A warning device for front and rear vehicles preventing rear-end collision on expressway

Abstract

The invention discloses a device for reminding front and back vehicles for preventing rear-end collision on an expressway. The device for reminding the front and back vehicles comprises a light ray sensing array, which is used for detecting space of a target vehicle; a camera group, which is used for collecting a light-shown slogan of a tail light of a front vehicle; a sensor group, which is used for detecting the monitoring scale of the camera group; a data processing module, which is used for receiving the image data of the space and slogan of the tail light of the front vehicle, and the data backup of monitoring scale, and then converting the image information, distance information and the monitoring scale data to voice data; a data sending module; a man-machine operation interface; a voice broadcasting module. Through detecting the space of the target vehicle by visible light, setting the indicated slogan of the tail light of the automobile, identifying the slogan of the tail light of the front vehicle by the camera group while converting the data to voice information to broadcast, the driving comfort level and safety are greatly improved, and the purpose of preventing the rear-end collision is realized; besides, the device can vividly and directly display the light-shown language so as to provide warning information of safe driving for a driver of the back vehicle.

Description

technical field [0001] The invention relates to the field of automobile rear-end collision prevention, in particular to a front and rear vehicle prompting device for preventing rear-end collision on an expressway. Background technique [0002] In the existing automotive lighting and signal control system, when the driver depresses the brake pedal, the brake light switch is closed, and the brake tail light and high-position brake light of the car are turned on; when the driver toggles the turn signal switch, the The turn signals light up accordingly; when the driver puts the reverse gear, that is, the reverse light switch is closed, the reverse lights light up. Different car lights represent different light language. [0003] In the normal driving of the front and rear cars, the tail light group of the front car will display different signal lights according to the different operations of the driver on the car signal light switch. However, the lamps are only controlled by i...

AI Technical Summary

Problems solved by technology

However, the lights are only controlled by independent switches, and the amount of information is single, so they cannot synthesize the basic driving state of the car and provide more comprehensive information for the driver behind.

At the same time, the light has only two states of on and off, the warning effect provided is not good enough, and the occurrence of traffic accidents cannot be effectively avoided

Finally, the traditional lighting control system mostly adopts relay or independent switch mode control, which makes the wiring harness in the car too much and the wiring is complicated, which will cause serious electromagnetic interference to the system and reduce the reliability of the system

[0004] At the same time, most of the existing radar-vehicle distance test devices are only used when parking, and the alarm will only be issued within the specified distance, so in the process of high-speed driving, it is easy to cause rear-end collisions, and most of them have alarm lags problem, low security
