Title:
DETECTION OF AN IMPACT ON AUTOMOTIVE GLASS
Document Type and Number:
WIPO Patent Application WO/2023/213682
Kind Code:
A1
Abstract:
The present disclosure relates to a computer-implemented method for detection of an impact on automotive glass. The method comprises obtaining, for each respective sensor of at least three sensors, each at a respective predetermined location on or in proximity to the glass, a respective time of flight, at the respective sensor predetermined location, of a vibration wave generated by an impact on the glass. The method further comprises computing an impact location based on the predetermined locations and on the obtained times of flight. This constitutes an improved method for detection of an impact on automotive glass.
