The invention discloses a motor controller control method special for a range extender. The method comprises the following steps: S1, establishing a rotating coordinate system based on a motor rotor of the range extender; S2, obtaining reference currents of a d axis and a q axis in the rotating coordinate system in the step S1 by displaying a lookup table; S3, enabling the q-axis reference currentto be subjected to amplitude limiting, q-axis current superposition correction, a quadrature-axis current controller and feedback processing in sequence, and then outputting a quadrature-axis voltage; enabling the d-axis reference current to be subjected to amplitude limiting, d-axis current superposition correction, quadrature-axis current controller and feedback processing in sequence, and thenoutputting a direct-axis voltage. Through the combination of a multidimensional table look-up technology (LUT) and a voltage feedback adjustment method, the function of deep flux weakening control ofthe motor is realized.
