摘要

本論文針對插電式混合動力電動車之動力系統進行力矩分配策略研究，並運用車載資通訊技術，以達到智慧化節能行駛之目的。本論文提出兩種不同控制架構。第一種偏向傳統力矩分配策略，僅針對力矩分配比例進行控制，控制策略結合兩種不同控制方法，並運用車載資通訊技術來提升表現。模擬結果顯示所提出之控制策略表現非常接近相同成本函數下之全域最佳解。第二種控制架構則不同於以往力矩分配策略，此架構中駕駛者模型會以一速度最佳化控制器取代，速度最佳化控制器會根據車身狀態與車載資通訊系統所提供之訊息來調整車速，目的是讓馬達系統運作於高效區間。結果顯示速度最佳化控制器能夠進一步提升約5%~10%之能耗表現。
論文中首先以模型迴路模擬(Model in the loop simulation)進行控制策略驗證，模擬環境會根據實驗數據與理論資料建立，如此來確保模擬真實性。研究中會進一步將控制策略燒錄到即時系統中，進行控制迴路模擬(control in the loop simulation)，以驗證控制器實踐於實車系統之可行性。

This thesis aims at developing a torque distribution strategy for an intelligent plug-in hybrid electric vehicles using Telematics. This research proposes two different kinds of control structure. The fisrt one is similar to traditional torque distribution strategies, it focuses on finding the optimum split ration of the powertrain system, the proposed control strategy combines two different control strategies, and make use of Telematics to futher improve the performance. The simulation shows that the result of proposed control strategy is very close to that of a global optimum method, and is 15%~20% better than other control strategies. The second structure is dictinct from normal torque distriburion strategy, it replaces the driver model with an optimum speed controller. The function of the optimum speed controller is to find a speed profile according to the status of car and information provided by Telematics, the goal is to make the system operates at its highest efficiency zone. The result shows that the optimum speed controller will futher improve 5%~10% of the perforamce.
The proposed control strategies are tested in model in the loop simulation, simulation environment is established based on experimental data to ensure the verisimilitude of the simulations. The propsed control strategies are futher compiled to a real time environment to verify the feasibility of implementing in real car systems.
