What's Pedestrian Detection?

The world's first feature can prevent accidents involving pedestrians by automatically stopping the car if a person walks out in the street. This feature can detect pedestrians and will automatically avoid collisions at speeds up to 22 mph. The driver is first alerted by a sound signal together with a flashing light in the windshield's head-up display. In order to prompt an immediate, intuitive reaction, the visual warning is designed to look like a brake light coming on. If the driver does not respond to the warning and the system assesses that a collision is about to happen, the car's brakes are applied with full braking force. The car only brakes if it is too late to steer away and applies the brakes less than a second before the calculated impact time.

This sophisticated feature uses a combination of a radar sensor and a camera to identify standing or moving pedestrians within a 60° field of view in daylight. The radar detects objects of any shape and measure the distance to them. The camera determines what type of objects they are. To be able to classify an object as a pedestrian the sensing devices need to read an entire contour line of a human. The body has to be 31 inches or taller. Note that the detection can be disturbed if the human shape is distorted by certain clothes or if the person is carrying something.

Note!
The camera works like the human eye and can only see what the driver can see. Both radar and camera have limited fields of view and may be affected by for example rain, snow, road spray or low sun. If the initial distance to the object was too short, the warning may come too late while function of the support system in those cases can not be guaranteed. The driver is always responsible and in charge.
