A camera on the inside of the windscreen records speed limit signs, for example at the edge of the road, on overhead gantries or in roadworks. The data is cross-referenced against the information in the navigation system and can be displayed in both the instrument cluster as well as in the navigation system's map view.

No-overtaking zones and the signs signalling their end are also registered and displayed, while in the case of signs imposing access restrictions, an acoustic warning is additionally emitted together with a visual warning in the instrument cluster. This helps to ensure that you always have the best possible information, even if you have perhaps overlooked a sign - something which can easily happen on long journeys with frequently changing traffic signs.

Changes may have been made since these images and films were produced.

The camera for Traffic Sign Assist permanently monitors the area in front of your vehicle. The image processing system it uses is able to identify the typical round shape of the relevant traffic signs, including signs providing additional information, from among all those around them.

The Traffic Sign Assist camera permanently monitors the area in front of your car. With the aid of image processing, the system is able to pick out the typically round shape of the appropriate traffic signs, along with any supplementary signs, from the surroundings being monitored.

 

The captured data is cross-referenced in real time against the information contained in the digital road maps stored in the COMAND Online System, and the current speed limit is then displayed in the instrument cluster and also shown in the COMAND Online display.

 

If the camera does not detect any road signs specifying a speed limit, or if a speed limit has been lifted, the system displays statutory speed limits based on the navigation system data. In Germany, for example, this includes a maximum speed of 100 km/h on country roads, and 50 km/h in urban areas.

 

Traffic Sign Assist increases your safety and can save you from having to pay out money on fines. That's because it helps you to keep to the maximum permissible speed limit for the area you are in and alerts you to restrictions on overtaking. And should you ever be about to make a wrong turn into a road against the stipulated flow of traffic, Traffic Sign Assist can alert you when the appropriate signs are present via a warning in the instrument cluster as well as an audible signal.

 

The data gathered is compared in real time with information from the digital road maps stored in the COMAND Online System, so that the applicable speed limit can then be displayed both in the instrument cluster and on the COMAND Online display screen.

  

If the camera is unable to detect any road signs indicating a speed limit, or the end of a speed limit, the system will display the legally applicable speed limits derived from the navigation data. In Germany, for example, these include a maximum speed of 100 km/h on country roads and 50 km/h in built-up areas.

 

Traffic Sign Assist is available in many markets.

It enhances your safety and can help you avoid speeding fines, by making sure you keep within the speed limit at any given point and alerting you to no-overtaking restrictions. Furthermore, should you ever inadvertently enter the slip road to a motorway or similar major road against the direction of travel, Traffic Sign Assist - assuming the presence of relevant signs - will alert you to the fact with a clear warning sign in the instrument cluster and an acoustic signal.
