Abstract
An electric vehicle drive control device includes a first electric motor; a second electric motor; a differential device that includes first, second, and third rotational elements, wherein the first rotational element is connected to the first electric motor, the second rotational element is connected to the second electric motor via a transmission shaft, and the third rotational element is connected to an engine; a transmission that shifts a speed of a rotation transferred from the transmission shaft; and a controller that: calculates an inertia compensating torque that compensates for a change in a rotation speed caused by inertia while the transmission performs shifting; and corrects a target torque for the first electric motor in accordance with the inertia compensating torque.
