Abstract: To provide a belt-shaped fabric for hose and a hose capable of achieving an improvement in terms of workability during hose production. When spirally winding a belt-shaped fabric 14 for covering around the outer periphery of an inner tube rubber 12, and covering the outer side thereof with wire 16 and rubber 18, at least a portion of the fiber forming the belt-shaped fabric 14 is covered with rubber cement 24, whereby weave deviation is not easily generated even when the belt-shaped fabric 14 is spirally wound for covering around the outer periphery of the inner tube rubber 12. In the case where the fiber of the belt-shaped fabric 14 is impregnated with a dip liquid, the dip liquid is not easily exposed to the oxygen in the air, so that it is possible to suppress deterioration of the dip liquid.

Abstract: In a method for determining a road surface condition, the speed of calculation is improved by applying an appropriate path limitation. To further improve the accuracy of determination, a time-series waveform of tire vibration detected by an acceleration sensor is windowed at time width T by a windowing means, and time-series waveforms of tire vibration in the respective time windows are extracted before feature vectors Xi of the respective time windows are calculated. Then kernel functions KA (X, Y) are calculated from the feature vectors Xi for the respective time windows and road surface feature vectors Yi, which are feature vectors for the respective time windows calculated from time-series waveforms of tire vibration having been determined in advance for distinctive road surface conditions.
