Functional Limitations Of Distance Control, Detailed Information - GF30.30-P-0024-01A

Model all (CAR) 

Distance control 

The distance control can be impaired or not function as expected in certain situations due to the system features:

  • Radar sensor dirty or covered
  • Vehicles with Driving Assistance Package: Windshield dirty, fogged up, damaged in area of multifunction camera or multifunction camera covered
  • Snow, rain, fog, heavy spray, glare, direct solar radiation or significantly changing light conditions
  • Driven wheels lose their grip on smooth or slippery roads due to braking or accelerating, vehicle skids
  • Multi-level car park order parking garage
  • Roadway or street with steep downhill or uphill gradient

Obstacles and stationary vehicles 

The distance control can not react to obstacles or stationary vehicles that are not detected by the sensor system. The system may not react sufficiently or at all, for example if the vehicle in front turns and there is a fixed obstacle or a stationary vehicle in front

Curves, curved entrances and exits 

The distance control can only detect vehicles in curves to a limited extent. One's own vehicle can then brake unexpectedly or late.

Vehicles moving across in front of one's own vehicle 

The distance control can detect crossing vehicles by mistake. If distance control is activated, the vehicle can drive off unintentionally (such as at an intersection with cross traffic).

Lane changes by other vehicles 

Vehicles that swing into the regulated distance can cause unexpected braking by the distance control.

Offset driving style 

The distance control may possibly not detect vehicles driving offset to the side. The distance to the vehicle in front becomes too small.

Narrow vehicles 

The distance control does not detect the vehicle in front at the edge of the road due to its narrow width. The distance to the vehicle in front becomes too small.
