A speed change control system that suppress a change in a vehicle behavior, and prevents a reduction in an energy efficiency. The speed change control system is applied to a vehicle (EV) comprising: a transmission (4); a wheel (7) connected to the transmission (4); a motor (1) in which torque or speed is changed by changing a speed ratio of the transmission (4); and an electric storage device (2) connected to the motor (1, 11). A controller (8) is configured to select a first mode if an SOC level of an electric storage device (2) is lower than a predetermined level (Th1), and select a second mode if the SOC level of the electric storage device (2) is equal to or higher than the predetermined level (Th1).
