PURPOSE:To quicken rise of torque of an output shaft by compensating an actuation amount to decide to the small side of a speed change ratio the more, the longer a detection time is in the case when the actuation amount of an electric actuator is on the large side of the speed change ratio rather than a target actuation amount at the time of down-shift. CONSTITUTION:Presupposed is a speed change control device of a stepless speed changer which has a target speed change ratio decision means to decide a target speed ratio in accordance with a driving condition and an actuation amount decision means of an electric actuator, which has an open loop actuation amount decision means and a closed loop actuation amount decision means to decide a closed loop actuation amount in accordance with deflection between the target speed change ratio and an actual speed change ratio. Then, a time after a throttle opening comes to be more than a specific amount is detected by a time detection means, and in the case when an actual actuation amount of the electric actuator is on the large side of the speed change ratio rather than the target actuation amount at the time of down-shift, the longer the time is, the more the actuation amount of the electric actuator decided by the actuation amount decision means is corrected to the small side of the speed change ratio by an actuation amount correction means. |
