Abstract

The present work deals with different control strategies for pivotable cameras for driver assistance systems. Camera-based systems for the perception of vehicle vicinity offer a high versatility. The system presented here uses a vehicle-fixed wide-angle camera and a pivotable camera with telephoto lens. The latter can be moved around two or three axes. As even small unintentioned movements of the tele camera can reduce image quality or lead to loss of image information, high positioning accuracy as well as low tracking errors are required for image processing. As friction is hard to control especially for small regulation errors, it is a problem in the given system. Besides classical control approaches a control strategy using nonlinear elements is considered. This strategy reaches high positioning accuracy and a low following error at quite low sample frequencies.
