Title:
STEERING WHEEL HOLDING POSTURE MONITORING METHOD AND SYSTEM BASED ON TRIBOELECTRIC NANOSENSORS
Document Type and Number:
WIPO Patent Application WO/2023/045189
Kind Code:
A1
Abstract:
A steering wheel holding posture monitoring method and system based on triboelectric nanosensors. The method comprises the following steps: S1, providing a signal monitoring assembly, and when a driver holds a steering wheel, the signal monitoring assembly generating an electrical signal, wherein the signal monitoring assembly comprises a plurality of triboelectric nanosensors, and the triboelectric nanosensors are arranged on a rim of the steering wheel; S2, acquiring a holding posture of the driver, and collecting the electrical signal generated by the signal monitoring assembly when the driver holds the steering wheel, and storing same; S3, constructing a mapping relationship between electrical signals and holding postures according to a collected holding posture and electrical signal data; and S4, collecting, in real time, an electrical signal generated by the signal monitoring assembly when the driver holds the steering wheel and acquiring same in real time, and determining the current holding posture of the driver according to the mapping relationship.
