Beschreibung
Zusammenfassung:	A method for venting the tank of a vehicle, a device for venting the tank of a vehicle, as well as a vehicle are provided. In this context, the vehicle in which the method is employed has an internal combustion engine that can be operated with a fuel, an air supply system, an exhaust gas system comprising at least an exhaust gas turbocharger, a fuel tank that is designed to supply the internal combustion engine with fuel, and a fuel vapor sorption system. It is provided that, in the method or by means of the device, a drive flow in the air supply system is regulated as a function of an altitude reserve of the exhaust gas turbocharger and as a function of an engine load point, so that the flushing air volume flow of the tank venting system that ensues is determined and can be supplied as a function of an altitude rotational speed of the exhaust gas turbocharger and as a function of the engine load point.
