A control device, in which a shift-up control is automatically executed when an engine's over revolution with a turbine speed for a shift gear set by a manual shift mode exceeding a preset limit speed A is executed, is configured such that a controller detects an engine's over revolution (Yes in step s2), and cancels the shift-up control (step s8) when detecting a closing change of an accelerator opening by a specified angle (Yes in step s5) during a period of time from an output timing of a shift-up command (step s4) to specified timing of an inertia phase start I (Yes in step s6).
