Problem to be solved: to provide a technique for improving the judgment accuracy of a physical abnormality of a driver while driving a vehicle.In the detecting device 1, the head motion acquisition section 60 acquires the movement of the head of the vehicle driver. The vehicle motion acquisition part 61 acquires the movement of the vehicle. The correlation calculating section 62 calculates a correlation between the movement of the head and the movement of the vehicle. The output section 63 outputs a signal indicating that the correlation is less than a predetermined threshold value.The detecting apparatus 1 may further include a shake width calculating section 64 for calculating a statistical quantity relating to a fluctuation width of the movement of the vehicle, and a threshold setting section 65 for setting the threshold value lower as the shake width is larger.Diagram【課題】車両を運転中の運転者の体調異常の判定精度を向上する技術を提供する。【解決手段】検出装置1において、頭部動き取得部60は、車両の運転者の頭部の動きを取得する。車両動き取得部61は、車両の動きを取得する。相関算出部62は、頭部の動きと車両の動きとの相関を算出する。出力部63は、相関が所定の閾値を下回ったことを示す信号を出力する。検出装置1は、記車両の動きの振れ幅に関する統計量を算出する振れ幅算出部64と、振れ幅が大きいほど、閾値を低く設定する閾値設定部65とをさらに備えてもよい。【選択図】図2
