    摘要: An occupant detection method includes detecting a load applied to a seat for a vehicle, determining whether or not an occupant is seated at the seat, calculating a load deviation value indicating deviation of the load, determining whether or not the deviation exists at the seat on the basis of the load deviation value, and estimating that a seating posture of the occupant is inclined in a direction in which the load is deviated in a case where it is determined that the deviation exists and that a stable state is established, the stable state corresponding to a state in which a difference between a first change amount in a first cycle and a second change amount in a second cycle is within a predetermined range.

    摘要: A seat passenger determination apparatus includes: a first determination processing unit configured to determine a passenger is not seated on a vehicle seat by having gotten out of the vehicle and transfer the mode to a not-seated recognition mode when a load variation width detected by a load detection apparatus falls within a first threshold value in a state in which a non-fastened state of a seatbelt is detected; and a second determination processing unit configured to determine the passenger is not seated on the vehicle seat by having gotten out of the vehicle and transfer the mode to the not-seated recognition mode when the load variation width detected by the load detection apparatus falls within a second threshold value which is larger than the first threshold value during a predetermined time when the fact that the seatbelt has changed from the fastened state to the non-fastened state is detected.

    摘要: A seating determination apparatus includes a transition processing unit 29 configured to make a transition of the state between a first seating determination state in which an airbag apparatus is brought into an operation-permitted state and the second seating determination state in which the airbag apparatus is in the operation-prohibited state when a transition condition on the basis of a magnitude relationship between a seat load and a preset threshold value is satisfied, and configured to prohibit the transition of the state between the first seating determination state and the second eating determination state when the direction of variation of the seat load is determined to have inverted before a predetermined time set in advance has elapsed from a time point when the transition condition is satisfied.

    摘要: In a seatbelt warning apparatus, a control unit performs a transition process configured to transfer the mode to a baggage recognition mode on the condition that a load detection unit detects a load larger than a first load and smaller than a second load continuously for a preset time in the not-seated recognition mode, and to the not-seated recognition mode on the condition that the load detection unit detects a load smaller than a predetermined load continuously for a preset time in the baggage recognition mode, and a transfer time t1 required to transferring to the baggage recognition mode in the transition process is set to be shorter than a time T required for increasing the load from the first load to the second load by the vehicle acceleration characteristics.
