The invention discloses a dual-motor driving system and a vehicle, and belongs to the technical field of vehicles. The dual-motor driving system comprises a first motor, a first transmission mechanism, a first coupling mechanism, a second motor, a second transmission mechanism, a second coupling mechanism, a third transmission mechanism and a differential mechanism. The first motor is in transmission connection with the first transmission mechanism; the first coupling mechanism is in transmission connection with the first transmission mechanism; the output power of the second motor is smaller than that of the first motor, the second motor is in transmission connection with the second transmission mechanism, and the second coupling mechanism is in transmission connection with the second transmission mechanism; the third transmission mechanism is in transmission connection with the first coupling mechanism, the second coupling mechanism and the differential mechanism. The power source of the vehicle is changed through the first coupling mechanism and the second coupling mechanism, and the power output of the vehicle wheels is adjusted to meet different requirements of the vehicle in various working conditions, so that the working efficiency of each motor is improved, and the endurance mileage of the vehicle is increased.
