Proposal of Data-Based Preview Controller for Active Vehicle Suspension

Abstract

This paper proposes the new concept of preview controller for active vehicle suspension. This preview controller generates an unsprung mass state value map using data obtained from a positioning system, accelerometer, and the like. It then realizes control using the generated map and positioning system. The accuracy of unsprung mass displacement estimation and the advantage compared to feed-back control and preview control with data processed online were validated in equations, simulations, bench tests, and on-road tests.
