    • PROBLEM TO BE SOLVED: To provide an acceleration detector having improved accuracy for drift error correction.SOLUTION: An acceleration detector includes a vibration component removing part 20 that removes a vehicle vibration component included in a G sensor signal Gsen-f that has passed through a filter 13 at the moment of transitioning from a stopped state to a running state, and a zero-point correction part 21 that corrects a zero-point position of the G sensor signal Gsen-f that has passed through the filter 13 by using a correction value Gd based on a G sensor signal Gsen-r after the removal of the vehicle vibration component.
    • 要解决的问题:提供一种具有改进的漂移误差校正精度的加速度检测器。 解决方案:加速度检测器包括:振动成分除去部20,其除去在从停止状态转移到行驶状态时通过过滤器13的G传感器信号Gsen-f中包含的车辆振动成分 以及零点校正部21,其通过使用基于G传感器信号Gsen-r的校正值Gd来校正已经通过滤光器13的G传感器信号Gsen-f的零点位置 车辆振动分量。 版权所有(C)2012,JPO&INPIT
