Warren, Michigan – General Motors has announced it is working on a new head-up display that would use data gathered from vehicle sensors and cameras and project images directly onto the entire surface of the windshield.
The system, a project of General Motors R&D and several universities, would use an image generated by compact ultra violet lasers projected onto the glass. The system would use night vision, navigation and camera-based sensor technologies to improve driver visibility and object detection ability.
“We’re looking to create enhanced vision systems,” said Thomas Seder, group lab manager of GM R&D. “Let’s say you’re driving in fog. We would use the vehicle’s infrared cameras to identify where the edge of the road is, and the lasers could ‘paint’ the edge of the road onto the windshield so the driver knows where the edge of the road is.”
The enhanced vision systems are a modern take on the head-up display technology that GM first brought to market in 1988. While the full windshield system has not yet been identified for a future GM vehicle program, Seder said that some of the supporting technologies could end up in vehicles in the near future.
Coated with a series of transparent phosphors which emit visible light when excited by a light beam, in this case from a compact laser, the windshield becomes a large-area transparent display, instead of the current head-up systems that use only a small portion of the windshield.
