摘要： An improved occupant weight detection system (10) measures the pressure in a fluid-filled bladder (20) disposed in or under a foam seat cushion as an indication of occupant weight, and periodically adjusts the pressure vs. occupant weight relationship to compensate for changes due to aging and usage of the foam seat cushion (142, 102, 104). The system controller (50) develops an aging adjustment value based on a measure of the cumulative aging and usage of the seat (130, 132, 134, 136, 138), and uses the developed adjustment value to compensate the operation of the system (142, 102, 104). The aging adjustment value is determined primarily as a function of occupant weight and time of seat occupancy, and the compensation is achieved by using the aging adjustment value to adjust either the estimated weight, or a threshold to which the measured pressure is compared for purposes of deciding if restraint deployment should be enabled (142).

摘要翻译：改进的乘员体重检测系统（10）测量设置在泡沫座垫内或其下的流体填充的气囊（20）中的压力，作为乘员重量的指示，并且周期性地调节压力与乘员重量的关系以补偿变化由于泡沫座垫（142,102,104）的老化和使用。系统控制器（50）基于座椅（130,132,134,136,138）的累积老化和使用的量度来开发老化调整值，并且使用开发的调整值来补偿系统的操作（ 142,102,104）。老化调整值主要根据乘员体重和座位占用时间的函数确定，并且通过使用老化调整值来调整补偿，以调整估计的重量或测量压力的阈值，以将决定是否启用限制部署（142）。
