The invention provides a driving system, a motor control method and a power-assisted electric vehicle. The driving system comprises a gearless motor which directly outputs torque, a power source which is used for providing current for the gearless motor, and a vector controller which is connected with the gearless motor and the power source respectively and is used for controlling the torque and reluctance of the gearless motor through controlling the current vector of the current. According to the technical schemes of the invention, weak magnetic control technologies are adopted; the current vector of the current which is transmitted to the gearless motor by the power source is changed through the vector controller, so that an excitation magnetic field can be enhanced, and therefore, the reluctance of the gearless motor can be decreased, and the gearless motor can be applied to the power-assisted electric vehicle, and thus, problems such as high cost, low efficiency under low load and large possibility of being worn of a change gear can be solved.
