The invention relates to a multi-motor, multi-scheme and multi-driving-mode driving system, which comprises at least two driving devices consisting of motors and speed regulation devices, one first driving device and N auxiliary driving devices, and is controlled by a motor control device, so that the driving devices can controllably cooperate or independently work to generate at least three gears of driving modes, in each driving mode, the ratio of the output power of the driving device A is between 575 per mill and 666 per mill; the sum of the proportions of the output power of the N auxiliary driving devices is between 333 per thousand and 425 per thousand, and the proportion ratio of the adjacent gears is controlled between 1.35 and 2 (times), so that a driving mode with a plurality of gears and different total proportion ratios can be formed by combining a smaller number of motors, the dynamic property and the economical efficiency of electric driving machinery can be ensured, and the manufacturing cost
