1. A method for warning a driver of a motor vehicle of an impending hazardous situation caused by accidental drifting towards or into an opposing traffic lane, the method comprising:

  • determining a virtual vehicle corridor defining a width and directed in the travel direction of the own motor vehicle,determining with a first detection sensor a lane marker separating the lane of the own motor vehicle from the opposing traffic lane,determining a relative position of the own motor vehicle in relation to the lane marker,determining an oncoming vehicle traveling on the opposing traffic lane with a second detection sensor,checking whether the oncoming vehicle enters or has entered the virtual vehicle corridor,checking whether the own motor vehicle will travel across or has traveled across the lane marker based on the determined relative position of the own motor vehicle,checking for presence of additional sensor information indicating an active travel operation or a steering operation by the driver, thus indicating that the detected relative position of the own motor vehicle is caused by driver activity, andoutputting a warning signal or performing an automatic driving mode intervention, or both, when a result of the checking indicates that the oncoming vehicle will enter or has entered into the virtual vehicle corridor and the own vehicle will cross or has crossed the lane marker, thus making a collision likely, and when the sensor information indicates an absence of an active steering operation by the driver,wherein the warning signal is outputted or the automatic driving mode intervention is performed only when no additional marker located proximate to the lane marker separating the own lane from the opposing traffic lane is detected during a predetermined or adaptable time period.
