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）将研究汽车设计的两个重要方面：(i)现实驾驶习惯对动力总成设计的影响；（ii）研究基于实验室的设计与消费者就绪的车辆执行之间的差异。为了支持这些研究课题，华盛顿大学将把一辆现有的通用汽车生产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汽车试验台。该项目还将为学生提供独特的动手学习机会，并让学生接触到工业级的工具和流程。第一个主题涉及驱动循环对车辆设计的影响。传统上，原始设备制造商使用政府提供的驱动周期来设计他们的车辆；通过与通用汽车和CrossChasm的合作，可以捕捉和检查真实世界的驾驶习惯。实际驾驶习惯和天气对车辆动力系统设计和燃料消耗的影响将被评估。通过了解影响汽车设计的现实因素，通用汽车将能够更好地设计汽车以满足消费者的需求。加拿大人将受益于拥有油耗更少、适合我们独特景观和气候的车辆。第二个研究课题将帮助通用汽车更好地了解汽车设计过程，以及从实验室环境到面向消费者的质量所需的资源。一个感兴趣的领域是电池热模型，将在实验室条件下开发，并与实际的道路热性能进行比较。其他感兴趣的领域包括研究车辆与精制消费车辆相比的驾驶性能（汽车运行的平稳程度）。另一项研究将测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转移到道路车辆的成本。对加拿大人来说，好处是车辆设计可以降低成本，减少排放，更好的性能，这要归功于更精确的电池，发动机和针对所有气候设计的电机模型。

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.
