Bryan Wood Essentially, the air spring is split into three separate sections, often referred to as a three-chamber setup. In addition, modern vehicles equipped with air suspension systems can automatically lower their ride height at higher speeds to improve efficiency and handling., Hydropneumatic suspension, championed by Citroen with its Hydractive brand of suspension systems, uses a combination of hydraulic fluid and nitrogen filled spheres that are swapped in or out to change the firmness of the ride, to achieve similar overall benefits to standard air suspension systems.. Here, coil springs are replaced by airbags or air springs, often made from a rubber and polyurethane composite. The acceleration sensor detects acceleration value of vertical direction on each position. Using sensor data, each damper incorporates a continuously adjustable valve which raises or lowers damper fluid pressure and thus the speed at which the fluid can flow from one end of the damper tube to the other. However, the ADS on previous Acuras has been a sour spot for reliability. An air suspension system is able to compensate for any heavy loads that might be placed in the back of a vehicle, adjusting the ride height to ensure that the vehicle sits flat and does not sag. It operates independently and communicates with the VDM (vehicle Dynamics Management) Control Unit which manages all 4 corner suspensions. Here is the issue - Check ADS light comes on, you drive for a little bit and the light goes away. In this setting, the dampers iron out uneven road surfaces and at the same time offer a decent level of driving stability.
