  • 在本論文中,即時控制(Real-Time Control)的方法被應用於實現模型電動車的自動倒車入庫系統,主要包含了影像感測器與模糊控制器兩個部分。在影像感測方面,本文是採用造價低廉、設備簡單的影像回授方式進行車輛行走即時狀態的定位。在模糊控制器方面,負責接收來自影像感測器所偵測到的車輛狀態以進行倒車步驟中關於車輛轉角大小的決策分析,最後整合成一套閉迴路控制系統。
    至於整個軟硬體架構主要是利用個人電腦上所搭載的軟體套件,MATLAB/Simulink®而完成即時控制的功能。本文最後會呈現出車輛在不同初始條件下的倒車入庫模擬與實驗結果,並且藉由模擬與實驗結果相互比較下,驗證本套自動倒車入庫系統之可行性。
