The method comprises at least the following steps: First, an intended overtaking maneuver is detected by a detection device in the vehicle. For this purpose, the driver's behavior can be evaluated, for example. The activation of a turn signal and / or the activation of a corresponding function on an input element of the vehicle, e.g., via voice command and / or touchscreen and / or a specially provided control element, can be detected.
