Abstract: A method and a device for detecting a living being, in particular a small child, in a vehicle. A transmitter provides a signal that is influenced by the living being. The influenced signal is provided to a receiver that provides the signal to a first decision module. The first decision module uses the signal to ascertain whether a vital state of a living being is present. The signal is provided to a second decision module if a living being is ascertained, wherein the second decision module ascertains whether the living being is an adult. If it is ascertained that the living being is not an adult, a warning signal is output using a signal generator. A vehicle having such a device is also provided.

Abstract: A method for purging a fuel tank includes providing a three-way valve connected to the fuel tank via a first purging line, connected to a second purging line opening into a suction duct and connected to a third purging line opening into an adsorption container. A first path can be released in the three-way valve, based on the pressure inside the fuel tank exceeding a first predetermined opening pressure inside the fuel tank and the engine being in operation, such that the fuel vapors are caused to be purge out of the fuel tank into the suction duct. A second path can also be released in the three-way valve, based on the pressure inside the fuel tank exceeding a second predetermined opening pressure inside the fuel tank and the engine being not in operation, such that the fuel vapors are caused to be purged out of the fuel tank into the adsorption container.
