Method and apparatus for warning about obstacles which are not high and/or wide enough to drive through

摘要

The method involves scanning ahead-lying overhead obstacles, ahead-lying lateral obstacles and respective roadway surface for detecting passage-relevant data of the obstacle. The determined passage-relevant data of the obstacles are compared with passage-relevant data of a motor vehicle e.g. bus. A warning signal is provided to the driver when the data of the vehicle exceeds the data of the obstacle. Passage height and/or passage width of the obstacle are determined and the passage height and/or the passage width of the obstacles are computed from angle and space information. An independent claim is also included for an arrangement for warning of an obstacle with non-sufficient passage height and/or non-sufficient passage width for a motor vehicle.
