The invention discloses a torque distribution method, device and equipment for a double-electric-drive-axle vehicle and a medium. The method comprises the following steps: acquiring performance parameter information corresponding to a front electric drive axle and a rear electric drive axle; torque efficient interval parameters corresponding to the front electric drive axle and the rear electric drive axle are determined through a preset electric drive axle torque bench test; and the driver demand torque is obtained, and distribution torques corresponding to the front electric drive axle and the rear electric drive axle are determined based on the driver demand torque, the performance parameter information, the torque efficient interval parameters and the torque distribution rule. According to the embodiment of the invention, the torque required to be distributed on the front electric drive axle and the rear electric drive axle is determined through the performance parameter information corresponding to the front electric drive axle and the rear electric drive axle, the torque required by a driver is not reduced, meanwhile, the driving torque of the double electric drive axles is reasonably distributed, and the driving efficiency of the double electric drive axles is improved. And the driving efficiency of each electric drive axle is improved, so that the economical efficiency of the vehicle is improved.
