Optimizing Hybrid Electric Powertrains for Connected and Automated Vehicles (CAV)

加拿大通用汽车公司（GM）和滑铁卢大学（UW）将研究汽车设计中与联网和自动驾驶汽车（CAV）相关的两个重要方面：(i)联网和自动驾驶汽车对现实世界驾驶习惯的影响，进而影响动力总成设计；（ii）调查CAV对混合动力电动汽车能源管理策略的影响，包括对排放和燃料/能源消耗的影响。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量产车改造成一辆集成了自动驾驶汽车和动力系统功能的混合动力汽车。这将作为一个完全可定制的车辆测试平台，为学生提供独特的动手学习和接触工业级工具和流程。学生亦将有机会亲身参与新一代智能交通系统及车辆自动化的发展。第一个研究课题涉及自动驾驶汽车对驱动循环和动力系统选择的影响。传统上，原始设备制造商使用政府提供的驱动循环来设计他们的车辆。通过与通用汽车的合作，CAV将对现实生活中的驾驶习惯产生的影响将被捕捉和检验。通过了解能够影响车辆设计的CAV因素，通用汽车将能够更好地设计车辆以满足消费者的需求。第二个研究课题将帮助通用汽车了解CAV如何对混合动力汽车的排放和燃料消耗产生影响。一个感兴趣的领域将是研究车辆全局映射，定位，预测和路径规划系统的发展将如何影响动力总成能源管理，以最大限度地减少能源消耗。此外，本研究将测量将已开发系统的软件和硬件从实验室环境迁移到消费者就绪车辆所需的资源。有了这些信息，通用汽车将能够量化将这些概念转移到公路车辆上的成本。加拿大人受益的是减少排放和燃料消耗的车辆，这些车辆不仅适合我们独特的景观和驾驶模式，而且适合未来的智能交通基础设施。

General Motors of Canada Company (GM) and University of Waterloo (UW) will research two important aspects of vehicle design with respect to connected and automated vehicles (CAV): (i) the effects of connected and automated vehicles on real-world driving habits that in turn influences powertrain design, and (ii) investigation of CAV's impact on hybrid electric vehicle energy management strategies in regards to effects on the emissions and fuel/energy consumption. To support these research topics, UW will convert an existing, production GM vehicle into a hybrid electric vehicle with integrated CAV and powertrain functionalities. This will act as a fully customizable vehicle test bed providing students with unique hands-on-learning and exposure to industry grade tools and processes. Students will also have a unique opportunity to be involved in the race to develop the next generation of intelligent transportation systems and vehicle automation. The first research topic relates to the influence CAV can have on drive cycles and the powertrain selection. Traditionally OEMs use government provided drive cycles to design their vehicles. By collaborating with GM, the effects that CAV will have on real-world driving habits will be captured and examined. By understanding the CAV factors that can influence vehicle design, GM will be able to better design their vehicle's to meet consumer needs. The second research topic will aid GM in understanding how CAV can have an impact on hybrid vehicle emissions and fuel consumption. An area of interest will be the study of how the development of vehicle global mapping, localization, prediction and path planning system will influence powertrain energy management to minimize energy consumption. Additionally, this research will measure the resources needed to migrate the software and hardware of the developed system from a laboratory setting to a consumer ready vehicle. With this information, GM will be able to quantify the costs of migrating the concepts to on-road vehicles. The benefit to Canadians are vehicles designed to reduce emissions and fuel consumption, which are not only tailored to our unique landscape and driving patterns, but also to the intelligent transportation infrastructure of the future.
