According to a first aspect of the invention, a method for supporting a vehicle's overtaking maneuver is proposed. 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. Subsequently, a lane keeping control system of the vehicle regulates the lane guidance such that it switches from lane center guidance to laterally offset lane guidance, e.g., lane marking-controlled.This means that under normal circumstances (i.e., outside of overtaking maneuvers), the lane keeping system essentially keeps the vehicle in the center of the currently driven lane.
