This new feature of the Adaptive Cruise Control system can automatically adjust the car’s set speed in response to speed limits on traffic signs. For example, when a SUPERB travelling on the motorway enters a conurbation, it decelerates to the speed limit of 80 km/h, before accelerating again to the motorway speed limit on leaving the city.

This system provides more safety and comfort in traffic jams and stop-and-go traffic. Traffic Jam Assist taps into the DSG transmission, the Adaptive Cruise Control and Lane Assist systems by having them “merge” with it.

A picture processing module searches scanned pictures for known traffic signs and compares the results with the navigation data. The system processes speed limit signs, no-overtaking signs and any supplementary instructions, as well as associated restriction clearance signs, and then displays them to the driver.
