Abstract
(EN)
A controller (16) for controlling a damping system (12) is disclosed. The system (12) has at least two dampers (12a-12d) for damping between sprung and unsprung masses (7, 2) in at least one of compression and rebound directions. A sensor (190a-190d) generates position signals (17a-17d) representative of the displacement between the sprung and unsprung masses (7, 2). A regulator (40a-40b) responds to at least one of the independent compression and rebound control signals (25a-25d, 27a-27d) for adjusting, respectively, at least one of compression and rebound resisting forces of the dampers (12a-12d) between the masses (2, 7). The controller (16) includes a processor (15) that is responsive to signals representative of the position signals (17a-17d) for forming the compression and rebound control signals (25a-25d, 27a-27d) for the regulator (40a, 40b) as a function of motion between the masses (2, 7) or a motion of a vehicle (8) in which the dampers (12a-12d) are located.

La présente invention concerne un contrôleur (16) destiné à la gestion d'un système d'amortisseurs (12). Ce système (12) se compose d'au moins deux amortisseurs (12a - 12d) assurant l'amortissement entre des masses suspendues par ressorts et non suspendues par ressorts (7, 2) dans le sens de la compression et/ou du rebond. Un capteur (190a - 190d) génère des signaux de position (17a - 17d) représentant le déplacement entre les masses suspendues par ressorts et non suspendues par ressorts (7, 2). Un régulateur (40a, 40b) réagit à l'un au moins des signaux de commande de compression et de rebond indépendants (25a - 25d, 27a - 27d), afin de réguler, respectivement, l'une au moins des forces de résistance à la compression et au rebond des amortisseurs (12a - 12d) entre les masses suspendues par ressorts et non suspendues par ressorts (7, 2). Le contrôleur (16) comporte un processeur (15) qui réagit aux signaux représentant les signaux de positions (17a - 17d), ce qui permet de produire les signaux de commande de compression et de rebond (25a - 25d, 27a - 27d) destinés au régulateur (40a, 40b), en fonction du mouvement entre les masses (2, 7) ou du mouvement d'un véhicule (8) dans lequel se trouvent les amortisseurs (12a - 12d).
