| Abstract(J) | 路面状態を把握する手段は，カメラやLiDAR、ミリ波レーダといった光や電波のほか，タイヤとの相互作用で発生する機械的な振動や電気的な変化を利用した方式が提案されている．走行時の車両に生じる準静電界と呼ばれる電位変動が，路面の電気特性に起因することに着目した新たなセンシング方式を中心に紹介する． Translation |
| Abstract(E) | In addition to optical and radio wave methods such as cameras, LiDAR, and millimeter-wave radar, methods that use mechanical vibrations and electrical changes caused by the interaction with the tires have been proposed to detect road surface conditions. This paper introduce a new sensing method that focuses on the fact that the potential fluctuation, called quasi-electrostatic field, generated in a vehicle during driving is caused by the electrical characteristics of the road surface. |
