摘要： A seat load detection method includes a process in which a control unit records a transition of a load detection signal and a transition of a seat load, a process in which the control unit specifies a timing when a load sensor detects a collision of a vehicle based on a transition record of the load detection signal, and a process in which the control unit calculates a correction value of the seat load based on a difference value between a stable seat load provided after the control unit detects the collision of the vehicle and a stable seat load provided before the load sensor detects the collision of the vehicle.

摘要： A physique estimation device includes: a camera capturing an image of an inside of a vehicle; a skeleton point coordinate acquisition unit acquiring positions of skeleton points of a body image of an occupant included in a captured image of the inside as skeleton point coordinates in a two-dimensional coordinate system of the captured image; a front coordinate estimation unit machine learned such that, by receiving a distance between preset skeleton points and an angle of a skeleton line obtained by connecting the skeleton points with respect to a reference line, a front coordinate that is an arrangement of the skeleton points when the occupant is viewed from front is estimated and output; and a physique determination unit determining a physique of the occupant based on the front coordinate.

摘要： An indoor monitoring device includes: an image obtainment unit obtaining a captured image obtained by imaging an inside of a cabin of a vehicle by an imaging unit; and a position detection unit determining whether or not an occupant's head is present in the captured image, detecting a size of the head, a head position of the head, and a key point position of a key point other than the head of the occupant in the captured image in a case where the head is present in the captured image, and detecting a seating position of the occupant in the cabin based on the size of the head, the head position, and the key point position.

摘要： An occupant discrimination system of a vehicle seat includes: a load detecting portion disposed on a lower side of a seat and detecting a load acting on the seat; an occupant discrimination portion discriminating a state of an occupant among a no occupant, adult seated state, and child seat fixed states based on a load detected from the load detecting portion and a load continuation duration; and a door opening and closing detecting portion detecting an opening and closing state of a door, wherein the occupant discrimination portion changes the state transition condition from the no occupant or child seat fixed state to the adult seated state such that it is difficult to transition in a state in which the door is detected to be in an open state in comparison to a state in which the door is detected to be in a closed state.

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.
