Collision warning system* - detection of cyclists

"Collision Warning with Auto Brake and Cyclist and Pedestrian Detection" is an aid to assist the driver when there is a risk of colliding with a pedestrian, bicycle or vehicle in front that are stationary or moving in the same direction.

The function only "sees" cyclists from behind, who are travelling in the same direction.

Optimum examples of what the system interprets as a cyclist - with clear body and bicycle contours, directly from behind and in the car's centre line.

Optimal performance of the system requires that the system function that detects a cyclist receives as unambiguous information as possible about the body and bicycle contours - this implies the opportunity to identify the bicycle, head, arms, shoulders, legs, upper and lower body combined with a normal human pattern of movement.

If large parts of the cyclist's body or bicycle are not visible to the function's camera then the system cannot detect a cyclist.

  • For the function to be able to detect a cyclist, he/she must be an adult and riding an "adult bicycle".
  • The bicycle must be equipped with a highly visible and approved1 rearward-facing red reflector, fitted at least 70 cm above the roadway.
  • The function can only detect cyclists directly from behind and who are travelling in the same direction - not at an angle from behind, not from the side.
  • Cyclists travelling on the left or right-hand edge of the car's imagined/extended side lines may be detected late or not at all.
  • The function's capacity to detect cyclists at dusk and dawn is limited - just like the human eye.
  • The function's capacity to detect cyclists is deactivated when driving in darkness and tunnels - even when streetlights are lit.
  • For optimum bicycle detection, the City Safety™ function must be activated, see City Safety™.


Collision Warning with Auto Brake & Cyclist Detection is a means of assistance.

The function cannot detect:

  • all cyclists in all situations and does not see partially obscured cyclists, for example.
  • cyclists in clothing that obscures the contours of the body or who are approaching from the side.
  • bicycles that have no rearward-facing red reflector.
  • bicycles loaded with large objects.

The driver is always responsible that the vehicle is driven properly and with a safety distance adapted to the speed.

  1. * Option/accessory.
  2. 1 The reflector must fulfil the recommendations and conditions of the traffic authority in the market in question.
