設計與實現自動跟車系統

在論文中，我們提出一套為高速公路所設計的車輛駕駛系統，名為“自動跟車系統”，未來駕駛者在高速公路行駛時，不再需要親自操作車輛，即可安全抵達目的地。此自動跟車系統的實驗模擬環境具備無線區域網路WiFi、紅外線距離感測器、CMOS視訊鏡頭、組裝模型車，我們以WiFi無線網路做為遠端監控中心與車隊之間的溝通管道，於行車時可透過無線網路，主動將控制指令轉傳給車隊成員做為駕駛系統參考之用，同時將車隊前方道路狀況回傳給遠端監控中心，並利用裝配在車輛前方的距離感測器，使車隊成員藉由收集車距數據，自動修正車輛速度快慢以及方向調整。整個系統設計的目的是為了提供駕駛者更便利、安全、節能、省時的旅程經驗。

In this thesis, we propose a new vehicle driving system, named the Automatic Car-Following System, for future freeway by which drivers no longer need to manually control, to follow the front car in the same path. The Automatic Car-Following System consists of a Wi-Fi network, CMOS cameras, Infrared distance sensors, and Electric cars. Use the Wi-Fi network as communications among the Leading car, the Follower car and the Remote monitor center. Vehicle members can get control command from the Remote monitor center by Wi-Fi, the Follower car uses Infrared distance sensors to get the distance to its leading car. If the follower car has offset or the distance is outside a pre-defined range then the Automatic Car-Following System will modify the follower cars speed and direction. The design goal of the whole system is to provide safety and convenience driving experience.
