Document Type and Number:
WIPO Patent Application WO/2023/213680
Kind Code:
A1
Abstract:
The present disclosure relates to a system for impact detection on an automotive glazing. The system comprises at least one internal vibration sensor positioned on or in proximity to an internal surface of the automotive glazing and at least one external vibration sensor positioned on an external surface of the automotive glazing, the vibration sensors being configured to measure impact vibration data. The system further comprises a processing unit connected to the vibration sensors, the processing unit being configured to post-process the measured impact vibration data for impact detection. This constitutes an improved system for impact detection on an automotive glazing.
