When the temperature of operating fluid of an actuator is low, a target input rotation speed lower limit value NinL is set. The lower limit value NinL is greater than a lower limit value set for a normal temperature of operating fluid. A target input rotation speed Nint is calculated from the state of running of a vehicle, such as the amount of operation of an accelerator, the vehicle speed, etc. If the target input rotation speed is lower than the lower limit value NinL, the target input rotation speed is reset to the lower limit value NinL. As a result of a control that includes the above-described steps, the speed ratio gamma becomes relatively high before the vehicle stops. Therefore, even if the speed ratio-changing rate is low, the speed ratio gamma can be brought to or near a maximum value gammamax before the vehicle stops. Thus, reductions in the speed ratio-changing rate caused by low temperature of the operating fluid of the actuator can be curbed.
