Suspension systems have a major effect on the handling characteristics of a vehicle, particularly ride comfort and handling safety, and thus substantially determine its character. Their increasing significance is reflected by the greater value that ever more demanding customers attribute to the properties ride comfort and handling safety. Now that the potential of conventional, passive systems is largely exhausted, adaptive and active systems open up new possibilities, e.g.: the suppression of rolling and pitching movements, handling and ride height independent of load, handling characteristics and ride height adaptable to situation and customer requirement. The DaimlerChrysler active suspension and damping system (Active Body Control – ABC) manages to resolve the conflict of aims between handling safety and ride comfort which afflicts conventional fixed suspension systems, and as a result offers greater freedom of layout whilst enabling optimization of both target criteria.
