The invention provides a multi-motor drive axle speed ratio obtaining method and device, equipment and a storage medium, and relates to the technical field of vehicle drive control. The method comprises the steps that according to pre-stored dynamic property output characteristics, an energy consumption calculation model, a load spectrum and an economical efficiency calculation model of the multi-motor drive axle and a pre-stored efficiency characteristic mapping table of each motor, multiple speed ratio combinations and a first economical efficiency index of the multi-motor drive axle under each speed ratio combination are obtained; and a second economic index is determined from the multiple first economic indexes, and the speed ratio combination corresponding to the second economic index serves as the speed ratio combination of the multi-motor drive axle. According to the method, the problem that in the running process of the vehicle, the speed ratio combination corresponding to all the motors in the multi-motor drive axle is single is solved.
