Active Suspension Systems - Introduction Active or adaptive suspension technology controls the vertical movement of the wheels with an onboard system rather than the movement being determined entirely by the road surface. The system virtually eliminates body roll and pitch variation in many driving situations including cornering, accelerating, and braking. This technology allows car manufacturers to achieve a greater degree of ride quality and car handling by keeping the tires perpendicular to the road in corners, allowing better traction and control. 74
Control System Hardware Implementation - Active Suspension Systems Studies • The vehicle suspension system is responsible for driving comfort and safety as the suspension caries the vehicle body and transmits all forces between the body and the road. • Active systems enable the suspension system to adapt to various driving conditions. By adding a variable damper and/or spring, driving comfort and safety are considerably improved compared to suspension setups with fixed properties. 75
