Active suspension system from the lateral dynamics point of view

Abstract eng:
This paper presents the investigation of active suspension control with the obejctive to stabilize the lateral vehicle motion in similar way like ESP does. The vehicle with at least four wheels gives one or more redundant vertical forces. This effect can be used for the different distribution of vertical suspension forces in such a way that resulting lateral and longitudinal forces create the required correction torque for vehicle lateral dynamics stabilization. The amount of the generated stabilization torque was measured and compared to a passive vehicle using the so-called β − method, which is based on the evaluation of the vehicle steadystate cornering. Proposed stabilisation control algorithm was verified on dynamic avoidance manoeuvres.
