Abstract (en)
[origin: WO2022013329A1] A control method for actuating a combined motion of a plurality of hydraulic implements of a work or agricultural machine comprising a flow sharing hydraulic circuit, the method comprising a preliminary step of grouping said plurality of hydraulic implements in at least two sets (L, M, H) having different supplying priority, a first step of acquiring a first flow of available hydraulic liquid (A_F), generated by the hydraulic pump, a second step of 15 calculating a second flow of hydraulic liquid (R_F). overall required to actuating said sets of hydraulic implements, a third step of comparing said first flow with said second flow and when said second flow is less than the first flow, then a fourth step (RED) of calculating a reduction (RED) of the second hydraulic flow is executed iteratively from the lowest priority set (L) to the highest priority set (H) till the second flow equates the first flow.
