Abstract

Le procédé est un procédé de commande électrique d’un frein de parking pour un véhicule automobile. Le frein de parking comprend un actionneur électromécanique et un actionneur hydraulique destinés à exercer respectivement une force électromécanique (14) et une pression hydraulique sur un même organe de serrage du frein de parking. Dans ce procédé, suite à une commande (12) de désactivation du frein de parking, on réalise les étapes suivantes : a) application d’une pression hydraulique (10) par l’actionneur hydraulique sur l’organe de serrage de manière à augmenter une force de serrage (11) de l’organe de serrage d’une valeur de force prédéterminée, et b) diminution d’une force électromécanique (14) exercée par l’actionneur électromécanique sur l’organe de serrage de manière à diminuer la force de serrage (11) de l’organe de serrage.
