Riding comfort is a key issue when designing suspensions for commercial vehicles. It can be broadly defined as the degree of comfort of passengers during forward travel at cruise speed while exposed to road disturbances. Currently, this problem is addressed by suitable damping calibration, but even well-tuned suspensions perform badly beyond narrow speed ranges and regular road conditions. This paper proposes a novel control strategy for improving riding comfort in commercial vehicles, based on a semi-active system with heuristic properties. A case study is presented to validate the methodology, with overall good results. Copyright © 2009 Inderscience Enterprises Ltd.
