Adaptive air suspension is an electronically controlled air suspension system at all four wheels with a continuously adaptive damping system.
It combines sporty handling with a high level of ride comfort.
Additionally, the air suspension allows the speed-dependent lowering of the body – this change in ride height means a low center of gravity and significantly increased directional stability as a result. The vehicle’s handling characteristics are improved at the same time. Some European vehicles have air suspension struts at all four wheels.
The information obtained from sensors on the axles and acceleration sensors on the body is evaluated in the adaptive air suspension's central control unit. This computer can control the adjustment of the individual shock absorbers in milliseconds, depending on driving situation.
Provided no higher damping forces are required – for instance when driving straight ahead on good roads – the damper settings remain comfortably soft.
Specific adjustments to the damping force at individual wheels eliminates body movement, which could affect occupant comfort.
When cornering, braking or moving away, adaptive damping can, in some instances, automatically reduce rolling or pitching movements.
Adaptive air suspension also offers the advantages of:
