What It Is and How It Works


As its name suggests, the system reads road signs, translates what they say and then combines any relevant information with mapping and directional data displayed by the navigation system or displays it on the car’s gauge cluster or heads up display.


The system consists of a forward-facing camera, which scans the road ahead for traffic signs. The camera is connected to character recognition software, which then reads and identifies any changes described by the signs. It then relays that information to the car’s instrument panel. For example, it enables the car to display the speed limit right in the middle of the information cluster where you can see it better. Consequently, the chances of not noticing a change in speed limit, or the warning of a potential hazard ahead are greatly reduced.
