Abstract
Images of objects existing behind a first vehicle are detected to obtain distance data on the objects in relation to the first vehicle for recognizing one of the objects as a second vehicle travelling behind the first vehicle based on the distance data. The type of the second vehicle travelling behind is determined in size based on the images. It is further determined whether the second vehicle is an emergency vehicle based on the images.
