Description

Driving navigation recorder and distance warning method with vehicle distance warning function

This creation department is about a driving recorder, especially the driving navigation recorder and the distance warning method with the vehicle distance warning function.

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.

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.
