Abstract
The present invention discloses a method and operating liquid container system for controlling the internal pressure of an operating liquid container of a motor vehicle, wherein the method includes determining an internal pressure of the operating liquid container by means of a pressure sensor arranged in an operating liquid container interior; comparing the determined internal pressure with a predetermined maximum internal pressure by means of an electronic control device; outputting an opening signal from the control device to a vent valve that is arranged in a vent line or between the operating liquid container interior and the vent line, wherein the vent line fluidically connects the operating liquid container interior to the atmosphere when the determined internal pressure is equal to the maximum internal pressure or above the maximum internal pressure; and transferring the vent valve into an open position.
