Description
本創作係有關於一種行車記錄器,特別是有關於具車距警示功能之行車導航紀錄器及車距警示方法。 This creation department is about a driving recorder, especially the driving navigation recorder and the distance warning method with the vehicle distance warning function.
工商發達、交通繁忙,車水馬龍川流不息的路口正是現代社會之寫照,而如此亦大幅增加各交通工具肇事之機率。以車代步雖具快速方便之優勢,然而車輛體積重量龐大且移動速度快,如此慣性與衝量皆巨大之物體,於駕駛時無法立刻切換其路徑,一般常理而言,人類平均反應力0.75秒為標準,於各種時速下之反應距離估算,時速60公里時約需要13公尺左右的反應距離,而時速100公里時更需高達21公尺,由此可知行車時稍有不慎便易與他車發生碰撞,且現代人事務繁忙,往往一心多用,或於精神疲憊時,更容易發生事故,而事故發生時為能有效釐清責任歸屬,端賴專業人事之肇事鑑定。 The industrial and commercial development, heavy traffic, and the intersection of traffic and water are the portrayal of modern society, and this has greatly increased the probability of accidents in various vehicles. Although the vehicle is fast and convenient, the weight of the vehicle is huge and the moving speed is fast. Therefore, the object with large inertia and impulse can not switch its path immediately when driving. Generally speaking, the average human reaction force is 0.75 seconds. The standard, the reaction distance at various speeds is estimated, the reaction distance of about 13 meters is required at a speed of 60 kilometers per hour, and the reaction distance is as high as 21 meters at a speed of 100 kilometers per hour, so that it is easy to contact him with a slight accident when driving. Cars collide, and modern people are busy, often multi-tasking, or more prone to accidents when they are mentally exhausted. In the event of an accident, they are able to effectively clarify the responsibility and rely on the identification of professional personnel.
肇事鑑定之難度莫過於證據、資訊有限,由各種零碎之現場狀況,諸如煞車痕、撞擊角度、碰撞程度等資訊,欲還原筆事現場實有一定難度,除需專業人員相當高之輕驗與判斷力之外,尚需耗費許多時日,因此若能完整保留 駕駛行為等資訊,尤其是肇事時間點前一段時間內之資訊,便可有效的加快肇事鑑定之速度,亦可提高準確性。 The difficulty of anecdotal identification is no more than evidence, limited information, from a variety of pieces of on-site conditions, such as vehicle tracks, impact angles, collision levels and other information, it is difficult to restore the scene of the pen, in addition to the need for professionals to test and test In addition to judgment, it takes a lot of time, so if it can be completely retained Information such as driving behavior, especially information for a period of time before the accident time, can effectively speed up the identification of accidents and improve accuracy.
