Abstract
A method for the temperature-dependent control of a pressure control valve of a vehicle comprising an inlet valve and an outlet valve includes detecting a predefined pressure difference to be controlled by the pressure control valve, determining a present valve body temperature, wherein, for this purpose, a temperature change proceeding from a starting temperature is considered depending on at least one detected valve body influencing variable, determining, depending on the pressure difference to be controlled and on the determined present valve body temperature, at least one of a temperature-adjusted pulse duration for the inlet valve and a temperature-adjusted pulse duration for the outlet valve, and controlling at least one of the inlet valve and the outlet valve of the pressure control valve via the particular temperature-adjusted pulse duration in order to effectuate the detected pressure difference at the determined valve body temperature.
