Active Roll Stabilization

Active roll stabilization uses powered actuators to create or vary anti-roll torque.

Anti-dive and anti-squat route longitudinal tire forces to alter body pitch through suspension geometry.

An anti-roll bar is a torsion spring linking the left and right suspension to resist differential motion.

Heave, pitch, and roll describe vertical translation and rotation of the vehicle body.

Compression and rebound damping oppose damper motion in the two directions of suspension travel.

Elastokinematics describes force-driven suspension deformation; compliance steer is its steer response.

A roll center is a suspension-analysis reference linking lateral force paths and body roll.

Spring-rate curves show how suspension support stiffness changes with component deflection.

Body, battery, occupants, and cargo form most of the mass carried by the suspension.

Suspension motion ratio relates wheel movement to spring, damper, or linkage movement.

Suspension travel spans compression and extension, with wheel and component strokes separated by geometry.

Unsprung mass is the effective mass that moves mainly with the road side of the suspension.

Wheel rate expresses effective vertical suspension stiffness at the tire after linkage effects.
