Description

Authors have applied the skyhook control that does the controlled variable proportional to the road displacement in feed-forward to the electric preview active stabilizer suspension system that is called eActive2 so far, and have verified the performance. Moreover, authors examine the preview control that is the means to make amends for the response delay of actuator by calculating the controlled variable based on road information forward, and have verified the effectiveness. Authors applied the preview control verified with eActive2 to eActive3, which became possible to control three modes by having made actuator in the rear of eActive2 become independent, and verified the ride comfort performance. As a result, the ride comfort performance of the roll direction achieved the effect of equal eActive2. In addition, vibration transmissibility to the body in rear and Rear load-deflection have been improved. The ride comfort performance of the in case for the road displacement to control the preview with eActiveS was verified.
