VEHICLE

A vehicle includes: an engine; auxiliary equipment that is driven by the engine; a display device; and a control device. The control device includes: an engine control unit that controls the engine in such a manner that an actual idle speed of the engine in an idle state becomes a target idle speed that changes with a load of the auxiliary equipment on the engine; an acquisition unit that acquires the actual idle speed; a change determination unit that determines whether an accelerator operation amount is zero and the target idle speed is changing; a calculation unit that calculates a slowly changing idle speed obtained by smoothing the actual idle speed with a predetermined degree of smoothing when a determination of the change determination unit is affirmative; and a display control unit that displays the slowly changing idle speed on the display device.
