To provide an electric vehicle drive unit capable of switching a motor operation in accordance with gear shift.SOLUTION: An electric vehicle drive unit includes: a first motor; a second motor; a transmission mechanism coupled to the first motor and the second motor; and a control section for controlling operations of the first motor and the second motor on the basis of a drive signal. The transmission mechanism includes: a sun gear shaft coupled to the first motor; a first planetary gear mechanism; and a one-way clutch for limiting rotating directions of a second planetary gear mechanism and a first carrier to a predetermined normal rotating direction. The drive signal includes: gear shift information indicating a first state where control of the second motor is performed based on torque or a second state where the control of the second motor is performed based on rotating speed; and throttle information indicating acceleration of the rotating speed of a wheel. The control section operates the first motor and the second motor on the basis of the gear shift information and the throttle information.SELECTED DRAWING: Figure 4
