Vehicle rear-end collision preventing device

Abstract

The invention belongs to the field of the automatic control of automobiles, and particularly relates to a vehicle rear-end collision preventing device. The vehicle rear-end collision preventing device comprises a detection sensor, a GPS (global positioning system) navigator, a central processor, a road condition display device and an automatic controller; the detection sensor is mainly used for transmitting detected barrier information of a front road section to the central processor inside a vehicle, the GPS navigator is also installed inside the vehicle, the central processor is used for analyzing and processing the front barrier information transmitted by the detection sensor and an instant road section diagram inputted by a GPS navigation map and supplying the processed road condition information to a driver through the road condition display device; when the road condition information cannot be processed by the driver in time or is improperly processed by the driver, the vehicle continuously runs towards a barrier, the central processor can transmit a command to the automatic controller so as to automatically operate a brake device to brake in time, and the rear-end collision accident can be prevented. By adopting partial technological means of a pilotless vehicle, rear-end collision and even various accidents can be conveniently prevented by adding the simple device to an ordinary vehicle; the device is simple, convenient to operate, easier to popularize, low in price and wide in market prospect.

Description

technical field [0001] The invention belongs to the field of automatic control of automobiles, in particular to an anti-rear collision device for vehicles. Background technique [0002] All over the world, on highways, car rear-end collision accidents caused by foggy weather often occur, and even serial rear-end collisions occur, ranging from a few dozen vehicles to as many as dozens of vehicles colliding together, which is terrible. The reason is mostly due to the driver's unclear identification of the road conditions ahead due to heavy fog and improper handling. [0003] Many countries in the world are developing intelligent or even unmanned vehicles. Through a variety of high-tech means, such vehicles can not only identify heavy fog and prevent rear-end collisions, but also automatically drive on many complex road sections and even streets. However, some road sections are too complicated, various vehicles, pedestrians, those who follow the order, those who do not fo...

AI Technical Summary

Problems solved by technology

However, some road sections are too complicated, various vehicles, pedestrians, those who follow the order, those who do not follow the order, and various accidents. Driverless cars need to take into account too many emergencies, so it is still in the research and experiment stage. , there are few vehicles on the market, and even if there are a small number of vehicles on the market, they cannot be popularized at present due to their complex structure and high price.

[0004] For automobile rear-end collision accidents caused by heavy fog, so far, there is no good solution in the world, and many highways are often closed due to heavy fog
