<p>A method for controlling a pressure supply unit 10, which includes a drive 12 and a pump 14, for a fluid assembly 1, wherein the drive 12 is controlled via control signals in order to implement a pressure and/or fluid delivery requirement. Physical magnitudes, such as the position, acceleration, speed or travel of a movable pump element or structure borne noise, fluid pressure or oscillations are captured and analysed to determine oscillation and/or pulsation emissions in operation, the control signals, such as the shape or duration of the voltage or current feed course, being changed so that the determined oscillation and/or pressure pulsation emissions in operation are below a predetermined limit value, while the efficiency remains essentially the same. Also claimed is the fluid assembly, a computer program product and a computer program to carry out the method.</p> |
