Detecting obstacles with assistance during collision risks

Updated 2021-10-15

Assistance during collision risks1 can help the driver detect different types of obstacles.

The function can detect pedestrians, cyclists or vehicles that are stationary or ahead and moving in the same direction as your vehicle. The function can also detect pedestrians, cyclists or large animals crossing the road in front of your vehicle.

Warning

Warnings and brake interventions may occur late or not at all. The driver is always responsible for ensuring that the vehicle is driven correctly and with a safety distance suitable for the speed.

Vehicles

For the function to be able to detect a vehicle in the dark, its headlights and taillights must be on and clearly visible.

Cyclists

For good performance, the system's camera and radar units for cyclist detection need the clearest possible information about the contours of the bicycle and of the cyclist's head, arm, shoulders, legs, torso and lower body in combination with normal human movements.

If large portions of the cyclist's body or the bicycle itself are not visible to the function's camera, it will not be able to detect a cyclist.

The system can only detect adult cyclists riding on bicycles intended for adults.

Warning

The function is supplementary driver support, but it cannot detect all cyclists in all situations and, for example, cannot see:

partially obscured cyclists.
cyclists if the contrast to the cyclist's background is poor.
cyclists in clothing that hides their body contour.
bikes loaded with large objects.

Pedestrians

For good performance, the system's camera and radar units for pedestrian detection need the clearest possible information about the contours of the pedestrian's head, arm, shoulders, legs, torso and lower body in combination with normal human movements.

In order to detect a pedestrian, there must be a contrast to the background, which could depend on clothing, weather conditions, etc. If there is little contrast, the person may be detected late or not at all, which may result in a delayed reaction from the system or no reaction at all.

The function can detect pedestrians even in dark conditions if they are illuminated by the vehicle's headlights.

Warning

The function is supplementary driver support, but it cannot detect all pedestrians in all situations and, for example, cannot see:

partially obscured pedestrians, people in clothing that hides their body contour or pedestrians shorter than 80 cm (32 tum).
pedestrians if the contrast to the pedestrian's background is poor.
pedestrians who are carrying large objects.

Large animals

P5-1617-s+v90 CitySafety Animal — Examples of what the function would interpret as a large animal: stationary or moving slowly and with clear body contours.

For good performance, the system's function for detecting large animals (e.g. moose, horses, etc.) needs the clearest possible information about body contours. This entails being able to detect the animal straight from the side in combination with normal movements for that animal.

If parts of the animal's body are not visible to the function's camera, the system will not be able to detect the animal.

The function can detect large animals even in dark conditions if they are illuminated by the vehicle's headlights.

Warning

The function is supplementary driver support, but it cannot detect all large animals in all situations and, for example, cannot see:

partially obscured larger animals.
larger animals seen from the front or from behind.
running or fast moving larger animals.
larger animals if the contrast to the animal's background is poor.
smaller animals such as cats and dogs.

Warnings and brake interventions may occur late or not at all. The driver is always responsible for ensuring that the vehicle is driven correctly and with a safety distance suitable for the speed.
