Traffic sign recognition
Camera-based traffic sign recognition detects traffic signs such as speed limit signs (including digital signs), no passing zones, entry restriction signs and other auxiliary signs, and it shows them to the driver in graphic form.
They then appear in the driver information system and/or the Audi virtual cockpit as well as in the head-up display. The camera on the windshield also detects temporary speed restrictions such as in construction zones, as well as time- and weather-conditional restrictions. The system shows the currently applicable speed limit. For example, if a lower speed applies when the road is wet, this value is displayed – if the windshield wipers are on. Speed limits that are only in force at certain times of day are only shown at those times. In addition, the driver can choose a warning threshold as an offset to the legal speed limit. When this threshold is exceeded, a visual warning is given.
