CDC - Continuous Damping Control

Semi-active and active suspension systems of ZF Sachs:
For greater safety and comfort
The task:
Over recent decades, electronic systems have substantially enhanced the operation of vehicle mechanical functions - and the field of damping technology is no exception. Development work on the next generation of vehicles is focusing to an ever greater degree on active and semi-active damping and suspension systems. With its electronically controlled damping systems, ZF Sachs is setting new standards in driving safety, comfort, and dynamics.
One of the strenghts at ZF Sachs is that it supplies not only components but also entire systems including both hardware and software. ZF Sachs is also a leading module supplier of active chassis systems such as roll stabilization, spring mount adjustment, and pneumatic suspension. Many of the major vehicle manufacturers rely on the systems expertise of ZF Sachs for their high-end products.
Today's mid-sized and high-end vehicles feature a number of active electronically controlled systems that have thus far operated largely independently of each other. In order to further resolve the compromise between driving safety, comfort, and dynamics, the automotive industry is increasingly seeking to integrate individual systems. ZF Sachs is superbly prepared for this development and will play an active role in shaping it.

Benefit
Benefits:

• Greater safety thanks to optimized wheel damping
• Enhanced driving comfort and dynamics
• Reduced roll, pitch, and vertical motion
• Shorter braking distances thanks to better road contact
• Continuous adjustment in real time
• Faster steering response
• Better control and handling during lane changes
• Available with external or internal valve

The technology:
CDC is an electronic damping system that noticeably increases driving safety, comfort, and dynamics by adjusting damping forces optimally for each individual wheel. A control unit calculates the requisite damping forces within milliseconds, and adjusts the dampers just as quickly. Vehicle sensors monitor values such as body, wheel, and lateral acceleration, and use them to generate the ideal damping forces for each individual wheel on a continuous basis.
CDC是一个电子减震系统，明显提高驾驶安全性，舒适性，以及动态最佳调整阻尼力对每个车轮。一个控制单元计算出所需的毫秒内阻尼力，并调整阻尼器。汽车传感器的监测值，如身体，车轮和横向加速度，并为每个车轮在持续的基础上用它们来产生理想的阻尼力。

CDC® - Skyhook control strategy:
Damping forces for each wheel are individually controlled for the directional movements of wheel and body. Thus they always provide the best possible compensation for vehicle body movement relative to a stationary center position. The skyhook principle keeps the vehicle body as stable as possible, independent of driving and road conditions. The control strategy seeks to calm vehicle body movement, as if the moving vehicle were connected to a hook fixed on the sky. As a result, the body moves along like a sedan chair parallel to the sky.
为每个车轮单独控制定向运动的车轮和机构。因此他们总是尽可能提供最好的补偿运动，车身相对固定中心的位置。保持车身的稳定，尽可能的，独立的驾驶和道路条件。控制战略旨在平静车身运动，因为如果移动的车辆中被连接到了一个钩子固定的天空。因此，该机构作用像轿车像在天空滑行。

那么你只需要知道，这套悬挂让你的车不管走在什么烂路上，但是乘在车上像乘在飞机上一样的感觉，飞行的轿车。
有这样功能的车，还有雪铁龙的C5和C6，大名鼎鼎的hydractive III+， 那个功能更多一些，可以自主调节底盘的高低，自动调节过弯时候车身的侧倾。
看这段视频，魔毯对烈马，对比C6和BMW5的悬挂。

hydractive, 你可以网上搜搜是液压还是空气的。车底盘有4个油葫芦的。

今天试驾了3.0的XJY，感觉CDC底盘并不像这个录像上说的那么神奇。
仔细对比2.4的以后，感觉效果有点，但是不是马上对比，很难感觉出来。
