METHOD FOR OPERATING A FUEL SYSTEM AND DEVICE FOR MODIFYING A PRESSURE IN A FUEL SYSTEM

摘要

In order to further develop known fuel system operating methods for a vehicle, the invention proposes a method for operating a fuel system of a vehicle having an electric motor, wherein a pressure within a fuel tank of the fuel system can change according to the situation, the method being characterized in that the pressure within the fuel tank is monitored and, if necessary, is changed as a function of a reference pressure related to the model and/or calculated in advance.
