CONTROL METHOD FOR HYDRAULIC SYSTEM AND RELATED HYDRAULIC SYSTEM Russian patent published in 2017 - IPC F16H61/06 

FIELD: machine engineering.

SUBSTANCE: hydraulic system (1) contains hydraulic actuators (E₁, E₂, F₁, F₂, F₃) of the type of clutch and/or brakes fed with the same line pressure (P_ligne) from one and the same hydraulic circuit (2). The system comprises of an electronic control unit (13), designed to generate a temporary drop in line pressure (P_ligne) during the on-off operation (t₀-t₈) of one of the actuators (E2) at the time of the change in the state of the system, in particular during the change in the gear ratio during the transition from the first gear to the second.

EFFECT: smooth adjustment of torque transmission.
