METHOD AND DEVICE FOR OPERATING A SPEED-CONTROLLED FLUID PUMP

A method for operating a speed-controlled fluid pump (102) comprises: - providing an electrical control current for the fluid pump (102), - providing a maximum value (201) for the control current, which corresponds to a maximum permissible pressure on the outlet side of the fluid pump (102), - providing a threshold value (202) for the control current, which corresponds to a further maximum permissible pressure on the outlet side of the fluid pump (102) and which is specified as a function of at least one boundary condition, wherein the threshold value (202) is lower than the maximum value (201), - controlling the fluid pump (102) at most with the threshold value (202) of the control current when a presence of the boundary condition has been determined, in order to limit the pressure on the outlet side of the fluid pump (102) to a value provided for the boundary condition.
