AI Technical Summary
Existing automotive glazing heating systems, such as silver printing wires and metallic coatings, suffer from optical distortions, haze, and flare, particularly in camera fields of view, and are not designed to fit irregular camera obscuration shapes, leading to increased costs and suboptimal performance.
An automotive laminated safety glazing with a heating system integrated between two glass layers, featuring a non-bisymmetrical shape that matches the camera obscuration design, minimizing optical distortions and ensuring the heating system's external contour does not exceed the camera obscuration's external contour when viewed through the glazing.
The solution provides excellent optical performance by minimizing distortions and haze, while allowing for flexible design to match irregular camera obscuration shapes, thus enhancing the effectiveness of the heating system and reducing unnecessary costs.
