In conjunction with MBUX and the Driving Assistance Package, Active Speed Limit Assist, a selectable sub-function of Traffic Sign Assist, is also able to recognise sign gantries and road works signs captured by camera. Known limits, such as 50 km/h in built-up areas or 100 km/h on country roads, are also adopted from the navigation system. Active Distance Assist DISTRONIC adapts the vehicle’s speed to the recognised speed limits automatically (in combination with navigation and traffic sign recognition). In this case, the speed can be adapted in anticipatory fashion based on map data when entering towns. On roads without speed limits, such as stretches on German motorways, the recommended speed – in this case 130 km/h – is adopted as the set speed. This speed can be adjusted by the driver. The desired maximum speed is always adopted in the course of the journey when the speed limit is cancelled. It remains preset until the vehicle leaves the motorway or until the engine is switched off.
