Prewarning anti-collision device and method for vehicle

Abstract

The invention discloses a prewarning anti-collision device and method for a vehicle. The prewarning anti-collision device comprises a GPS (Global Positioning System) unit, an information transmit-receive control unit, a communication unit and a prewarning unit, wherein the GPS unit is used for acquiring the positioning information of the vehicle and sending the positioning information to the information transmit-receive control unit; and the information transmit-receive control unit continually receives the information of the vehicle, continually sends the information of the vehicle to the outside through the communication unit, continually receives the information of other vehicles, compares the information of the vehicle with the information of other vehicles and sends a collision prewarning signal to the prewarning unit. By adopting the prewarning anti-collision device for the vehicle, a driver can still accurately judge the conditions of vehicles nearby when the personal visual system feels that the front of the vehicle is blurred by rain and fog, sand and dust, and barriers; and information communication among vehicles is provided to bring convenience for the driver to accurately make a driving decision in a very short time, so that the alarm dispatching time is saved, the driving safety factor is improved and a life saving role can be played in emergency.

Description

technical field [0001] The invention belongs to the field of vehicle networking control, and in particular relates to a vehicle early warning and anti-collision device and method. Background technique [0002] There are many reasons for traffic accidents, which can be roughly divided into natural environmental factors and purely human factors. Among them, natural environmental factors are difficult to change. If human factors can be effectively prevented in advance, the probability of traffic accidents can actually be effectively reduced. [0003] Low visibility has always been one of the main causes of traffic accidents. Heavy fog or heavy rain will cause rapid reduction in visibility, seriously affecting the driver's sight, and is the enemy of traffic safety. The heavy fog is pervasive, which seriously affects traffic safety. Because the vehicles cannot run normally, it will also lead to traffic accidents of rear-end collisions and serial collisions. There are many preca...

Problems solved by technology

We cannot change the natural environmental factors. Although the above artificial methods can reduce the impact of heavy fog on traffic safety, they are not very effective.
