The invention discloses a dual-motor torque distribution control method, a dual-motor system, a vehicle, electronic equipment and a storage medium. The dual-motor torque distribution control method comprises the steps that the current rotating speeds of two motors and the total torque required by the dual-motor system are obtained; according to the current rotating speeds of the two motors and the total required torque of the dual-motor system, a pre-stored torque distribution coefficient MAP table is inquired to obtain the optimal torque distribution coefficient under the current working condition, and the torque distribution coefficient MAP table is the mapping relation of the rotating speeds of the two motors, the total required torque of the dual-motor system and the optimal torque distribution coefficient; and distributing the torque of the two motors according to the optimal torque distribution coefficient. By adopting the method, the torque can be distributed to the corresponding motors according to the torque distribution proportion with the highest total efficiency of the two motors through the torque distribution coefficient MAP table of the motors, the torque distribution proportion with the optimal efficiency is found, and the operand is reduced.
