The invention puts forward a torque distribution method of a dual-motor electric vehicle, which comprises that torque required by the vehicle is acquired; the required torque is distributed to a first drive motor and a second drive motor according to multiple distribution proportions, and sum of motor efficiencies corresponding to the first drive motor and the second drive motor under the multiple distribution proportions is calculated; and according to the distribution proportion corresponding to the sum of the maximum motor efficiencies, the required torque is distributed to the first drive motor and the second drive motor in order to make the first drive motor and the second drive motor output corresponding target torque. According to the torque distribution method of the dual-motor electric vehicle, electricity consumption of the vehicle can be reduced, and a driving mileage of the vehicle is brought up. The invention also discloses a torque distribution system of the dual-motor electric vehicle and the vehicle.
