This control device: selects, as a mode-switch gear change line when switching an auxiliary transmission mechanism from a first gear position to a second gear position, a first mode-switch gear change line that prioritizes learning the hydraulic pressure at which a low brake starts to slip and learning the hydraulic pressure at which a high clutch begins to transmit torque, or a second mode-switch gear change line that is a gear change line lower than the first mode-switch gear change line and prioritizes engine fuel-saving performance; and switches the auxiliary transmission mechanism from the first gear position to the second gear position on the basis of the selected mode-switch gear change line. 作为将副变速机构从1速向2速切换时的模式切换变速线，选择以低速制动器开始滑动的油压的学习、及高速离合器开始扭矩传递的油压的学习为优先的第模式切换变速线、或者比第模式切换变速线更靠低挡侧的变速线且以发动机的燃耗性能为优先的第二模式变速线，基于所选择的模式切换变速线，将副变速机构从第速向第二速切换。
