PROBLEM TO BE SOLVED: To provide an occupant detection device capable of correctly detecting presence/absence of an occupant even when a personal computer, a tablet, or a smartphone is mounted on a seat.SOLUTION: An occupant detection device 10 is mounted on a vehicle comprising: a vehicle body 12; a seat 13; and an on-vehicle power source 40. The occupant detection device comprises: an electrostatic sensor 11 which is provided in the seat and measures an electrostatic capacity between the seat and the vehicle body; an intercepting device 45 for intercepting a function of the on-vehicle power source; a control device 16 for temporarily actuating the intercepting device when a measured value measured by the electrostatic sensor is higher than a prescribed threshold; and a determination device 17 for determining that there is an occupant, when the measured value measured by the electrostatic sensor is still higher than the prescribed threshold when the intercepting device is actuated.SELECTED DRAWING: Figure 1
【課題】パソコン、タブレット、スマートフォン等をシート上に置いた状態でも、乗員の有無を正確に検知できる乗員検知装置を提供する。【解決手段】車両ボディ12と、シート13と、車載の電源40と、を備えた自動車、に設けられる乗員検知装置10であって、前記シート内に設けられ、前記車両ボディとの間の静電容量を測定する静電センサ11と、前記車載の電源の機能を遮断する遮断装置45と、前記静電センサの測定値が所定の閾値よりも高い場合に、一時的に前記遮断装置を作動させる制御装置16と、前記遮断装置が作動されている際の前記静電センサの測定値が依然として所定の閾値よりも高い場合に、乗員がいると判別する判別装置17と、を備えた乗員検知装置である。【選択図】図1
