摘要

電動輔助轉向系統及主動式轉向系統為近幾年車輛轉向系統之熱門開發方向，本研究深入探討相關資料之機構型式、系統架構與研究目標，進而評估電動輔助轉向系統及主動式轉向系統的相關性質，開發整合電動輔助轉向系統與主動式轉向系統之轉向機構。本研究針對小齒輪轉向系統型式做整合機構之研究，分析行星齒輪機構合成的整合機構，不僅能達到電動輔助轉向系統之要求，也能滿足主動式轉向系統之功能，並以減少機構體積與節省馬達功率為考量。本研究將分析後之整合機構延伸於獨立轉向系統，除了提供動力輔助外，藉由參考方向盤轉角與車速，提供不同的轉向比與轉向幾何，使車輛在低速時以阿克曼轉向幾何進行轉向；高速時以平行轉向方式進行轉向，以提高行駛時的穩定性與操控性，讓轉向系統擁有更好的操控與安全之性能。

Nowadays electric power steering system and active front steering system are popular developed. By studying the purposes, characteristics, and mechanism types of these two steering systems, this paper utilizes a plantary gear set to integrate electric power steering system and active front steering system. The proposed mechanism applied on the pinion type steering system not only satisfy the requirement of electric power steering system but also supply the function of active front steering system, and then reduce the mechanism space needed and save the energy consumption of motor. This paper extends the proposed idea to independent steering system. It can supply power assistance and variable steering ratio to each of front wheels by referring to the angle of steering wheel and vehicle speed. Let vehicle carry out Ackerman steering geometry at low speed cornering and parallel steering geometry at high speed cornering so as to increase stability and safety of vehicle handling.
