- Dynamic signs display latest info in real time
• ‘Current speed limit’, ‘no overtaking’, and more
• If rain sensor lights driver shown safe speed
WOLFSBURG, Germany – “Is there still a speed limit?” Probably every driver has at some time asked this in the city, one the open roads and even on a freeway.
(Germany, of course, still has ‘no limit’ motorways, but you still need to look for the sign.)
Volkswagen’s traffic sign recognition should help. Within the limits of the system, the driver can check on the most important warning and prohibition signs along hisher route.
NO MORE MISSING THOSE ROAD WARNING SIGNS
‘Dynamic Road Sign Display’ (automakers so love their capital letters!), VW says, becomes a “companion” who knows all by constantly monitoring signs with a camera mounted behind the rearview mirror.
What the system records will, VW says (assuming your car has it) display signs you might have missed (as well you might if hurtling along at 200km/h) on each side of the multifunction display as well as on the radio/satnav screen and (if fitted) the head-up display.
Speed limits, exit signs, ‘no overtaking’ signs – and, of course, the corresponding ‘end of …’ signs are displayed to keep the driver up-to-date.
The system’s computer compares not only camera-detected but also from the satnav device. In some cases even dirty or damaged signs will be displayed correctly. It also determines whether the road signs are plausible, relevant or currently valid.
“Incorporating the rain sensor was,” VW says, “particularly smart. It can perceive that the precipitation on the windscreen exceeds a certain level and display ‘when wet’ speed limits.”
