Running instant anti-collision warning system and method

Abstract

The invention discloses a running instant anti-collision warning system and a running instant anti-collision warning method. The running instant anti-collision warning method comprises the following steps of: continuously sending running information packets of a vehicle outwards by using a wireless communication module of the vehicle and receiving the running information packets broadcasted by other vehicles; determining whether the surrounding vehicles are in an early warning range of the vehicle according to the information of the running information packets; if the surrounding vehicles arein the early warning range of the vehicle, performing coordinate system conversion between the vehicle and other vehicles and carrying out the steps of classifying collision areas to obtain the coordinate positions of collision points, judging whether the collision points exist or not, calculating collision time and the like, wherein the estimation operation of the collision points is not limitedby the positions of the adjacent vehicles. The running instant anti-collision warning system and the running instant anti-collision warning method can judge the potential hazards from all directions and effectively improve the safety by the anti-collision early warning.

Description

technical field [0001] The present invention relates to a driving instant anti-collision warning system and method thereof, in particular to an instant anti-collision warning system and method for giving warnings to driving vehicles in advance to avoid accidental collisions with other vehicles, thereby improving driving safety. Background technique [0002] There are quite a variety of reasons for traffic accidents, which can be roughly divided into weather and natural environmental factors and purely human factors. Among them, if human factors can be effectively prevented, the probability of traffic accidents can actually be effectively reduced. Therefore the current market has a wide variety of products relevant to driving safety for car owners to select for use in order to improve driving safety. [0003] In various traffic accidents, the degree of injury caused by vehicle collisions is often quite serious and cannot be ignored. Therefore about how to prevent the safety ...

Problems solved by technology

Although the electromagnetic wave device has the advantage of being able to scan a long distance, the electromagnetic wave signal used is directional and cannot be used to detect other vehicles in all directions, and the cost is relatively high

The optical device itself has the advantages of a large monitoring range, but it still has the disadvantages of directionality, distance limitation, and high cost.

Although the acoustic device is cheaper than the above two, its signal transmission distance is limited, and it cannot be applied if the driving speed is fast

Most of the mechanical anti-collision devices are additionally installed on the car body as an emergency protection device when a collision occurs, and cannot achieve any pre-prevention effect

[0004] China Taiwan Invention Patent Announcement No. I284297 "Intelligent Real-time Anti-collision Warning System and Method" discloses that a car broadcasts its driving information to the surrounding vehicles, and receives the driving information broadcast by the surrounding vehicles. The processor judges whether the vehicle will collide with other vehicles according to the driving information of the vehicle. In this patent, the calculation processor uses the vehicle coordinate system to first calculate the relative heading angle, and then uses the moving projection to calculate the possible The collision point, and then use the geometric projection to calculate the moving collision time, as listed in the calculation formulas 9 and 10 in the manual, when calculating the time value T A , T B When , it will involve the tangent function (tan) in the trigonometric function, but when the angle of the tangent function reaches a certain level, its value will change rapidly and gradually diverge

Therefore, the technology used in this patent still cannot be applied to various situations, in other words, it cannot be applied to predict the possibility of collision between other vehicles in any direction and the vehicle, and the practical benefits are limited
