The invention discloses a front and rear axle driving force adjusting control method and a front and rear axle driving force adjusting control system of a four-wheel drive vehicle, and the four-wheel drive vehicle. The method comprises the steps of obtaining required torque of the four-wheel drive vehicle and SOC (state of charging) of a battery system; obtaining a working mode of the four-wheel drive vehicle according to the required torque of the four-wheel drive vehicle and the SOC of the battery system; calculating required torque of a front axle, required torque of a rear axle and a target gear according to the working mode, the required torque and a current speed of the four-wheel drive vehicle; performing filtering on the required torque of the front axle and the required torque of the rear axle; generating a corresponding front axle torque instruction and a corresponding rear axle torque instruction according to the required torque of the front axle and the required torque of the rear axle after filtering and the target gear; and performing control over the four-wheel drive vehicle according to the front axle torque instruction and the rear axle torque instruction. By applying the method disclosed by the embodiment of the invention, the control algorithm of the four-wheel drive vehicle provided with an active suspension can be simplified, and comfort of the four-wheel drive vehicle provided with an inactive suspension can also be improved, so that the user experience is improved.
