Abstract (en)

[origin: WO2016071285A1] The invention relates to a method for producing a set of characteristic curves of a fluid pump (13) of a pressure-dependent fluid conveying system (10) in a working range of the fluid pump (13). In this connection the fluid conveying system (10) comprises a current-controlled electric motor (11) which is controlled by an engine control unit (12) by means of a control current. The fluid pump (13) is driven by the electric motor (11). The method comprises the step of setting the control current to a predetermined value, and the steps of changing a flow volume of the fluid conveying system (10), according to which the control current is set. Furthermore, a quantity of data which describes a pressure in the fluid conveying system is recorded as a function of the change in the flow volume. The steps of setting, changing and recording are repeated for a predetermined number of repetitions and predetermined control currents. A set of characteristic curves is produced from the recorded quantity of data. The invention relates to a use of a limited valve, use of a staging valve, and a control device for a fluid conveying system (10).
