摘要

本研究利用超音波感測器來偵測相對距離與估算側邊碰撞時間（Time-to-collision, TTC），進行設計側邊防撞警示策略，並利用灰色理論來預測目標車輛之距離的改變，達到提早提醒駕駛者碰撞可能性之功能。而此項超音波距離感測器架構之建立，使得車輛具備環境探勘與空間位置解析能力，能建立完整的環境地圖之資訊，其可用於開發停車輔助系統或是自動停車系統，本研究利用兩個以上超音波感測器到障礙物間不同距離之幾何關係，精確的解析出實驗車輛與障礙物間的距離與方位，以做為發展停車輔助系統之環境地圖建置平台。

Since the number of traffic accidents are increasing due to the vehicle density , all the vehicle manufactory companies are invested in the vehicle safety function study .Here , ultrasonic range sensors are employed to detect the relative distance between driving vehicle and that it to estimate the Time-to-collision(TTC) or developing a lateral impact warming system .The Grey theory is employed to predict the vehicle relative distance change for more early driver warming capability . The distance sensing system structure can help a vehicle to detect the around environment and analyze the 2D location for establishing the environment map , addition to the side impact warming system , this 2D environment map can also to used to develop a parking assistant system or an automatic parking system . More then two ultrasonic sensors are employed to detect the geometric relationship between two cars or vehicles and obstacles .Then the relative distance and orientation can be accurately derive for building the environment map.
