A storage maintains coefficients that map histogram data elements to tire wear, the coefficients being trained based on a correlation of histogram data to measured tire wear. A processor is programmed to receive a wear data histogram from a vehicle, utilize the coefficients to translate the wear data histogram into a measure of physical tire wear; and send an alert message indicating the estimated tire wear.

A device for measuring a tire ground state includes a traveling surface, a tire drive unit grounding a tire on the traveling surface and rolls the tire, a measuring sheet mounted to a partial area of the traveling surface for measuring the tire ground state, a protection sheet covering the measuring sheet, and a backward and forward tensile force application mechanism applying a tensile force along a tire forward traveling direction to the protection sheet. A space conducting the protection sheet to a portion below the traveling surface is formed in at least one of a delay side and an advance side of the measuring sheet in the tire forward traveling direction on the traveling surface, and the backward and forward tensile force application mechanism is structured such as to pull at least one end of the protection sheet in the tire forward traveling direction from below the traveling surface.

In the present invention, virtual regions each having a width of 1/2n (where n is a natural number greater than or equal to 1) of the detection width of a force sensor provided on a tire travel surface are set in a region to be measured of a tire. The contact position between the tire travel surface and tire is shifted along a prescribed direction such that the force sensor touches a single virtual region a plurality of times, and the sensor is used to carry out force measurement a plurality of times. Mapping data is generated that associates each measurement time with data about the positional relationship between the virtual regions and sensor. Force values for each virtual region are calculated on the basis of the sensor detection values and the force balance relationship between the sensor and virtual regions determined by a mapping data generation unit.

An object surface managing method comprising: (a) emitting detecting light to the groove via alight source; (b) receiving first reflected detecting light from the surface and second reflected detecting light from a bottom of the groove via a light sensor; and (c) calculating a groove depth of the groove according to the first reflected detecting light and the second reflected detecting light.
