To highly accurately determine a type and a state of a person existing in a cabin of a vehicle.SOLUTION: A living body detection device comprises: a sensor which transmits a laser beam whose frequency is modulated to a cabin of a vehicle as a transmission wave and receives a reflection wave generated by a reflection of the transmission wave by an object in the cabin; a first generation unit which generates three-dimensional map information in the cabin on the basis of intensity distribution of the reflection wave; a second generation unit which generates speed information about a speed of the object in the cabin on the basis of Doppler shift of the reflection wave; a first detection unit which detects a child in the cabin on the basis of the three-dimensional map information and the speed information; a second detection unit which detects a position of a seat in the cabin; and a determination unit which determines whether or not the child is seated on a child seat on the basis of a position of the child detected by the first detection unit and the position of the seat detected by the second detection unit.SELECTED DRAWING: Figure 2

    【課題】車両の室内に存在する人物の種別や状態を高精度で判別する。【解決手段】生体検知装置は、車両の室内に周波数変調されたレーザ光を送信波として送信し、送信波が室内の物体により反射されることにより発生する反射波を受信するセンサと、反射波の強度分布に基づいて室内の三次元マップ情報を生成する第1生成部と、反射波のドップラシフトに基づいて室内の物体の速度に関する速度情報を生成する第2生成部と、三次元マップ情報と速度情報とに基づいて室内の子供を検知する第1検知部と、室内のシートの位置を検知する第2検知部と、第1検知部により検知された子供の位置と第2検知部により検知されたシートの位置とに基づいて、子供がチャイルドシートに着座しているか否かを判定する判定部と、を備える。【選択図】図2
