Dynamic ride control
Dynamic Ride Control (DRC) is a name for a chassis technology that reduces the movements of a motor vehicle around the transverse and longitudinal axes, i.e. pitching and rolling, by intervening in the hydraulic shock absorbers .
Two diagonally opposite dampers are connected to each other via oil lines and a central valve each. If the dampers are immersed differently, for example when cornering quickly, the valves act on the oil flow: They strengthen the support on the deflecting wheel, thereby reducing the vehicle's roll and increasing the driving dynamics.
With some vehicles, the strength with which the DRC works can be set in several stages.
Roll describes the rotational movement of a land vehicle around its longitudinal axis (roll axis).
When cornering, a vehicle usually leans outward due to centrifugal force . The resulting roll angle depends on the lateral acceleration , vehicle mass , center of gravity and chassis .

- Hydropneumatics - a suspension system that uses hydraulic cylinders and gas springs (" pneumatics ") to perform the functions of damping and suspension . It was developed by the French car manufacturer Citroën for their cars . Introduced on the rear axle of the Traction Avant in 1954, it became known with the all-round hydropneumatically suspended Citroën DS ("Deesse" - 1955 to 1975).
