Intelligent electric vehicle V2V communication system based on LED visible light communication

Abstract

The invention discloses an intelligent electric vehicle V2V communication system based on LED visible light communication. The system comprises a visible light transmitting unit and a visible light receiving unit, wherein the visible light transmitting unit converts some electrical signals generated in a VCU into optical signals by using high-speed modulated visible light emitted by a vehicle-mounted LED as an information carrier, and transmitting the optical signals to free space; the optical light receiving unit uses a transparent glass type solar panel to detect the visible light, receives an optical carrier signal, decodes to acquire vehicle information and sends the information to the VCU. Compared with the prior art, the system provided by the invention builds communication between the vehicles by sending and receiving the optical signals, and is simple in operate, free of electromagnetic interference and high in reliability. Meanwhile, the system provided by the invention adopts the transparent glass type solar panel to serve as a collection device of the optical signals, and integrates the effects of being transparent, shielding wind, charging and collecting signals, so that arrangement of hardware is greatly reduced, and hardware cost and energy are saved.

Description

technical field [0001] The invention belongs to the technical field of electric vehicle communication, and in particular relates to an intelligent electric vehicle V2V communication system based on LED visible light communication. Background technique [0002] With the development of battery technology and the spread of the concept of environmental protection and energy saving, electric vehicles are increasingly favored by consumers, and they are also projects strongly supported by the government. The design of electric vehicles is becoming more and more intelligent. In addition to the intelligent system of the bicycle, the intelligent communication system between vehicles is also very important. The communication between vehicles can share some data information, so that the front, rear, left, and right vehicles can make correct responses according to the received information. [0003] At present, research on V2V (vehicle-to-vehicle, vehicle-to-vehicle) communication mainly...

AI Technical Summary

Problems solved by technology

The communication system is also based on visible light, but new devices need to be added to receive light, and a new control module needs to be designed, which requires a large investment in hardware, and after receiving signals from other vehicles, it cannot be directly made. emergency response

At the same time, the system only satisfies the communication function between vehicles and does not involve energy storage.
