Automobile safety reminding device

Abstract

The invention relates to an automobile safety reminding device. The safety reminding device includes a warning device, laser rangefinders and a computer chip; the three laser rangefinders are arrangedon the two sides of the head of an automobile and the center of the head of the automobile respectively; laser sent by the laser rangefinders is parallel to the forwarding direction of an automobilebody; the laser rangefinders measure the distance between the head of the automobile and a barrier on the front every a seconds; the computer chip is used for recording the transmission distance of each laser rangefinder respectively, the computer chip processes the distance values every b seconds to obtain time values, and the time is output on a display screen. When the output time exceeds the safety range, the computer chip is communicated with the warning device so as to remind a driver. The reminding device is small in structure and unique in principle, can timely remind the driver of thedriving situation of vehicles in front of the driver, effectively avoids the occurrence of rear-end collision, reduces traffic accidents, and ensures safe and smooth driving on a highway.

Description

technical field [0001] The invention relates to an auto accessory, in particular to a safety reminding device. Background technique [0002] With the popularization of automobiles, automobile traffic accidents are also gradually increasing, especially on expressways, where automobiles are traveling at a faster speed, and chain collisions are likely to occur when traffic accidents occur, causing serious casualties and causing traffic jams. Seriously affect the passage of passing vehicles and cause great pressure on traffic. High-speed traffic accidents can be described as a serious disease of the traffic network; one of the reasons for high-speed traffic accidents: the vehicle in front decelerates, which is not obvious from the rear, causing the reaction time of the driver behind Extended, and when the rear vehicle finds the situation, it may be too late to brake to avoid danger; the reason is that the size of the front vehicle observed by the rear driver is small, and as the...

[0002] With the popularization of automobiles, automobile traffic accidents are also gradually increasing, especially on expressways, where automobiles are traveling at a faster speed, and chain collisions are likely to occur when traffic accidents occur, causing serious casualties and causing traffic jams. Seriously affect the passage of passing vehicles and cause great pressure on traffic. High-speed traffic accidents can be described as a serious disease of the traffic network; one of the reasons for high-speed traffic accidents: the vehicle in front decelerates, which is not obvious from the rear, causing the reaction time of the driver behind Extended, and when the rear vehicle finds the situation, it may be too late to brake to avoid danger; the reason is that the size of the front vehicle observed by the rear driver is small, and as the distance gets closer, the vehicle model gradually becomes larger; when the two vehicles are far apart , the size of the car model is not obvious when the distance is shortened, but when the cars are very close, the car model will change significantly. At this time, the driver behind can feel it sensitively. In this case, the reaction is not timely. The driver of the car behind is very likely to hit the car in front, causing a safety accident
