Title:
【発明の名称】加速度センサの誤差を補償する方法
Document Type and Number:
Japanese Patent JPH0778506
Kind Code:
B2
Abstract:
A process for compensating systematic errors of an acceleration sensor. The result of a sliding average of the output of the accelerometer, determined when acceleration in the primary measurement direction is zero, is subtracted from the output of the accelerometer thus producing a signal representative of acceleration only in the primary direction. A functional check of the accelerometer is provided by aligning the accelerometer in a second direction and comparing the acceleration measured in this second direction to the acceleration measured in the primary direction by a second device for determining acceleration and indicating a malfunction when the two measured accelerations are different and it is determined that acceleration only in the primary direction is present.
