Active Roll Stabilization, Basic Function - GF32.34-P-1000A

Model all (CAR) 

with code 465 (Electric Active Roll Stabilization (EARS)) 

General 

Active Roll Stabilization is achieved by chassis systems that actively influence the rolling motion of the vehicle body.

Whereas passive systems, such as stabilizers or torsion bars on the front and rear axles, (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).

So as to actively counteract the vehicle body's rolling motions and ensure an increase in driving dynamics, ride comfort and driving safety, the following systems are used:
