Abstract
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.
