<p>The invention relates to a hydraulic system (1), in particular for an automatic transmission of a motor vehicle, which comprises hydraulic actuators (Ei, E2, Fi, F 2, F3), such as clutch and/or brake actuators, supplied at the same line pressure (Piigne) by a single hydraulic circuit (2). The system comprises an electronic control unit (13) configured such as to cause a temporary drop in the line pressure (Piigne) during the closing operation (t0- t8) of one of the actuators (E2) during a change of status in the system , particularly during a gear ratio change from a first ratio to a second ratio.</p> |
