The invention discloses a four-wheel drive hybrid electric vehicle travelling power generation control method, which comprises the following steps: when the four-wheel drive hybrid electric vehicle enters a travelling power generation mode, a slip rate of the four-wheel drive hybrid electric vehicle, an opening of an accelerator pedal, a vehicle speed and a steering wheel rotation angle signal are acquired; when the slip rate is judged to be in a preset range, the four-wheel drive hybrid electric vehicle is controlled for front-wheel drive and rear-wheel power generation with the ground as a coupling point, and according to the opening of the accelerator pedal of the four-wheel drive hybrid electric vehicle, the vehicle speed and the steering wheel rotation angle signal, torque for front-wheel drive and torque for rear-wheel power generation are distributed. According to the travelling power generation control method, the ground serves as the coupling point to enable the four-wheel drive hybrid electric vehicle to realize front-wheel drive and rear-wheel power generation, characteristics of large power of the rear-wheel motor are made full use of, the working efficiency of the engine can be optimized in the case of travelling power generation, and fuel economy of the four-wheel drive hybrid electric vehicle is improved. The invention also discloses a power system for the four-wheel drive hybrid electric vehicle.
