Abstract
A wireless seatbelt monitoring system and method is provided for informing a driver that a seatbelt that should be latched is unlatched. The system includes a wireless seatbelt assembly having a buckle equipped with a piezoelectric element and a transmitter. The transmitter sends a wireless seatbelt status signal when the seatbelt assembly is buckled by harvesting energy during the insertion process. The wireless seatbelt status signal is transmitted to a dedicated repeater module, which retransmits the wireless seatbelt status signal to a receiver. Based upon the wireless seatbelt status signal, the system informs the driver of the status of the seatbelt assemblies audibly, visually, or both.
