逆向差速齒輪式複合電動汽車之建置與研究
Establishment and Study of Hybrid Electric Vehicle of Inverse-Differential Gear
摘要
本文主要是利用三菱汽車的VERYCA改裝成複合電動系統實驗車，藉由控制單元Woodward MotoTron，切換複合動力系統之四種動力模式之能量管理驗證（馬達模式、內燃機模式、雙動力模式及剎車能回充模式）。 本研究針對逆向差速齒輪式複合電動車動力切換技術為研究主體，硬體採用一體式馬達/發電機及傳統內燃機作為動力源。當駕駛者欲行駛車輛時，根據電子油門踏板被踩下時所產生的電門訊號及車輛行駛速度作為參考依據，判斷要以何種動力模式下進行動力策略，並且擷取車載電池之殘餘電量決定動力模式切換之優先順序，於使用的過程中擁有完善的控制策略。最後將整體VERYCA實驗車架上底盤動力計測試，以即時監控方式觀察各元件的運轉狀況與性能輸出情形，最後依據其訊號與參數，進行NEDC2000、FTP75、台北市市區及高雄市市區等四種標準行車型態測試汽車的性能與油耗，不僅能確實掌握實驗車實際的運轉情況及預防可能發生的故障問題，同時也提供事前保養與維修的能力，以達到有效降低維護成本與節省時間，增加整體系統的可靠度，最後進行實車路試，完成逆向差速齒輪式複合電動車。

The research refits Mitsubishi VERYCA to be the experimental vehicle with hybrid electric system, and by controlling the Woodward MotoTron unit, this hybrid power system can be switched into four power modes (Motor mode, Engine mode, Dual power mode, and Regenerative Braking mode), and the power management of each mode will be tested and verified. This research is aimed to study the power switching technique of the inverse differential gear type of hybrid electric vehicle; the hardware of the vehicle adopts the integrated motor/generator and traditional Internal Combustion Engine (ICE) as its power source. When the driver wants to drive the vehicle, the system would take the switch signal, which produced by stepping on the electronic gas pedal, and the driving speed as reference to judge which power strategy should be adopted under which power mode; moreover, the power mode switching priority will be decided according to the SOC (State of Charge) of the battery tracked by the system, thus to ensure a flawless control strategy. We put the whole VERYCA experimental vehicle onto the chassis dynamometer for testing, and through the immediate monitor to observe the operating condition of each unit and their output performance. Finally, we take the signals and parameters as reference to test the performance and fuel consumption of the vehicle in four standard driving patterns, which are: NEDC2000, FTP75, Taipei city area and Kaohsiung city area. By doing so we can not only ensure a full understanding of the actual operating condition of the experimental vehicle but also prevent those possible problems that may cause a breakdown; in addition, we can also provide advance maintenance and repair, thus to efficiently decrease the maintaining cost, save time, and increase the reliability of the whole system. Lastly, we would have an actual field test to complete the inverse differential gear type of hybrid electric vehicle.
