本論文旨在設計具有主動安全架構之車門防撞裝置，本研究主要防止汽車駕駛不當開門，亦即鏡頭感測器一旦偵測行車後方有移動物體之際，即以最快速度完成車門制動，俾於即時防護騎士用路安全。本文設計控制器通訊系統進行擷取車用區域網路系統資料，掌握汽車行車狀態資訊，再經由鏡頭偵測辨識後方移動物體，輔以完成齒條結構咬合之車門鎖門機制需求。而為驗證本系統之實際應用可行性，本文經由控制電路實作、機構實現及影像辨識功能實測結果可知，本系統確臻車門主動安全功能，研製成果具有可行性與應用參考價值。

The thesis is aimed to propose an active security design for the collision prevention of vehicular doors. For the scenario when the mirror detects any moving object behind the vehicle, then the braking of car door will be immediately performed so as to ensure the security of motor riders. In this study, by acquiring the data from the controller are network via the communication system of controller, it helps to grasp the moving status of vehicle. This is then followed by the image detection and recognition of moving objects in order for the operation of rack occlusion such that the active security requirement of door-locking mechanism can be satisfied. To verify the practical value of this proposed design, hardware realization of control circuits along with software simulation of image recognition are both completed with extensive tests. Experimental results support the feasibility of this proposed approach, benefiting the active security design of vehicles.
