Abstract
【解決手段】生体情報検出装置10は、車両開放検出部1aと、乗り込み検出部1bと、電波送受信部2と、生体情報検出部3と、補正値設定部32とを備えている。車両開放検出部1aによる車両50の開放の検出後で、かつ、乗り込み検出部1bによる運転手Dの車両50への乗り込みの検出前に、電波送受信部2により電波を送信してその反射波を受信し、該受信結果に基づいて生体情報を検出するための補正値Io、Qoを補正値設定部32により設定する。そして、乗り込み検出部1bによる運転手Dの車両50への乗り込みの検出後に、電波送受信部2により電波を送信して、運転手Dの体表面Daで反射した反射波を受信し、該受信結果と補正値Io、Qoとに基づいて、生体情報検出部3により運転手Dの生体情報を検出する。
