Detecting obstacles with City Safety
Vehicles
City Safety detects most types of vehicles that are either stationary, moving in the same direction as your vehicle or those described in “City Safety in crossing traffic” and City Safety braking for oncoming vehicles”.
For City Safety to be able to detect a vehicle in the dark, its headlights and taillights must be on and clearly visible.
Cyclists
For optimal performance, the system's function for cyclist detection needs 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
- partially obscured cyclists.
- cyclists if the background contrast of the cyclist is poor - warning and brake interventions may then be late or not occur at all.
- cyclists in clothing that hides their body contour.
- bikes loaded with large objects.
The driver is always responsible for ensuring that the vehicle is driven correctly and with a safety distance suitable for the speed.
Pedestrians
For optimal performance, the system's function for pedestrian detection needs the clearest possible information about body and bicycle contours. This entails being able to detect 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.
City Safety can detect pedestrians even in dark conditions if they are illuminated by the vehicle's headlights.
Warning
- partially obscured pedestrians, people in clothing that hides their body contour or pedestrians shorter than 80 cm (32 in.).
- pedestrians if the background contrast of the pedestrians is poor - warning and brake interventions may then be late or not occur at all.
- pedestrians who are carrying large objects.
The driver is always responsible for ensuring that the vehicle is driven correctly and with a safety distance suitable for the speed.
Large animals
For optimal 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.
City Safety can detect large animals even in dark conditions if they are illuminated by the vehicle's headlights.
Warning
- partially obscured larger animals.
- larger animals seen from the front or from behind.
- running or fast moving larger animals.
- larger animals if the contrast of the animal's background is poor - warning and brake interventions may then occur late or not at all.
- smaller animals such as cats and dogs.
The driver is always responsible for ensuring that the vehicle is driven correctly and with a safety distance suitable for the speed.
