1. A method for detecting objects having a low height by using a system for obstacle detection in a vehicle, the method comprising: performing one of the following: (i) continuously recording a distance from an object using distance sensors, and (ii) recording the distance from the object at specified intervals, wherein the system for obstacle detection includes the distance sensors for ascertaining the distance from objects and an evaluation arrangement; checking whether the object continues to be recorded by the distance sensors when approaching the vehicle, in response to falling below a specified distance, or whether it vanishes from a detection range of the distance sensors; and detecting the object, which vanishes from the detection range of the distance sensors, as being an object of low height.
