  • Patent number: 11871317
    Abstract: The present disclosure relates to a method for controlling a data interchange between a control device of a motor vehicle and an external device. The motor vehicle has multiple vehicle functions each having at least one associated subservice. Based on the subservice, the respective vehicle function is performed and the data interchange with the external device takes place independently of the activity of the vehicle function. If the control device receives a deactivation signal for one of the vehicle functions, it deactivates this at least one vehicle function and checks whether one of the subservices is associated with at least one other vehicle function that is currently activated. If a subservice is not associated with a currently activated vehicle function, this subservice is deactivated, as a result of which the data interchange between the control device and the external device is terminated by this subservice.

  • Publication number: 20230417205
    Abstract: A method for operating a fuel tank arrangement for a motor vehicle. The fuel tank arrangement has a fuel tank, a hydrocarbon filter and a pump. The fuel tank is fluidically connected via a tank shut-off valve to the hydrocarbon filter and the hydrocarbon filter is fluidically connected, on the one hand, via the pump to an external environment of the fuel tank arrangement and, on the other hand, via a purge valve to an intake tract of an internal combustion engine. A first leakage test mode is carried out when the pressure in the fuel tank is greater than a pressure threshold value, in which a shut-off valve arranged in terms of flow between the pump and the external environment is closed and the tank shut-off valve is opened.
