EU-Project COPERNICUS: Development of Semi-Active Road-Friendly Truck Suspension: Choice of Control Law, Experimental Verification, Implementation, Results

This is the second part of the paper describing the EU-funded COPERNICUS Project SADTS "Semi-Active Damping on Truck Suspension and its Influence of Drivers and Road Loads". This part deals with the description of considered control concepts, choice of suitable control law, its implementation, experimental verification and achieved results. The main results is that the current technology of semi-active truck suspension enables to reduce the dynamic road-tyre forces by about 10 % and this potential can be used either for reduction of road damage or for increase of allowed payload transported by trucks. Finally the open question for future development are mentioned: what must be developed and tested, how to improve present results, how to apply the achieved results etc.
