The invention relates to a fatigue driving early warning method and device, computer equipment and a storage medium. The method comprises the steps that the stepping percentage of an accelerator pedal is detected in real time to serve as the opening degree of the accelerator pedal, and the real-time vehicle speed is detected; when the opening degree of the accelerator pedal is larger than a preset opening degree threshold value and the real-time vehicle speed is larger than a preset vehicle speed threshold value, a fatigue driving detection mode is started; in the fatigue driving detection mode, the accelerator pedal opening degree variable quantity between two adjacent sampling periods is monitored; when the accelerator pedal opening change amount between two adjacent sampling periods is smaller than the accelerator pedal opening change threshold value, counting the accumulated duration when the accelerator pedal opening change amount is smaller than the accelerator pedal opening change threshold value in the current sampling period; and giving out fatigue driving early warning information when the cumulative duration that the accelerator pedal opening change amount is smaller than the accelerator pedal opening change threshold value in the current sampling period is greater than the preset time threshold value.
