VEHICULAR OCCUPANT DETECTION DEVICE

WIPO Patent Application WO/2018/110365

A1

By detecting door closure, the present invention can update occupancy assessment results at an early stage when a vehicle has been entered or exited. A vehicular occupant detection device (8) that is characterized by comprising: a load sensor (11) that is attached at the periphery of a seat (2); and an occupant detection means (12) that detects an occupant on the basis of a detection value from the load sensor (11). The occupant detection means (12) is characterized by comprising an occupancy assessment unit (16) that assesses the seating state of the occupant, a vibration variation determination unit (17) that assesses whether there is vehicle vibration (17a), an occupancy determination unit (21) that determines whether to update or maintain occupancy assessment results, and a door closure determination unit (101) that examines a waveform for the detection value from the load sensor (11) and determines whether there has been a door closure on the basis of a load fluctuation pattern that indicates door closure, wherein, when the door closure determination unit (101) has determined that there has been a door closure, the vibration variation determination unit (17) determines that vehicle vibration (17a) occurred while the vehicle was stopped, and the occupancy determination unit (21) can update the occupancy assessment results.
