Patent ID: 7762365

Claim:
An electric vehicle drive control device, comprising: 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: controls a rotation speed of the first electric motor so as to suppress a change in an engine rotation speed in conjunction with shifting performed by the transmission; and adjusts electric power consumptions generated in the first and second electric motors, by controlling an output supplied to the second electric motor such that a net sum of power being used between the first electric motor and the second electric motor is zero in conjunction with the control of the rotation speed of the first electric motor in an inertia phase in the shifting.
