Abstract
A ramp system includes: a ramp main body provided in a door opening and configured to be able to advance from a vehicle floor toward a road surface; a ramp-state detection device configured to detect an advancing-retracting state of the ramp main body; a display device configured to display an image in a display area observable from an operator seat; and a user interface (UI) controller configured to control display on the display device. The UI controller causes the display device to display a state image including an image indicative of the advancing-retracting state.
