To provide a seat heater control device which can realize seating determination based on a thermal image by a thermo camera with a simple configuration while dealing with a difference in seat position.SOLUTION: A seat heater control device comprises: a first acquisition unit which acquires reference heat distribution information at a seat position that approximates to an actual seat position from a table when detecting the presence/absence of seating of an occupant in a seat by comparing reference heat distribution information obtained by referring to the table in which the reference heat distribution information and the seat position are associated with each other with information on a thermal image including a heating region by a seat heater imaged by a thermo camera; and a second acquisition unit which obtains the reference heat distribution information at the actual seat position by performing interpolation processing based on the reference heat distribution information stored correspondingly to a plurality of seat positions that approximate to the actual seat position from the table. The device selects any one of the first acquisition unit and the second acquisition unit according to a condition for seating detection.SELECTED DRAWING: Figure 11

    【課題】サーモカメラの熱画像に基づく着座判定を、シートポジションの違いに対処しつつ簡易な構成で実現できる、シートヒータ制御装置を提供する。【解決手段】本発明に係るシートヒータ制御装置は、基準熱分布情報とシートポジションとを対応付けたテーブルを参照して求めた基準熱分布情報と、サーモカメラが撮影したシートヒータによる加温領域を含む熱画像の情報とを比較して、シートにおける乗員の着座の有無を検出する場合に、テーブルから実際のシートポジションに近似するシートポジションでの基準熱分布情報を取得する第1取得部と、テーブルから実際のシートポジションに近似する複数のシートポジションに対応して保存されている基準熱分布情報に基づく補間処理を行って、実際のシートポジションでの基準熱分布情報を求める第2取得部とを有し、着座検出の条件に応じていずれか一方を選択する。【選択図】図11
