Abstract
A continuously variable transmission control system for a vehicle has a continuously variable transmission device having a belt which is bridged over a driving pulley on a motive power source side and a driven pulley on a wheel side, and an electricity-driven actuator that moves a moveable sheave of at least one of the driving pulley and the driven pulley in the axial direction, to change a width between the moveable sheave and a fixed sheave, a control device that controls driving of the electricity-driven actuator, and an acceleration operation detection unit that detects an operation state of an acceleration operation unit. The control device moves the moveable sheave in the axial direction using the electricity-driven actuator so that a reduction ratio of the continuously variable transmission device is reduced as an amount of operation of the acceleration operation unit is increased at least in a predetermined operation amount range.
