Abstract:
1. A kick-down shift control device for an electric vehicle, the electric vehicle being capable of travelling by motor torque inputted from an electric motor through an automatic transmission in compliance with an amount of depression of an accelerator pedal, the kick-down shift control device comprising: a controller that restricts an upper limit value of the motor torque increasing in compliance with depression of the accelerator pedal upon carrying out kick-down shift toward a low-side gear ratio of the automatic transmission in association with depression of the accelerator pedal by determining a rotation speed of the electric motor at a time at which an inertia phase, in which a ratio of input rotation speed of the automatic transmission and output rotation speed thereof is changed toward the low-side gear ratio, is ended and restricting the upper limit value of the motor torque to a level based on the determined rotation speed of the electric motor at a time at which the inertia phase is ended.
