DEF AN 115

Electronic suspension system requiring an outside power source, as opposed to the conventional passive system, to continuously control vehicle movement and alter damping characteristics to result in optimum ride. (R)|defg|

CONT AN 120

In its purest form such an active suspension system would consist of hydraulic components, e.g. actuators, pumps and accumulators as well as electrohydraulic servo valves and the control electronics. |a| An active suspension system operates by means of sensors at each corner of the vehicle, which constantly monitor the vehicle's attitude and relay this information to a central computer processor which analyses it and automatically adjusts the suspension to give a smooth ride. |f|

CONT 1: It is to stress that potentially the greatest advantage of active suspensions is that unlike their passive counterparts they can adapt to the various vehicle operating conditions and change their parametes to result in optimum ride for given design constraints and road conditions. |e| We will define active suspensions as suspensions that have their own power source that regularly generates power, and that use this power to freely and continuously control vehicle movement. |g| An active suspension improves performance by using a hydraulic or pneumatic actuator and is controlled electronically, compared to a conventional suspension. Strictly speaking, it is distinguished from a semi-active suspension which employs variable damping force shock absorbers and does not require such power sources as pneumatic or hydraulic pumps. In addition, vibrations can be significantly restrained by detecting approaching road profiles and controlling vehicle actuators accordingly. |i| When damper and body spring functions are combined and jointly controlled, one has a solution which today is called active suspension. |j|

Suspension électronique utilisant une source d'énergie extérieure, contrairement aux suspensions traditionnelles passives, pour contrôler en permanence les mouvements du véhicule et modifier les caractéristiques de suspension afin d'obtenir une conduite optimale. (T)(R)

CONT FR 220

La suspension "active" dans son fonctionnement tient compte des informations extérieures (réponse du véhicule, par exemple) et nécessite une source d'énergie. |f|
