adaptive ride control 
A few automakers have offered full active suspension systems that boast hydraulic rams at each wheel along with electronics to keep a car level and comfortable. In most cases, the high cost of such elaborate systems outweighs the benefit.

On the other hand, adaptive ride control works by adjusting the shock-absorber damping in response to steering and braking inputs as well as changes in road surfaces. The conventional systems change shock-absorber settings between Soft, Normal, Firm, or Sport. Advanced systems measure the road surface 1,000 times per second and can infinitely vary the damping to maintain a controlled ride.
