Seat occupancy determination device and seat occupancy determination method
First Claim
1. A seat occupancy determination device configured to be provided at one of seating portions of a plurality of vehicle seats of a vehicle, the plurality of vehicle seats mounted to the vehicle to be placed next to each other in a right-left direction, the plurality of vehicle seats in which a passenger is seated to face a front or a rear of the vehicle, comprising:
- a pair of seat occupancy amount detection devices configured to be provided at a front portion and a rear portion of one of a right side and a left side of the vehicle seat, the pair of seat occupancy amount detection devices detecting a seat occupancy amount increasing and decreasing in response to a change of a load applied to each portion of the seating portion;
a seat occupancy threshold value setting device setting a seat occupancy threshold value which corresponds to a threshold value of the seat occupancy amount;
a seat occupancy state determination device determining a seat occupancy state of the vehicle seat by comparing a seat occupancy calculation amount calculated based on a detected signal transmitted from the pair of seat occupancy amount detection devices with the seat occupancy threshold value; and
an unbalanced load detection device detecting a degree of unbalance of the load applied to a right portion and a left portion of the seating portion in response to an inclination angle of the vehicle in the right-left direction;
whereinthe seat occupancy threshold value setting device corrects the seat occupancy threshold value in response to the degree of unbalance of the load applied to the right portion and the left portion of the seating portion based on a detected signal transmitted from the unbalanced load detection device.

7. A seat occupancy determination method using a pair of seat occupancy amount detection devices configured to be provided at a front portion and a rear portion of one of a right side and a left side of one of seating portions of a plurality of vehicle seats of a vehicle, the plurality of vehicle seats mounted to the vehicle to be placed next to each other in a right-left direction, the plurality of vehicle seats in which a passenger is seated to face a front or a rear of the vehicle, comprising processes of:
-
detecting a seat occupancy amount increasing and decreasing in response to a change of a load applied to each portion of the seating portion by the pair of seat occupancy amount detection devices; comparing a seat occupancy calculation amount calculated based on a detected signal transmitted from the pair of seat occupancy amount detection devices with a seat occupancy threshold value which corresponds to a threshold value of the seat occupancy amount to determine a seat occupancy state of the vehicle seat; detecting a degree of unbalance of the load applied to a right portion and a left portion of the seating portion in response to an inclination angle of the vehicle in the right-left direction; and correcting the seat occupancy threshold value in response to the degree of unbalance of the load applied to the right portion and the left portion of the seating portion.
