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

Electric-vehicle control device and control method

An automatic transmission controller which provides smooth shifting of gears and reduces gear shifting-caused shocks during a change in speed. There is provided a control means whereby, when gear shifting of the automatic transmission is decided during a switch-on of an air-conditioning unit, then the air-conditioning unit is kept on at least during the aforesaid gear shifting. Further, the control means selects an air conditioner-on-mode timer table in order to actuate the transmission in a controlled manner, and then to control a rev-up state of the engine speed.
