Vehicle height adjusting device

A vehicle height adjusting device comprising:

• a vehicle height adjusting unit configured to set a vehicle height to a first state or a second state, the first state being a state in which a tire of a vehicle is suspended at a predetermined position with respect to a vehicle body in a vehicle up-down direction, and the second state being a state in which the tire is suspended at a position closer to the vehicle body in the vehicle up-down direction than in the first state;
• a prediction unit that predicts whether a lower portion of the vehicle interferes with a road surface in the second state;
• and
• a vehicle height control unit that controls the vehicle height adjusting unit such that the vehicle height adjusting unit sets the vehicle height to one of the first state and the second state, and that restricts a transition from the first state to the second state by the vehicle height adjusting unit when the prediction unit predicts an interference between the lower portion of the vehicle and the road surface.
