Abstract

The present invention has an object to provide a vehicle control device which does not require a complicated operation to start an engine even if an idle-stop function has been executed. Thus, the present invention includes a mechanical automatic transmission, an idle-stop device ( 1 ) for stopping the engine when the vehicle is stopped, a slope detection device ( 2 ) for detecting a slope of a road, and a control unit ( 10 ), and is characterized in that the control unit ( 10 ) has a function for disengaging a clutch and selecting a gear appropriate for the detected slope, when the slope detected by the slope detection device ( 2 ) is at or above a threshold value and an operation of the idle-stop device ( 1 ) has been requested.
