The invention discloses a double-motor electric drive system and method for a commercial vehicle, and belongs to the field of new energy automobiles, the system adopts a double-motor structure, double motors provide power, a first shaft is connected with a driven transmission assembly through a gear shifting assembly to achieve direct gear output, or the gear shifting assembly connects an active transmission assembly with the driven transmission assembly to achieve direct gear output. And finally, the power is transmitted to the differential mechanism through the passive transmission assembly so as to drive the whole vehicle, through switching of multiple gears and direct gears, when the vehicle runs at a high speed, the direct gears can be selected to achieve high-efficiency running, the transmission efficiency is improved, and the cruising ability can be improved. Through reasonable matching of parameters of the two motors and the speed ratio of the gearbox, the two motors can work in an efficient area under most working conditions, electric energy is saved, and the endurance mileage of the vehicle is increased; the system is simple in principle, can meet various working conditions, and has good popularization and application values.
