To detect a respiration frequency and a state other than the respiration frequency on an occupant.SOLUTION: An occupant state estimation system includes an on-vehicle device 10 and a belt side communication device 20 attached to a seat belt of a vehicle for communicating with the on-vehicle device 10. The belt side communication device 20 includes a belt position estimation part 151 for estimating a belt position where the belt side communication device 20 is attached based on a signal indicating reception signal intensity of a radio wave transmitted from the on-vehicle device 10. It further includes a respiration frequency estimation part 152 for estimating a respiration frequency per unit time of an occupant based on the belt position, and a seating position estimation part 153 for estimating a seating position of the occupant wearing the seat belt based on the belt position.SELECTED DRAWING: Figure 2
【課題】呼吸数とともに呼吸数以外の乗員の状態を検出できるようにする。【解決手段】車載器10と車両のシートベルトに取り付けられ車載器10と通信するベルト側通信機20を備える。ベルト側通信機20は、車載器10から送信された電波の受信信号強度を示す信号に基づいてベルト側通信機20が取り付けられたベルト位置を推定するベルト位置推定部151を備える。さらに、ベルト位置に基づいて乗員の単位時間当たりの呼吸数を推定する呼吸数推定部152と、ベルト位置に基づいてシートベルトを装着した乗員の着座位置を推定する着座位置推定部153を備える。【選択図】図2
