Pressure control by phase current and initial adjustment at car line

A closed loop control system for a fuel pump based on characteristics of speed, pressure, and current. The pressure generated by the pump system is increased at the point in time when the pump system is working against a dead head system (i.e., coasting) to a level that a calibration valve is opened to a determined working point. By measuring the characteristic phase current as a function of the speed, the characteristic is able to be compared, with the pre-calibrated value of the hardware to perform an error compensation algorithm. The error compensation is overlaid with the standard pressure characteristic as a function of speed and phase current, and uses the pre-calibrated opening pressure value (i.e., the inflection point) of the calibration valve and/or in addition the change of the speed to the initial (first calibration), or to a sliding average therefrom.
