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 the 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.
