Continuous Damping Control (CDC)

Your benefits

  • Increases driving safety by preventing hazardous weaving of the truck.
  • Reduces the risk of accidents & protects your load

Continuous Damping Control (CDC)

Continuous Damping Control (CDC) calculates and activates the required stiffness of the shock absorbers according to the load and weight-strain on the vehicle as well as the road surface conditions. During braking or acceleration, when cornering, or on hills, this suppresses pitching and rocking movements.

Intelligent damping in all situations

Rapid lane changes, a sharp bend or heavy braking can cause your truck - especially vehicles with a high centre of gravity - and the load to begin to rock. The Continuous Damping Control (CDC) activates the right amount of damping to stabilize the truck and prevent weaving.

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 captures 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 Continuous Damping Control (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 of the load has further advantages: CDC reduces tyre wear and protects the roads.
