Abstract:
A method for detecting critical driving situations of motor vehicles, in particular for preventing collisions with an object in front of an own vehicle, has the following steps: determining a path profile of the own vehicle from the time progression of the foreseeable acceleration; acquiring a current distance and a current relative velocity of an object in front of the own vehicle; determining a path profile of the object from the time progression of the foreseeable acceleration; comparing the path profile of the own vehicle with the path profile of the object; and if the two path profiles intersect, determining a probable collision time of the own vehicle with the object; establishing a time before the probable collision time comparison of this time with the probable collision time determined; and if the probable collision time lies before the established time, issuing a warning to the driver of the own vehicle.
