The invention relates to a torque calculation method, device and equipment for a distributed electric vehicle and a medium. The method comprises the steps that torque amplitudes distributed to the left side and the right side of a target vehicle are calculated based on an additional yaw vehicle distance; calculating the sum of residual torques which can be provided by the left side and the right side of the target vehicle based on the directions of the available residual torque and the additional yaw torque of each electric wheel of the target vehicle; calculating first additional torques executed by the left and right sides of the target vehicle based on the torque amplitudes distributed to the left and right sides of the target vehicle and the sum of residual torques which can be provided by the left and right sides of the target vehicle; calculating a second additional torque executed by each electric wheel of the target vehicle according to the residual execution torque and the available residual torque of each electric wheel of the target vehicle; a target torque for each electric wheel is calculated based on the second additional torque for each electric wheel of the target vehicle and the driver intention torque. The service life of the electric wheel is prolonged, and meanwhile the operation stability and safety of a vehicle are greatly improved.
