Abstract
When it is confirmed that a user exists based on an image of the situation outside a vehicle which is captured using a camera and a proximity sensor detects a fact that the user is approaching based on, for example, a putting of a hand of the user over the proximity sensor, a control device causes a ramp to be extended. As such, a user sitting in a wheelchair can cause the ramp to be extended by approaching the proximity sensor, such as the putting of the user's hand over the proximity sensor such that the user sitting in the wheelchair does not have to press an extension/storage button provided on the vehicle to cause the ramp to be extended.
