摘要

本論文提出車輛行駛狀態主動回報系統以提升車輛行駛的安全性。車輛行駛於道路上往往可能因人為疏忽或是視線上的死角，無法在事故發生前做出最適合的應變措施，導致事故發生，輕者車輛損傷，重者造成生命的危害。目前車輛安全設備已經發展得非常先進，某些車廠還研發出主動剎車系統，避免駕駛者在沒注意前方路況的情形下，突然有行人或車輛出現，或是沒有保持安全距離的環境下，能夠自主啟動強制剎車之動作，以減少事故的發生。
現有車輛的設計只有對當下行駛之方向執行輔助保護動作，如果發生在轉彎或是連續彎路的情況下，除了部份車用照明配備有主動轉向式頭燈系統(AFS)外，車輛在轉彎前就預先判斷駕駛者將要駛入的道路環境並預做分析的功能則較少見。本論文提出一套車輛行駛狀態主動回報系統以提升車輛行駛的安全性，透過微處理器連接電子感應器，分析比對感應器所傳回之訊號，判斷車輛將何時要進入下一個彎道，且立即告知行車電腦馬上執行防護措施，以預防事故發生。
此獨立系統以接近類人工智慧的方式與行車電腦連結，不但不會增加原行車電腦的負荷，更可提升車輛的安全性。且該系統的架構單純，元件取得容易價格也低廉，與車廠配合性高，只需確認兩系統的溝通格式，便可立即連接使用，是一個可即刻商業化之系統。

This thesis presents a vehicle driving state auto-feedback systems (VDSAFS) to enhance the security of vehicle driving. When a vehicle is driven on the road, people can not make the most appropriate contingency measures, because of careless or a dead space taken place in front of drivers. Therefore, the accident is arisen, which leads to vehicle damages and, more seriously, causes the danger of the life. Currently, vehicle safety equipment has been developed very advanced. Some vehicle factories also develop active braking system to avoid the case when the drivers are driving on the road and do not pay attention to the road conditions, a pedestrian or vehicle appeared suddenly or the case of failing to maintain a safe distance from the environment, the vehicle can be forced to activate braking system to reduce the occurrence of an accident.
The design of existing vehicle only performs assistant protection for current moved direction. For the case of turning or consecutive turning, in addition to part of the vehicle lightings installed with adaptive front lighting system (AFS), the function that vehicle pre-judges and analyzes the road environment for drivers before turning is relatively rare. This thesis then proposes a VDSAFS to enhance the security of vehicle driving. Through connecting between microcontroller (MCU) and electronic sensors, the system can analyze and verify the feedback signals transmitted from sensor to judge when the vehicle will enter the next turning. It immediately informs the vehicle computer to perform protective measures and then prevent the possibility of car accident.
Such stand-alone system connects with vehicle computer by the way of near artificial intelligence. It not only does not increase the loading of the original vehicle computer, but also enhance the security of vehicles. The structure of the proposed system is simple, components are obtained easily, cost is low, and it has high compatibility with factory. It can be connected and used immediately, only to identify the communication format between VDSAFS and vehicle computer. Hence, VDSAFS is capable of commercializing at once.
