Abstract
The invention relates to a method for tracking a target vehicle (9) approaching a motor vehicle (1) by means of a camera system (2) of the motor vehicle (1). A temporal sequence of images (10) of an environmental region of the motor vehicle (1) is provided by means of at least one camera (3) of the camera system (2). The target vehicle (9) is detected in an image (10) of the sequence by means of an image processing device (5) of the camera system (5) based on a feature of a front (11) or of a rear of the target vehicle (9) and then the target vehicle (9) is tracked over subsequent images (10) of the sequence based on the detected feature. Wherein at least a predetermined feature of a lateral flank (14) of the target vehicle (9) is detected in one of the subsequent images (10) of the sequence by the image processing device (5), and after detection of the feature of the lateral flank (14), the target vehicle (9) is tracked over further images (10) of the sequence based on the feature of the lateral flank (14).
