General
Active Roll Stabilization is achieved by chassis systems that actively influence the rolling motion of the vehicle body.
Function
In contrast to passive systems such as stabilizers or torsion bars at the front and rear axles that (statically) increase the rolling strength of the suspension, in Active Roll Stabilization, applied forces are counteracted depending on the situation.
Rolling motions should always be differentiated between driver-induced and roadway-induced rolling. Driver-induced rolling is caused by steering motions which can be felt as transverse forces (yaw, rolling) on the vehicle body. Roadway-induced rolling occurs when driving over uneven roads, e.g. when driving over obstacles on one side that involve lifting and angular movements on the crossbeam or longitudinal axis (pitching/rolling).
In order to actively counteract the vehicle body's rolling motions and ensure an increase in vehicle dynamics, ride comfort and driving safety, the following systems are used:
- Electric Active Roll Stabilization (EARS)
- Semi-active roll stabilization (Semi ARS)
