    • Body velocity estimating device 10A is constituted by acceleration measurement unit 11, acceleration separation unit 12, filter processing operation unit 13, acceleration addition unit 14, integration processing operation unit 15, and estimated body velocity output unit 16. The unit 12 compares an acceleration measured by the unit 11 with set acceleration upper and lower limit reference values to separate the measured acceleration into reference value range-in and range-out accelerations. The unit 13 performs filtering on the separated reference value range-out acceleration to calculate filtered accelerations of the reference value range-out acceleration. The unit 14 adds the filtered accelerations to the previously separated range-in acceleration. The unit 15 multiplies the added acceleration by an operation period, and adds the resultant to the estimated body velocity calculated in the preceding one operation period to update the value of the estimated body velocity. The unit 16 outputs the updated estimated body velocity.
    • 车身速度估计装置10A由加速度测量单元11,加速度分离单元12,滤波处理运算单元13,加速度加法单元14,积分处理运算单元15以及估计体速输出单元16构成。单元12比较测量的加速度 由单元11设置加速度上限和下限参考值,以将测得的加速度分为参考值范围和范围外的加速度。 单元13对分离的基准值范围外加速度进行滤波,以计算基准值范围外加速度的滤波加速度。 单元14将过滤的加速度加到先前分离的加速度范围内。 单元15将添加的加速度乘以操作周期,并将结果相加到在前一个操作周期中计算的估计体速度,以更新估计体速的值。 单元16输出更新的估计身体速度。
