A control apparatus for a continuously variable transmission ensures good acceleration performance during staffing operations, and following an engine stall occurring before a gear ratio of the continuously variable transmission is shifted back to a low speed. The control apparatus includes sensors, a gear ratio return control unit, and a one-way clutch. One sensor detects a gear ratio of a continuously variable transmission. Another sensor detects whether an engine is in a stationary state. The gear ratio return control unit drives a motor in a backward direction when the engine is in the stationary state and the gear ratio of the continuously variable transmission is other than a low gear ratio. The one-way clutch turns idly relative to a backward drive of the output shaft. The gear ratio return control unit brings the motor to a stop when the gear ratio of the continuously variable transmission lowers sufficiently.
