Abstract
An electric step control device for a vehicle having a step provided movably by power of a motor from a retraction position where the step is retracted under a vehicle body to an overhang position where the step appears from the vehicle body or vice versa according to an opening and closure operation of a door, has a control unit. The control unit executes an overhang drive control that moves the step from the retraction position to the overhang position according to an occurrence of the opening operation of the door having been at a closure position. And the control unit starts a retraction drive control that moves the step from the overhang position to the retraction position according to an occurrence of the closure operation of the door having been at a full open position at a predetermined timing before the door reaches the closure position.
