A hydraulic pump supplies hydraulic energy to a hydraulic system load. A vehicle controller establishes a commanded rotor speed for the motor or electric machine based on a target pump rotational speed of a pump rotor or pump shaft for operation of the hydraulic pump at a set point or within an operational region consistent with the hydraulic system load or estimated work task of the vehicle for one or more sampling intervals, where the set point or operational region is defined by a hydraulic pump flow rate versus head characterization curve and where the target pump rotational speed can be independent of a rotational speed of the engine shaft (e.g., in a first mode).
