Hybrid electric vehicle, drive control method and device of the same

A drive control device of a hybrid electric vehicle, comprising:

• a first obtaining module, configured to obtain 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;
• a determining module, configured to determine whether the hybrid electric vehicle is within a taxiing start-stop interval according to the current gear position of the hybrid electric vehicle, the current electric charge level of the power battery, and the slope of the road on which the hybrid electric vehicle is driving;
• a second obtaining module, configured to obtain a current speed of the hybrid electric vehicle, if the hybrid electric vehicle is within the taxiing start-stop interval;
• and
• a first control module, configured to control the hybrid electric vehicle to enter a small load stop mode if the current speed is greater than or equal to a first speed threshold, and less than a second speed threshold;
• and configured to control the hybrid electric vehicle to enter a small load stall mode if the current speed is greater than or equal to the second speed threshold, and less than a third speed threshold.
