The invention provides an electric vehicle dual-drive-axle torque distribution system which comprises a first drive axle, a second drive axle, a third drive axle and a fourth drive axle. A second gearbox and a second motor for driving the second gearbox are arranged on the second drive axle; a controller configured to communicate with the first drive axle and the second drive axle, and calculate a requested torque based on the pedal position and a current vehicle speed, by comparing the working efficiency of the two drive axles when the two drive axles jointly provide the requested torque and the working efficiency of the drive axle when one of the two drive axles provides the requested torque, the number of the drive axles which should work is designated according to the mode that the higher drive axle working efficiency is selected. The invention further provides an electric vehicle dual-drive-axle torque distribution method and a machine readable storage medium, executable instructions are stored on the machine readable storage medium, and when executed by a processor, the instructions implement the method according to the invention.
本发明提出一种电动车辆双驱动桥扭矩分配系统,其包括:第一驱动桥,其上设置有第一变速箱和驱动第一变速箱的第一电机;第二驱动桥,其上设置有第二变速箱和驱动第二变速箱的第二电机;控制器,配置为与第一驱动桥和第二驱动桥通信,并且基于踏板位置和当前车速计算出请求的扭矩,其中,控制器被进一步配置为,通过比较两个驱动桥共同提供请求的扭矩时二者的工作效率以及两个驱动桥其中之一提供请求的扭矩时该驱动桥的工作效率,根据选择更高的驱动桥工作效率的方式指定应该工作的驱动桥的数量。本发明还提出一种电动车辆双驱动桥扭矩分配方法,及一种机器可读存储介质,其上存储有可执行指令,该指令当被处理器执行时实现根据本发明的方法。
