The invention provides a driven rear axle control system, a driven rear axle and a driven rear axle control method, relates to the field of driven axles, and adopts the scheme that a driving oil cylinder comprises a main oil cavity I, a main oil cavity II, a main oil cavity III and a main oil cavity IV, and the main oil cavity I and the main oil cavity IV are communicated through a steering gear control valve; the steering gear control valve can switch oil inlet and oil return of the first main oil cavity and the fourth main oil cavity, and the steering gear control valve is communicated with an oil tank. A piston rod of the centering oil cylinder is used for being connected with a steering knuckle arm of a rear axle, the centering oil cylinder comprises a first auxiliary oil cavity, a second auxiliary oil cavity, a third auxiliary oil cavity and a fourth auxiliary oil cavity, the first auxiliary oil cavity is communicated with the second main oil cavity through the control valve set, the second auxiliary oil cavity is communicated with the third main oil cavity through the control valve set, and the fourth auxiliary oil cavity is communicated with the third main oil cavity through the control valve set. The third auxiliary oil cavity is communicated with the fourth auxiliary oil cavity. According to the method, the vehicle can actively steer along with the front axle, and the method is suitable for road and off-road working conditions and steering under the low-speed working condition of 60 km/h or below.
