Keeping your distance. Staying ahead.

The system helps to avoid rear-end collisions and accidents with crossing pedestrians and can mitigate the consequences of accidents.

The system helps to avoid rear-end collisions and accidents with crossing pedestrians and can mitigate the consequences of accidents.

Radar sensors and a stereo camera continuously register and evaluate the situation ahead of the vehicle. In so doing, the system assesses not only the vehicle ahead, but also – up to a speed of 72 km/h – crossing vehicles Crossing traffic can only be detected in the speed range from 7.2 km/h to 72 km/h and when the crossing vehicle is travelling at no less than 5.4 km/h and no more than half of your own speed.and pedestrians.

The individual functions:

  • Warning of a danger of collision.
On detecting a danger, the system provides the driver with a visual warning when the distance from the vehicle ahead is no longer safe and outputs an audible alarm when a danger of collision applies.
  • Increase in brake pressure as appropriate to the given situation.
When the driver identifies a risk of an accident and applies the brakes, Active Brake Assist with cross-traffic function supplies additional brake pressure as appropriate to the given situation to - ideally - prevent a collision.
  • Autonomous partial braking.
If the driver fails to take action despite having received an audible warning, Active Brake Assist with cross-traffic function will automatically initiate partial braking. This significantly reduces road speed and the driver receives an additional tactile warning. Partial braking can avoid a collision in the speed range below 30 km/h.
  • Autonomous full brake application.
If the driver still fails to react after braking has been triggered, Active Brake Assist can initiate autonomous braking - to the extent of maximum full-stop braking, if necessary. In the case of pedestrians, autonomous braking can additionally be initiated simultaneously with the warning, as appropriate to the given situation. In this way, a collision with pedestrians or stationary vehicles can be avoided up to an initial speed of 50 km/h. At higher initial speeds, Active Brake Assist helps to reduce the possible consequences of accidents.
