Air suspension systems replace the coil springs in a conventional setup with inflatable rubber membranes that contain pressurised air. This article applies to the Acura RDX. The System Sensors ascertain the current movement of the chassis, by sensing parameters like, Steering angle, Throttle position, Yaw rate, wheel rotation and the actual G-Forces that the drivers input is producing along the selected Driving Mode. Manufacturers need to precisely tune the springs, dampers and anti-roll bars of their cars to achieve the best possible compromise, but there is also a having-your-cake-and-eating-it option: adaptive suspension. The Electromagnetically controlled valves located inside the damper pistons enable the compression as well as rebound valve settings to be adjusted in a stepless manner. The most common type of adaptive dampers are valve-actuated. To control the damper stiffness across different settings, the magnetic field can vary in strength, which allows the cars system to control the firmness or softness of the damper. A computer reads the data as it's sent over by the sensors and adjusts the shocks and springs to create a smooth driving experience. In this way, the chassis can balance out rough roads in a more effective manner resulting in increased driving comfort. This is where cars fitted with adaptive dampers come into their own, as they feature an advanced suspension system that can change the cars ride comfort and handling at the touch of a button.
