Abstract
A device for controlling a solenoid valve that controls the through-flow of a medium in a closed-loop manner includes a control procedure implemented by the device. The control procedure is configured at least in regions as a ramp function. The ramp starts with a ramp start current intensity that is less than an opening start current intensity of the valve at which the valve starts to open. The ramp ends with a ramp end current intensity that is greater than an opening end current intensity at which the valve is fully open. The device is configured to one or more of determine and adjust an amount of the ramp start current intensity in dependence upon a pressure. The amount determined and/or adjusted takes into consideration a pressure of the medium against which the solenoid valve opens.
