Problems solved by technology

Although the technical solution is simple, it only uses the radar in front of the car to judge the distance from the car in front to warn the car driver, without considering factors such as the speed of the car and the environment where it is located, so it is difficult to popularize and apply in practice

Embodiment Construction

[0032] The present invention proposes a dynamic early warning method for preventing rear-end collisions of automobiles. The millimeter wave radar is used to accurately determine the distance to the vehicle in front under the premise of considering the speed of the vehicle. The GPS navigator widely used in automobiles is used to meet preset conditions. A warning signal is issued to the car driver, and the cloud server uses the geographic location information of the GPS navigator to determine the surrounding cars where a car is located, and sends a warning message to notify the drivers of surrounding cars to pay attention to driving, so as to avoid car rear-end accidents as much as possible.

[0033] Such as figure 1 As shown, each car 2 exchanges information with the cloud server 1 through wireless communication.

[0034] Combine figure 2 As shown, the dynamic early warning system for preventing rear-end collision of automobiles proposed by the present invention includes: a cloud se...

Abstract

The invention discloses a dynamic warning method for preventing automobile rear-end collision. The method comprises the steps that distance measurement result data are output through a millimeter-wave radar in each automobile, the distance measurement result data is processed, and a real distance d between an automobile and an automobile in front of the automobile is confirmed; anticollision monitoring is conducted on automobiles according to the real distance d of automobiles; all the automobiles send respective geographical location information and the real distance d to a cloud server, the cloud server judges the position relationships of the automobiles according to the geographical location information sent by automobiles, and when the real distance d of one automobile is smaller than a second safe distance, a second anticollision alerting signal is sent to the automobile and surrounding automobiles. The dynamic warning method for preventing automobile rear-end collision has the advantages that monitoring is accurate, the implement cost is comparatively low, and the use is convenient and practical.

Description

Technical field [0001] The invention relates to the field of automobile safety, in particular to a dynamic early warning method for preventing rear-end collision of automobiles. Background technique [0002] As cars enter thousands of households, the number of cars is increasing year by year. According to statistics, rear-end collisions are the main form of car accidents on highways. According to research conducted by Daimler-Benz, if a driver can get an early warning 0.5 seconds before a collision, 50% of collisions can be avoided; if an early warning is received 1 second, 90% of collisions can be avoided. Therefore, the development of automobile rear-end collision prevention alarm device is to give the driver a warning before a rear-end collision occurs, remind the driver to take measures such as braking or changing lanes to prevent the vehicle from colliding with the vehicle in front, which is helpful to improve the driving safety of the car and reduce the risk of rear-end co...
