适用范围：Metallised windscreens are produced by spraying small metal particles on one of the glass or plastic layers ofthe vehicle’s windscreen. This leads to a windscreen with high thermal qualities, ranging from far-reducedpower consumption by air-conditioning equipment to short times for de-icing.The production of certain vehicles in Europe which were equipped with metallised windscreens has created amajor problem for the installation and operation of On-Board Units (OBUs) which rely on Dedicated Short-Range Communications (DSRC) for ITS (as the most-widely deployed DSRC ITS application to date, theremainder of this report will refer to Electronic Toll Collection (EFC) but the developed solutions will be validfor all DSRC ITS applications). As is shown in Table 1, windscreen properties have a decisive influence on thetransmission of microwave communication and, for metallised windows, it is essential to compensate theselosses by special measures (Ref 1).As cars equipped with metallised windows are being shipped in large numbers since July 1997, this problemneeds to be addressed.It is important to note that the solution proposed is valid for passenger cars and not for vehicles with near-toverticalwindscreens such as trucks and buses.
