The invention provides a driving power generation method, device and equipment and an engineering vehicle, and the driving power generation method comprises the steps that when the vehicle is in a driving power generation mode, the engine demand torque percentage is obtained; when the engine demand torque percentage is smaller than a first threshold value, target generated power is determined according to a preset first mapping relation; and controlling a generator to generate power according to the target generated power. By the adoption of the technical scheme, the power generation power of the generator can be dynamically adjusted according to the required torque percentage of the engine, the generator can generate power within the better energy efficiency interval of the engine, mechanical energy is provided for the generator while the engine consumes less fuel oil, and the energy efficiency of the generator is improved. In addition, the power generator can generate power in a high-efficiency interval of the power generator, the power generator can generate power while consuming less mechanical energy, efficiency matching of the power generator and the engine is achieved, the power generation efficiency and the fuel oil utilization rate are improved, and vehicle oil consumption is reduced.
