Hyundai Mobis will showcase its communication lighting concept at CES 2019, which uses an indicating lighting zone to indicate when an autonomous vehicle is operating in self-driving mode. The concept also includes a communication lighting zone that uses LED, digital boards, headlamp projection, and sound to communicate with nearby pedestrians and vehicles during various driving scenarios.

Hyundai Mobis developed the concept to reduce the number of accidents related to the development and testing of autonomous vehicle technology.

Communication lighting can integrate with Mobis’ advanced driver-assistance systems (ADAS) enabled adaptive drive beam (ABD) technology, or AADB—a headlamp innovation announced earlier this year. The company says that the integrated solution offers a more responsive self-dimming headlamp due to increased object detection and processing capabilities, with vehicle-to-vehicle and vehicle-to-pedestrian interaction.

Autonomous vehicles outfitted with communication lighting can reportedly detect a pedestrian from more than 450 ft (137 m) away. Upon detection, headlamps project a bright red warning symbol indicating that is unsafe to motion across the self-driving vehicle.

When the vehicle reaches a complete stop, the headlamps project a crosswalk symbol onto the ground to indicate to nearby pedestrians that it is safe to proceed.

As pedestrians clear the path of the vehicle, LED boards begin signaling when the vehicle is about to resume motion by counting down—similar to traditional crossing signs used today—while showing directional arrows that indicate the direction the vehicle intends to move.

“Light has been used as a conduit for communication among vehicles and pedestrians for almost as long as the automobile has existed, so we are excited to lead the evolution of this technology to save lives and offer peace of mind to all that use the road,” said Mirco Goetz, Director of Lamp Engineering, Hyundai Mobis. “Our primary focus on the safe progression to future mobility will enable our industry to continue the advancement of autonomous vehicle technology, while helping to keep pedestrians and drivers out of harm’s way.”

In addition to the Communication Lighting Experience Zone, Hyundai Mobis will showcase new technology in autonomous driving, infotainment, and eco-friendly vehicle tech at CES 2019, and it will host a presentation on advanced intelligent lighting at booth 3931 in the North Hall of the Las Vegas Convention and World Trade Center on January 8, 2019.
