The invention discloses a torque vector control method and device, a storage medium and a vehicle, additional yaw moment is calculated by taking yaw velocity and a side slip angle as control targets, target longitudinal force of each wheel is calculated by taking optimal tire adhesion rate as a target function in combination with the additional yaw moment and a preset constraint condition, and the torque vector control method and the torque vector control device are realized. The size and the direction of the motor torque are controlled, the stability of the vehicle is controlled by controlling the motor torque, it can be guaranteed that the dynamic property of the vehicle cannot be attenuated, and it can also be guaranteed that the stability of the vehicle is controlled in time.

    本发明公开了一种扭矩矢量控制方法、装置、存储介质和车辆,通过以横摆角速度和质心侧偏角作为控制目标,计算出附加横摆力矩,并以轮胎附着率最优作为目标函数结合附加横摆力矩和预设的约束条件计算出各个车轮的目标纵向力,以对电机扭矩的大小及方向进行控制,通过控制电机扭矩对车辆进行稳定性控制,既能保证车辆动力性不会衰减,也能保证及时对车辆进行稳定性控制。
