Title:
VEHICLE BODY VIBRATION REAL-TIME DETECTION SYSTEM, AND VEHICLE
Document Type and Number:
WIPO Patent Application WO/2023/077301
Kind Code:
A1
Abstract:
A vehicle body vibration real-time detection system, and a vehicle, the system comprising: a plurality of piezoelectric sensors (102a-102m), which are attached to a plurality of vehicle outer surface components (103), and are used for collecting vibration signals of the corresponding vehicle outer surface components (103); sampling circuits (104a, 104b), which are electrically connected to the piezoelectric sensors (102a-102m), and are used for sampling electrical signals that are output by the connected piezoelectric sensors (102a-102m); and a controller (105), which is electrically connected to the sampling circuits (104a, 104b), and is used for processing sampling signals that are output by the sampling circuits (104a, 104b), extracting features of the vibration signals, and determining a vehicle outer surface component (103) to which a vibration source corresponds and/or an impact type to which the vibration source corresponds. Thus, a site where a specific collision or damage occurs can be better determined, and since comprehensive determination is performed, dependence on a signal threshold is also reduced, such that more information can be provided for making a more complex determination and response.
