General
The damping mode selected by the driver adjusts the damping behavior on specific wheels to the road surface condition and the driving style.
Within the selected drive program, the vehicle's damping behavior is regulated depending on the road surface condition and the driver's driving style.
Function requirements
Ignition ON (circuit 15)
Drive train operational
Vehicle speed > 0 km/h
Function
Damping mode can be selected by the driver using the DYNAMIC SELECT switch.
The ADS control unit determines the optimum damping stage in each case and actuates the damping valve units of the four shock absorbers.
The damping valve units are mounted in the damper on the piston rod. The damping valve unit regulates the amount of oil flow from one chamber to another by changing the flow area.
The characteristic of the dampers can be changed using the amount of oil flow. For strong damping, the coil in the damping valve unit remains deenergized.
The flat slide valve closes the flow to the comfort valve and the entire oil flow must pass the main piston.
In order to reduce the body's pitch and rolling motions and to optimize wheel loads and adhesion of the tires, the damping becomes harder during acceleration, braking or steering maneuvers.
