MEMS Laser Projection Enhances Automotive V2X Communication

Exterior vehicle lighting is evolving beyond illumination toward communication and interaction, particularly in advanced driver assistance and connected mobility systems. In this context, Infineon Technologies AG and Valeo are collaborating on a short-range ground projection module using laser beam scanning, presented at the 2026 Auto Beijing exhibition in China.

From lighting to communication interfaces
The system integrates Infineon’s two-dimensional Micro Electro Mechanical Systems (MEMS) mirror and controller into Valeo’s high-definition projection module. This configuration enables precise control of laser beams to generate projected images on the ground with increased brightness, contrast, and resolution.

Such performance characteristics are required to maintain visibility in daylight conditions, a key limitation of earlier projection-based vehicle lighting systems. The initial implementation supports bi-color output, with a roadmap toward full-color projection in future iterations.

Technical role of MEMS in laser beam scanning
The MEMS mirror operates by dynamically directing laser beams across a defined projection area, enabling high-resolution image formation without traditional optical projection components. This approach reduces system size while maintaining image clarity, making it suitable for integration into vehicle body structures.

By combining MEMS actuation with dedicated control electronics, the system achieves stable scanning patterns and consistent image rendering, which are critical for safety-related signaling applications.

Applications across automotive lighting and interaction systems
The ground projection module is designed for integration into passenger vehicles, where it can support both functional and user experience features. Examples include projecting visual cues such as welcome or exit signals, brand identifiers, or contextual information adjacent to the vehicle.

This aligns with broader developments in the automotive data ecosystem, where vehicles are expected to communicate status and intent not only internally but also externally to users and surrounding environments.

Extending V2X communication to the physical environment
The system also supports vehicle-to-everything (V2X) communication by projecting dynamic, context-aware information directly onto road surfaces. Potential use cases include visual warnings for braking events, pedestrian crossings, or lane-change intentions.

Unlike traditional V2X systems that rely on digital communication between connected vehicles, ground projection provides a visible interface that can be interpreted by pedestrians, cyclists, and drivers of non-connected vehicles. This creates an additional communication layer that complements existing safety systems.

Validation at Auto Beijing 2026
The joint solution was presented at Auto Beijing 2026 (April 24 to May 3), held in Beijing, China, where it was demonstrated as part of Valeo’s lighting portfolio. The collaboration reflects ongoing efforts to integrate sensing, projection, and communication technologies into unified vehicle systems.

Deployment of such projection-based communication features remains subject to regulatory approval, particularly for safety-critical signaling functions.
