To detect desertion inside a vehicle with simple processing.SOLUTION: In an on-vehicle appliance 10, a control unit 13 estimates a quantity of passenger in a vehicle based on in-vehicle voice acquired before a driver of the vehicle gets off the vehicle, and estimates a quantity of passenger getting off the vehicle based on the in-vehicle voice acquired when the driver gets off the vehicle. Then, the control unit detects an occurrence of desertion of a living object in the vehicle based on the estimated quantity of passenger getting on the vehicle and the estimated quantity of passengers getting off the vehicle.SELECTED DRAWING: Figure 1
【課題】簡易な処理で車内置き去りを検出する。【解決手段】車載機10は、制御部13が、車両の運転者の降車前に取得した車内音声に基づいて車両の乗車数を推定し、運転者の降車時に取得した車内音声に基づいて車両の降車数を推定する。そして、推定した乗車数と推定した降車数とに基づいて車両内に生体物の置き去りが発生したことを検出する。【選択図】図1
