When the road is bad, can't even the best chassis do anything? The active roll stabilization of the ACTIVE CURVE SYSTEM from Mercedes-Benz significantly optimizes driving comfort. When cornering, the stabilizers are actively influenced and keep the torsional moment constant. The rolling moment is distributed variably and the vehicle is adapted to every situation. The driver experiences the feeling of being on rails - especially in vehicles with a high center of gravity. In off-road use, the system ensures better axle articulation by decoupling the two stabilizers on the front and rear axles.
The ACTIVE CURVE SYSTEM compensates for the body roll angle when cornering, thereby increasing agility and driving pleasure significantly. At the same time, the system increases driving stability and thus safety, especially at higher speeds. The advantages of the ACTIVE CURVE SYSTEM are also among the advantages of the ACTIVE CURVE SYSTEM.
When driving straight ahead, there is an improvement in comfort, because here the turntables decouple the two anti-roll bar halves on the front and rear axles, so the anti-roll bars are open and do not react to one-sided stimulation from potholes or bumps.
Increased driving comfort and driving dynamics when cornering, because the torsional moments and angles of rotation of the stabilizers are actively influenced. In addition, the torsional moment of the stabilizers remains constant even with unilateral excitation, for example when driving through a pothole on the outside of the curve. The different controls on the front and rear axles distribute the rolling moment variably, thereby actively adapting the self-steering behavior to the respective driving situation. The driving behavior is particularly agile when driving on country roads, and particularly stable when driving on the motorway. In the interests of greater driving dynamics, the rear axle stabilizer on the ML 63 AMG is larger.
The essential components of active roll stabilization include a belt-driven hydraulic pump and an oil tank in the engine compartment as well as a valve block and active stabilizers on the front and rear axles. Compared to a passive stabilizer, the active stabilizers are divided in the middle and connected to one another via hydraulic rotary actuators. Pressure sensors and a lateral acceleration sensor inform the electronic control unit for regulating the hydraulic pressure via CAN signals.
