A method for kollisionsverhuetung for automatic vehicles, especially in driverless transport systems

摘要

in a method for kollisionsverhu00fctung in automatic vehicles, insbesonere in driverless transport systems, in which a ultraschallimpuls sent and the time until the arrival of the echo is evaluated for a gauging, ultrasonic pulses to the surface of the vehicle. downward inclined sent.the lower area of the sonic lobe is a abschattunggswinkel of at least 30 with the horizontal locked and thus flattened. it is with frequencies of ultrasound of below 100 khz, preferably from 20 to 40 khz, are worked.it can be a bodenentfernung defined which at the shortest distance of an object in the direction of movement in front of the vehicle in a barrier of 1 cm is still covered, the distance between the obstacle and the ultrasonic sensor).all objects in a shorter than the bodenentfernung once or several times by the sonic lobe), to control the vehicle speed. of notstopps identified.
