Active (SA) suspensions are often found on today's high-end production sports cars and feature damping control on all four corners. The control objective of SA suspension is to counteract for heave, roll and pitch. This control is achieved by pairing a microprocessor with four shock absorbers that have a continuously variable (and controllable) damping coefficient. On occasion, these dampers are paired with pneumatic springs to provide ride height/leveling control.

Potential customer benefits of the SA suspension system include:

• An adjustable ride, optimized for comfort or handling performance
  • Suspension will automatically adjust according to road conditions
  • User has the option to select the firmness of the suspension
• There is no change in size from traditional suspension systems.
