The paper deals with the investigation of limited-active nonlinear suspension control in order to stabilize the lateral vehicle motion in similar way as systems like ESP do. The lateral stabilization of vehicle based on braking forces can be alternatively provided by the different setting of suspension forces. The basis of this control is the nonlinear properties of the tyres. The vehicle has at least four wheels and it gives one or more redundant vertical forces that can be used for the different distribution of vertical suspension forces in such a way that resulting lateral and/or longitudinal forces create the required correction moment for lateral dynamic vehicle stabilization. This has been already studied by semi-active suspension control and proposed for fully-active suspension control. The novelty of this study is the investigation of such lateral dynamic vehicle stabilization using fully active and limited-active suspension control and the investigation of the energy requirements of such control. The clear dependency was found between the corrective torque of the vehicle and the tire vertical forces redistribution among four corners of the vehicle. The results give to the dynamic body control system the opportunity to control the lateral dynamics of the vehicle. The limitation of the system is caused by the contact of the tire. The maximal force dN should be less then tire static load force.
