Dynamic Chassis Control: What are its advantages?

Dynamic Chassis Control
Published at

Dynamic Chassis Control (DCC) makes it possible to set the characteristics of the car's chassis according to the driver's request or automatically depending on the quality of the road.

The control unit automatically adjusts the characteristics of the chassis based on the wheels' position and the body's tilt. In addition, this system allows the driver to choose the desired chassis setting according to his own needs, choosing from three different settings: SPORT, COMFORT, and NORMAL.


How does Dynamic Chassis Control work?

Dynamic Chassis Control uses electrically controlled shock absorbers that allow changing their damping characteristics. These dampers are controlled by the control unit based on data from wheel lift sensors and acceleration sensors. The stiffness of the DCC shock absorbers is adjusted by an electromagnetic valve that controls the oil flow and thus affects the chassis characteristics.

The DCC can automatically change its settings. The system can quickly evaluate shocks caused by bouncing wheels when there is insufficient suspension and automatically adjust the damping effect so that the wheels do not bounce.

Dynamic Chassis Control is also able to adjust the characteristics of the shock absorbers even in the case of hard braking or when driving over an uneven surface, when there would be extreme suspension (hitting the shock absorbers) and thus noise in the cabin.

Dynamic Chassis Control Setup:

The driver selects the desired chassis setting by simply pressing a button - the car will then make the necessary changes in the settings. Each of these three settings (SPORT, COMFORT, NORMAL) affects the shock absorbers' characteristics, the power steering response, and the response to stepping on the accelerator pedal.

Which cars use Dynamic Chassis Control?

For example, Dynamic Chassis Control is used by Volkswagen, Seat, Škoda, and Audi cars. Other car manufacturers also use a similar system but under a different name.

Ford brands the adaptive chassis of its cars as CCD (Continuously Controlled Damping), Opel uses the label AST (Adaptive Stability Technology), and BMW, on the other hand, the Adaptive Drive system, which, however, is extended by the function of active stabilization of the car's tilt.
