An apparatus for controlling electric car equipped with at least two induction motors (4a-4d) for driving the electric car. The individual motors are connected with variable-voltage variable-frequency inverters (3a-3d) combined with tacho-generators (5a-5d), respectively, to constitute a plurality of drive control units (A-D). And the inverters (3a-3d) of the drive control units (A-D) are all controlled by an integral controller (1). This apparatus for controlling a car includes torque reduction control means for reducing the torque of a predetermined one of the induction motors (4a-4d) by a predetermined value from the command value of the corresponding drive control unit. Frequencies of the inverters of the remaining drive control units are controlled based on the frequency of rotational speed obtained from the tacho-generator of the above drive control unit. <IMAGE> |
