Abstract

This paper presents the development of the road-sensing system and its application to active suspension system using preview road information. The road-sensing system which can robustly reconstruct the road input profiles from the intermixed data with the vehicle's dynamic motion, is implemented using the composite-sensor system with the optimally shaped transfer function. The performance of this system is evaluated by a series of experimental works in the devised moving-road type simulator. And a real car test equipped with the road-sensing system is performed in the proving ground over both deterministic and random road surfaces. Finally, a controller with preview control scheme based on the 7 degrees of freedom full vehicle model is designed in the frame work of active suspension system, the control performance is evaluated by simulation using the real test road profile data through the road-sensing system.
