The embodiment of the invention discloses a motor torque distribution method and device, equipment and a medium. The method comprises the following steps: determining motor parameter data of a vehicle according to driving data and torque distribution data of the vehicle, and determining the total efficiency of an electric drive axle according to the motor parameter data; in the at least two groups of torque distribution data, determining the torque distribution data when the total efficiency of the electric drive axle is the highest as calibration torque distribution data; and establishing a corresponding relation between the driving data and the calibrated torque distribution data, determining target torque distribution data corresponding to the current driving data of the vehicle according to the corresponding relation between the driving data and the calibrated torque distribution data, and performing torque control on a motor of the vehicle through the target torque distribution data. According to the technical scheme, the torque distribution data when the total efficiency of the electric drive axle is the highest is determined in advance, and the corresponding relation between the driving data and the calibrated torque distribution data is established, so that efficient control can be achieved when the vehicle is subjected to motor torque control.
