Patent ID: 7492114

Claim:
An electric vehicle drive control device, comprising: an output shaft connected to driven wheels; 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 outputs a rotation whose speed has been shifted to the output shaft; and a controller that: calculates a target rotation speed for the first electric motor based on an engine target rotation speed so that an engine rotation speed does not change before and after shifting; calculates a target torque for the first electric motor based on the target rotation speed for the first electric motor; calculates an inertia compensating torque that compensates for a change in the engine rotation speed caused by inertia while the transmission performs shifting; and corrects the target torque for the first electric motor in accordance with the inertia compensating torque.
