In suspension design there exists a conflict of aims between vibration comfort and vehicle handling. Possibilities for improving conventional systems seem to be exhausted. As a result, new chassis concept, featuring the exclusive use of air springs has been presented. It enables ride height to be adjusted and spring/damper characteristics to be altered during the journey. The basic mode specifically provides optimum comfort. When driving conditions require it, stiffer spring/damper characteristics can be selected. Tests on the suspension indicate clear improvements in comfort, with further improvements likely once several weaknesses in the spring system have been ironed out. Problems associated with the automatic suspension control system are investigated, using calculations from simulations. It is evident that optimum results can be obtained only if the driver's handling of the vehicle is monitored.
