Occupant weight detecting device

摘要

An occupant weight detecting device includes a load detecting device and a control device. The load detecting device detects a load applied to a seat body. The control device detects an occupant sitting on the seat body based on a load detection value detected by the load detecting device. The occupant weight detecting device further includes a power supplying device for supplying power to the load detecting device and a memorizing device for memorizing the load detection value having been detected by the load detecting device. The control device performs primary filter calculation during a predetermined time based on the average of plural load detection values having been memorized to the memorizing device and a current load detection value. The control device performs secondary filter calculation after an elapse of the predetermined time based on one load detection value having been memorized to the memorizing device and the current load detection value.
