Design and analysis of an image-based ACC controller

It is an important aim to reduce the cost of driver assistance systems to bring their benefit in safety and comfort to as many drivers as possible. A single camera used as an environmental sensor has the potential for a significant cost reduction. Based on the currently available camera and image processing technology this work evaluates how the portfolio of the camera based assistance systems can be expanded by an ACC function. By transferring the method of image-based controlling from robotic to distance control of vehicles, a known controller for radar systems is adapted to the characteristics of the camera. The detailed analysis of the resulting controller shows the influence of the controller parameters on different aspects of the system behavior.
