摘要： A shift control apparatus for a continuously-variable transmission includes an operating condition sensing section; a normal-time speed ratio determining section; a normal-time control section; a kickdown-acceleration request determining section; a kickdown-acceleration-time control section; and an accelerator-operation-quantity variation-rate limiting section. The kickdown-acceleration-time control section is configured to set a kickdown-acceleration-time target speed ratio in accordance with a vehicle speed and an accelerator operation quantity, to cause an output rotational speed of the transmission to increase substantially linearly with an increase of input rotational speed of the transmission, when the kickdown-acceleration request determining section determines that a kickdown acceleration request is present, and to control the speed ratio in accordance with the kickdown-acceleration-time target speed ratio. The accelerator-operation-quantity variation-rate limiting section is configured to calculate a corrected accelerator operation quantity by imposing a limitation on a variation rate of the accelerator operation quantity, when a predetermined variation of the sensed accelerator operation quantity occurs during the speed ratio control of the kickdown-acceleration-time control section, and to output the corrected accelerator operation quantity to the kickdown-acceleration-time control section in order to set the kickdown-acceleration-time target speed ratio.
