Abstract:

A non-invasive driving fatigue state identification method based on the surface electromyographic signals of the driver's legs is proposed. Firstly, the electromyographic signal of the tibialis anterior muscle of the driver's right leg is collected through a simulated driving fatigue experiment, and the fatigue status is marked through a subjective evaluation scale. Secondly, a variational mode decomposition algorithm is used to filter out noise on the surface electromyographic signal, and 12 time-frequency domain eigenvalues ??are extracted from the five IMF components obtained by decomposition. Finally, a driving fatigue state discrimination model based on whale algorithm optimized support vector machine is constructed. The results show that this method has a good discrimination effect on three fatigue states, with an accuracy of more than 84%.
