V2X Lighting for Autonomous Vehicle Communication

Integrated vehicle lighting that can simultaneously provide both functional lighting for vehicle operation and communication signals. The system has a single lamp assembly with multiple lights that can be selectively activated based on separate determinations for vehicle lighting needs and communication needs. This allows the vehicle to use the same lighting hardware for both purposes without needing separate dedicated lighting systems. The system can, for example, turn off some lights for functional lighting while activating others for communication signals or vice versa. This enables multimodal lighting functionality from a single lamp assembly.

Communicating a vehicle's driving status to pedestrians and surrounding vehicles using the vehicle body itself as a communication medium. The system detects if an object is approaching within a certain distance. When an object is nearby, it displays the vehicle's driving status, like braking or turning, through external lights on the vehicle body. This allows pedestrians and other drivers to see the vehicle's intended path and actions before they interact. It expands the communication range beyond just headlights and signals.

A wireless system to transmit traffic light signals from a central control system to vehicles without relying on line-of-sight visibility. The traffic light control system has a wireless transmitter that sends the signal to a receiver in the vehicle's advanced driving assistance system (ADAS). The receiver decodes the signal and provides it to the ADAS for display. This allows vehicles to receive traffic light information even if physical obstructions block their view of the actual lights. The signals are synchronized and interpreted by the ADAS to provide real-time traffic guidance.

Communication devices for self-driving cars to interact with pedestrians and other drivers. The device uses ring-shaped lights around the headlights that change shape to mimic eye contact when the car communicates. The lights have LEDs that can be selectively turned on to create different shapes. When the car is self-driving, the lights change based on the communication to indicate intentions. This provides clearer and more intuitive communication compared to just turning on all the lights. The lights can also be covered by a lens that darkens the non-lit areas to make the changing shapes more visible.

A vehicle-road lighting system that uses V2X communication to improve lighting safety while preventing glare. The system involves vehicles communicating with smart roads. The roads receive vehicle info and generate lighting control and headlight suggestion based on driving conditions. The roads send lighting control to onboard modules and headlight suggestions to vehicles. The vehicles then adjust headlights accordingly. This allows coordinated, optimized lighting that prevents glare for oncoming vehicles and pedestrians. It also simplifies headlight design versus traditional adaptive systems.

Vehicle communication system that allows vehicles to obtain road information using optical communication instead of onboard sensors. The system involves vehicles receiving visible light information from roadside lights and other vehicles' lights using a receiver. A processor identifies the light sources and obtains traffic condition info. The processor then controls the vehicle's own lights to emit specific visible light patterns based on the source and condition. This allows vehicles to communicate road info using stable external light sources instead of onboard sensors. The system can also receive modulated visible light information from roadside devices.

Vehicle illumination devices to indicate inter-vehicle communication between autonomous vehicles to improve safety when manual and automated vehicles coexist. The device has lights that can flash a pattern when one autonomous vehicle communicates with another. This visual cue alerts pedestrians and other vehicles that the communicating vehicles are coordinating and can help prevent collisions. The communication is initiated by a master vehicle, and other vehicles respond. The master vehicle flashes its lights to indicate communication.

Vehicle lighting control system that improves safety by intelligently adjusting the headlights based on external information received from other vehicles and infrastructure. The system uses communication with other vehicles and base stations to obtain information about nearby pedestrians, curves, ramps, intersections, etc. This information is used to generate optimized lighting instructions for the vehicle's headlights. The controller then sends the instructions to the headlight actuators to adjust the light shape, intensity, and aiming to provide appropriate illumination for different scenarios. This provides more accurate and effective lighting compared to just using the onboard camera for scene analysis.

A system for transmitting/receiving traffic signal information using visible light communication (VLC) to improve autonomous vehicle operation. Smart traffic lights transmit traffic signal information like current, remaining time, and next signal using VLC. Cameras on autonomous vehicles detect the signals and demodulate them to restore the traffic info. This allows the vehicle to anticipate and prepare for upcoming signals, avoiding sudden stops and accelerations. The VLC signals are encoded and modulated using methods like OOK, VPPM, and CSK to prevent flicker and enable accurate decoding.

Intelligent traffic light with self-powered wireless communication capability to transmit information to vehicles for improved road safety. The traffic light has a photovoltaic panel to generate power, a light sensor to detect sunlight intensity, and a wireless transmitter. The light uses visible light communications (VLC) in the visible spectrum for data transmission. The sensor monitors sunlight intensity. If it's high, the light reduces its VLC transmission speed to avoid interference. This maximizes robustness in sunny conditions. If sunlight is low, the light increases VLC speed for faster data transfer. This adaptive transmission speeds based on lighting conditions improves VLC reliability.

Intelligent highway lighting system that uses vehicle-to-vehicle communication to optimize lighting based on real-time traffic conditions. The system has lights along highways that can be turned on or off based on data received from nearby vehicles. If the data shows traffic exceeding a threshold, the lights are illuminated. This reduces unnecessary lighting when roads are empty. The lights can also be triggered by vehicles indicating they are within a certain radius, indicating an approaching vehicle. This provides targeted illumination where needed instead of constant lighting. The lights communicate with vehicles via vehicle-to-vehicle protocols to receive traffic data.
