The invention provides a fatigue driving detection method and device and steering wheel equipment. The method comprises steps of detecting an electrocardiosignal of a driver in a target time period, and detecting a steering angle of a steering wheel in the target time period; analyzing the electrocardiosignal to obtain a heart rate variability index of the driver; analyzing the steering angle to obtain a steering angle change index; and carrying out information fusion processing on the heart rate variability index and the steering angle change index, and carrying out fatigue driving detectionaccording to a fusion processing result. According to the fatigue driving detection method, the heart rate variability index and the steering angle change index are fused for fatigue driving detection, so fatigue driving detection accuracy is improved, applicability of the fatigue driving detection method is improved, and the fatigue driving detection effect is improved.
