(FR) PROCÉDÉ DE DÉTERMINATION D'UN PARAMÈTRE DE TEMPS DE RÉPONSE D'UNE CHAMBRE DE FREIN D'UN SYSTÈME DE FREIN POUR UN VÉHICULE, PROCÉDÉ DE COMMANDE D'UN SYSTÈME DE FREIN POUR UN VÉHICULE, ET SYSTÈME DE FREIN POUR UN VÉHICULE
Abstract
(EN)
A method for determining a response time parameter of a brake chamber (120) of a brake system (110) for a vehicle (100) is presented. The brake system (110) comprises an electronic pressure modulator (130) configured to modulate pressure in the brake chamber (120) and a solenoid valve (140) for the brake chamber (120). The method comprises a step of detecting an end of a fallback slope of a pressure signal (135) as measured at the electronic pressure modulator (130) after a pulse of the solenoid valve (140). Furthermore, the method comprises a step of setting the response time parameter of the brake chamber (120) depending on the detected end of the fallback slope.
(FR)
L'invention concerne un procédé de détermination d'un paramètre de temps de réponse d'une chambre de frein (120) d'un système de frein (110) pour un véhicule (100). Le système de frein (110) comprend un modulateur de pression électronique (130) conçu pour moduler la pression dans la chambre de frein (120) et une électrovanne (140) pour la chambre de frein (120). Le procédé comprend une étape de détection d'une fin d'une pente de repli d'un signal de pression (135) telle que mesurée au niveau du modulateur de pression électronique (130) après une impulsion de l'électrovanne (140). En outre, le procédé comprend une étape de réglage du paramètre de temps de réponse de la chambre de frein (120) en fonction de la fin détectée de la pente de repli.
