Optical Based Real Time Vehicle to Vehicle Communication System for Self Driving Vehicles

Current work introduces an optical-based real-time vehicle-to-vehicle (V2V) communication system tailored for self-driving vehicles. This system relies on LED transmitters and camera receivers equipped with a specialized optical communication image sensor (OCI). Such OCI features a “communication pixel” for swift response to changes in light intensity and an “LED flag image” output circuit, effectively highlighting high-intensity light sources, including LEDs. This advanced technology enables the camera receiver to achieve a remarkable 10 Mb/s optical signal reception as well as real-time LED detection. Through rigorous testing under actual driving conditions and varying outdoor lighting, the system proves its reliability, ensuring robust LED detection using the flag image method, even in challenging scenarios.
