有鑒於全球能源逐漸匱乏，國際油價不斷上漲，如何有效節約能源並找尋新的
替代能源來減少化石燃料的依賴，實為當前急需解決的問題。大量使用化石燃料背
後，對環境有害之污染也隨之上升，近幾年溫室效應所帶來的衝擊遠大於我們所想
像，所以此等議題已不容再忽視。其中溫室氣體部份又以CO2 與HC 為最大宗，所
以若能藉由混合動力的方式驅動車輛，不但有助於溫室效應之改善，並亦可提供車
輛所需之動力。混合動力車輛中，常常需要模式切換，在大多數混合動力車輛中離
合器正是模式切換最重要的部分，藉著離合器的接合或釋放，就可以達成模式切換
的功能。不過離合器要順利接合有許多條件需要考慮，像是兩端轉速、推動離合器
推力等。若一瞬間推動離合器力道太大，可能會導致離合器磨損、能量損耗或是使
乘坐者察覺車輛的頓挫感；兩端轉速相差太大，也可能會使接合時間變太長，近而
延緩模式切換所需時間。有鑒如此，本計畫乃利用華創車電股份有限公司所提供之
離合器來達成混合動力車輛的模式切換，並以液壓系統為基礎，藉著電磁閥控制進
油量，推動離合器達成接合或分離。由於離合器模式切換時，會導致離合器兩端轉
速變化，且接合時間的長短也可能會對整體傳輸效能有影響。因此，需要進行離合
器控制，期望在接合時間最小化，兩端轉速差異量最小化下，達成離合器平順化接
合的目標。而上述提及的控制發展，必須先藉由建立一個控制模型，並由華創車電
股份有限公司所提供之離合器平台驗證後，根據此控制模型，來發展控制器設計。

In view of the global energy scarcity, rising international oil prices, how to effectively save
energy and find new alternative energy sources to reduce dependence on fossil fuels, is currently
an urgent problem to be solved. With the increasing use of fossil fuels, pollution that
is harmful to the environment has also risen. In recent years, the impact of the greenhouse
effect is far greater than we thought, so these issues can no longer be ignored. CO2 and HC
are the most important part of the greenhouse gas. Therefore, if we can use hybrid way to
drive the car, it will not only help to improve the greenhouse effect, but also provide energy
application. In a hybrid vehicle, it is often necessary to switch the mode, and in many systems
the clutch is the most important part for the mode switching. By means of the clutch
engagement or disengagement, the mode switching function can be achieved. The clutch
must be smoothly engaged while controlling the slip ratio and the clutch thrust force. If the
force applied to the clutch is raised instantaneously, it may lead to clutch wear, energy loss
and vibration. On the other hand, if the engagement duration is too long, it may delay the
mode switching process. In view of this, based on the clutch system provided by HAITEC, a
hybrid vehicle mode switching control strategy will be developed. Specifically, the solenoid
valves will be used to control the pressures in the hydraulic system so as to achieve smooth
engagement and disengagement of the clutches. As the mode switching control will lead to
changes in speed at both ends of the clutch and the bonding time may also affect the overall
transmission performance, it is necessary to develop a controller that achieves the goals of minimizing the engaging time and reducing the slip ratio. For the purpose of the above
mentioned control development, a controloriented
model for the clutch system will be first
developed and validated using the platform provided by HAITEC. Based on the model, an
adaptive control algorithm can then be developed.
