Systems and methods for detecting passenger restraint device usage

Abstract

Systems, methods, and other embodiments described herein relate to ensuring proper usage of passenger restraint devices. In one embodiment, a method includes controlling the millimeter-wave (mm-wave) radar sensor to transmit mm-wave radar waves toward a seat of a vehicle. The method also includes 1) detecting, from reflected mm-wave radar waves, an arrangement of a concealed metallic marker within a passenger restraint device of the seat relative to a passenger in the seat and 2) estimating an expected arrangement of the passenger restraint device relative to the passenger. A notification is generated responsive to the reflected mm-wave radar waves indicating that the arrangement of the passenger restraint device is different than the expected arrangement of the passenger restraint device.
