To accurately guide a vehicle to a parking area without being affected by an environment.SOLUTION: A parking guidance device which is mounted on a vehicle comprises: a reception processing section which receives transmission waves transmitted from a ground device installed at a fixed position on the ground through at least two on-vehicle receivers fixedly mounted on different locations of a vehicle; an estimation processing section which estimates the position of the ground device with reference to a position of a vehicle on the basis of a time difference between a first timing when the transmission waves are received by the reception processing section through at least a first on-vehicle receiver out of the two on-vehicle receivers and a second timing when the transmission waves are received by the reception processing section through at least a second on-vehicle receiver different from the first on-vehicle receiver out of the two on-vehicle receivers; and a guidance processing section which identifies a parking area relative to the ground device on the basis of the position of the ground device estimated by the estimation processing section and guides the vehicle toward the parking area.SELECTED DRAWING: Figure 2

    【課題】環境に左右されずに精度良く車両を駐車領域に誘導する。【解決手段】本開示の一例としての駐車誘導装置は、車両に設けられる駐車誘導装置であって、地上に固定的に設けられる地上装置から送信される送信波を、車両においてそれぞれ異なる位置に固定的に設けられる少なくとも2つの車上受波器を介して受信する受信処理部と、少なくとも2つの車上受波器のうちの第1の車上受波器を介して受信処理部により送信波が受信される第1のタイミングと、少なくとも2つの車上受波器のうちの第1の車上受波器とは異なる第2の車上受波器を介して受信処理部により送信波が受信される第2のタイミングと、の時間差に基づいて、車両の位置を基準とした地上装置の位置を推定する推定処理部と、推定処理部により推定される地上装置の位置に基づいて地上装置に対応するように設けられた駐車領域を特定し、当該駐車領域に向けて車両を誘導する誘導処理部と、を備える。【選択図】図2
