LOAD OBJECT DETERMINATION APPARATUS

摘要

A load exerted on one of supporting parts supporting a seat of a vehicle is detected and is corrected according to an inclination of the vehicle. A load object on the seat is determined a plurality of times of turning on and turning off an ignition of the vehicle using the load thus corrected or the load detected. The load object is determined as an adult at least when the load is greater than or equal to a first threshold and determined as other than an adult at least when the load is less than a second threshold that is less than the first threshold. A function is further provided of determining the load object from a combination of a magnitude relation between the load and a third threshold less than or equal to the first threshold and greater than the second threshold and the inclination of the vehicle.

1. A load object determination apparatus comprising:
a load detection part installed at a supporting part at either one of two opposite sides among a plurality of the supporting parts that support a seat of a vehicle, the load detection part detecting a load exerted on the supporting part; a load correction part that corrects the load detected by the load detection part according to each of inclinations of the vehicle in the two opposite sides; an inclination detection part that detects a physical quantity corresponding to each of the inclinations of the vehicle in the two opposite sides; a determination part that at least determines whether a load object on the seat is an adult or other than an adult including a lashed child seat a plurality of times of a predetermined timing during a period of time from turning on an ignition of the vehicle to turning off the ignition using a corrected load as a load for determination when the load corrected by the load correction part is available and using the load detected by the load detection part as the load for determination when the load corrected by the load correction part is not available, and determines that the load object on the seat is an adult at least when the load for determination is greater than or equal to a first threshold and determines that the load object on the seat is other than an adult at least when the load for determination is less than a second threshold that is set to be less than the first threshold, wherein the determination part further has a function of determining whether the load object on the seat is an adult or other than an adult according to a combination of a magnitude relation between the load for determination and a third threshold that is set to be less than or equal to the first threshold and greater than the second threshold and the physical quantity detected by the inclination detection part.
