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 comprising: a transmission; a wheel connected to the transmission; a motor in which torque or speed is changed by changing a speed ratio of the transmission; and an electric storage device connected to the motor. A controller is configured to select a first mode if an SOC level of an electric storage device is lower than a predetermined level, and select a second mode if the SOC level of the electric storage device is equal to or higher than the predetermined level.
