PROBLEM TO BE SOLVED: To suppress a reduction in accuracy of biological information due to noise of a vehicle.SOLUTION: A biological information acquisition device includes: a first body motion detection section (38) having a first pressure-sensitive part (35) on which body motion of a living body (1) in a vehicle (10) acts and outputting a first signal corresponding to the body motion acting on the first pressure-sensitive part (35) a second body motion detection section (48) having a second pressure-sensitive part (45) on which the body motion of the living body (1) in the vehicle (10) acts and outputting a second signal corresponding to the body motion acting on the second pressure-sensitive part (45) an adaptive filter (57) for processing the second signal so as to reduce an error signal being a difference between the first signal and the second signal after adaptively processing and a biological information acquisition section (60) for obtaining biological information of the living body (1) on the basis of the error signal.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2018,JPO&INPIT【課題】車両のノイズに起因して生体情報の精度が低下してしまうことを抑制する。【解決手段】生体情報取得装置には、車両(10)上の生体(1)の体動が作用する第1感圧部(35)を有し、第1感圧部(35)に作用する体動に応じた第1信号を出力する第1体動検出部(38)と、車両(10)上の生体(1)の体動が作用する第2感圧部(45)を有し、第2感圧部(45)に作用する体動に応じた第2信号を出力する第2体動検出部(48)と、第1信号と、適応処理後の第2信号との差分である誤差信号が小さくなるように、該第2信号を処理する適応フィルタ(57)と、誤差信号に基づいて生体(1)の生体情報を求める生体情報取得部(60)とが設けられる。【選択図】図1
