Said method consists of the following steps: the signal is captured in the other component when passing and the temporal profile of the frequency is recorded in relation to the known temporal profile; a modification in the recorded frequency profile exceeding a first threshold value is detected; two distant wave zones in the frequency profile, lying temporally in front of and behind the detected modification, which displays a frequency modification below a second threshold value, are searched for; the recorded frequency profile is scaled in such a manner that the distance wave zones take the predetermined values; and said distance “a” from the scaled frequency path is determined. The invention also relates to radio beacons, installations and vehicle devices for implementing the method. | 03-21-2013 |
20130084890 | Method and Devices for Determining the Distance Between a Radio Beacon and an Onboard Unit - System and method for determining the distance between a radio beacon and a vehicle device passing in the radio beacon, in a road toll system. A signal having a known temporal profile is emitted by one of the radio beacon and vehicle device. The signal is captured in the other component during the passing of the device and the temporal profile of the frequency is recorded in relation to the known temporal profile; a modification in the recoded frequency profile exceeding a first threshold value is detected; two distant wave zones in the frequency profile, lying temporally in front of and behind the detected modification are determined, the zones displaying a frequency modification below a second threshold value are searched for; the recorded frequency profile is scaled in such a way that the distant wave zones take the predetermined values; and the distance is determined from the scaled frequency profile. | 04-04-2013 |
