Abstract:
An electric vehicle control device is provided that ensures a required coupling capacity precision of a friction coupling element by appropriately switching a torque sharing rate during a shift transition period. The control device includes a motor, an automatic transmission, a shift controller, a frictional engagement element, a control unit and an engagement capacity control section. The frictional engagement element is disposed in a power transmission path from the motor to a driving wheel. The control unit switching delays switching a torque sharing rate of the frictional engagement element during a shift transition period until the start of the shifting procedure, and continuously switches the current gear sharing rate to a subsequent gear sharing rate in accordance with a degree of the shifting procedure when the shifting procedure starts.
