The invention discloses a hybrid electric vehicle and a driving power generation control method and device.The hybrid electric vehicle comprises a power battery, a driving motor, an engine and a power generator connected with the engine. Acquiring gradient information of the target road, consumed power of vehicle accessories, actual consumed power of a driving motor and uncompensated driving generated power; acquiring ramp compensation generation power according to the gradient information; according to the ramp compensation generation power, the vehicle accessory consumption power, the actual consumption power of the driving motor and the non-compensation driving generation power, the driving generation total power is obtained; and performing power generation control on the engine and the generator according to the driving power generation total power. Therefore, when the vehicle is subjected to driving power generation control, the corresponding ramp compensation power generation power is obtained according to the gradient information of the target road, so that the battery electric quantity of the whole vehicle during driving on the ramp is ensured, and the driving experience of a user is optimized.
