1. A drive control method of a hybrid electric vehicle, comprising:
obtaining a current gear position of the hybrid electric vehicle, a current electric charge level of a power battery and a slope of a road on which the hybrid electric vehicle is driving;
obtaining a current speed of the hybrid electric vehicle if the current gear position of the hybrid vehicle, the current electric charge level of the power battery, and the slope of the road on which the hybrid electric vehicle is driving meet a preset condition; and
causing the hybrid electric vehicle to enter a small load stall mode if the current speed is greater than or equal to a first speed threshold, and less than a second speed threshold.
