Vehicles’ powertrain electrification is one of the key measures adopted by manufacturers in order to develop low emissions vehicles and reduce the CO2 emissions from passenger cars. High complexity of electrified powertrains increases the demand of cost-effective tools that can be used during the design of such powertrain architectures. Objective of the study is the proposal of a series of real-world velocity profiles that can be used during virtual design. To that aim, using three state of the art plug-in hybrid vehicles, a combined experimental, and simulation approach is followed to derive generic real-world cycles that can be used for the evaluation of the overall energy efficiency of electrified powertrains. The vehicles were tested under standard real driving emissions routes, real-world routes with reversed order (compared to a standard real driving emissions route) of urban, rural, motorway, and routes with high slope variation. To enhance the experimental activities, additional virtual mission profiles simulated using vehicle simulation models. Outcome of the study consists of specific driving cycles, designed based on standard real-world route, and a methodology for real-world data analysis and evaluation, along with the results from the assessment of the impact of different operational parameters on the total electrified powertrain.

针对电动动力系统车辆校准的真实世界驾驶循环的评估和设计
汽车动力总成电气化是制造商为发展低排放汽车和减少CO 2而采取的关键措施之一乘用车的排放。电气化动力系统的高度复杂性增加了对可在此类动力系统架构设计过程中使用的具有成本效益的工具的需求。该研究的目的是提出一系列可在虚拟设计中使用的真实世界速度剖面。为此,我们使用三种最先进的插电式混合动力汽车,结合实验和模拟方法来推导出可用于评估电气化动力系统整体能源效率的通用真实世界循环。车辆在标准的实际驾驶排放路线、城市、农村、高速公路的倒序(与标准的实际驾驶排放路线相比)的实际路线以及坡度变化较大的路线下进行了测试。为加强实验活动,使用车辆仿真模型模拟的其他虚拟任务配置文件。研究结果包括基于标准真实世界路线设计的特定驾驶循环、真实世界数据分析和评估方法,以及不同运行参数对整个电动动力总成影响的评估结果.
