The invention provides an integrated driving system. The system comprises a motor which comprises a shell and an output shaft, and a planetary gear transmission mechanism which comprises a first-stage planetary gear mechanism and a second-stage planetary gear mechanism, the first output torque of the first-stage planetary gear mechanism is transmitted to a driven object, the second output torque of the first-stage planetary gear mechanism is transmitted to the second-stage planetary gear mechanism, and the third output torque of the second-stage planetary gear mechanism is transmitted to the driven object. The invention further provides an electric vehicle comprising the integrated driving system. According to the integrated driving system, the large transmission ratio is achieved, two-stage distribution of torque can be achieved, and therefore the load capacity of the vehicle can be improved.
