Abstract

In a specific state where an electric vehicle is in a stop state and a creep torque is generate in an electric motor (2), when a shift range is switched from a traveling range to a non-traveling range, a motor control section (10B) performs a torque decrease control to stepwisely decrease the creep torque of the electric motor (2), and an automatic transmission control device (30) performs a disengagement control to gradually disengage the frictional engagement element of the automatic transmission (3).
