Two brains, one car - actively controlled steering

Actively controlled steering (ACS) systems enable vehicle autonomy and facilitate the trend in active stabilization and control that has been developing steadily over the last decade. These systems can improve the overall driving experience. Employing an on-board microprocessor, ACS is both a necessary enabler for fully autonomous vehicular operations and a functional element that can improve a car's operational envelope independent of autonomous operation. In the paper, examples of ACS are given, and BMW's active steering system and stability controllers based on ACS systems are discussed.
