Hyundai Mobis Introduces Innovative HD Lighting System for Enhanced Nighttime Driving

Hyundai Mobis Co. has developed a next-generation headlamp dubbed the HD Lighting System that can project driving information onto the road surface, including the speed limit and upcoming road construction.

The system utilizes front camera sensors or navigation to detect driving information and then projects it onto the road surface in real time using letters or figures. For example, a construction site ahead would prompt the lamp to display a 1.5-meter wide "under construction" symbol on the road surface, 15 meters from the driver's field of view. It also provides information on speed limits, speed bumps, and expressway ramp directions.

The advanced lights greatly enhance drivers' awareness of their surroundings during nighttime driving, reducing accident risks. The lamps also project a virtual crosswalk sign onto the road at night for pedestrian safety.

The HD Lighting System comprises HD microLEDs and a digital micromirror device (DMD), which serves as a reflector and light source. Around 25,000 microLEDs in the lamp enable precise light control and accurate object and pedestrian identification.

The concept of headlights that project shapes is not new. Mercedes-Benz gave a similar demonstration in 2018 with the Maybach S-Class luxury automobile's digital headlights on its. They claimed that these programmable million-pixel lights could, among other things, portray trails through road construction or employ arrows to highlight pedestrians.

Shape-projecting headlights were demonstrated by Ford engineers in Europe in 2022, along with a number of potential applications, such as alerting drivers to potentially dangerous road conditions, illuminating approaching turns, and displaying a way around bicycles. The benefit of this technology, according to Ford, is that it displays information directly in front of the driver's line of sight, as opposed to on a screen, which forces drivers to take their eyes off the road.

Hyundai Mobis, however, also hinted at possible uses in autonomous vehicles. According to a Hyundai Mobis spokesperson, in the era of autonomous driving, software technology that integrates numerous auto components into a single device will be more important than ever.
