Vibration and motion control of vehicle by active suspension and steering systems.

Abstract

Adaptation of active control to car chassis is expected to improve the ride comfort quality, vehicle controllability and stability. In this study, the experimental vehicle is equipped with a front active steering system and independent hydropneumatic suspension systems, which are integrated control elements and power sources. The performance is examined by running tests, in which the riding-comfort characteristics are fairly improved and the effects of both steering and suspension controls are confirmed to induce the stable controllability and stability of the vehicle.
