Study of Preview Ride Comfort Control for Electric Active Suspension (eActive3)

電動アクティブサスペンション(eActive3)におけるプレビュー乗り心地制御の検討

The electric active suspension system, named eActive3, is equipped with three electric rotary type actuators. This system can control three modes of the vehicle. Authors propose two logics of preview control in the rear suspensions. One of the logics is feed-forward skyhook control by the estimated road displacement of the single suspension. The other is feed-forward skyhook control by the estimated laterality and antero-posterior gradient of the road surface. In addition, the test result of ride comfort performance and consumption energy is experimentally verified.乗り心地性能向上システムとして，ロータリ式電動アクチュエータを3個搭載し，車両3モードを制御可能としたプレビューアクティブサスペンションシステムeActive3を開発した．本稿では，ロールとピッチの乗り心地性能の両立を目的とし，リア輪の制御則として，前方路面変位の左右差と前後差に着目したFFスカイフック制御ロジックを提案し，乗り心地性能及び消費エネルギ性能等を検証したので，その結果について報告する．
