SEAT LOAD DETERMINATION DEVICE
First Claim
1. A seat load determination device, comprising:
- a load sensor provided at at least one of plural support portions supporting a seat for a vehicle, the load sensor mounted to the support portion provided at one of right hand side and left hand side at the seat among the plural support portions, the load sensor detecting a load applied to the support portion;
a lateral acceleration correlation information determination portion detecting an information value having a positive correlation with a lateral acceleration which corresponds to an acceleration in a vehicle width direction as a lateral acceleration correlation information value, and determining whether an absolute value of the lateral acceleration correlation information value is equal to or less than a predetermined value; and
a determination portion determining whether an adult passenger is seated in the seat or whether a child safety seat is fixed to the seat based on the load detected by the load sensor when the absolute value of the lateral acceleration correlation information value is equal to or less than the predetermined value.

Abstract
A seat load determination device includes a load sensor, which is provided at at least one of plural support portions supporting a seat, mounted to the support portion provided at one of right hand side and left hand side at the seat, and detecting a load applied to the support portion, a lateral acceleration correlation information determination portion detecting an information value having a positive correlation with a lateral acceleration which corresponds to an acceleration in a vehicle width direction as a lateral acceleration correlation information value, and determining whether an absolute value of the lateral acceleration correlation information value is equal to or less than a predetermined value, and a determination portion determining a seat load based on the load detected by the load sensor when the absolute value of the lateral acceleration correlation information value is equal to or less than the predetermined value.

10. A method for a seat load determination, comprising steps of:
-
detecting an information value having a positive correlation with lateral acceleration which corresponds to acceleration in a vehicle width direction as a lateral acceleration correlation information value; determining whether an absolute value of the lateral acceleration correlation information value is equal to or less than a predetermined value; and determining whether an adult passenger is seated in a seat or whether a child safety seat is fixed to the seat on the basis of a load detected by a load sensor, which is provided at at least one of plural support portions supporting the seat for a vehicle, mounted to the support portion provided at one of right hand side or left hand side at the seat among the plural support portions, and detects a load applied to the support portion, when the absolute value of the lateral acceleration correlation information value is equal to or less than the predetermined value.
