A front and rear vehicle warning anti-collision system based on visible light communication technology

Abstract

The invention discloses a front and rear vehicle prompt anti-rear-end collision system based on visible light communication technology, which includes a light sensor array for detecting the distance between target vehicles and the color of road traffic lights, and sending detection information; a camera group for collecting The picture information of the light slogan of the front taillight, and send the picture information; the taillight control module; the data processing module, used to process the road traffic light information and the vehicle distance detected by the light sensor array, and transmit it to the taillight control module, and Process the flashing frequency of the front and rear lights and the picture information collected and sent by the camera group, and then display it on the man-machine interface; the light status control circuit. The present invention detects the distance between target vehicles and the color of road traffic lights through visible light, sets up taillights and slogans of cars, and recognizes the lights and slogans of front taillights through a camera group, thereby greatly improving driving comfort and safety.

Description

technical field [0001] The invention relates to the field of automobile rear-end collision prevention, in particular to an anti-rear-end collision system for prompting front and rear vehicles based on visible light communication technology. 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 lam...

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, if there are many vehicles in front, or there are large vehicles in front, it will lead to the situation that traffic lights cannot be seen
