Description
まず、サンプリングデータ判別処理及びGデータ判別処理の詳細説明に入る前に、その前提として、本実施形態におけるGデータの判別原理について説明する。
上記のような、図8中のTA期間、TB期間、TC期間、TD期間に該当するステップS22〜S32の実行後、CPU47は、エラーデータを「0」にリセットし(ステップS33)、さらに、タイマ42の受信周期カウンタをリセットしてステップS46の処理に移行する(ステップS34)。
G=D1+D2+D3+D4=Gave ・・・・(1)
G=4×{(D1+D2+D3)/3}
=4×Gave/3 ・・・・(2)
(1)上記実施形態では、PCS10から送信されるシリアルデータに、80ms周期で通信されるLoGデータと、250μs周期で連続通信されるHiGデータとが含まれている場合を想定して説明したが、これらの周期はあくまで一例であり、本発明はこれ以外の周期でLoGデータ及びHiGデータが送信される場合にも適用することができる。
Claims (3)
- 第1周期で受信した加速度データを低加速度データと判別し、前記第1周期より短い第2周期で受信した加速度データを高加速度データと判別する電子制御装置であって、
処理単位時間内に取得した受信データ中に、前記低加速度データと判別可能な加速度データと、前記高加速度データと判別可能な加速度データとが混在する場合、前記低加速度データと判別可能な加速度データを破棄するデータ処理部を備え、
前記データ処理部は、前記処理単位時間内に取得した受信データから前記低加速度データと判別可能な加速度データを破棄した後、残った加速度データを前記高加速度データとして用いることを特徴とする電子制御装置。 - 前記データ処理部は、前記処理単位時間内に取得した受信データ中に、前記低加速度データと判別可能な加速度データのみが存在する場合、当該加速度データを前記低加速度データとして用いることを特徴とする請求項1記載の電子制御装置。
- 前記データ処理部は、前記処理単位時間内に取得した受信データ中に、前記高加速度データと判別可能な加速度データのみが存在する場合、当該加速度データを前記高加速度データとして用いることを特徴とする請求項1または2に記載の電子制御装置。
