摘要：Provided is a velocity calculating device including a vertical accelerationdetector mounted on a moving body that travels on a predetermined travel surface, thevertical acceleration detector detecting an acceleration in a vertical direction generated

due to an undulation of the travel surface; a horizontal angular velocity detectormounted on the moving body, the horizontal angular velocity detector detecting anangular velocity around a horizontal axis that is perpendicular to a direction of travel ofthe moving body, the angular velocity being generated due to the undulation of thetravel surface; a velocity calculator that calculates a velocity of the moving body in thedirection of travel of the moving body on the basis of the acceleration in the verticaldirection and the angular velocity around the horizontal axis; and a velocity corrector thatcorrects the velocity in accordance with the velocity.
