The invention discloses a control method of a double-axle electric drive axle, a vehicle and a storage medium. The control method of the double-axle electric drive axle comprises the steps that when a gear shifting request is obtained, a fitting function, a target vehicle speed and a target wheel end torque are obtained; according to the target vehicle speed and the target wheel end torque, a target gear matching pair and a target torque distribution coefficient are determined based on the fitting function; the target gear matching pair comprises a target operation gear of the first electric drive axle and a target operation gear of the second electric drive axle, and the target torque distribution coefficient comprises a target torque distribution coefficient of the first electric drive axle and/or a target torque distribution coefficient of the second electric drive axle; and controlling the first electric drive axle and the second electric drive axle to perform gear switching according to the target gear matching pair and the target torque distribution coefficient. By the adoption of the technical scheme, the cooperative work efficiency of the first electric drive axle and the second electric drive axle can be improved, and the whole vehicle has better economic performance.
本发明公开了一种双桥电驱动桥的控制方法、车辆及存储介质。双桥电驱动桥的控制方法包括:在获取到换挡请求时,获取拟合函数、目标车速以及目标轮端扭矩;根据目标车速、目标轮端扭矩,基于拟合函数,确定目标档位配合对和目标扭矩分配系数;目标档位配合对包括第一电驱动桥的目标运行档位和第二电驱动桥的目标运行档位,目标扭矩分配系数包括第一电驱动桥的目标扭矩分配系数和/或第二电驱动桥的目标扭矩分配系数;根据目标挡位配合对和目标扭矩分配系数,控制第一电驱动桥和第二电驱动桥进行档位切换。采用上述技术方案,能够提高第一电驱动桥和第二电驱动桥的协同工作的效率,使整车体现出更好的经济性能。
