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.

    本发明涉及一种分布式电动汽车的转矩计算方法、装置、设备及介质,其方法包括:基于附加横摆车距计算分配至目标车辆左右两侧的转矩幅值;基于目标车辆每一电动轮的剩余转矩可用转矩和附加横摆转矩的方向计算目标车辆左右两侧分别可提供的剩余转矩总和;基于分配至目标车辆左右两侧的转矩幅值、目标车辆左右两侧分别可提供的剩余转矩总和计算目标车辆左右两侧执行的第一附加转矩;根据目标车辆每一电动轮的剩余执行转矩与剩余转矩可用转矩计算目标车辆每一电动轮执行的第二附加转矩;基于目标车辆每一电动轮的第二附加转矩与驾驶员意图转矩计算每一电动轮的目标转矩。本发明提高了电动轮的使用寿命,同时极大地提高了车辆的操稳性和安全性。
