Real-time damping

Real-time damping  - Overview - Lincoln MKT

Compared to the fixed-rate damper standard on the 2012 MKT, the CCD damper on the 2013 MKT offers dramatically expanded control range. CCD utilizes 46 inputs to feed data to a sophisticated control unit that continuously monitors more than 23,000 packets of information per second.

The CCD control module reacts to the data by calculating the optimal damping force every 2 milliseconds or 500 times per second. Mechanical adjustments typically occur 20 times per second, but can be as rapid as 50 times per second. On average, large damper force adjustments (such as firm to soft) occur in just 11 milliseconds. For engineers, mechanical actions that occur in less than 13 milliseconds are considered real-time actions.

CCD constantly reads the road surface and continuously adjusts the suspension in real time within the three selectable ranges - Sport, Normal and Comfort. CCD operates so quickly that it can react pre-emptively.

CCD recognizes, for example, when the Lincoln MKT is about to encounter a typical pothole. The system instantly tightens damper control to prevent the wheel and tire from crashing down into the full depth of the pothole. Typically, the damping rate increases by more than 150 percent vs. the system's softest setting, helping to smooth out an otherwise harsh and jarring event. The system is so quick that inputs received at the front wheels are used to prepare the rear wheels to deliver a better driving experience.

"CCD is always active, refining the ride of the new MKT," said Brian Naspinsky, Lincoln Vehicle Integration engineer. "CCD helps reduce body roll by up to 20 percent, making the MKT feel tighter and more buttoned down. Understeer on the MKT has been reduced by approximately 25 percent, so the car feels more eager and ready to respond. Simultaneously, CCD also makes it possible to provide a smoother, more confident ride over virtually any road surface."
