The invention discloses a double-electric-drive-axle slipping torque distribution method, device and system, a VCU and a medium. The method comprises the steps of obtaining a steering wheel steering angle, an accelerator pedal opening degree and a vehicle speed; determining an electric drive axle driving mode according to the steering wheel steering angle, the accelerator pedal opening degree and the vehicle speed; wherein the electric drive bridge driving mode comprises a double-electric drive bridge driving mode, a first electric drive bridge driving mode and a second electric drive bridge driving mode; in the double-electric-drive-axle driving mode, a first target torque distribution mode is determined according to the slip rate of each electric drive axle; in the driving mode of the first electric drive axle, a second target torque distribution mode is determined according to the slip rate of the first electric drive axle; and in the second electric drive axle driving mode, a third target torque distribution mode is determined according to the slip rate of the second electric drive axle. According to the scheme, the vehicle slip limiting function in different driving modes is achieved, and meanwhile the problems of poor driving feeling, drifting and the like caused by step change of power output are solved.

    本发明公开了一种双电驱桥打滑扭矩分配方法、装置、系统、VCU及介质。该方法包括:获取方向盘转向角、油门踏板开度及车速;根据所述方向盘转向角、油门踏板开度及车速确定电驱桥驱动模式;其中,所述电驱桥驱动模式包括双电驱桥驱动模式、第一电驱桥驱动模式及第二电驱桥驱动模式;在所述双电驱桥驱动模式下,根据各电驱桥滑移率大小确定第一目标扭矩分配方式;在所述第一电驱桥驱动模式下,根据第一电驱桥滑移率大小确定第二目标扭矩分配方式;在所述第二电驱桥驱动模式下,根据第二电驱桥滑移率大小确定第三目标扭矩分配方式。本方案实现了不同驱动模式下车辆限滑功能,同时防止动力输出阶跃性变化导致的驾乘感受差及甩尾等问题。
