Definitions

  • An advantageous variant of the method provides in this context that upon reaching a model-related and / or pre-calculated reference pressure, a tank opening of the fuel system is released for opening, whereby a pressure measurement within the fuel system can be dispensed with.
  • the closure valve is opened and the pressure within a fuel tank is changed.
  • a pressure can be calculated model that takes into account pressure changes within the fuel tank due to, for example, the number of gas discharges and their amount or outgassing at the last refueling.
  • the measured pressure and the modeled pressure can be compared and it can be determined whether or not there is a leak.
  • an overpressure or underpressure can be generated in the fuel tank in order subsequently to be able to carry out an active pressure test. If no critical pressure change takes place within a certain time interval, a leakage within the fuel system can be excluded.
  • the fuel system in particular a filter device of the fuel system, is cleaned of fuel gases, in particular of hydrocarbons.
  • the filter device of the fuel system is purged and cleaned with ambient air and the pressure within a fuel tank is changed.
  • an activated carbon filter insert can be regenerated particularly well.
  • the state of fullness of the activated carbon filter cartridge may be calculated cumulatively or alternatively based on the number of gas discharges and the associated hydrocarbon content modeled.
  • the features with regard to the third operating state are also advantageous without the other features of the invention, since these features advantageously continue known methods for operating a fuel system.
  • the pressure within the fuel system in particular within a fuel tank, can be changed in different ways. Often it is already sufficient to open a corresponding valve to effect a pressure change, in particular a pressure reduction. Cumulatively or alternatively, it is advantageous if the change in pressure within the fuel system is carried out by means of commissioning a range extender. In this case, for example, parts of the fuel vapors formed can be burned with the range extender in almost any desired manner. In this respect, the pressure within the fuel system can advantageously be adjusted system-internally by means of the range extender without the need for an immediate pressure equalization with the environment.
  • a situation-related pressure can also be set by means of the range extender as a function of a model-related and / or predicted reference pressure.
  • the term "situation-related pressure” describes the possibility of being able to change the pressure within the fuel system with regard to certain operating situations in a required manner, whereby this situational pressure can be adjusted as a function of a model-related and / or predicted reference pressure
  • range extender preferably describes an internal combustion engine specially tuned to a vehicle with an electric drive, which does not serve as the primary drive for the present vehicle ,
  • a generator for generating electrical energy is operated by means of the range extender, in order to either supply a storage device for electrical energy or to supply the electric drive of the present vehicle directly with electrical energy.

It is understood that the individual components of the present fuel system are fluidly connected to one another by means of a suitable conduit system.
  • the fuel system is designed here in terms of pressure as a closed system.
  • the present device can be made particularly compact and lightweight, so that it can be advantageously used on a large number of electric-powered vehicles.
  • the apparatus further includes a pressure sensor for detecting a current pressure within the fuel system so that the current pressure within the fuel tank system is always known.
  • the device for controlling and / or regulating comprises a vehicle control unit (VCU), a hybrid control unit (HCU) and / or a range extender control unit (RECU).
  • VCU vehicle control unit
  • HCU hybrid control unit
  • RECU range extender control unit

  • an overpressure within the fuel system can be reduced and a tank opening of the fuel system can be released for opening upon reaching a model-related and / or predicted reference pressure.
  • the range extender is put into operation shortly before refueling in order to advantageously reduce excess pressure within the fuel system. so that a fuel cap can then be opened.
  • the overpressure is reduced to ambient pressure or slightly above it. This process can be used if, for example, the closure valve can not be opened due to a malfunction.
  • the object of the invention is also achieved by using a range extender of an electric vehicle to reduce overpressure in a fuel system of the electric vehicle.
  • a release of the tank opening or a relevant fuel filler flap can thus be made structurally particularly simple by means of a differential pressure measurement, in particular by means of a single pressure sensor.
  • Such a pressure sensor is preferably associated with the fuel tank in order to be able to carry out a particularly accurate leak diagnosis in the region of the fuel tank.
  • the object of the invention is also achieved by use of a range extender of an electric vehicle for generating a negative pressure in a fuel system of the vehicle with electric drive.
  • the fuel system in particular a filter device of the fuel system, of fuel gases, in particular of hydrocarbons, can be cleaned.
  • the range extender may remain inoperative for a longer period of time, whereby fuel vapors arising in the fuel system can not be dissipated by combustion in the internal combustion engine, as is usual in an internal combustion engine-driven motor vehicle.
  • the fuel vapors may leak into the environment due to a pressure increase when the range extender is not used for a long period of electric driving.
  • a fuel gas line closure valve is arranged in a fuel gas line upstream of the filter device, in particular between the filter device and the fuel tank.
  • a fuel supply closing valve is arranged in a fuel supply line in front of the range extender, in particular between the range extender and the fuel tank.
