The invention relates to a multi-mode dual-motor power coupling driving system which comprises a first motor, a second motor, an input shaft I, an input shaft II, a double-row planetary gear mechanism, a brake, a planetary gear shell, a power output transmission mechanism and a differential mechanism. The first motor is connected with a gear ring of the double-row planetary gear mechanism through an input shaft I, the second motor is connected with a sun gear of the double-row planetary gear mechanism through an input shaft II, and the brake brakes a rear planet row planetary frame in the double-row planetary gear mechanism. And the power output transmission mechanism transmits power output by the double-row planetary gear mechanism to the whole vehicle for driving. According to the dynamic coupling driving system, four driving modes and multiple driving working modes can be achieved, more motors can work in an efficient interval on the premise that the driving dynamic property requirement is met, and therefore the working efficiency of the driving system is further improved.
