Continuous Damping Control*
Intelligent damping in all situations
Continuous Damping Control (CDC) calculates all forces required from the shock absorbers as a function of the vehicle load and the nature of the road. It does this for braking and accelerating, on bends or on gradients.
A control unit, the system's brain, electromagnetically regulates a proportional valve which determines the flow rate of the oil in the damper. If a higher voltage is present at the valve, the opening in the damper is made smaller. The oil flows more slowly and the damping is "harder". The system calculates and regulates the damping force every 25 milliseconds and thus constantly records the entire driving situation.
Height and pressure sensors in the vehicle supply the data for the calculations. The CAN bus also supplies the damper control system with information; speed, retardation or acceleration signals, lateral acceleration and wheel speed are all included in the precise calculations. The CDC adapts the basic damping under normal conditions to the new circumstances with millisecond accuracy.
The basic damping setting can be varied in two stages, which the driver can conveniently select via a rocker switch. This dynamic stabilisation has further advantages. CDC reduces the tyre wear and protects the roads.
