Classification: CPC E  F | IPC E  F

Claim 16:
17. The hydraulic system of claim 13, further comprising:
a pressure sensor of the first hydraulic circuit configured to sense or determine a discharge pressure of the first pump and to generate a signal indicative of the sensed or determined discharge pressure of the first pump; and
an electric motor speed sensor configured to sense or determine a speed of the first electric motor and to generate a signal indicative of the sensed or determined speed of the first electric motor,
wherein the controller is communicatively coupled to the pressure sensor and to the electric motor speed sensor and further configured to:
look up, on the efficiency map for the first pump, the sensed discharge pressure of the second pump along a range of speeds including the sensed or determined speed of the first electric motor to identify a corresponding range of pump displacements; and
select, as the target displacement for the first pump, a pump displacement in the range of pump displacements that corresponds to the greatest efficiency.
