A requested cruise-control horsepower calculator (33) of a shift control device obtains a requested cruise-control horsepower from a speed difference between a target cruising vehicle speed and an actual vehicle speed. A requested cruise-control torque calculator (34) obtains a requested cruise-control torque based on the requested cruise-control horsepower and an engine rotation speed. A cruise-control accelerator-opening calculator (37) sets a cruise-control accelerator opening by referring to an engine torque map where a cruise-control accelerator-opening characteristic curve is set along an equal horsepower line based on the requested cruise-control torque and the engine rotation speed. A target primary rotation-speed calculator (25) sets a target primary rotation speed by referring to a shift-line map based on the cruise-control accelerator opening and the actual vehicle speed. A shift controller (26) obtains a target gear shift ratio based on the target primary rotation speed and the actual vehicle speed to perform shift control.
