Roll Stabiliser Control Unit

Silver Atena has developed a precise control unit for an active central stabiliser. It improves the driving dynamics and so increases driving safety and
comfort. Rolling movements of the vehicles can be influenced through the active torsion springs and hence are virtually eliminated.

An innovative board technology allows for high integration density and easy adaption on varying power levels.

The precise control of the electromechanical actuator is the most important prerequisite for a high control quality. Only the accurate control ensures that the desired high dynamics are met even under elevated torque loads (e.g. during speedy cornering). The control unit not only offers optimised thermal management, it also has a well-engineered power-output stage. The high integration density means it can be accommodated in very confined spaces. Moreover, the control unit was developed under consideration of all safety-relevant aspects, which allow for certification according to ISO 26262 up to ASIL C.
