The concept
Speed limit detection
Speed limit detection uses a symbol in the shape of a traffic sign to display the currently detected speed limit. The camera at the base of the interior rearview mirror detects traffic signs at the edge of the road as well as variable overhead sign posts. Traffic signs with extra symbols for wet road conditions, etc. are also detected and compared with vehicle interior data, such as for the rain sensor, and are displayed depending on the situation. The system takes into account the information stored in the navigation system and also displays speed limits present on routes without signs.
No Passing Information
No Passing Information displays in the instrument cluster the beginnings and ends of no passing zones detected by the camera. The system accounts for only the beginnings and ends of No Passing zones marked by signs.
No display is shown:
► In countries where No Passing zones are
primarily identified with road markings.
► On routes without signage.
► Where there are railroad crossings, highway
markings or other situations where no signage
is present, but passing would not be
permitted.
