Abstract
Official abstract text for this publication.
A method for detecting the wheels of a vehicle that is traveling on a roadway in a travel direction and whose wheels project downward from the vehicle body and are at least partially exposed laterally at the level of the vehicle body, with the steps: emitting a concentrated electromagnetic measurement beam with a known temporal progression of frequency from the side of the roadway onto an area a predetermined distance above the roadway and at a slant with respect to the travel direction, receiving the measurement beam reflected by a passing vehicle and recording the temporal progression, relative to the known progression, of its frequency, and detecting a rectangular pulse occurring in the recorded progression within the time period when the vehicle body passes, as a wheel.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for detecting a wheel of a vehicle that is traveling on a roadway in a travel direction, the vehicle having a vehicle body and wheels, which project downward from the vehicle body and are at least partially exposed laterally at the level of the vehicle body, the method comprising: emitting a concentrated electromagnetic measurement beam with a known temporal progression of frequency from a side of the roadway onto an area at a predetermined distance…
