions and be compared to the actual thermal performance on road. Other areas of interest include the drivability (how smoothly the car operates) of a research vehicle compared to a refined consumer vehicle. An additional study will measure the resources needed to migrate vehicle control code from the laboratory to a vehicle. With this information GM will be able to quantify the costs of migrating concepts from the laboratory to on-road vehicles. The benefit to Canadians are vehicles designed to provide reduced costs, reduced emissions, and better performance, thanks to more accurate battery, engine, and motor models designed for all climates.
