Abstract
Description
プロセッサコア110の作動を、図4のフローチャートに沿って説明する。プロセッサコア110は、車両のイグニッションスイッチがオンの状態において、定期処理に相当する図4の処理をS101から順に周期的に実行する。図4の実行周期は、定期処理の間の待機期間を、六つのセンサ部12の取り込み処理の完了に要する時間よりも長くするように設定されている。
以上、説明した実施形態によれば、カウンタ部112により、取り込み処理の完了回数がカウントされている。カウンタ部112によりカウントされた完了回数は、要求部111により要求された取り込み処理が完了しなかった場合、要求回数と対応しない回数となる。故に取込異常判断部113は、要求部111による取り込み処理の要求回数とカウンタ部112のカウントした完了回数との比較により、未完了異常の発生の有無を判断しうる。従って、シフトバイワイヤ制御装置100は、取り込み処理の未完了異常を検出可能である。
以上、本開示の実施形態を説明したが、本開示は上述の実施形態に限定されるものではなく、次の変形例も本開示の技術的範囲に含まれ、さらに、下記以外にも要旨を逸脱しない範囲内で種々変更して実施できる。なお、以下の説明において、それまでに使用した符号と同一番号の符号を有する要素は、特に言及する場合を除き、それ以前の実施形態における同一符号の要素と同一である。また、構成の一部のみを説明している場合、構成の他の部分については先に説明した実施形態を適用できる。
