互联网分布式混合动力汽车实车在环仿真平台

Internet-distributed Vehicle-in-the-loop Simulation Platform for Hybrid Electric Vehicles

在原有混合动力汽车(HEV)硬件在环(HIL)仿真的基础上,使用互联网和车联网(IOV)并以数据耦合的形式,将作为中央控制节点的云端服务器(Cloud),作为实车在环(VIL)的纯电动汽车(EV),以及作为模拟HEV子系统的发动机硬件在环实验台架(EIL)和电池硬件在环实验台架(BIL)整合在一起,构成一个具有实车在环的分布式HEV仿真平台(ID-VIL)。这种改进后的仿真平台使原本没有混合动力系统的EV能实时模拟HEV动力系统的输出,而HEV子系统(如发动机和电池)如同工作在HEV实车上一样。最后通过一段里程约为7km的实车市区道路实验和对实验结果的透明度分析验证了ID-VIL系统的可行性和可靠性。

On the basis of existing hardware- in- the-loop （HIL） simulation on hybrid electric vehicle （HEV）,the cloud server as the central control node,the electric vehicle （ EV） as the vehicle- in- the-loop as well as the engine- in- the-loop and battery- in- the-loop test benches as HEV simulation subsystem are integrated by using internet and internet of vehicle with a form of data coupling to compose an internet-distributed vehicle- in- the-loop （ID- VIL） simulation platform. This modified simulation platform enables the EV without powertrain simulate the output of HEV power system and the subsystems of HEV （such as engine and battery） can work just the same as on real HEV. Finally the feasibility and reliability of ID-VIL system is verified by both a 7 kilometers long road testing in urban areas and the transparency analysis on test results.
