Document Type and Number:
Japanese Patent JP6410000
Kind Code:
B2
Abstract:
An electric vehicle drive device includes: a first motor; a second motor; a transmission mechanism coupled to the first motor and the second motor; and a control unit configured to control operation of the first motor and the second motor based on a drive signal. The transmission mechanism includes: a sun gear shaft coupled to the first motor; a first planetary gear mechanism; a second planetary gear mechanism; and a one-way clutch configured to restrict a rotation direction of a first carrier to a predetermined positive rotation direction. The drive signal includes gear change information indicating a first state in which the second motor is controlled based on torque or a second state in which the second motor is controlled based on rotation speed, and throttle information indicating an acceleration of rotation speed of a wheel. The control unit operates the first motor and the second motor based on the gear change information and the throttle information.
