Active suspension control
Active and semi-active suspension systems are a desirable feature in luxury and sports cars, with comparatively low-production volumes.
In contrast to passive suspension systems, which rely on springs and shock absorbers to dampen the effects of bumps and road irregularities, active suspension systems use sensors to monitor the road surface and the vehicle's motions. This information is used to control actuators that apply forces to the suspension components, which allows the system to actively adjust the suspension in real time to provide a smoother ride and improved handling.

Advanced suspension systems improve comfort, handling, and safety
Active suspension control (ASC) is a technology that uses sensors and actuators to actively control the suspension of a vehicle. This can be used to improve ride comfort, handling, and safety.
There are a number of different applications for ASC:
- Ride comfort: ASC can be used to improve ride comfort by reducing vibrations and oscillations. This can be done by adjusting the stiffness of the suspension or by using actuators to actively dampen the vibrations.
- Handling: ASC can be used to improve handling by reducing body roll and improving the responsiveness of the suspensions. This can be done by adjusting the stiffness of the suspensions or by using actuators to actively control the roll of the vehicle.
- Safety: ASC can be used to improve safety by reducing the risk of accidents. This can be done by improving the driver's ability to control the vehicle in difficult conditions, such as when driving on wet or icy roads.
