improve automobile safety, identifying driver fatigue is considerably
crucial because it is one of the main causes of traffic accidents.
In this research, smart systems based on a triboelectric nanogenerator
are designed, which can provide driver status monitoring and fatigue
warning in real time. The smart system consists of a self-powered
steering-wheel angle sensor (SSAS) and a signal processing unit. The
SSAS, which comprises a stator, a rotor, and a sleeve, is mounted
on the steering rod, and the electrodes are designed with a phase
difference to improve the resolution of the sensor. The turning angle
of the steering wheel operated by the driver is recorded by the SSAS;
meanwhile, the number of rotations, the average angle, and other parameters
in the driver’s recorded data are analyzed by the signal processing
unit from which a warning threshold for each parameter is determined.
The system assesses the status of the driver in real-time by comparing
these parameters and threshold values, and experimental results demonstrate
that driver status is accurately judged. This work has important potential
applications in the fields of traffic safety and intelligent driving.
