Definitions

  • the present invention relates to a method for identifying vehicles for operating a parking garage or a parking lot according to the preamble of patent claim 1.
  • the present invention has for its object to provide a method for the identification of vehicles for operating a parking garage or a parking lot, by the implementation of this goal can be achieved inexpensively with little effort. This object is solved by the features of claim 1. Further embodiments and advantages of the invention will become apparent from the dependent claims.
  • a method for identifying vehicles for operating a parking garage or a parking space, in which a vehicle is identified at least on the basis of the sound pattern from the drive train comprising a drive unit emitted sound profile in the auditory and / or ultrasonic range in at least one speed range.
  • the method according to the invention is based on the finding that each vehicle can be unambiguously identified on the basis of the emitted sound profile at standstill while the drive unit is running or while driving in at least one speed range.
  • the vehicle before or during the entry of a vehicle into a parking garage or a parking lot, when the vehicle is not in motion, which is the case when the vehicle is in front of an access control device of the parking garage or the parking lot, or if as constant as possible Speed is maintained within a defined speed range, which, for example while driving in a driveway is the case, the sound profile of the vehicle recorded in the auditory and / or ultrasonic range by at least one microphone and associated with this vehicle and the respective speed range.
  • acoustic identification signature is generated in a server or central computer, which is based on the frequency spectrum of the recorded sound profile and / or its temporal change.
  • the speed and thus the speed range can be determined for example by suitable sensors, which are provided at the entrance.
  • the speed ranges may be defined, for example, as follows: 0, 1-10, 11-20, 21-30, 31-40 km / h. Alternatively, the speed ranges may be finer graded.
  • a defined gear is engaged per defined speed range; for example, for a speed between 0 and 10 km / h, it is assumed that the first gear is engaged.
  • Acoustic identification signatures in the same speed range can hereby be checked for similarity, for example, by adding up the pointwise differences in the frequency spectrum in order to obtain a similarity measure for two signatures. If this code is smaller than a predetermined threshold, it is assumed that it is the signature of the same vehicle.
  • the creation of an acoustic identification signature from the recorded sound profile or measurement signal can be based on the extraction and subsequent selection of a defined set of signal properties.
  • Properties which are suitable for this purpose are e.g. Time domain properties, such as the energy content of the signal within a short-term energy window, spectral properties, e.g. the spectral centroid of the signal (spectral centroid) or the current dispersion around a frequency range (spectral spread), band energies, where the spectrum is divided into defined frequency bands within which the existing energy of the signal is calculated and the so-called Mel Frequency Cepstral Coefficients (MFCC coefficients), which are known from speech recognition and result in a compact representation of the frequency spectrum. The calculation of these coefficients is extensively described in the literature and well known to those skilled in the art.
  • Acoustic identification signatures in the same velocity range can hereby be checked for similarity by summing up the pointwise differences of the signal properties of the set of signal properties, which is optimal for a given field of application, in order to obtain a measure of deviation.
  • an identification signature for the same speed range is added to the existing data record if the current number of identification signatures for this speed range does not exceed a predetermined threshold value.
  • the data set assigned to a vehicle can therefore comprise a plurality of acoustic identification signatures of the vehicle in the field of audible sound and / or in the ultrasound range for different speed ranges.
  • acoustic identification signatures may additionally be stored as a function of the engaged gear.
  • a data record is created which contains payment data for the driver or a billing address in addition to the acoustic identification signature for the current speed range. This information can also be added to the record later. In this way, as part of a pay-per-use scenario, access control and parking time calculation can be performed without any interaction with the driver of the vehicle. Further, a number of a driver's mobile phone may be input and assigned to the vehicle.
  • the vehicle is detected during retraction on the basis of the sound profile or the acoustic identification signature or registered as first entering vehicle as described, the vehicle is detected on the basis of the sound profile or the acoustic identification signature and from the difference between the Einfahruhrzeit and the Ausfahruhrzeit the actual parking time is calculated.

  • the vehicle is again based on the sound profile or the acoustic identification signature is detected, wherein from the difference between the Einfahruhrzeit and the Ausuhruhrzeit the actual parking time is calculated;
  • the driver can pay by conventional means, such as his credit card, for example, directly at the exit column without having to trigger as usual a parking ticket at a machine or at a checkout.
  • Further possibilities exist by linking the exit column with mobile devices, preferably with mobile phones, for example for the purpose of reading out payment information stored in a mobile telephone. Interfaces of the mobile devices can be used here, in particular to increase the comfort, such as a bar code display on the display, NFC functions or Bluetooth or other suitable functions.
  • a vehicle tracking of the incoming vehicles can be carried out based on the sound profile emitted by a vehicle, so that a continuous location and localization is made possible.
