Abstract
An apparatus of for measuring roughness of a road surface such as convex, concave or inclination is to be mounted on the vehicle. The apparatus comprises a rotation driving member for generating rotation motion in vertical plane and for outputting a signal concerning its rotation angle. An inclinometer is provided to detect an inclined angle of the rotation driving member. A distance measuring member for measuring distance from road surface as being rotated by the rotation motion from said rotation driving member. A processing unit calculates a vertical distance and a horizontal distance between the apparatus and the road surface by means of the inclined angle detected by the inclinometer and the rotation angle detected by the rotation driving member.
