Method and device for classifying height of object identified by ultrasound

Abstract

The invention relates to a method for classifying the height of an object identified by ultrasound in the surroundings. Wherein ultrasonic pulses are continuously transmitted and ultrasonic echoes are received again. For each received ultrasound echo, the ultrasound echo is assigned to the map object, or when the received ultrasound echo cannot be assigned to the existing map object, a new map object is created, and when the new map object is created, the height indicator is initialized with a starting value. In a further method step, at least one attribute is extracted from the received ultrasound echoes and / or ultrasound echoes previously assigned to the map object. And changing the height index by a point value. When the value of the height indicator exceeds a predetermined limit value, the object represented by the map object is classified as a high object that cannot be traveled by. The invention further relates to a device for classifying the height of an object identified by ultrasound in the surroundings, which device is designed to carry out the method.

Description

technical field [0001] The invention relates to a method for classifying the height of objects detected by means of ultrasound in the surroundings, wherein ultrasound pulses are transmitted continuously and ultrasound echoes reflected by objects in the surroundings are then received. A further aspect of the invention relates to a device for classifying the height of objects detected in the surroundings by means of ultrasound, which is designed to carry out the method. Background technique [0002] Modern vehicles are equipped with numerous driver assistance systems which assist the driver of the vehicle when carrying out different driving maneuvers. In addition, driver assistance systems are known which warn the driver of dangers in the surrounding environment. In order to implement their functions, driver assistance systems require precise data about the surroundings of the vehicle and in particular precise data about objects located in the surroundings of the vehicle. ...
