Abstract
A road surface assessment apparatus for a vehicle includes an illumination device, a detector, and an assessment unit. The illumination device is configured to emit pattern light to a road surface on which the vehicle runs, or a surrounding of the vehicle. The detector is configured to detect the emitted pattern light. The assessment unit is configured to assess a condition of the road surface, on the basis of the detected pattern light. The illumination device intermittently emits the pattern light for a short time in such a manner that a period of time for which the pattern light is not emitted is longer than a period of time for which the pattern light is emitted.
