An Insight into Intelligent Damping Control

KYB’s Intelligent Damping Control suspension system is the latest innovative technology developed by KYB and is used on a selection of prestige vehicles. In Europe, it is used by PSA on the DS7 under the name DS Active Scan Suspension. It will also feature on the Peugeot 508 and the new DS9 to be launched in 2021. In Japan, it is available on the Lexus LS and LC and Toyota Crown and Avalon.

This smart technology uses a monocamera behind the windscreen which analyses the road profile and sends it to the IDC electronic central unit. It works with four height sensors and three accelerometers to measure the vehicle’s reactions including speed, braking and steering angle.

The control unit continuously calculates the optimum shock absorber settings to mitigate any irregularity, improving comfort to create a unique and smooth driving experience. It does this via a proportional solenoid valve on each damper which adjusts the inner pressure between the upper and lower chambers, giving individual control of both the compression and rebound on all four wheels.

Testing shows the benefits are especially noticeable in the rear seats, with the scanning system reducing the oscillation which can occur over bumps. This may sound like just improvements in driving comfort, however it will also have a positive effect on safety. Smoother driving means all four wheels will maintain a better contact with the road, allowing for safer steering and braking. A smoother ride will also reduce driver fatigue.

Juan Carlos Diez, Executive Director of KYB Europe Aftermarket, explains “This original equipment system is another great example of the world class technological advances created by KYB research and development engineers here in Europe and in our Japanese headquarters”.
