次複合動力機車之動態模擬與性能分析
Dynamic Simulation and Performance Analysis for a Mild Hybrid Scooter
摘要
低耗能與低廢氣為目前車輛發展之趨勢，為減低機車造成之都會區空氣污染，考量低耗能與機車成本之競爭力因素，將傳統機車之啟動馬達與發電機以啟動馬達發電機(ISG)系統取代，設計一種擁有傳統機車架構與複合動力機車特性之次複合動力機車(Mild Hybrid Scooter)，以取代傳統汽油引擎機車。本研究旨在以Matlab/Simulink為基礎，建構出完整之反向式次複合動力機車與傳統汽油機車之動態模式，其利用引擎實驗實際量測及參考相關文獻建立ISG馬達與引擎的數據為基礎，以邏輯控制觀念建立模糊控制器，使用機車行駛的車速、機車扭力和電瓶殘電量三個輸入條件作為動力分配的依據，建立模糊規則庫和邏輯法則，使動力來源能得到適當的能量管理分配，建立之模型可計算次複合動力機車與傳統機車之燃油經濟性與污染排放。模擬結果顯示，在ECE行車型態的燃油經濟性上，MHS機車，比一般傳統機車改善13.68%，在排污方面，對於CO排放可改善11.07%、HC可改善16.57%，NOx可改善17.4%。

Fuel consumption and air pollution in vehicle idling and starting are two import issues for vehicles .To have high fuel econo my as well as low exhaust emission and cost , an innovative mild hyid scooter (MHS) is proposed in this research.In the proposed MHS an integrated starter/generator (ISG) is used instead of the individual starter and generator in a conventional motorcycle.The purpose of this study is based on Matlab/Simulink to aim full backward-facing mild hybrid scooter and conventional motorcycle dynamic modles.It is used engine experiment and refer to correlative reference to set up ISG motor and engine data to build and set up the fuzzy controller with the logic control idea, use speed, motorcycle torsion and state of charge(soc) of battery.Rules of fuzzy and logic control were being set for different operating conditions, for the purpose of more effective output power managerment.The model set up can be calculated fuel economy of the traditional motorcycle and disposal of pollutants.The simulating results deicted that the MHS can improve 13.68% of fuel economy compared with the conventional motorcycle.As for the exhaust emissions,thecentrations of CO HC and NOx are reduced by 11.07%、16.57% and 17.4,respectively.
