The invention provides a fatigue driving behavior detection method and a fatigue degree judgment model training method. The detection method comprises the following steps: acquiring inertial measurement data acquired by an inertial measurement unit arranged on a steering wheel; steering wheel rotation angle separation and gravity factor elimination are carried out to obtain steering wheel rotation angle data and linear acceleration data; performing feature extraction on the steering wheel angle data and the linear acceleration data to obtain fatigue features and vehicle operation features; the fatigue features and the vehicle operation features are input into a fatigue degree judgment model for fatigue degree recognition, and a fatigue driving behavior detection result is obtained; and performing fatigue reminding according to a fatigue driving behavior detection result. Only one inertial measurement unit installed on the steering wheel is adopted to collect inertial measurement data, the inertial measurement data are processed, fatigue detection is achieved in combination with the trained fatigue degree judgment model, fatigue reminding is conducted on a driver, and cost is low.
