Abstract
A system for determining road quality includes a vehicle equipped with sensors to detect a position of the vehicle on the road and a suspension strut parameter indicative of road quality. The suspension strut parameter may be suspension strut pressure or suspension strut cylinder stroke. A threshold range is established outside of which an absolute value of the suspension strut parameter is associated with poor road quality. A computerized system generates a heat map to display relative quality of road segments.
